Authentication Logging?

[anubis01]

I'd like to log who logs in (as root or as user) and the time and date of the authentication in combination with a line that says login failed/was successful.

Is there a security tool/program that allows me to do the above?

Can you recommend any other security tools to check if somebody is trying to break into a server?

if you have a syslogger installed like syslog-ng logins should be recorded in /var/log/messages
