ASE generated error messages for blocked requests

The API Security Enforcer (ASE) blocks certain requests based on application programming interface (API) Mapping or API Behavioral Security (ABS)-detected attacks. For these blocked requests, it sends a standard error message back to the client.

After receiving ASE access logs and API JSON configuration files, ABS applies AI algorithms to track API connections and detect attacks. If enable_abs_attack is true, ABS sends deny list to ASE, which blocks client identifiers, such as API keys, usernames, cookie, IP address, and OAuth token on the list.
