"If you know the enemy and know yourself, you need not fear the result of a hundred battles." Sun Tzu, The Art of War Ebusiness security has never been bigger business and industry experts agree that the best growth is yet to come. Trojan Horse applications (Trojans for short) are not new, having been around for over ten years now, but amazingly no-one has found a way to manage the threat. Ebusiness security has never been bigger business and industry experts agree that the best growth is yet to come. In the summer of 2003 a new email virus hit the front pages of the newspapers worldwide. One of the most noteworthy IT security developments of 2003 is the convergence between spamming and viral techniques, leading to a much more dangerous threat for email users.

Because it can circumvent many existing content-management solutions, instant messaging (IM) is causing security concerns among IT managers, which often leads them to ban its use altogether.
