Question When to create a user & group for an app?


Some programs in linux have their own user and group, like mysql and apache. I know it is to limit the breach that can occur if that app is exploited. When should we create a dedicated user and group for an application? Should all daemons have their own user and group? Only networked daemons?

Right now I am looking at using swatch on my system to monitor logs. I wonder if i should create a user and group for it to run under.

All files, including executables (applications), have an owner and a group assignment.
Privileges are controlled by the assignment of the owner and group and by the permission codes.

You have more options for control of access than you can imagine....

Ya think!?

I expect these types of responses on forums allowing referral links in sigs. Your response is pointless IMHO, unless you want to reach 5000 posts this week.

I don't think there is any hard-and-fast rule to say when you should create a user and group for a particular program. If I were forced, I'd say each daemon, especially one with the ability to acquire root-like privileges (switching users) or has a large amount of data to read/write, should be run under a unique user/group combination. The opposite end of the spectrum has a user/group for every piece of software installed (for a unique method of package/software management) - see Linux from scratch; I think "pkguser" is the name of the package management method that does this if you're at all interested.

As for pixellany's response... well, I think there are times when people don't really read a post to understand exactly what's being asked or jump to a likely conclusion. It happens... it's happened to a number of my posts as well. Don't sweat it - unless the response causes the thread to get hijacked.

WTF????
I would send you an e-mail, but you don't have that enabled...
I post when I think I can help---period. Please accept that the wording of your post suggested that mine might have been useful. It is hard to understand why it should have upset you. I suggest that you stay on topic and avoid little zingers like this.
Good luck in all your Linux endeavours....
