It is the statement like this that makes me almost fall off my chair. What planet are you coming from? What make you think that these IM is secured (excluding the gapping hole in AIM). Remember, you have to connect the client to an external IM server, the information is traveling in "clear text" including your username and password. What makes you think that these IM servers are secure? Furthermore, your communication can be monitored by a third party. CBAC or stateful Firewall can not prevent this because your session is being monitored on the IM servers. There is nothing that your firewall can do. If hackers successfully hack the IM servers, consider your conversation available to everybody else. The best way to secure communication is running IM over Secure Socket Layer (SSL). I've been using jabber over SSL for a few months now and it is working great. You want something secure, build your own jabber server, run the service over SSL and have your buddies to connect to your jabber IM server for secure communication. Jabber server is a freeware available on Linux platform. ----- Original Message ----- From: "Steven A. Ridder" To: Sent: Sunday, January 06, 2002 11:38 AM Subject: Re: How to block MSN, and others.
