- 3.1.10[a]the period of inactivity after which the system initiates a session lock is defined.
- 3.1.10[b]access to the system and viewing of data is prevented by initiating a session lock after the defined period of inactivity.
- 3.1.10[c]previously visible information is concealed via a pattern-hiding display after the defined period of inactivity.
