Created by Sanjay Kumar, Modified on Thu, 5 Sep, 2024 at 7:30 AM by Sanjay Kumar

Below is an example about building compliance policies from the CVEs.

We will be using CVE-2018-0282 for this case.

(1) Compliance -> (2) Policies -> (3) New -> (4) Name: CVE-2018-0282 -> (4) Save

Under Node Group (1) New -> (2) Name: Cisco_IOS -> (3) Save

If we scroll through the CVE article below is the information we derive:

So, we would be building rule and condition to identify these lines in the configuration.

Under Rule (1) New -> (2) Name: http_check -> (3) Rule type: Configuration -> (4) Vendor : Cisco_IOS

Under Rule (1) New Logic -> (2) Logic: if A then ( B or C) -> (3) Save

Define (A) to match the software version that is vulnerable:

Under Condition (1) A -> (2) Type: Software version -> (3) Must contain : 15.5(2) -> (4) Save

Define B:

This is to match the first line of config lines in the CVE document

(1) B -> (2) Must contain: ip http server -> (3) Save

Define C

This is to match the next lines of config from the CVE article

(1) C -> (2) Must contain: ip http secure-server -> (3) Save

This completes the creation of the policy.
