Making WAF Simple: Introducing the OWASP Compliance Dashboard
Whether you are a beginner or an expert, there is a truth that I want to let you in on; building and maintaining Web Application Firewall (WAF) security policies can be challenging. How much security do you really need? Is your configuration too much or too little? Have you created an operational nightmare? Many well-intentioned administrators will initially enable every available feature, thinking that it is providing additional security to the application, when in truth, it is hindering it. How, you may ask? False positives and noise. The more noise and false positives, the harder it becomes to find the real attacks and the increased likelihood that you begin disabling features that ARE providing essential security for your applications. So… less is better then? That isn't the answer either, what good are our security solutions if they aren't protecting against anything? The key to success and what we will look at further in this article, is implementing best practice controls that are both measurable and manageable for your organization. The OWASP Application Security Top 10 is a well-respected list of the ten most prevalent and dangerous application layer attacks that you almost certainly should protect your applications from. By first focusing your security controls on the items in the OWASP Top 10, you are improving the manageability of your security solution and getting the most "bang for your buck". Now, the challenge is, how do you take such a list and build real security protections for your applications? Introducing the OWASP Compliance Dashboard Protecting your applications against the OWASP Top 10 is not a new thing, in fact, many organizations have been taking this approach for quite some time. The challenge is that most implementations that claim to "protect" against the OWASP Top 10 rely solely on signature-based protections for only a small subset of the list and provide zero insight into your compliance status. The OWASP Compliance Dashboard introduced in version 15.0 on BIG-IP Advanced WAF reinvents this idea by providing a holistic and interactive dashboard that clearly measures your compliancy against the OWASP Application Security Top 10. The Top 10 is then broken down into specific security protections including both positive and negative security controls that can be enabled, disabled, or ignored directly on the dashboard. We realize that a WAF policy alone may not provide complete protection across the OWASP Top 10, this is why the dashboard also includes the ability to review and track the compliancy of best practices outside the scope of a WAF alone, such as whether the application is subject to routine patching or vulnerability scanning. To illustrate this, let’s assume I have created a brand new WAF policy using the Rapid Deployment policy template and accepted all default settings, what compliance score do you think this policy might have? Let's take a look. Interesting. The policy is 0/10 compliant and only A2 Broken Authentication and A3 Sensitive Data Exposure have partial compliance. Why is that? The Rapid Deployment template should include some protections by default, shouldn't it? Expanding A1 Injection, we see a list of protections required in order to be marked as compliant. Hovering over the list of attack signatures, we see that each category of signature is in 'Staging' mode, aha! Signatures in staging mode are not enforced and therefore cannot block traffic. Until the signature set is in enforced, we do not mark that protection as compliant. For those of you who have mistakenly left entities such as Signatures in staging for longer than desired, this is also a GREAT way to quickly find them. I also told you we could also interact with the dashboard to influence the compliancy score, lets demonstrate that. Each item can be enforced DIRECTLY on the dashboard by selecting the "Enforce" checkmark on the right. No need to go into multiple menus, you can enforce all these security settings on a single page and preview the compliance status immediately. If you are happy with your selection, click on "Review & Update" to perform a final review of what the dashboard will be configuring on your behalf before you can click on "Save & Apply Policy". Note: Enforcing signatures before a period of staging may not be a good idea depending on your environment. Staging provides a period to assess signature matches in order to eliminate false positives. Enforcing these signatures too quickly could result in the denying of legitimate traffic. Let's review the compliancy of our policy now with these changes applied. As you can see, A1 Injection is now 100% compliant and other categories have also had their score updated as a result of enforcing these signatures. The reason for this is because there is overlap in the security controls applied acrossthese other categories. Not all security controls can be fully implemented directly via the dashboard, and as mentioned previously, not all security controls are signature-based. A6 Cross-Site Scripting was recalculated as 50% complaint with the signatures we enforced previously so let's take a look at what else it required for full compliancy. The options available to us are to IGNORE the requirement, meaning we will be granted full compliancy for that item without implementing any protection, or we can manually configure the protection referenced. We may want to ignore a protection if it is not applicable to the application or if it is not in scope for your deployment. Be mindful that ignoring an item means you are potentially misrepresenting the score of your policy, be very certain that the protection you are ignoring is in fact not applicable before doing so. I've selected to ignore the requirement for "Disallowed Meta Characters in Parameters" and my policy is now 100% compliance for A7 Cross-Site Scripting (XSS). Lastly, we will look at items