file permissions for /usr/bin/postgres

От

Hi

 

Can someone please advise what the most secure permissions are allowed for /usr/bin/postgres ?

At the moment we have:

 

-bash-3.2# ls -lt /usr/bin/postgres

-rwxr-xr-x 1 root root 4574696 Jan 28 19:31 /usr/bin/postgres

 

This is not considered secure.

 

Regards,

"Not considered secure" by whom, and on what grounds?  Those are pretty
much the standard permission settings for any executable in /usr/bin.
What threat do you suppose you'll ameliorate by changing them?
