According to the SANS Institute "the majority of the successful 
attacks on operating systems come from only a few software vulner-
abilities." To help administrators identify and prioritize these 
weaknesses, SANS has updated their list of vulnerabilities for UNIX 
systems, including:

*  Remote Procedure Calls (RPC) 
*  Apache Web Server 
*  Secure Shell (SSH) 
*  Simple Network Management Protocol (SNMP) 
*  File Transfer Protocol (FTP) 
*  R-Services -- Trust Relationships 
*  Line Printer Daemon (LPD) 
*  Sendmail 
*  General Unix Authentication -- Accounts with No Passwords or 
   Weak Passwords

For more information on how to identify and correct these weaknesses,
