Session Lock Initiated, v1.0

Defines conformance and assessment criteria for verifying that an information system initiates a session lock at user request or after a defined period of inactivity.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Assessment Step

1
Session Lock Initiated (SessionLockInitiated)
Does the information system prevent further access to the system by initiating a session lock after [Assignment: organization-defined time period] of inactivity or upon receiving a request from a user?
Artifacts
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
A2
Provide the system's session lock timeout value in minutes.
Parameter
Session Lock Timeoutrequired
NUMBER : Provide the timeout period (in minutes) after which a session is locked due to inactivity.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.
