Network intrusion detection software and systems are now essential for network security. Network-based Intrusion Detection System (NIDS) – this system will examine the traffic on your network.Host-based Intrusion Detection System (HIDS) – this system will examine events on a computer on your network rather than the traffic that passes around the system.There are two main types of intrusion detection systems (both are explained in more detail later in this guide): Fail2Ban Lightweight host-based intrusion detection software system for Unix, Linux, and Mac OS.Samhain Straightforward host-based intrusion detection system for Unix, Linux, and Mac OS.OpenWIPS-NG Wireless NIDS and intrusion prevention system from the makers of Aircrack-NG.AIDE The Advanced Intrusion Detection Environment is a HIDS for Unix, Linux, and Mac OS.Security Onion Network monitoring and security tool made up of elements pulled in from other free tools.Sagan Log analysis tool that can integrate reports generated on snort data, so it is a HIDS with a bit of NIDS.Zeek Network monitor and network-based intrusion prevention system.Suricata Network-based intrusion detection system software that operates at the application layer for greater visibility.
OSSEC Excellent host-based intrusion detection system that is free to use.Snort Provided by Cisco Systems and free to use, leading network-based intrusion detection system software.ManageEngine Log360 (FREE TRIAL) This SIEM package uses UEBA to establish a baseline of normal activity and then looks for deviations from that norm.ManageEngine EventLog Analyzer (FREE TRIAL) A log file analyzer that searches for evidence of intrusion.An essential tool for improving security, responding to events and achieving compliance. SEM is also an intrusion prevention system, shipping with over 700 rules to shut down malicious activity. It manages data collected by Snort, including real-time data. SolarWinds Security Event Manager EDITOR’S CHOICE Analyzes logs from Windows, Unix, Linux, and Mac OS systems.
Here’s our list of the Best Intrusion Detection System Software and Tools: Detection of anomalous activity and reporting it to the network administrator is the primary function however, some IDS software can take action based on rules when malicious activity is detected, for example blocking certain incoming traffic. What is an Intrusion Detection System (IDS)?Īn Intrusion Detection System ( IDS) monitors network traffic for unusual or suspicious activity and sends an alert to the administrator.
