Suricata alternatives

Zeek helps to perform security monitoring by looking into the network's activity. It can find suspicious data streams. Based on the data, it alert, react, and integrate with other tools.

This tool helps with automating the installation of several components like Bro IDS, Elasticsearch, Logstash, Kibana (ELK stack), and Critical Stack. Saving time on installation and configuration is its primary purpose.

Besides intrusion detection, Snort has the capabilities to prevent attacks. By taking a particular action based on traffic patterns, it can become an intrusion prevention system (IPS).

DejaVu is an open source deception framework which can be used to deploy and administer decoys or canaries across a network infrastructure. Defenders can use deception as a technique to learn quickly about possible attackers on the network and take actions.

CHIRON is a tool to provide network analytics based on the ELK stack. It is combined with Machine Learning threat detection using the Aktaion framework. Typical usage of the tool is home use and get the visibility of home internet devices. By leveraging the Aktaion framework, it helps with detection threats like ransomware, phishing, or other malicious traffic.

Moloch comes with a web interface that allows for easy browsing of pcap data (packet capture). It can also search in the data or export it. Besides pcap, the JSON format is supported, so data can be easily consumed in other tools (like Wireshark).

MISP collects, stores, and distributes security indicators and discovered threats. This makes the platform useful for those involved with security incidents and malware research. Users benefit from having a well-tested platform to structure the vast number of data points available when it comes to security threats. The tooling allows interaction with other tools, like security incident and event management (SIEM) and intrusion detection systems (IDS).

Chiron is a security assessment framework for IPv6. It provides several modules including an IPv6 scanner, IPv6 Local Link, IPv4-to-IPv6 proxy, IPv6 attack module, and IPv6 proxy. These modules help to perform an assessment, like a penetration test.

The tool uses IPv6 extension headers to create a headers chain. This may allow evading security devices like IDS, IPS, and firewalls. Due to the flexibility of the framework, the tool can also be used to perform fuzzing of the IPv6 stack of a device.

OSSEC uses a centralized, cross-platform architecture allowing multiple systems to be monitored and managed.

Highlights:
The OSSEC project was acquired by Third Brigade, Inc in June 2008. This included the copyrights owned by Daniel Cid, its project leader. They promised to continue the development, keep it open source, and extend commercial support and training to the community.

Trend Micro acquired Third Brigade in May 2009. This included the OSSEC project. Trend Micro promised to keep the software open source and free.

Samhain is a host-based intrusion detection system (HIDS). It provides file integrity checking and log file monitoring/analysis. Additional features are rootkit detection, port monitoring, detection of rogue SUID executables, and the detection of hidden processes.

Samhain is typically deployed as a standalone application, although it supports centralized logging. This makes it ideal for environments with multiple systems.

Samhain is open source software and written by Rainer Wichmann.

The goal of the GRR tooling is to support digital forensics and investigations. By using a fast and scalable model, analysts can quickly perform their analysis. One of the main features is the ability to search for particular information or details. This process is called hunting.

The main purpose to use HELK is to do analytic research on data, which are typically the events coming from your systems. Suspicious events could be discovered by doing so-called threat hunting. It may give additional insights about the existing infrastructure and required security defenses.

Rastrea2r is a threat hunting utility for indicators of compromise (IOC). It is named after the Spanish word rastreador, which means hunter. This multi-platform open source tool helps incident responders and SOC analysts to triage suspected systems. The hunt for IOCs can be achieved in just a matter of a few minutes.