within the dashboard that fall outside the scope of WAF protections. Under A9 Using Components with Known Vulnerabilities, we are presented with a series of best practices such as “Application and system hardening”, “Application and system patching” and “Vulnerability scanner integration”. Using the dashboard, you can click on the checkmark to the right for "Requirement fulfilled" to indicate that your organization implements these best practices. By doing so, the OWASP Compliance score updates, providing you with real-time visibility into the compliancy for your application. Conclusion The OWASP Compliance Dashboard on BIG-IP Advanced WAF is a perfect fit for the security administrator looking to fine-tune and measure either existing or new WAF policies against the OWASP App Security Top 10. The OWASP Compliance Dashboard not only tracks WAF-specific security protections but also includes general best practices, allowing you to use the dashboard as your one-stop-shop to measure the compliancy for ALL your applications. For many applications, protection against the OWASP Top 10 may be enough, as it provides you with best practices to follow without having to worry about which features to implement and where. Note: Keep in mind that some applications may require additional controls beyond the protections included in the OWASP Top 10 list. For teams heavily embracing automation and CI/CD pipelines, logging into a GUI to perform changes likely does not sound appealing. In that case, I suggest reading more about our Declarative Advanced WAF policy framework which can be used to represent the WAF policies in any CI/CD pipeline. Combine this with the OWASP Compliance Dashboard for an at-a-glance assessment of your policy and you have the best of both worlds. If you're not already using the OWASP Compliance Dashboard, what are you waiting for? Look out for Bill Brazill, Victor Granic and myself (Kyle McKay) on June 10th at F5 Agility 2020 where we will be presenting and facilitating a class called "Protecting against the OWASP Top 10". In this class, we will be showcasing the OWASP Compliance Dashboard on BIG-IP Advanced WAF further and providing ample hands-on time fine-tuning and measuring WAF policies for OWASP Compliance.

Problem this snippet solves: This iApp template helps you configure BIG-IP to support security controls consonant with NIST Special Publication 800-53r4. This iApp focuses on management of the BIG-IP itself rather than control of application traffic through the BIG-IP. For more details on this iApp and how it supports NIST Special Publication 800-53r4, enable the Inline Help within the template. The Help tab in the GUI contains additional information. The associated deployment guide is now available at http://www.f5.com/pdf/deployment-guides/nist-sp-800-53-r4-dg.pdf Fully supported version v1.0.0 - Supported release Released the fully supported version of the NIST iApp on 02-08-17. There were no additional changes to the iApp template over RC-6, however the iApp now supports BIG-IP versions 11.5.3 - 12.1.2. See https://support.f5.com/csp/article/K09154349 for instructions on downloading, importing and using the iApp. Release Candidate versions v1.0.1rc3 and rc4 RC3 was released on downloads.f5.com with a single fix (corrected an issue where the iApp would incorrectly detect Appliance Mode). As a part of this fix, the iApp would not load on BIG-IP systems that had a previous version of the NIST iApp. F5 released RC4 on DevCentral with a fix for this issue, and now the iApp loads properly on all devices. This version also contains a fix for multi-line banners and a fix for SNMP so the iApp catches any form of 127.0.0.0 and maps it. Released 1.0.1rc4 of the NIST iApp on 06-18-2018. v1.0.1rc1 Released 1.0.1rc1 of the NIST iApp on 08-18-2017. This version corrects an issue that would cause iApp Failure when configuring custom ports for self IP port lockdown v1.0.0rc6 Released RC-6 of the NIST iApp on 12-12-2016. In RC-6, all customer secrets/passwords in the iApp template are now securely stored. Previously, although secrets were stored in Secure Vault for use, some may have been stored in cleartext in the iApp reconfiguration data.* Added support for BIG-IP versions 12.1 and 12.1.1. Made error messages produced by the template easier to understand. If using RADIUS authentication, you are now limited a maximum of 10 servers. Previously there was no limit. The source-IP option on additional syslog servers is honored in this version. Previously this field was ignored. v1.0.0rc5 Released RC-5 of the NIST iApp on 12-16-2015. RC-5 adds a new question to the iApp template if you specified LDAP as your authentication method, asking if the directory user objects include group-membership attributes (like memberOf). Adds All as an option for remote-role partition access Other minor bug fixes. v1.0.0rc4 Released RC-4 of the NIST iApp on 12-02-2015. RC-4 adds support for BIG-IP v11.5.3. The main difference is the "Fraud Protection Manager" role was not available in 11.5.3, and only v11.6 and later.* Added the iRule Manager role that was missing in previous versions of the iApp. Clarified the answers and inline help for the MCPD audit log section. v1.0.0rc3 Released RC-3 of the NIST iApp on 11-12-2015. RC-3 contains mostly clarifications to the iApp presentation, including question/answer text and the inline help. Added warning messages where applicable. For the Management Access and SNMP Access IP addresses sections, removed the option to not allow any IP addresses, as this could cause issues, such as users inadvertently locking themselves out of the system. v1.0.0rc2 Released RC-2 of the NIST iApp on 10-30-2015. RC-2 corrects an issue where the option to revert to the pre-iApp configuration was not working properly.* Enhanced the management of self-IP access policies. Changes are now saved as the default for use with new self-IP objects as well as applied to existing self IP objects. Code : 88573
