Apple has admitted that is has at LEAST three serious design weaknesses in it’s new application based firewall being rolled out with Mac OS X ‘Leopard’.
It comes (somewhat oddly) only 24 hours after a Mac OS X security update that fixed 41 OS X and Safari security vulnerabilities.

The tool consists of two perl scripts, a packet injector (ftest) and the listening sniffer (ftestd). The first script injects custom packets, defined in ftest.conf, with a signature in the data part while the sniffer listens for [...]

So instead, they target the end user, home bankers, [...]

This is an excellent article you might find useful covering the use of the capture command in Cisco PIX firewalls.

A vital tool to use when troubleshooting computer networking problems and monitoring computer networks is a packet sniffer. That being said, one of the best methods to use when troubleshooting connection problems or monitoring suspicious network [...]

Today sees the launch of “OneCare”, Microsofts “secrity solution”. Combining firewall, anti-virus and anti-spyware in to one handy package…. but would you trust it?
