Title

IBM z/OS SMF recording options for the FTP Server must be configured to write SMF records for all eligible events. (Cat II impact)

Discussion

The FTP Server can provide audit data in the form of SMF records. The SMF data produced by the FTP Server provides transaction information for both successful and unsuccessful FTP commands. Failure to collect and retain audit data may contribute to the loss of accountability and hamper security audit activities. Satisfies: SRG-OS-000032-GPOS-00013, SRG-OS-000392-GPOS-00172
