Hi Steve

i see what you mean

<http://bugs.centos.org/view.php?id=1973>

This was meant to be sorted by aide 0.13.1.
I suppose that aide is just going that wee bit further with regards to
security by checking for changes in selinux file contexts

If a file (or process / object) has its context changed then it could
signify an attack especially if you are running the box in enforcing
mode.

I had thought that aide had been patched to allow for null contexts if
compiled to look for them.

I just changed from running selinux in disabled mode on my production
systems to running with selinux enabled (initially in permissive mode
to check for problems then moving to enforcing once the wrinkles were
ironed out).

My main reason for doing so is that we are developing a electronic
patient record for the nhs.
I think selinux is fantastic

it's more about adding extended attributes to the existing filesystem
