Enterprise SIEMs on average have detection coverage for only 21% of ATT&CK techniques (2025 CardinalOps report), with 13% of existing rules being non-functional due to misconfigured data sources. Systematic coverage mapping identifies gaps, prioritizes rule development, and tracks detection maturity over time. ATT&CK v18.1 (December 2025) is the latest version.\n\n\n## When to Use\n\n- When deploying or configuring implementing mitre attack coverage mapping capabilities in your environment\n- When establishing security controls aligned to compliance requirements\n- When building or improving security architecture for this domain\n- When conducting security assessments that require this implementation\n\n## Prerequisites\n\n- Access to MITRE ATT&CK Navigator (https://mitre-attack.github.io/attack-navigator/)\n- Inventory of all active SIEM detection rules\n- MITRE ATT&CK technique mapping for each detection rule\n- Data source inventory (which log sources are ingested)\n- Understanding of adversary threat profiles relevant to your industry\n\n## Coverage Mapping Process\n\n### Step 1: Export Current Detection Rules\n\n```spl\n# Splunk ES - Export all active correlation searches with MITRE mappings\n| rest /services/saved/searches\n| search disabled=0 action.correlationsearch.enabled=1\n| table title, search, action.notable.param.security_domain,\n    action.notable.param.severity, action.correlationsearch.annotations\n| eval mitre_techniques=mvfilter(match('action.correlationsearch.annotations', \"mitre_attack\"))\n```\n\n```kql\n// Microsoft Sentinel - Export analytics rules with MITRE mapping\nSecurityAlert\n| summarize count() by AlertName, ProductName\n| join kind=inner (\n    resources\n    | where type == \"microsoft.securityinsights/alertrules\"\n    | extend tactics = properties.tactics\n) on $left.AlertName == $right.name\n```\n\n### Step 2: Build the Coverage Matrix\n\n#### ATT&CK Navigator Layer Format\n\n```json\n{\n    \"name\": \"SOC Detection Coverage -

Based on MITRE Top Techniques report\n  - Frequency in your industry's threat landscape\n  - Observed in recent incidents/breaches\n\nImpact (0-10):\n  - Damage potential if technique succeeds\n  - Difficulty of recovery\n  - Data sensitivity at risk\n\nFeasibility (0-10):\n  - Data source availability\n  - Rule complexity\n  - Engineering effort required\n```\n\n#### Top Priority Techniques to Cover (2025)\n\n| Technique | ID | Prevalence | Typical Gap Reason |\n|---|---|---|---|\n| Command and Scripting Interpreter | T1059 | Very High | Requires script block logging |\n| Phishing | T1566 | Very High | Email gateway integration |\n| Valid Accounts | T1078 | High | Baseline behavior needed |\n| Process Injection | T1055 | High | Requires Sysmon or EDR |\n| Lateral Movement (RDP/SMB) | T1021 | High | Network segmentation visibility |\n| Scheduled Task/Job | T1053 | High | Event log collection |\n| Data Encrypted for Impact | T1486 | High | File system monitoring |\n| Ingress Tool Transfer | T1105 | Medium | Network traffic analysis |\n\n### Step 5: Build Detection Roadmap\n\n```\nQuarter 1: Close Critical Gaps (Score 0, High Prevalence)\n  Week 1-2: Enable missing data sources\n  Week 3-4: Build and test rules for top 5 gap techniques\n  Week 5-8: Validate with adversary emulation\n  Week 9-12: Tune and operationalize\n\nQuarter 2: Improve Partial Coverage (Score 25-50)\n  -
