We are trying to minimise the ability of users logging on directly as root. By forcing them to log on as their own accounts and then su'ing to root, we can audit who has done what better.
/etc/default/login has CONSOLE=/dev/console which stops people logging is as root remotely when they use telnet.
However, now we are moving towarss SSH, I tried using PuTTY and found out that you CAN log in as root remotely with this product!
Does anyone know why this is allowed and how it can be stopped?
