Intrusion Detection System for added security
Intrusion Detection System (IDS) are a very common term for anyone who has ever been involved in network protection of any sort. These systems are basically those that analyze various activities on the network to attempt to spot likely attacks on the network. There are different IDS available in the market and they have different ways of working. These systems are placed at strategic locations in the network so that they can scan outbound and inbound traffic and analyze them. They check the network according to a set of rules and regulations in order to spot potential attacks on the internet.
IDS are host based and they run on the individual hosts in the network. If needed they may even use other techniques like hash comparing of other operating systems so that they can detect changes in some key functional areas like key system files, access control lists or other host systems.
