Analysis of Firewall Policy Rules Using Data Mining Techniques
White Paper These firewall rules are mostly custom-designed and hand-written thus in constant need for tuning and validation, due to the dynamic nature of the traffic characteristics, ever-changing network environment and its market demands. [16 Apr 2008]
How closely are you monitoring?

Storm botnet 'services' for hire?
News Stewart said the good news is security researchers can now distinguish encrypted Storm traffic from legitimate peer-to-peer traffic, making it easier for network administrators to detect Storm nodes on networks where firewall policies normally... [17 Oct 2007]
Opportunistic Measurement: Extracting Insight From Spurious Traffic
White Paper In particular, much of the Internet's modern growth, in both size and complexity, is "Protected" by NAT and firewall technologies that preclude the use of traditional measurement techniques. This paper argues for a new approach to illuminate these... [09 Jun 2007]
Do you know what's happening on your network?
Comment And the place to start is increasingly within the firewall. Norton explained this is so the laptop can be thoroughly tested for patches, security updates and vulnerabilities - as well as any infections it may have picked up outside the firewall... [28 Mar 2007]
The biggest VoIP security threats - and how to stop them
