[edit] Description
This rule detects when a user attempts to log into an account that has been configured to deny access. For example, system accounts (root, sys, bin, etc.). This is configured by the user or OS vendor, and is not controlled by Atomicorp software. Disabling this rule will not allow users to log into these "forbidden" accounts, it will simply prevent the software from telling you when this occurs, or taking any action to protect the system from attacks against these accounts. Do not disable this rule.