Inspec/Rspec Tests and Compliance BigIp f5
Anyone doing any work at the moment with inspec tests for f5's? Started using inspec and pretty quick to write tests in a ruby container, but seems no native stuff for f5, other than rolling my own with the rest api? *tried searching already* - maybe there are other resources someone can help with? Thanks in advance.Complying with PCI DSS–Part 1: Build and Maintain a Secure Network
According to the PCI SSC, there are 12 PCI DSS requirements that satisfy a variety of security goals. Areas of focus include building and maintaining a secure network, protecting stored cardholder data, maintaining a vulnerability management program, implementing strong access control measures, regularly monitoring and testing networks, and maintaining information security policies. The essential framework of the PCI DSS encompasses assessment, remediation, and reporting. Over the next several blogs, we’ll explore how F5 can help organizations gain or maintain compliance. Today is Build and Maintain a Secure Network which includes PCI Requirements 1 and 2. PCI DSS Quick Reference Guide, October 2010 The PCI DSS requirements apply to all “system components,” which are defined as any network component, server, or application included in, or connected to, the cardholder data environment. Network components include, but are not limited to, firewalls, switches, routers, wireless access points, network appliances, and other security appliances. Servers include, but are not limited to, web, database, authentication, DNS, mail, proxy, and NTP servers. Applications include all purchased and custom applications, including internal and external web applications. The cardholder data environment is a combination of all the system components that come together to store and provide access to sensitive user financial information. F5 can help with all of the core PCI DSS areas and 10 of its 12 requirements. Requirement 1: Install and maintain a firewall and router configuration to protect cardholder data. PCI DSS Quick Reference Guide description: Firewalls are devices that control computer traffic allowed into and out of an organization’s network, and into sensitive areas within its internal network. Firewall functionality may also appear in other system components. Routers are hardware or software that connects two or more networks. All such devices are in scope for assessment of Requirement 1 if used within the cardholder data environment. All systems must be protected from unauthorized access from the Internet, whether via e-commerce, employees’ remote desktop browsers, or employee email access. Often, seemingly insignificant paths to and from the Internet can provide unprotected pathways into key systems. Firewalls are a key protection mechanism for any computer network. Solution: F5 BIG-IP products provide strategic points of control within the Application Delivery Network (ADN) to enable truly secure networking across all systems and network and application protocols. The BIG-IP platform provides a unified view of layers 3 through 7 for both general reporting and alerts and those required by ICSA Labs, as well as for integration with products from security information and event management (SIEM) vendors. BIG-IP Local Traffic Manager (LTM) offers native, high-performance firewall services to protect the entire infrastructure. BIG-IP LTM is a purpose-built, high-performance Application Delivery Controller (ADC) designed to protect Internet data centers. In many instances, BIG-IP LTM can replace an existing firewall while also offering scalability, performance, and persistence. Running on an F5 VIPRION chassis, BIG-IP LTM can manage up to 48 million concurrent connections and 72 Gbps of throughput with various timeout behaviors and buffer sizes when under attack. It protects UDP, TCP, SIP, DNS, HTTP, SSL, and other network attack targets while delivering uninterrupted service for legitimate connections. The BIG-IP platform, which offers a unique Layer 2–7 security architecture and full packet inspection, is an ICSA Labs Certified Network Firewall. Replacing stateful firewall services with BIG-IP LTM in the data center architecture Requirement 2: Do not use vendor-supplied defaults for system passwords and other security parameters. PCI DSS Quick Reference Guide description: The easiest way for a hacker to access your internal network is to try default passwords or exploits based on the default system software settings in your payment card infrastructure. Far too often, merchants do not change default passwords or settings upon deployment. This is akin to leaving your store physically unlocked when you go home for the night. Default passwords and settings for most network devices are widely known. This information, combined with hacker tools that show what devices are on your network, can make unauthorized entry a simple task if you have failed to change the defaults. Solution: All F5 products allow full access for administrators to change all forms of access and service authentication credentials, including administrator passwords, application service passwords, and system monitoring passwords (such as SNMP). Products such as BIG-IP Access Policy Manager (APM) and BIG-IP Edge Gateway limit remote connectivity to only a GUI and can enforce two-factor authentication, allowing tighter control over authenticated entry points. The BIG-IP platform allows the administrator to open up specific access points to be fitted into an existing secure network. BIG-IP APM and BIG-IP Edge Gateway offer secure, role-based administration (SSL/TLS and SSH protocols) and virtualization for designated access rights on a per-user or per-group basis. Secure Vault, a hardware-secured encrypted storage system introduced in BIG-IP version 9.4.5, protects critical data using a hardware-based key that does not reside on the appliance’s file system. In BIG-IP v11, companies have the option of securing their cryptographic keys in hardware, such as a FIPS card, rather than encrypted on the BIG-IP hard drive. The Secure Vault feature can also encrypt certificate passwords for enhanced certificate and key protection in environments where FIPS 140-2 hardware support is not required, but additional physical and role-based protection is preferred. Secure Vault encryption may also be desirable when deploying the virtual editions of BIG-IP products, which do not support key encryption on hardware. Next: Protect Cardholder Data psVulnerability Assessment with Application Security
