Evaluate the impact of correcting any deficiencies. Develop a plan of action and implement the required changes.
Ensure the following items are in effect for all MCS consoles:
Define a profile protecting the use of the CONSOLE command within TSO. A sample command to accomplish this is shown here: RDEF TSOAUTH CONSOLE UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ))
Permit only authorized users. A sample command to accomplish this is shown here: PE CONSOLE CL(TSOAUTH) ID(<syspsmpl>)
