The importance of the network security problems
comes into prominence by the growth of the Internet.
This article introduces the basics of the host security
problem, reviews the most important intrusion detection
methods, and finally proposes a novel solution.
Different kinds of security software utilizing the
network have been described (Snort, 2006). The novelty
of the proposed method is that its clients running in
each host create a peer-to-peer (P2P) overlay network.
Organization is automatic; it requires no user interaction.
This network model ensures stability, which is important
for quick and reliable communication between nodes.
Its main idea is that the network that is the easiest way
to attack the networked computers is utilized in the
novel approach in order to improve the efficiency of the
protection. By this build-up the system remains useful
over the unstable network. The first implementation of
the proposed method has proved its ability to protect
operating systems of networked hosts.