The longer an application remains vulnerable, the more likely it is to be compromised. Protecting web applications is an around-the-clock job. Almost anything that is connected to the Internet is a target these days, and organizations are scrambling to keep their web properties available and secure. The ramifications of a breach or downtime can be severe: brand reputation, the ability to meet regulatory requirements, and revenue are all on the line. A 2011 survey conducted by Merrill Research on behalf of VeriSign found that 60 percent of respondents rely on their websites for at least 25 percent of their annual revenue. And the threat landscape is only getting worse. Targeted attacks are designed to gather intelligence; steal trade secrets, sensitive customer information, or intellectual property; disrupt operations; or even destroy critical infrastructure. Targeted attacks have been around for a number of years, but 2011 brought a whole new meaning to advanced persistent threat. Symantec reported that the number of targeted attacks increased almost four-fold from January 2011 to November 2011. In the past, the typical profile of a target organization was a large, well-known, multinational company in the public, financial, government, pharmaceutical, or utility sector. Today, the scope has widened to include almost any size organization from any industry. The attacks are also layered in that the malicious hackers attempt to penetrate both the network and application layers. To defend against targeted attacks, organizations can deploy a scanner to check web applications for vulnerabilities such as SQL injection, cross site scripting (XSS), and forceful browsing; or they can use a web application firewall (WAF) to protect against these vulnerabilities. However a better, more complete solution is to deploy both a scanner and a WAF. BIG-IP Application Security Manager (ASM) version 11.1 is a WAF that gives organizations the tools they need to easily manage and secure web application vulnerabilities with multiple web vulnerability scanner integrations. As enterprises continue to deploy web applications, network and security architects need visibility into who is attacking those applications, as well as a big-picture view of all violations to plan future attack mitigation. Administrators must be able to understand what they see to determine whether a request is valid or an attack that requires application protection. Administrators must also troubleshoot application performance and capacity issues, which proves the need for detailed statistics. With the increase in application deployments and the resulting vulnerabilities, administrators need a proven multi-vulnerability assessment and application security solution for maximum coverage and attack protection. But as many companies also support geographically diverse application users, they must be able to define who is granted or denied application access based on geolocation information. Application Vulnerability Scanners To assess a web application’s vulnerability, most organizations turn to a vulnerability scanner. The scanning schedule might depend on a change control, like when an application is initially being deployed, or other factors like a quarterly report. The vulnerability scanner scours the web application, and in some cases actually attempts potential hacks to generate a report indicating all possible vulnerabilities. This gives the administrator managing the web security devices a clear view of all the exposed areas and potential threats to the website. It is a moment-in-time report and might not give full application coverage, but the assessment should give administrators a clear picture of their web application security posture. It includes information about coding errors, weak authentication mechanisms, fields or parameters that query the database directly, or other vulnerabilities that provide unauthorized access to information, sensitive or not. Many of these vulnerabilities would need to be manually re-coded or manually added to the WAF policy—both expensive undertakings. Another challenge is that every web application is different. Some are developed in .NET, some in PHP or PERL. Some scanners execute better on different development platforms, so it’s important for organizations to select the right one. Some companies may need a PCI DSS report for an auditor, some for targeted penetration testing, and some for WAF tuning. These factors can also play a role in determining the right vulnerability scanner for an organization. Ease of use, target specifics, and automated testing are the baselines. Once an organization has considered all those details, the job is still only half done. Simply having the vulnerability report, while beneficial, doesn’t mean a web app is secure. The real value of the report lies in how it enables an organization to determine the risk level and how best to mitigate the risk. Since re-coding an application is expensive and time-consuming, and may generate even more errors, many organizations deploy a web application firewall like BIG-IP ASM. A WAF enables an organization to protect its web applications by virtually patching the open vulnerabilities until it has an opportunity to properly close the hole. Often, organizations use the vulnerability scanner report to then either tighten or