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 Friday: Goodbye Defense in Depth. Hello Defense in Breadth.
#adcfw #infosec F5 is changing the game on security by unifying it at the application and service delivery layer. Over the past few years we’ve seen firewalls fail repeatedly. We’ve seen business disrupted, security thwarted, and reputations damaged by the failure of the very devices meant to prevent such catastrophes from happening. These failures have been caused by a change in tactics from invaders who seek no longer to find away through or over the walls, but who simply batter it down instead. A combination of traditional attacks – network-layer – and modern attacks – application-layer – have become a force to be reckoned with; one that traditional stateful firewalls are often not equipped to handle. Encrypted traffic flowing into and out of the data center often bypasses security solutions entirely, leaving another potential source of a breach unaddressed. And performance is being impeded by the increasing number of devices that must “crack the packet” as it were and examine it, often times duplicating functionality with varying degrees of success. This is problematic because the resolution to this issue can be as disconcerting as the problem itself: disable security. Seriously. Security functions have been disabled, intentionally, in the name of performance. IT security personnel within large corporations are shutting off critical functionality in security applications to meet network performance demands for business applications. SURVEY: SECURITY SACRIFICED FOR NETWORK PERFORMANCE What the company [NSS Labs] found would likely startle any existing or potential customers: three of the six firewalls failed to stay operational when subjected to stability tests, five out of six didn't handle what is known as the "Sneak ACK attack," that would enable attackers to side-step the firewall itself. Finally, according to NSS Labs, the performance claims presented in the vendor datasheets "are generally grossly overstated." Independent lab tests find firewalls fall down on the job Add in the complexity from the sheer number of devices required to implement all the different layers of security needed, which increases costs while impairing performance, and you’ve got a broken model in need of repair. This is a failure of the defense in depth strategy; the layered, multi-device (silo) approach to operational security. Most importantly, it’s one that’s failing to withstand attacks. What we need is defense in breadth – the height of the stack –to assure availability and security using a more intelligent, unified security strategy. DEFENSE in BREADTH While it’s really not as catchy as “defense in the depth” the concept behind the admittedly awkward sounding phrase is sound: to assure availability and security simultaneously requires a strong security strategy from the bottom to the top of the networking stack, i.e. the application layer. The ability of the F5 BIG-IP platform to provide security up and down the stack has existed for many years, and its capabilities to detect, prevent, and withstand concerted attacks has been appreciated by its customers (quietly) for some time. While basic firewalling functions have been a part of BIG-IP for years, there are certain capabilities required of a firewall – specifically an ICSA certified firewall – that it didn’t have. So we decided to do something about that. The result is the ICSA certification of the BIG-IP platform as a network firewall. Combined with its existing ICSA certification for web application firewall (BIG-IP Application Security Manager) and SSL-TLS VPN 3.0 (BIG-IP Edge Gateway), the BIG-IP platform now supports a full-spectrum security solution in a single, unified system. What is unique about F5’s approach is that the security capabilities noted above can be deployed on BIG-IP Application Delivery Controllers (ADCs)—best known for providing industry-leading intelligent traffic management and optimization capabilities. This firewall solution is part of F5’s comprehensive security architecture that enables customers to apply a unified security strategy. For the first time in the industry, organizations can secure their networks, data, protocols, applications, and users on a single, flexible, and extensible platform: BIG-IP. Combining network-firewall services with the ability to plug the hole in modern security implementations (the application layer) with a platform-based solution provides the opportunity to consolidate security services and leverage a shared infrastructure platform resulting in a more comprehensive, strategic deployment that is not only more secure, but more cost effective.

#devops #v11 #iapp Let’s spend some time talking about how iApp templates aren’t just for deploying and managing applications. Huh? The value of iApp templates extends far beyond applications. Remember, a template is used to describe the user interface and how the system will act on information gathered from the user, so practically any service, operational task or application can be delivered through this method. For instance, BIG-IPs are commonly used to provide high availability, scalability or proxy services for mission critical network services, such as LDAP, Radius, DNS, Diameter and SIP. The configurations are all supported by F5-provided iApp templates allowing administrators to deploy, manage and monitor them, just as easily as an application. F5-provided iApp templates have also been extended to regulatory standards such as NIST and ICSA. These iApp templates make it easy for users to configure and ensure compliance by setting logging, authentication policies, etc. iApp templates are also very helpful to manage operational tasks. Jason Rahm posted an iApp template example for scheduling configuration backups. Michael Earnhart (PME – with mean ice cream making skills. Vodka-blueberry ice cream anyone?!?!?) wrote an article and example about how users could create an iApp template to build and manage their iRules! (More on that next post) Pretty amazing technology. But, what about you? What would you do in an iApp?
