Instant messaging, just like email or VoIP traffic, needs to be secure from eavesdroppers, man-in-the-middle attackers, and other security threats. Many IM clients can tunnel messages over transport layer security (TLS) to provide encryption, including XMPP (a.k.a. Jabber), IRC, and the OSCAR protocol used by AIM. TLS provides authentication and encryption at a low level, but a considerably secure solution for IM is a protocol called Off The Record (OTR). Pull up a chair and secure your instant messaging today.
