The A10 Networks ADC, when used to load balance web applications, must strip HTTP response headers.
An XCCDF Rule
Description
Providing too much information in error messages risks compromising the data and security of the application and system. HTTP response headers can disclose vulnerabilities about a web server. This information can be used by an attacker. The A10 Networks ADC can filter response headers; this removes the web server’s identifying headers in outgoing responses (such as Server, X-Powered-By, and X-AspNet-Version).
