Discussion

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

Check Content

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

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