initially generate a WAF policy. Attackers can come from anywhere, so organizations need to quickly mitigate vulnerabilities before they become threats. They need a quick, easy, effective solution for creating security policies. Although it’s preferable to have multiple scanners or scanning services, many companies only have one, which significantly impedes their ability to get a full vulnerability assessment. Further, if an organization’s WAF and scanner aren’t integrated, neither is its view of vulnerabilities, as a non-integrated WAF UI displays no scanner data. Integration enables organizations both to manage the vulnerability scanner results and to modify the WAF policy to protect against the scanner’s findings—all in one UI. Integration Reduces Risk While finding vulnerabilities helps organizations understand their exposure, they must also have the ability to quickly mitigate found vulnerabilities to greatly reduce the risk of application exploits. The longer an application remains vulnerable, the more likely it is to be compromised. F5 BIG-IP ASM, a flexible web application firewall, enables strong visibility with granular, session-based enforcement and reporting; grouped violations for correlation; and a quick view into valid and attack requests. BIG-IP ASM delivers comprehensive vulnerability assessment and application protection that can quickly reduce web threats with easy geolocation-based blocking—greatly improving the security posture of an organization’s critical infrastructure. BIG-IP ASM version 11.1 includes integration with IBM Rational AppScan, Cenzic Hailstorm, QualysGuard WAS, and WhiteHat Sentinel, building more integrity into the policy lifecycle and making it the most advanced vulnerability assessment and application protection on the market. In addition, administrators can better create and enforce policies with information about attack patterns from a grouping of violations or otherwise correlated incidents. In this way, BIG-IP ASM enables organizations to mitigate threats in a timely manner and greatly reduce the overall risk of attacks and solve most vulnerabilities. With multiple vulnerability scanner assessments in one GUI, administrators can discover and remediate vulnerabilities within minutes from a central location. BIG-IP ASM offers easy policy implementation, fast assessment and policy creation, and the ability to dynamically configure policies in real time during assessment. To significantly reduce data loss, administrators can test and verify vulnerabilities from the BIG-IP ASM GUI, and automatically create policies with a single click to mitigate unknown application vulnerabilities. Security is a never-ending battle. The bad guys advance, organizations counter, bad guys cross over—and so the cat and mouse game continues. The need to properly secure web applications is absolute. Knowing what vulnerabilities exist within a web application can help organizations contain possible points of exposure. BIG-IP ASM v11.1 offers unprecedented web application protection by integrating with many market-leading vulnerability scanners to provide a complete vulnerability scan and remediate solution. BIG-IP ASM v11.1 enables organizations to understand inherent threats and take specific measures to protect their web application infrastructure. It gives them the tools they need to greatly reduce the risk of becoming the next failed security headline. ps Resources: F5’s Certified Firewall Protects Against Large-Scale Cyber Attacks on Public-Facing Websites IPS or WAF Dilemma F5 Case Study: WhiteHat Security Oracle OpenWorld 2011: BIG-IP ASM & Oracle Database Firewall Audio White Paper - Application Security in the Cloud with BIG-IP ASM The Big Attacks are Back…Not That They Ever Stopped Protection from Latest Network and Application Attacks The New Data Center Firewall Paradigm – White Paper Vulnerability Assessment with Application Security – White Paper F5 Security Vignette: Hacktivism Attack – Video F5 Security Vignette: DNSSEC Wrapping – Video Jeremiah Grossman blog Technorati Tags: F5, big-ip, virtualization, cloud computing, Pete Silva, security, waf, web scanners, compliance, application security, internet, TMOS, big-ip, asmComplying with PCI DSS–Part 5: Regularly Monitor and Test Networks
According to the PCI SSC, there are 12 PCI DSS requirements that satisfy a variety of security goals. Areas of focus include building and maintaining a secure network, protecting stored cardholder data, maintaining a vulnerability management program, implementing strong access control measures, regularly monitoring and testing networks, and maintaining information security policies. The essential framework of the PCI DSS encompasses assessment, remediation, and reporting. We’re exploring how F5 can help organizations gain or maintain compliance and today is Regularly Monitor and Test Networks which includes PCI Requirements 10 and 11. To read Part 1, click: Complying with PCI DSS–Part 1: Build and Maintain a Secure Network, Part 2:Complying with PCI DSS–Part 2: Protect Cardholder Data, Part 3: Complying with PCI DSS–Part 3: Maintain a Vulnerability Management Program and Part 4: Complying with PCI DSS–Part 4: Implement Strong Access Control Measures. Requirement 10: Track and monitor all access to network resources and cardholder data. PCI DSS Quick Reference Guide description: Logging mechanisms and the ability to track user activities are critical for effective forensics and vulnerability management. The presence of logs in all environments allows thorough tracking and analysis if something goes wrong. Determining the cause of a compromise is very difficult without system activity logs. Solution: The spirit of this requirement is to ensure appropriate systems generate logs, with implementation and monitoring of log aggregation and correlation systems. The ability to monitor and log all user sessions and requests for access to sensitive information, such as