Mitigation guidance
- Apply vendor-provided patches or firmware updates as available.
- Implement compensating controls such as network segmentation, access controls, and strict update management.
- Validate patches in a test environment before deployment to production systems.
- Maintain a routine vulnerability management process with asset discovery and prioritization by risk.
How to stay informed
