It has been a while since I used RACF, but if I remember right those directory entries are overridden by RACF anyways. But if it makes an auditor happy and the CIO sleep better .... well you get the picture.

Dyck Sent: Wednesday, September 26, 2007 9:30 AM To: IBMVM@LISTSERV.UARK.EDU Subject: z/vm security advise requested To keep our auditors happy (assuming that is possible) to secure our z/vm (5.3) environment I am planning on doing the following. Note that our environment is purely in support of linux virtualized servers and the only cms users are the handful of sysprogs supporting z/vm. 1. installing both racf/vm and dirmaint 2. all linux virtual server guests will be defined with LBYONLY and a LOGONBY for the sysprogs 3. all system machines with the exception of Operator will also be defined with LBYONLY and LOGONBY for the sysprogs Does anyone see any issues/exposures with this approach.
