Umask recommendation

What is the "generally accepted" recommendation for the system umask setting for an AIX 5.3 system ?  

Our non technical auditors are recommending 026.

There is no real generally accepted umask, it really depends on how secure you want to make your own system.

The default of 022 is pretty open, and will allow everyone on the system to access and list directories and read files.

For tighter security you should make the umask 027 or 077 (default is set in /etc/security/user).

Absolute minimum is 002 - no write by unknown
Some use 027 - no write for group, no access to others.
026 has no big advantage over 027 - it gives others ability to execute your programs, which is impractical at best.
I do use 002 because users need to change some files in g+s directories, and all users are trusted to the degree to allow accessing any file when needed.

Any objections should be posted here in the next 4 days. After that time, the question will be closed.
