Allow/Deny Rules for Headers

  • Last updated on
You can enforce strict limitations on incoming headers intended for a service using SECURITY > Allow/Deny Rules > Header : Allow/Deny Rules section. It is used to sanitize HTTP headers that carry sensitive information identifying the client and some application-specific state information passed as one or more HTTP headers. A header ACL can be configured to protect against attack types and potentially malicious metacharacters and keywords that are placed in a header.

To create a Header ACL rule:

  1. Go to the SECURITY > Allow/Deny Rules page.
  2. In the Header : Allow/Deny Rules section, identify the Service to which you want to add the header ACL rule.
  3. Click Add next to the Service. The Create Header ACL window appears.
  4. Specify appropriate values for the given fields and click Save.