cardholder data and Social Security numbers, is critical to any security environment. F5 offers a suite of solutions that are session-based, not packet-based. With this full reverse proxy architecture, the BIG-IP platform has the ability to manage full user sessions, regardless of the transport mechanism or network, and match those user sessions to specific data actions, supplying log data and a full audit trail from the user to the data. This allows F5 application security devices to ensure the confidentiality, integrity, and availability of all application data on the network. All F5 products support remote logging, allowing logs to be pushed to secure networks and devices for archiving. In addition, the TMOS architecture can manage isolated, secure logging networks in conjunction with the application networks, using features such as mirrored ports, VLANs, and virtualized administrative access. Protecting network resources and application data 24 hours a day, seven days a week, without affecting network performance, is a core function and the foundation of all F5 security products. Requirement 11: Regularly test security systems and processes. PCI DSS Quick Reference Guide description: Vulnerabilities are being discovered continually by malicious individuals and researchers, and being introduced by new software. System components, processes, and custom software should be tested frequently to ensure security is maintained over time. Testing of security controls is especially important for any environmental changes such as deploying new software or changing system configuration. Solution: The spirit of this requirement is to ensure that the complying organization itself tests its security system and processes. Since F5 does not offer a penetration testing service, this is one of just two PCI DSS requirements that F5 products cannot significantly address. Next: Maintain an Information Security Policy psFedRAMP Federates Further
FedRAMP (Federal Risk and Authorization Management Program), the government’s cloud security assessment plan, announced late last week that Amazon Web Services (AWS) is the first agency-approved cloud service provider. The accreditation covers all AWS data centers in the United States. Amazon becomes the third vendor to meet the security requirements detailed by FedRAMP. FedRAMP is the result of the US Government’s work to address security concerns related to the growing practice of cloud computing and establishes a standardized approach to security assessment, authorizations and continuous monitoring for cloud services and products. By creating industry-wide security standards and focusing more on risk management, as opposed to strict compliance with reporting metrics, officials expect to improve data security as well as simplify the processes agencies use to purchase cloud services. FedRAMP is looking toward full operational capability later this year. As both the cloud and the government’s use of cloud services grow, officials found that there were many inconsistencies to requirements and approaches as each agency began to adopt the cloud. Launched in 2012, FedRAMP’s goal is to bring consistency to the process but also give cloud vendors a standard way of providing services to the government. And with the government’s cloud-first policy, which requires agencies to consider moving applications to the cloud as a first option for new IT projects, this should streamline the process of deploying to the cloud. This is an ‘approve once, and use many’ approach, reducing the cost and time required to conduct redundant, individual agency security assessment. AWS's certification is for 3 years. FedRAMP provides an overall checklist for handling risks associated with Web services that would have a limited, or serious impact on government operations if disrupted. Cloud providers must implement these security controls to be authorized to provide cloud services to federal agencies. The government will forbid federal agencies from using a cloud service provider unless the vendor can prove that a FedRAMP-accredited third-party organization has verified and validated the security controls. Once approved, the cloud vendor would not need to be ‘re-evaluated’ by every government entity that might be interested in their solution. There may be instances where additional controls are added by agencies to address specific needs. The BIG-IP Virtual Edition for AWS includes options for traffic management, global server load balancing, application firewall, web application acceleration, and other advanced application delivery functions. ps Related: Cloud Security With FedRAMP FedRAMP Ramps Up FedRAMP achieves another cloud security milestone Amazon wins key cloud security clearance from government Cloud Security With FedRAMP CLOUD SECURITY ACCREDITATION PROGRAM TAKES FLIGHT FedRAMP comes fraught with challenges F5 iApp template for NIST Special Publication 800-53 Now Playing on Amazon AWS - BIG-IP Connecting Clouds as Easy as 1-2-3 F5 Gives Enterprises Superior Application Control with BIG-IP Solutions for Amazon Web Services Technorati Tags: f5,fedramp,government,cloud,service providers,risk,standards,silva,compliance,cloud security,aws,amazon Connect with Peter: Connect with F5:Complying with PCI DSS–Part 3: Maintain a Vulnerability Management Program
