Elastic Security simplifies customization of prebuilt SIEM detection rules

Elastic Security has made it easier to customize and update prebuilt detection rules, streamlining detection engineering workflows and enabling greater use case coverage. Elastic Security Labs provides over 1,300 expert-written detection rules that map to tactics, techniques, and procedures across the MITRE ATT&CK framework. These rules are actively maintained and updated biweekly to help stay ahead of evolving threats. Security teams can tailor these prebuilt detections to meet specific needs, and with the latest releases, detection engineers can apply Elastic-provided rule updates without losing custom modifications. The new features allow editing of prebuilt rules individually or in bulk, and the ability to compare incoming changes to the current version of the rule. Rule updates reduce false positives and increase alert fidelity, and the improved rule update experience enables detection engineers to focus on updating priority rules first. The new improvements significantly reduce and simplify maintenance of detections, empowering security teams to reap the benefits of prebuilt rules optimized for their environment and use cases. This capability is generally available in Elastic Security 8.18 and 9.0 versions via the Elastic Security Enterprise subscription tier for self-managed and cloud deployments and the Security Analytics Complete tier on Elastic Cloud Serverless. The biweekly rule releases provide new and updated rules and timelines, available right in Elastic Security, and in 2024 alone, over 2,420 updates were issued to the rule library.
