Security Posture by Example
Scenario 5 - Heightened Threat, Increased Monitoring
This scenario is similar to Scenario 3 except the CSAF/VEX comes back with
- status = NOT_AFFECTED
- status justification = vulnerable_code_cannot_be_controlled_by_adversary.
Although the HMO does trust that the vendor used the correct status justification, the HDO security policy is to increase monitoring in this situation. So the CACAO playbook increases monitoring on the device with the potentially vulnerable component.
Here is the policy as implemented in CACAO . See here for the actual CACAO playbook. See here for interfacing with the PACE system using OpenC2 commands.
