Sigma Custom Rules

AlphaSOC enables customers to craft custom detection rules using the Sigma language, a flexible and open-source standard for defining threat detection logic. These custom rules are submitted to the AlphaSOC team for a thorough Quality Assurance (QA) process, ensuring they are reliable and effective before deployment into the Analytics Engine. This streamlined approach allows customers to easily adapt detections to their unique security needs.

Crafting and Deploying Custom Rules​

With Sigma’s straightforward YAML-based syntax, security teams can write rules to detect specific threats or behaviors relevant to their environment. Once submitted, the AlphaSOC team reviews each rule for accuracy, performance, and compatibility. After passing QA, the rules are seamlessly integrated into the analytics engine, empowering customers to:

  • Address organization-specific risks, such as insider threats or industry-targeted attacks.
  • Enhance detection capabilities beyond standard rulesets.
  • Align security measures with internal policies or compliance requirements.

This process provides a simple yet powerful way to customize threat detection without compromising quality or operational efficiency.

Expanding Sigma: Advanced Detection Techniques​

AlphaSOC is currently enhancing the Sigma language to support more sophisticated detection methods. These upcoming expansions will allow customers to:

  • Incorporate Anomaly Detection: Identify unusual patterns, such as abnormal user behavior or network activity, using behavioral analytics.
  • Utilize Threat Intelligence Enrichment: Strengthen rules with real-time data, like known malicious IPs or domains, for greater context and precision.

These advancements will enable security teams to combine traditional rule-based detection with cutting-edge techniques, creating a more robust and adaptive security strategy.

Why It Matters​

Custom Sigma rules give AlphaSOC customers the flexibility to tailor detections to their specific threat landscape, backed by expert QA and deployment support. With future Sigma enhancements, organizations can leverage advanced analytics and intelligence, ensuring their defenses evolve alongside emerging threats.
