12.3 Session locking (FTA_SSL)

Family behaviour

This family defines requirements for the TSF to provide the capability for TSF-initiated and user-initiated locking and unlocking of interactive sessions.

Component levelling

FTA_SSL.1 TSF-initiated session locking includes system initiated locking of an interactive session after a specified period of user inactivity.

FTA_SSL.2 User-initiated locking provides capabilities for the user to lock and unlock the user's own interactive sessions.

FTA_SSL.3 TSF-initiated termination provides requirements for the TSF to terminate the session after a period of user inactivity.

Management: FTA_SSL.1

The following actions could be considered for the management activities in FMT:

a)    specification of the time of user inactivity after which lock-out occurs for an individual user;

b)    specification of the default time of user inactivity after which lock-out occurs;

c)    management of the events that should occur prior to unlocking the session.

Management: FTA_SSL.2

The following actions could be considered for the management activities in FMT:

a)    management of the events that should occur prior to unlocking the session.

Management: FTA_SSL.3

The following actions could be considered for the management activities in FMT:

a)    specification of the time of user inactivity after which termination of the interactive session occurs for an individual user;

b)    specification of the default time of user inactivity after which termination of the interactive session occurs.

Audit: FTA_SSL.1, FTA_SSL.2

The following actions should be auditable if FAU_GEN Security audit data generation is included in the PP/ST:

a)    Minimal: Locking of an interactive session by the session locking mechanism.

b)    Minimal: Successful unlocking of an interactive session.

c)    Basic: Any attempts at unlocking an interactive session.

Audit: FTA_SSL.3

The following actions should be auditable if FAU_GEN Security audit data generation is included in the PP/ST:

a)    Minimal: Termination of an interactive session by the session locking mechanism.
