Severity: 2-Critical


Some attack signatures added to an existing signature set may not be utilized by Policies associated with the signature set, despite the attack signatures being reported as now present in the Policies.


The additional attack signatures added to the attack signature set will show up in the Policies utilizing the signature set however the Policies will not actually use those additional attack signatures.


1. Have one or more policies utilizing a manual attack signature set. 2. Update the attack signature database by installing an ASU or creating a custom attack signature. 3. Update the previously created manual attack signature set with one or more attack signatures which were not updated by the ASU (if ASU installed) or are not the newly created custom attack signature (if new custom signature created).


There are two workarounds: 1. When adding additional attack signatures to a Policy, place them in a new attack signature set rather than re-using an existing signature set. 2. If adding signatures to an existing set, afterwards create a new custom attack signature, add it to a new manual attack signature set, add the set to any active policy and then remove the set from the policy (the set and signature can then be deleted if desired). Both workarounds will result in all attack signatures listed as present in all Policies being fully and properly utilized by the Policies.
