Packet Crafting for Firewall & IDS Audits (Part 2 of 2)
Introduction This is the second of a two-part article series that discusses various methods of testing the integrity of your firewall and IDS, using low-level TCP/IP packet crafting tools and techniques. Part one showed several examples that tested a firewall (port 80 TCP, and port 53, UDP) using tools like hping and tcpdump . We will now continue the discussion with a third test of the firewall, using the same tools as noted above, and then move on to test your IDS signatures and detection ability. Note that the focus here is on a Linux environment, but the process is similar with other Unix-like firewall/IDS environments as well.
Optimizing NIDS Performance
Introduction Network intrusion detection systems (NIDSs) face some of the most gruelling challenges of any security product. Not only is the bandwidth these devices monitor increasing, so are the amount of attacks they must guard against. The combination of these two factors could overwhelm a NIDS, causing it to drop packets. To help the NIDS keep up with the demands of today’s networks, and the wide variety of threats that besiege them, there are a number of things that the NIDS administrator can do to improve the performance of their NIDS. This article will examine some of those options.
