Phase 2: Pull up the drawbridges

• Disable ports/services you do not need.

• Examples:

• ftp (port 21) ident (113)

• telnet (23) netbios (139)

• smtp (25) http (180)

• pop3 (110) imap (123)

• finger (79)

• (If needed later, can be activated at that time

• along with appropriate ipchains rules.)
