Why these techniques?
Remote management application bypass enables exploitation of public-facing service (T1190); high-priv requirement and vague bypass description limit additional mappings.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires server-side enforcement of access decisions rather than trusting client-side checks that can be bypassed.
Mandates server-enforced information flow policies so that protection mechanisms cannot be evaded by client-side logic.
Requires a tamper-proof reference monitor that is always invoked, eliminating reliance on client-side security enforcement.

Secure architecture principles discourage client-side trust but do not directly address this weakness.
Security testing can detect client-side enforcement but is not the primary mitigation.
Information access restriction is undermined when the client is trusted to enforce it.
Secure development lifecycle mandates server-side validation and prevents reliance on client enforcement.
Application security requirements explicitly call for server-side enforcement of security mechanisms.
Secure coding standards require server-side checks and reject client-only enforcement.
