Check Text ( C-27975r1_chk )
Use the last command to check for multiple accesses to an account from different workstations/IP addresses. If users log directly onto accounts, rather than using the su command from their own named account to access them, this is a finding (such as logging directly on to Oracle). Also, ask the SA or the IAO if shared accounts are logged into directly or if users log on to an individual account and switch user to the shared account.

Fix Text (F-24339r1_fix)
Use the switch user (su) command from a named account login to access shared accounts. Maintain audit trails that identify the actual user of the account name. Document requirements and procedures for users/administrators to log into their own accounts first and then switch user (su) to the shared account.
