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.

installing both racf/vm and dirmaint 
all linux virtual server guests will be defined with LBYONLY and a LOGONBY 
for the sysprogs
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.

Thanks
