In this comprehensive IM tutorial, you'll gain insight into instant messaging and how this real-time messaging application can enhance not only your communication processes, but can also be embedded into your business processes to significantly enhance collaboration and productivity. You'll find information on the standards and protocols that support IM, and learn how to manage IM tools on your network (whether you choose to develop an in-house solution or opt for a consumer-grade client). You'll also learn about the security risks and pitfalls associated with IM and how to mitigate those risks.
What is IM?
Instant messaging, often shortened to simply "IM" or "IMing," is the exchange of text messages through a a software application in real-time. Generally included in the IM software is the ability to easily see whether a chosen friend, co-worker or "buddy" is online and connected through the selected service. Instant messaging differs from ordinary email in the immediacy of the message exchange and also makes a continued exchange simpler than sending e-mail back and forth. Most exchanges are text-only, though popular services, such as AOL, MSN Messenger, Yahoo! Messenger and Apple's iChat now allow voice messaging, file sharing and even video chat when both users have cameras.

Instant messaging (IM) has proliferated for consumer and business use, and employees use it to communicate among themselves, and often with people outside the organization. It's affordable, easy to deploy, and increases worker productivity.
But that increased connectivity, if not configured securely, can come with a heavy price. IM allows viruses, Trojans and other malware to piggyback into your networks far easier than email attachments. IM messages can contain links to malicious Web sites, and confidential data can be compromised.

DEFINITION - An IM worm is self-replicating malicious code that spreads in instant messaging networks. When an IM worm infects a computer, it locates the address book for the instant messenger client, which is called a buddy list or contact list, and tries to send itself to all the infected person's contacts.
