Is the Intrusion Detection System, IDS, dead?
There have been quite a few people, and some questionable research groups, who have claimed the Intrusion Detection System (IDS) to be dead. No longer a relevant technology and all that. Well I for one would disagree with that statement. While the IDS is not the end all be all of network security it is still a vital piece of it. The main problem with them is that the people who administer them often don’t have the requisite knowledge. They would be hard pressed to differentiate between and ICMP echo request and an ICMP echo reply. Much like any piece of network security technology, it is only as good as the person administering it.