According to the PCI SSC, there are 12 PCI DSS requirements that satisfy a variety of security goals. Areas of focus include building and maintaining a secure network, protecting stored cardholder data, maintaining a vulnerability management program, implementing strong access control measures, regularly monitoring and testing networks, and maintaining information security policies. The essential framework of the PCI DSS encompasses assessment, remediation, and reporting. We’re exploring how F5 can help organizations gain or maintain compliance and today is Maintain a Vulnerability Management Program which includes PCI Requirements 5 and 6. To read Part 1, click: Complying with PCI DSS–Part 1: Build and Maintain a Secure Network and Part 2: Complying with PCI DSS–Part 2: Protect Cardholder Data Requirement 5: Use and regularly update antivirus software or programs. PCI DSS Quick Reference Guide description: Vulnerability management is the process of systematically and continuously finding weaknesses in an entity’s payment card infrastructure system. This includes security procedures, system design, implementation, or internal controls that could be exploited to violate system security policy. Solution: With BIG-IP APM and BIG-IP Edge Gateway, F5 provides the ability to scan any remote device or internal system to ensure that an updated antivirus package is running prior to permitting a connection to the network. Once connections are made, BIG-IP APM and BIG-IP Edge Gateway continually monitor the user connections for a vulnerable state change, and if one is detected, can quarantine the user on the fly into a safe, secure, and isolated network. Remediation services can include a URL redirect to an antivirus update server. For application servers in the data center, BIG-IP products can communicate with existing network security and monitoring tools. If an application server is found to be vulnerable or compromised, that device can be automatically quarantined or removed from the service pool. With BIG-IP ASM, file uploads can be extracted from requests and transferred over iCAP to a central antivirus (AV) scanner. If a file infection is detected, BIG-IP ASM will drop that request, making sure the file doesn’t reach the web server. Requirement 6: Develop and maintain secure systems and applications. PCI DSS Quick Reference Guide description: Security vulnerabilities in systems and applications may allow criminals to access PAN and other cardholder data. Many of these vulnerabilities are eliminated by installing vendor-provided security patches, which perform a quick-repair job for a specific piece of programming code. All critical systems must have the most recently released software patches to prevent exploitation. Entities should apply patches to less-critical systems as soon as possible, based on a risk-based vulnerability management program. Secure coding practices for developing applications, change control procedures, and other secure software development practices should always be followed. Solution: Requirements 6.1 through 6.5 deal with secure coding and application development; risk analysis, assessment, and mitigation; patching; and change control. Requirement 6.6 states: “Ensure all public-facing web applications are protected against known attacks, either by performing code vulnerability reviews at least annually or by installing a web application firewall in front of public-facing web applications.” This requirement can be easily met with BIG-IP ASM, which is a leading web application firewall (WAF) offering protection for vulnerable web applications. Using both a positive security model for dynamic application protection and a strong, signature-based negative security model, BIG-IP ASM provides application-layer protection against both targeted and generalized application attacks. It also protects against the Open Web Application Security Project (OWASP) Top Ten vulnerabilities and threats on the Web Application Security Consortium’s (WASC) Threat Classification lists. To assess a web application’s vulnerability, most organizations turn to a vulnerability scanner. The scanning schedule might depend on a change in control, as when an application is initially being deployed, or other triggers such as a quarterly report. The vulnerability scanner scours the web application, and in some cases actually attempts potential attacks, to generate a report indicating all possible vulnerabilities. This gives the administrator managing the web security devices a clear view of all exposed areas and potential threats to the website. Such a report is a moment-in time assessment and might not result in full application coverage, but should give administrators a clear picture of their web application security posture. It includes information about coding errors, weak authentication mechanisms, fields or parameters that query the database directly, or other vulnerabilities that provide unauthorized access to information, sensitive or not. Otherwise, many of these vulnerabilities would need to be manually re-coded or manually added to the WAF policy—both expensive undertakings. Simply having the vulnerability report, while beneficial, doesn’t make a web application secure. The real value of the report lies in how it enables an organization to determine the risk level and how best to mitigate the risk. Since recoding an application is expensive and time-consuming and may generate even more errors, many organizations deploy a WAF like BIG-IP ASM. A WAF enables an organization to protect its web applications by virtually patching the open vulnerabilities until developers have an opportunity to properly close the hole. Often, organizations use the vulnerability scanner report to either tighten or initially generate a WAF policy. While finding vulnerabilities helps organizations understand their exposure, they must also have the ability to quickly mitigate those vulnerabilities to greatly reduce the risk of application exploits. The longer an application remains vulnerable, the more likely it is to be compromised. For cloud deployments, BIG-IP ASM Virtual Edition (VE) delivers the same functionality as the physical edition and helps companies maintain compliance, including compliance with PCI DSS, when they deploy applications in the cloud. If an application vulnerability is discovered, BIG-IP ASM VE can quickly be deployed in a cloud environment, enabling organizations to immediately patch vulnerabilities virtually until the development team can permanently fix the application. Additionally, organizations are