!Basic Machine Security:
-* Don't use protocols such as telnet or ftp between machines on an untrusted network such as the internet - these send usernames and passwords around in clear text. Anonymous ftp is OK - you don't give away your details. Instead look into ssh (Secure Shell). This encrypts all data between the machines.

(Secure Shell). This encrypts all data between the machines.
* Don't run unnecessary services (called "daemons" in UNIX) that allow internet connections - some distributions turn these on by default. Examples are mail or news servers and printer daemon (lpd). If you want to see a list of the daemons running on your machine, at a command prompt type:%%% netstat -aAinet%%%The lines that say "LISTEN" means a daemon is waiting for connections on the specified port.

+GNU Privacy Guard ([GPG]) is an encryption program compatible with Pretty Good Privacy ([PGP]). It uses public-key cryptography, and many email clients have hooks that allow you to fairly easily encrypt and "sign" email. See our [GPG/PGPNotes] page.
