Interview the SA to determine if any shared accounts exist. Any shared account must be documented with the IAO. Documentation should include the reason for the account, who has access to this account, and how the risk of using a shared account (which provides no individual identification and accountability) is mitigated. NOTE: As an example, a shared account may be permitted for a help desk or a site security personnel machine, if the machine is stand-alone and has no access to the network.
