what is the "good" number for "invalid logout attempts"

In a Window based company, they are the policy of 10 times invalid logon attempts.

But, what I usually set on unix based environment is 3 times.

What is the good number, and any reasons for it?

Thanks,

That can be entirely up to management. It could be defined as part of a corporate security policy.

At one job this was set to 5 on the Unix machines, but that was a management decision.

Not so low that is doesn't give the average user enough tries to remember their password. I would say 3-5.
"The difference between me and you? I will read the man page." and "Respect the hat." and "You could just do a search on ITRC, you don't need to start a thread on a topic that's been answered 100 times already." Oh, and "What. no points???"

The highest security level would suggest 1 attempt. This also generates the highest number of calls to fix a locked account. Or change to 10 for a match to your company policy. The same PC users are logging onto the HP-UX system so consistency is more important. Use scripts to monitor lastb to look for potential attacks.
