Description
A session manager controls the semi-permanent interactive information interchange, also known as a dialogue, between a user and z/VM. Without the use of a session manager these semi-permanent interchanges can be open to compromise and attacks.
ℹ️ Check
Examine running systems. If access is gained to the z/VM system without going through a session manager, this is a finding.
✔️ Fix
Ensure that a session manager is in use with the system.
