Encryption is handled by the applications above the modem layer. It is possible to send encrypted data down a modem line. The insecurity comes from the fact that anyone is capable of connecting to the modem simply by dialling it and then can brute force there way onto a system. Also most modems are left on systems by non-administrators (ie some guy in the off) who do not make any attempt to secure them.

Which is caused by the limited amount of packets than can be sent over dial up speeds. -----Original Message----- From: Adnan Ali [mailto:call_ret () yahoo com] Sent: Wednesday, April 21, 2004 4:30 AM To: security-basics () securityfocus org Subject: A question about modem security I have read somewhere that dial-up questions using modems are inherently insecure. Can somebody please explain to me why it is so? Thanks, __________________________________ Do you Yahoo!? Yahoo!
