Official Requirement
Perform periodic scans of the information system and real-time scans of files from external sources as files are downloaded, opened, or executed.
What This Means in Plain English
Your anti-malware tools should scan files in real-time (as they are opened, downloaded, or executed) and also perform scheduled full-system scans periodically to catch anything that might have been missed.
How Petronella Implements This Control
Petronella Technology Group implements this control through:
- Sophos XDR real-time on-access scanning for all file operations
- CrowdStrike Falcon behavioral monitoring scanning all process executions in real-time
- Weekly full-system malware scans scheduled during off-hours
- Microsoft Defender for Office 365 scanning all email attachments before delivery
- FortiGate gateway scanning all downloaded files from the internet in real-time
Assessment Guidance
Assessors will verify that real-time scanning is enabled and functional, check that periodic full scans are scheduled and completing, test real-time detection by downloading a test file, and review scan logs for completeness.
Common Implementation Gaps
- Real-time scanning disabled for performance reasons
- No scheduled periodic full-system scans
- Email attachments not scanned before delivery
- Downloads from the internet not scanned at the gateway
- Scan exclusions too broad, creating protection gaps
