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]
whitepaper This white paper talks about defensive strategies to be applied while implementing firewalls, how to classify firewalls, screening router (Packet Filters), proxy server gateways, inspection techniques and firewall policies.
[26 Jun 2007]
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...

whitepaper This white paper discusses how HTTPS filtering (SSL scanning) provides organisations with the means to counter these threats by fully extending their existing Internet usage policies to HTTPS traffic, and thereby proactively closing that last...
[06 Feb 2007]
whitepaper Using a firewall, a person can separate a network or LAN into multiple components to create segmented network architecture. The firewall blocks data that is not destined for a particular segment, and might block all protocol ports except those that...
