Title
If an automated scheduler is used to provide updates to the sensors, an account on the file server must be defined that will provide access to the signatures only to the sensors. (Cat II impact)
Discussion
In a large scale IDPS deployment, it is common to have an automated update process implemented. This is accomplished by having the updates downloaded on a dedicated secure file server within the management network. The file server should be configured to allow read-only access to the files within the directory on which the signature packs are placed, and then only from the account that the sensors will use. The sensors can then be configured to automatically check the secure file server periodically to look for the new signature packs and to update themselves.
Check Content
Review the file server accounts and determine if the accounts with read access to the IDPS signatures are provided only to the IDPS sensors. If there are accounts other than those allocated for the IDPS sensors providing access to the signatures, this is a finding.
Fix Text
Secure the signatures from access to accounts for IDS updates.
