Security Question: Lock after invalid login, Session Lock and Required Minimum Password Length
Hello all,
If anyone has time, I have a few questions:
How do I do the following in Linux. We are using Red Hat and Oracle Enterprise Linux, which is based on Red Hat too.
1. How to lock the account after a few (like 3) invalid password attempts?
2. How do you lock a screen after 30 minutes of inactivity?
3. How do you require a minimum password length when changing passwords or creating a new account?
Thanks in advance for any help.
