Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS) [4] created in 1998 by Martin Roesch, founder and former CTO of Sourcefire. [ 5 ] [ 6 ] Snort is now developed by Cisco , which purchased Sourcefire in 2013.
Suricata is an open-source based intrusion detection system (IDS) and intrusion prevention system (IPS). It was developed by the Open Information Security Foundation (OISF). A beta version was released in December 2009, with the first standard release following in July 2010. [4] [5]
The most common classifications are network intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS). A system that monitors important operating system files is an example of an HIDS, while a system that analyzes incoming network traffic is an example of an NIDS. It is also possible to classify IDS by detection approach.
An attacker can exhaust the IDS's CPU resources in a number of ways. For example, signature-based intrusion detection systems use pattern matching algorithms to match incoming packets against signatures of known attacks. Naturally, some signatures are more computational expensive to match against than others.
A host-based IDS is capable of monitoring all or parts of the dynamic behavior and the state of a computer system, based on how it is configured.Besides such activities as dynamically inspecting network packets targeted at this specific host (optional component with most software solutions commercially available), a HIDS might detect which program accesses what resources and discover that, for ...
The LAMP bundle can be combined with many other free and open-source software packages, including: netsniff-ng for security testing and hardening; Snort, an intrusion detection (IDS) and intrusion prevention (IPS) system; RRDtool for diagrams; Nagios, Collectd or Cacti, for monitoring.

Network-based anomalous intrusion detection systems often provide a second line of defense to detect anomalous traffic at the physical and network layers after it has passed through a firewall or other security appliance on the border of a network. Host-based anomalous intrusion detection systems are one of the last layers of defense and reside ...
