Finding latest successful logins and failed attempts to a CentOS server

http://serverfault.com – I'm looking for a log file or any service to report the latest login attempts which have failed due to username/password miss match. Is there such utility available for CentOS? (built-in is preferred) My second question, and more generally, I need a log file of penetration attempts to my server. Ideally, this log should contain all attempts including logins, httpd activities, and other conventional open ports. (HowTos)
