Implementing SIEM Use Cases for Detection

When to Use

Use this skill when:

• SOC teams need to build or expand their SIEM detection library from scratch
• Threat assessments identify ATT&CK technique gaps requiring new detection rules
• Detection engineers need a structured process for use case design, testing, and deployment
• Compliance requirements mandate specific detection capabilities (PCI DSS, HIPAA, SOX)

Do not use for ad-hoc hunting queries — use cases are formalized, tested, and maintained detection rules, not exploratory searches.

Prerequisites

• SIEM platform (Splunk ES, Elastic Security, or Microsoft Sentinel) with production data
• ATT&CK Navigator for coverage gap analysis
• Log sources normalized to CIM/ECS field standards
• Use case documentation framework (wiki, Git repo, or detection engineering platform)
• Testing environment with attack simulation tools (Atomic Red Team, MITRE Caldera)
