Anti-Malware Coverage
Description
Anti-malware mechanisms must be deployed on all system components commonly affected by malicious software, kept current, and actively running.
⚠️ Risk Impact
Endpoint malware is a vector for credential theft + lateral movement into the CDE. Coverage gaps create entry points; outdated definitions miss modern threats.
🔍 How EchelonGraph Detects This
EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as high-severity findings with remediation guidance.
🔧 Remediation
Deploy modern EDR on workstations + servers in CDE. Maintain coverage tracking. Tune for high-confidence detection + automated response. Integrate with SIEM.
💀 Real-World Attack Scenario
A point-of-sale server had outdated antivirus signatures (3 months old). A new variant of RAMscraper malware infected the system + scraped card data from RAM during transactions. Detection only when card brands flagged coincidental fraud. Loss: $4.5M + $2.1M settlement.
💰 Cost of Non-Compliance
PCI 5.2 violations: $5K-$100K/month. Malware-related CDE breach: avg $5.5M.
📋 Audit Questions
- 1.What EDR is deployed in CDE?
- 2.Coverage percentage?
- 3.Signature/threat-feed update cadence?
- 4.Active response capability?
🎯 MITRE ATT&CK Mapping
⚡ Common Pitfalls
- ⛔Antivirus deployed but signature updates fail silently
- ⛔EDR exclusions list grows without review
- ⛔Coverage gaps on POS / specialized terminals
📈 Business Value
Modern EDR is required for PCI + prevents the highest-frequency CDE attack vectors.
