Virtual Server requires a profile type web security
Recently upgraded from 11.5.1 to 12.1.2 and having issues with Outlook Anywhere. This is configured via an Exchange iAPP. When I try to reconfigure the iApp I get the following error: "Virtual Server requires a profile type web security for ltm policy xxx" Where does this profile reside in the GUI? Also if the profile is created and iApp reconfigured is this service impacting? Thanks in advance.ICSA Certified Network Firewall for Data Centers
The BIG-IP platform is now ICSA Certified as a Network Firewall. Internet threats are widely varied and multi-layered. Although applications and their data are attackers’ primary targets, many attackers gain entry at the network layer. Internet data centers and public-facing web properties are constant targets for large-scale attacks by hacker/hactivist communities and others looking to grab intellectual property or cause a service outage. Organizations must prepare for the normal influx of users, but they also must defend their infrastructure from the daily barrage of malicious users. Security administrators who manage large web properties are struggling with security because traditional firewalls are not meeting their fundamental performance needs. Dynamic and layered attacks that necessitate multiple-box solutions, add to IT distress. Traditional firewalls can be overwhelmed by their limited ability to scale under a DDoS attack while keeping peak connection performance for valid users, which renders not only the firewalls themselves unresponsive, but the web sites they are supposed to protect. Additionally, traditional firewalls’ limited capacity to interpret context means they may be unable to make an intelligent decision about how to deliver the application while also keeping services available for valid requests during a DDoS attack. Traditional firewalls also lack specialized capabilities like SSL offload, which not only helps reduce the load on the web servers, but enables inspection, re-encryption, and certificate storage. Most traditional firewalls lack the agility to react quickly to changes and emerging threats, and many have only limited ability to provide new services such as IP geolocation, traffic redirection, traffic manipulation, content scrubbing, and connection limiting. An organization’s inability to respond to these threats dynamically, and to minimize the exposure window, means the risk to the overall business is massive. There are several point solutions in the market that concentrate on specific problem areas; but this creates security silos that only make management and maintenance more costly, more cumbersome, and less effective. The BIG-IP platform provides a unified view of layer 3 through 7 for both general and ICSA required reporting and alerts, as well as integration with SIEM vendors. BIG-IP Local Traffic Manager offers native, high-performance firewall services to protect the entire infrastructure. BIG-IP LTM is a purpose-built, high-performance Application Delivery Controller designed to protect Internet data centers. In many instances, BIG-IP LTM can replace an existing firewall while also offering scale, performance, and persistence. Performance: BIG-IP LTM manages up to 48 million concurrent connections and 72 Gbps of throughput with various timeout behaviors, buffer sizes, and more when under attack. Protocol security: The BIG-IP system natively decodes IPv4, IPv6, TCP, HTTP, SIP, DNS, SMTP, FTP, Diameter, and RADIUS. Organizations can control almost every element of the protocols they’re deploying. DDoS prevention capabilities: An integrated architecture enables organizations to combine traditional firewall layers 3 and 4 with application layers 5 through 7. DDoS mitigations: The BIG-IP system protects UDP, TCP, SIP, DNS, HTTP, SSL, and other network attack targets while delivering uninterrupted service for legitimate connections. SSL termination: Offload computationally intensive SSL to the BIG-IP system and gain visibility into potentially harmful encrypted payloads. Dynamic threat mitigation: iRules provide a flexible way to enforce protocol functions on both standard and emerging or custom protocols. With iRules, organizations can create a zero day dynamic security context to react to vulnerabilities for which an associated patch has not yet been released. Resource cloaking and content security: Prevent leaks of error codes and sensitive content. F5 BIG-IP LTM has numerous security features so Internet data centers can deliver applications while protecting the infrastructure that supports their clients and, BIG-IP is now ICSA Certified as a Network Firewall. ps Resources: F5’s Certified Firewall Protects Against Large-Scale Cyber Attacks on Public-Facing Websites F5 BIG-IP Data Center Firewall – Overview BIG-IP Data Center Firewall Solution – SlideShare Presentation High Performance Firewall for Data Centers – Solution Profile The New Data Center Firewall Paradigm – White Paper Vulnerability Assessment with Application Security – White Paper Challenging the Firewall Data Center Dogma Technorati Tags: F5, big-ip, virtualization, cloud computing, Pete Silva, security, icsa, iApp, compliance, network firewall, internet, TMOS, big-ip, vCMPComplying 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 psCloudFucius Wonders: Can Cloud, Confidentiality and The Constitution Coexist?
