MITRE ATT&CK coverage mapping gives SOC teams a structured, adversary-centric lens to evaluate detection capabilities. 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.
MITRE ATT&CK technique mapping for each detection rule
Data source inventory (which log sources are ingested)
Understanding of adversary threat profiles relevant to your industry
Coverage Mapping Process
Scope and authorize — confirm written authorization and define target boundaries
Reconnaissance — enumerate targets, services, and potential attack surfaces
Exploitation — attempt exploitation of identified vulnerabilities within scope
Post-exploitation — document access level, lateral movement, and data exposure
Report and remediate — compile findings with reproduction steps and fix recommendations
Step 1: Export Current Detection Rules
# Splunk ES - Export all active correlation searches with MITRE mappings
| rest /services/saved/searches
| search disabled=0 action.correlationsearch.enabled=1
| table title, search, action.notable.param.security_domain,
action.notable.param.severity, action.correlationsearch.annotations
| eval mitre_techniques=mvfilter(match('action.correlationsearch.annotations', "mitre_attack"))
// Microsoft Sentinel - Export analytics rules with MITRE mapping
SecurityAlert
| summarize count() by AlertName, ProductName
| join kind=inner (
resources
| where type == "microsoft.securityinsights/alertrules"
| extend tactics = properties.tactics
) on $left.AlertName == $right.name
Step 2: Build the Coverage Matrix
ATT&CK Navigator Layer Format
{"name":"SOC Detection Coverage - 2025","versions":{"attack":"16","navigator":"5.1","layer":"4.5"},"domain":"enterprise-attack","description":"Current detection coverage mapping","techniques":[{"techniqueID":"T1110","tactic":"credential-access","color":"#00ff00","comment":"2 active rules - Brute Force detection via EventCode 4625","score":75,"metadata":[{"name":"rule_count","value":"2"},{"name":"data_sources","value":"Windows Security Log, Linux Auth"},{"name":"last_validated","value":"2025-01-15"}]},{"techniqueID":"T1059.001","tactic":"execution","color":"#00ff00","comment":"3 rules - PowerShell Script Block Logging","score":85},{"techniqueID":"T1055","tactic":"defense-evasion","color":"#ff0000","comment":"NO DETECTION - Requires Sysmon EventCode 8/10","score":0}],"gradient":{"colors":["#ff0000","#ffff00","#00ff00"],"minValue":0,"maxValue":100}}
Step 3: Score Each Technique
Score
Color
Meaning
Criteria
0
Red
No Detection
No rules, missing data sources
25
Orange
Minimal
Rule exists but not validated/tested
50
Yellow

Multiple validated rules, tested with emulation
Scoring Criteria Detail
Score = Data_Source_Score (0-25) + Rule_Quality_Score (0-25) +
Validation_Score (0-25) + Enrichment_Score (0-25)
Data_Source_Score:
25: All required data sources ingested and parsed
15: Primary data source available
5: Partial data source coverage
0: Required data sources not available
Rule_Quality_Score:
25: Rule uses CIM-compliant queries with proper thresholds
15: Rule works but may generate false positives
5: Basic rule with no tuning
0: No detection rule
Validation_Score:
25: Validated with adversary emulation (Atomic Red Team)
15: Tested with synthetic data
5: Logic reviewed but not tested
0: Not validated
Enrichment_Score:
25: Context-rich with asset, identity, and TI enrichment
15: Basic enrichment (asset lookup)
5: No enrichment
0: N/A (no rule)
Step 4: Identify Priority Gaps
Gap Prioritization Framework
Priority = Technique_Prevalence x Impact x Feasibility
Technique_Prevalence (0-10):
- Based on MITRE Top Techniques report
- Frequency in your industry's threat landscape
- Observed in recent incidents/breaches
Impact (0-10):
- Damage potential if technique succeeds
- Difficulty of recovery
- Data sensitivity at risk
Feasibility (0-10):
- Data source availability
- Rule complexity
- Engineering effort required
