Computerworld - Instant messaging has fought the battle for business turf and won. The use of IM in the corporate sector has reached mainstream status, and it's a welcome productivity boost.
"Before IM, we had too many salespeople who had to get up and go meet face to face because someone couldn't be reached. And with e-mail, you have a latency issue, so employees would get up and go talk to each other," says Josh Stallings, vice president of strategic initiatives at No Red Tape Mortgage in Sherman Oaks, Calif.
"Now our people are on the phone all day because they can [simultaneously] IM our processing team to get the information they need for our clients," he says.
IM is a real-time text communications technology with which messages can be sent, received and viewed immediately.

"We have a very well-defined, -controlled and -monitored electronic perimeter," he says. "We know what can leave our organization and what can come in. That is clearly the first and most important step when you want to introduce anything new onto the network."

Address risks that arise from change. Simply adding IM to the network, like adding any software, introduces risk. "It's not because it happens to be IM. Anytime we add something new to our environment, there are security and privacy considerations," says MacLeod. "You need to determine whether it has altered the
