A known vulnerability exists on a production server, but patching is delayed due to operational...

Virtual Patching is a risk-mitigation technique emphasized in CEH v13 Security Operations. It involves deploying compensating controls—such as WAF rules, IPS signatures, or firewall policies—to block exploitation attempts without modifying the vulnerable system.

CEH v13 highlights virtual patching as especially useful when:

Downtime is unacceptable

Vendor patches are delayed

Legacy systems are in use

Monitoring alone does not prevent exploitation, and shutting down systems is often impractical. Virtual patching provides immediate protection while maintaining availability.
