A.8.1 User end point devices partial match
degrades

Endpoint device configuration can enforce cache-clearing or no-cache policies for sensitive web content.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly require no-cache headers or cache-control directives for sensitive pages.

A.8.28 Secure coding partial match

Configuration management can mandate secure browser cache settings across the estate.

A.8.23 Web filtering none match
none

Web filtering can block risky sites but does not directly govern browser caching of sensitive data.
