cyberstrikeus Ensure ServerSignature Is Not Enabled (Automated)
Profile Applicability
- Level 1
Description
Disable the server signatures which generates a signature line as a trailing footer at the bottom of server generated documents such as error pages.
Rationale
Server signatures are helpful when the server is acting as a proxy, since it helps the user distinguish errors from the proxy rather than the destination server, however in this context there is no need for the additional information.
Audit
Perform the following steps to determine if the recommended state is implemented:
Verify the ServerSignature directive is either NOT present in the Apache configuration or has a value of Off.
Remediation
Perform the following to implement the recommended state: Add or modify the ServerSignature directive as shown below to have the value of Off:
ServerSignature Off
Default Value
The default value is Off for ServerSignature.
