Discussion

Limiting the number of logon attempts over a certain time interval reduces the chances that an unauthorized user may gain access to an account.

Check Content

Verify the SLES for vRealize enforces a delay of at least "4" seconds between logon prompts following a failed logon attempt.

Review the file "/etc/login.defs" and verify the parameter "FAIL_DELAY" is a value of "4" or greater. 

Procedure:

# grep FAIL_DELAY /etc/login.defs

The typical configuration looks something like this: 

FAIL_DELAY    4

If the parameter "FAIL_DELAY" does not exists, or is less than "4", this is a finding.

Configure SLES for vRealize to enforce a delay of at least "4" seconds between logon prompts following a failed logon attempt.

Edit the file "/etc/login.defs". Set the parameter "FAIL_DELAY" to a value of "4" or greater.
