Changing Herald in AIX

Here are two ways to customize the AIX login prompt.

The first way is to add a "herald" in the default stanza in the /etc/security/login.cfg file as follows

default:
sak_enabled = false
logintimes =
logindisable = 0
logininterval = 0
loginreenable = 0
logindelay = 0
herald = "AIX TIGER HOME\r\nID:"

The second method uses the "chsec" command to modify the same file:

chsec -f /etc/security/login.cfg -s default -a herald="AIX TIGER HOME\r\nID:"

Note: for additional security, I recommend changing the standard Unix "login" prompt to something else like "ID". The "login" prompt almost invariably identifies the system as Unix to hackers.