This question has been puzzling a few folks of late, not just CloudFucius. The Judicial/legal side of the internet seems to have gotten some attention lately even though courts have been trying to make sense and catch up with technology for some time, probably since the Electronic Communications Privacy Act of 1986. There are many issues involved here but a couple stand out for CloudFucius. First, there is the ‘Privacy vs. Convenience’ dilemma. Many love and often need the GPS Navigators whether it be a permanent unit in the vehicle or right from our handheld device to get where we need to go. These services are most beneficial when searching for a destination but it is also a ‘tracking bug’ in that, it records every movement we make. This has certainly been beneficial in many industries like trucking, delivery, automotive, retail and many others, even with some legal issues. It has helped locate people during emergencies and disasters. It has also helped in geo-tagging photographs. But, we do give up a lot of privacy, secrecy and confidentiality when using many of the technologies designed to make our lives ‘easier.’ Americans have a rather tortured relationship with privacy. They often say one thing ("Privacy is important to me") but do another ("Sure, thanks for the coupon, here's my Social Security Number") noted Lee Rainie, head of the Pew Internet and American Life Project. From: The Constitutional issues of cloud computing You might not want anyone knowing where you are going but by simply using a navigation system to get to your undisclosed location, someone can track you down. Often, you don’t even need to be in navigation mode to be tracked – just having GPS enabled can leave breadcrumbs. Don’t forget, even the most miniscule trips to the gas station can still contain valuable data….to someone. How do you know if your milk runs to the 7-Eleven aren’t being gathered and analyzed? At the same, where is that data stored, who has access and how is it being used? I use GPS when I need it and I’m not suggesting dumping it, just wondering. Found a story where Mobile Coupons are being offered to your phone. Depending on your GPS location, they can send you a coupon for a nearby merchant along with this one about Location-Based strategies. Second, is the Fourth Amendment in the digital age. In the United States, the 4th Amendment protects against unreasonable searches and seizures. Law enforcement needs to convince a judge that a serious crime has/is occurring to obtain a warrant prior to taking evidence from a physical location, like your home. It focuses on physical possessions and space. For instance, if you are committing crimes, you can place your devious plans in a safe hidden in your bedroom and law enforcement needs to present a search warrant before searching your home for such documents. But what happens if you decide to store your ‘Get rich quick scheme’ planning document in the cloud? Are you still protected? Can you expect certain procedures to be followed before that document is accessed? The Computer Crime & Intellectual Property Section of the US Dept of Justice site states: To determine whether an individual has a reasonable expectation of privacy in information stored in a computer, it helps to treat the computer like a closed container such as a briefcase or file cabinet. The Fourth Amendment generally prohibits law enforcement from accessing and viewing information stored in a computer if it would be prohibited from opening a closed container and examining its contents in the same situation….Although courts have generally agreed that electronic storage devices can be analogized to closed containers, they have reached differing conclusions about whether a computer or other storage device should be classified as a single closed container or whether each individual file stored within a computer or storage device should be treated as a separate closed container. But, you might lose that Fourth Amendment right when you give control to a third party, such as a cloud provider. Imagine you wrote a play about terrorism and used a cloud service to store your document. Maybe there were some ‘surveillance’ keywords or triggers used as character lines. Maybe there is scene at a transportation hub (train, airport, etc) and characters themselves say things that could be taken as domestic threats – out of context of course. You should have some expectation that your literary work is kept just as safe/secure while in the cloud as it is on your powered down hard drive or stack of papers on your desk. And we haven’t even touched on compliance, records retention, computer forensics, data recovery and many other litigating issues. The cases continue to play out and this blog entry only covers a couple of the challenges associated with Cloud Computing and the Law, but CloudFucius will keep an eye on it for ya.

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 the last entry is Maintain an Information Security Policy which includes PCI Requirement 12. 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, Part 4: Complying with PCI DSS–Part 4: Implement Strong Access Control Measures and Part 5: Complying with PCI DSS–Part 5: Regularly Monitor and Test Networks. Requirement 12: Maintain a policy that addresses information security for all personnel. PCI DDS Quick Reference Guide description: A strong security policy sets the security tone for an entire organization’, and it informs employees of their expected duties related to security. All employees should be aware of the sensitivity of cardholder data and their responsibilities for protecting it. Solution: The spirit of this requirement is to ensure the adoption of a Corporate Information Security Policy (CISP). Although policy-based, F5 solutions don’t, by themselves, meet this requirement in context. F5 products facilitate adherence to the CISP, but they do not actually comprise a CISP. That said, F5 products can help organizations roll out business policies and security policies together. Applications needn’t be built and deployed in a vacuum; F5 technologies can be implemented in conjunction with corporate policies that address information security. Since the inception of the PCI DSS, organizations have been laboring to understand, implement, and comply with its guidelines. Often, achieving that goal requires deploying and managing several different types of devices. The BIG-IP platform enables organizations to understand inherent threats and take specific measures to protect their web application infrastructures and to satisfy many PCI DSS requirements. psComplying 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 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 psComplying 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 ps
