Check Text (C-215337r991588_chk)
From the command prompt, run the following command to check the default "logindelay" value:
# lssec -f /etc/security/login.cfg -s default -a logindelay
The above command should yield the following output:
default logindelay=4
If the above command displays the "logindelay" value less than "4", this is a finding.
Fix Text (F-16533r294463_fix)
From the command prompt, run the following command to set "logindelay=4" for the default stanza in "/etc/security/login.cfg":
# chsec -f /etc/security/login.cfg -s default -a logindelay=4
