Discussion

CA 1 Tape Management default system password is common with all CA 1 systems. With this password, CA 1 tape processing can be deactivated. This could allow for unauthorized access to information stored on tape volumes and the CA 1 Tape Management Catalog (TMC). The result may threaten the integrity and availability of the CA 1 Tape Management System, and compromise the confidentiality of customer data.

Fix

The systems programmer/IAO programmer/ISSO will ensure that the CA 1 system password is changed from the vendor default system password. Verify upon installation that the password is not the same as the default password and user distributed with the original installation default.
