AC-17 (04)Remote Access | Privileged Commands and Access

Moderate
High

>Control Description

(a) Authorize the execution of privileged commands and access to security-relevant information via remote access only in a format that provides assessable evidence and for the following needs: organization-defined needs; and (b) Document the rationale for remote access in the security plan for the system.

>FedRAMP Baseline Requirements

No FedRAMP-specific parameter values or requirements for this baseline.

>Discussion

Remote access to systems represents a significant potential vulnerability that can be exploited by adversaries. As such, restricting the execution of privileged commands and access to security-relevant information via remote access reduces the exposure of the organization and the susceptibility to threats by adversaries to the remote access capability.
