You can also write your own policies. Zeek is a very well-established network-based intrusion detection system.
This free tool is better known by its old name: Bro. The tool changed its name to Zeek in Zeek is an open-source project that is supported financially by some very big names, including the Mozilla Foundation and the International Computer Science Institute.
So, Zeek captures data packets and then stores them in files. This makes it an application-level NIDS. The packet files are analyzed by the Zeek Event Engine. This is a semantic analyzer that looks for unusual patterns that break out of standard activity behavior.
The detection techniques used by the analyzer are therefore anomaly-based. However, the analyzer also does a sweep for well-known malicious intruder behavior, so it deploys signature-based analysis as well. The system includes a scripting language that enables technicians to write their own capture routines and anomaly scans. This technical aspect might put many people off using the system. However, the monitor has a large following, so there is a big user community out there to advise newbies.
Kibana is probably the most regularly used interface for Zeek. This is a fee-based system that applies application layer analysis , so it will detect signatures that are spread across data packets. There is also a file extraction facility that enables the analysis of virus-infected files. Suricata has a built-in scripting module that enables you to combine rules and get a more precise detection profile.
This IDS uses both signature-based and anomaly-based detection methods. VRT rules files written for Snort can also be imported into Surcata because this intrusion detection system is compatible with the Snort platform. However, the Suricata GUI is very sophisticated and includes graphical representations of data, so you might not need to use any other tool to view and analyze data. Sagan is a free host-based intrusion detection system that can be installed on Unix , Linux , and Mac OS.
Sagan is also compatible with other Snort-type systems, such as Snorby , BASE , Squil , and Anaval , which could all provide a front end for data analysis. Sagan is a log analysis tool and it needs to be used in conjunction with other data gathering systems in order to create a full intrusion detection system.
The utility includes an IP locator , so you can trace the sources of suspicious activities to a location. It can also group together the activities of suspicious IP addresses to identify team or distributed attacks. The analysis module works with both signature and anomaly detection methodologies. Sagan can automatically execute scripts to lock down the network when it detects specific events.
It performs these prevention tasks through interaction with firewall tables. So, this is an intrusion prevention system. It was written to run specifically on Ubuntu. Host-based analysis checks for file changes and network analysis is conducted by a packet sniffer , which can display passing data on a screen and also write to a file. The analysis engine of Security Onion is complicated because it combines the procedures of so many different tools.
It includes device status monitoring as well as network traffic analysis. There are both signature-based and anomaly-based alert rules included in this system. The interface of Kibana provides the dashboard for Security Onion and it includes graphs and charts to ease data analysis. This IDS focuses on rootkit detection and file signature comparisons. The data gathering module populates a database of characteristics that are gleaned from log files.
This database is a system status snapshot and any changes in device configuration trigger alerts. Those changes can be canceled by reference to the database or the database can be updated to reflect authorized configuration alterations. System activity checks are performed on-demand and not continuously, but it can be scheduled as a cron job. The rules base of AIDE uses both signature-based and anomaly-based monitoring methods. In fact, it integrates Aircrack-NG as its wireless packet sniffer.
Aircrack-NG is a well-known hacker tool, so this association may make you a little wary. This is a free utility that includes three elements:. The sensor is also a transmitter , so it can implement intrusion prevention actions and cripple unwanted transmissions.
The server performs analysis and also launches intervention policies to block detected intrusions. The interface module displays events and alerts to the systems administrator. This is also where settings can be tweaked and defensive actions can be adjusted or overridden.
It uses agents running at different points on the network, which report back to a central analysis module. Each agent performs file integrity checking , log file monitoring , and port monitoring. The processes look for rootkit viruses , rogue SUIDs user access rights , and hidden processes.
Network communication between agents and the console is protected by encryption. Connections for the delivery of log file data include authentication requirements, which prevent intruders from hijacking or replacing the monitoring process. You will need to keep backups of your configuration files and user identities in order to take action to resolve the problems that the Samhain monitor reveals.
Central log files and configuration backups are signed with a PGP key to prevent tampering by intruders. These blocks usually only last a few minutes, but that can be enough to disrupt a standard automated brute-force password-cracking scenario. Alert situations include excessive failed login attempts.
A problem with Fail2Ban is that it focuses on repeated actions from one address.
