IM (Instant Messaging)

Another danger to workstations is the use of IM or Instant Messaging Services/Software. Some of the dangers:

Sends and receives file attachments (worms, viruses, etc)

Mass mailers use to distribute themselves to all members of your buddy list.

Ripe medium for on-line scams, identity theft, and other predatory behavior.

SPIM is spam sent over IM containing offensive language or links to web sites, etc.

Until IM becomes a more secure medium, the best protection is your own education and watchfulness. The following security tips go a long way toward making IM more safe.

• Use a solid account password and change it often. To learn more about creating and maintaining strong passwords, read our password security article.
• Keep your IM software up to date.
• Keep your operating system and security software up to date.
• Don’t send credit card numbers, Social Security Numbers, or any other vital information over IM.
• Don’t open attachments or click on Web links sent by someone you don’t know.
• Even if you know who sent a Web link, hover over the link with your cursor before clicking it to check whether the Web address seems legitimate.
• Don’t send files over IM unless you have no other alternative, and never send files containing information you want to keep private.
• Be wary of odd behavior. If a person on your allowed list is sending strange messages, terminate your IM session and contact them over the phone or on email.
• Protect your computer and data with an anti-virus program.
• Install a good firewall. Some provide additional protection for IM services such as Norton and ZoneAlarm.

Take advantage of third-party encryption and authentication tools—but only if they’ve received solid reviews.