often unable to fix applications developed by third parties, and this lack of control prevents many of them from considering cloud deployments. But with BIG-IP ASM VE, organizations have full control over securing their cloud infrastructure. BIG-IP ASM version 11.1 includes integration with IBM Rational AppScan, Cenzic Hailstorm, QualysGuard WAS, and WhiteHat Sentinel, making BIG-IP ASM the most advanced vulnerability assessment and application protection on the market. In addition, administrators can better create and enforce policies with information about attack patterns from a grouping of violations or otherwise correlated incidents. In this way, BIG-IP ASM protects the applications between scanning and patching cycles and against zero-day attacks that signature-based scanners won’t find. Both are critical in creating a secure Application Delivery Network. BIG-IP ASM also makes it easy to understand where organizations stand relative to PCI DSS compliance. With the BIG-IP ASM PCI Compliance Report, organizations can quickly see each security measure required to comply with PCI DSS 2.0 and understand which measures are or are not relevant to BIG-IP ASM functions. For relevant security measures, the report indicates whether the organization’s BIG-IP ASM appliance complies with PCI DSS 2.0. For security measures that are not relevant to BIG-IP ASM, the report explains what action to take to achieve PCI DSS 2.0 compliance. BIG-IP ASM PCI Compliance Report Finally, with the unique F5 iHealth system, organizations can analyze the configuration of their BIG-IP products to identify any critical patches or security updates that may be necessary. Next: Implement Strong Access Control Measures psComplying with PCI DSS–Part 2: Protect Cardholder Data
According to the PCI SSC, there are 12 PCI DSS requirements that satisfy a variety of security goals. Areas of focus include building and maintaining a secure network, protecting stored cardholder data, maintaining a vulnerability management program, implementing strong access control measures, regularly monitoring and testing networks, and maintaining information security policies. The essential framework of the PCI DSS encompasses assessment, remediation, and reporting. We’re exploring how F5 can help organizations gain or maintain compliance and today is Protect Cardholder Data which includes PCI Requirements 3 and 4. To read Part 1, click: Complying with PCI DSS–Part 1: Build and Maintain a Secure Network Requirement 3: Protect stored cardholder data. PCI DSS Quick Reference Guide description: In general, no cardholder data should ever be stored unless it’s necessary to meet the needs of the business. Sensitive data on the magnetic stripe or chip must never be stored. If your organization stores PAN, it is crucial to render it unreadable, for instance, [by] obfuscation [or] encryption. Solution: The spirit of this requirement is encryption-at-rest—protecting stored cardholder data. While F5 products do not encrypt data at rest, the BIG-IP platform has full control over the data and network path, allowing the devices to secure data both in and out of the application network. F5 iSession tunnels create a site-to-site secure connection between two BIG-IP devices to accelerate and encrypt data transfer over the WAN. With BIG-IP APM and BIG-IP Edge Gateway, data can be encrypted between users and applications, providing security for data in transit over the Internet. BIG-IP APM and BIG-IP Edge Gateway can also provide a secure access path to, and control, restricted storage environments where the encryption keys are held (such as connecting a point-of-sale [POS] device to a secure back-end database to protect data in transit over insecure networks such as WiFi or mobile). With BIG-IP Application Security Manager (ASM), data such as the primary account number (PAN) can be masked when delivered and displayed outside of the secure ADN. BIG-IP ASM also can mask such data within its logs and reporting, ensuring that even the administrator will not be able to see it. Requirement 4: Encrypt transmission of cardholder data across open, public networks. PCI DSS Quick Reference Guide description: Cyber criminals may be able to intercept transmissions of cardholder data over open, public networks, so it is important to prevent their ability to view this data. Encryption is a technology used to render transmitted data unreadable by any unauthorized person. Solution: The modular BIG-IP system is built on the F5 TMOS full-proxy operating system, which enables bi-directional data flow protection and selective TLS/SSL encryption. All or selective parts of the data stream can be masked and/or TLS/SSL encrypted on all parts of the delivery network. The BIG-IP platform supports both SSL termination, decrypting data traffic with the user for clear-text delivery on the ADN, and SSL proxying, decrypting data traffic on BIG-IP devices for content inspection and security before re-encrypting the data back on the wire in both directions. The BIG-IP platform, along with the F5 iRules scripting language, also supports specific data string encryption via publicly tested and secure algorithms, allowing the enterprise to selectively encrypt individual data values for delivery on the wire or for secure back-end storage. The BIG-IP® Edge Client software module, offered with BIG-IP APM and BIG-IP Edge Gateway or as a mobile application, can encrypt any and all connections from the client to the BIG-IP device. Customers have customized and installed BIG-IP Edge Client on ATMs and currency or coin counting kiosks to allow those devices to securely connect to a central server. In addition, two BIG-IP devices can create an iSession tunnel to create a site-to-site connection to secure and accelerate data transfer over the WAN. iSession tunnels create a site-to-site secure connection to accelerate data transfer over the WAN Next: Maintain a Vulnerability Management Program ps
