Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-3 enforces access decisions that can be scoped to the correct session context.

AC-4 controls information flows between entities, reducing cross-session leakage.

SC-4 directly stops unintended transfer of data through shared resources that different sessions may access.

SC-39 isolates execution domains so one session cannot reach another's state or data.

PR.AA-05 partial match
prevents

Enforcing authorization policies and least privilege can prevent cross-session data exposure when session separation is treated as an access rule.

PR.DS-10 partial match
prevents

Protecting data-in-use directly addresses runtime leakage of session data to unauthorized contexts.

PR.IR-01 partial match
prevents

Logical access controls and segmentation can be applied to isolate session state within applications or environments.

finds

Security testing can detect the weakness but does not itself implement the preventive control.

prevents

Secure development lifecycle practices include session-management controls that prevent exposure of data to the wrong session.

prevents

Application security requirements explicitly call for proper session isolation and state management.

prevents

Secure system architecture principles require isolation of session state to avoid cross-session data leakage.

prevents

Secure coding standards mandate correct session handling to prevent exposure of data elements to the wrong session.

mitigates

Information access restriction directly enforces session boundaries so data is not exposed to the wrong session.
