SIGMA

Sigma is an open signature format that allows you to define log events. You can apply Sigma rules to any log file format to augment its data with relevant security information. As the Sigma project states, “Sigma is for log files what Snort is for network traffic and YARA is for files.”

logz.io ELK Stack

The ELK stack can be a great building block for your SIEM system. However, the recent shift of Logstash and Kibana to SSPL licenses makes two of its core components technically not open-source. Consequentially, this switch in licensing embeds contributions made by the public and you in proprietary products. The other disadvantages of the ELK stack include a lack of built-in security rules, reporting, or alerting capabilities. The ELK stack is also famous for being resource and operations-heavy, meaning that you might end up spending a lot of time and money in building and managing the perfect ELK stack implementation for your company.
