Tape Bypass Label Processing (BLP) is extremely sensitive, as it allows the circumvention of security access checking for the data. This could result in compromise of customer data.
a) Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ATTTPBLP) Automated Analysis Refer to the following report produced by the ACF2 Data Collection Checklist: - PDI(ACF0800) b) If the number of users granted the special privileges TAPE-LBL or TAPE-BLP is strictly controlled and limited to systems programmer and operations personnel, there is NO FINDING. c) If the number of users granted the special privileges TAPE-LBL or TAPE-BLP is not strictly controlled and limited to systems programmer and operations personnel, this is a FINDING.
The IAO will ensure Logonids with the TAPE-LBL or TAPE-BLP are kept to a minimum and are controlled and documented. Review all LOGONIDs with these attributes. Tape label bypass (BLP) privileges will be restricted at the user level. Specify one of the following two logonid privileges to grant a user access to BLP processing: User LID Record: TAPE-LBL TAPE-BLP It is possible to grant selected programs to bypass tape label processing regardless of the BLP related privilege of the logonid executing the program. This capability will not be used due to the requirement that accounting of BLP processing be done at the user level. Do not utilize the GSO BLPPGM record.
