What Businesses Need to Know About Reputation-Based Messaging Technology

Sunday, April 1st, 2007

I first started hearing about reputation-based technologies used in conjunction with filtering messages a couple of years ago. What a great idea! It does make sense to analyze the characteristics of a message to help determine whether or not it is legitimate, spam, contains malware, or is likely to be some other type of message you do not want getting onto your corporate network, doesn’t it? Trying to determine the “reputation” of the message seems to be a good additional check. Banks and credit card companies have been doing similar types of activities for decades, looking at the reputation of their loan and card applicants, when generating credit scores. It seems as though this type of analysis, while not fool-proof, could also have the potential to greatly assist with keeping unwanted messages from clogging the enterprise networks and mailservers.

Have you noticed an increasingly large number of email messages coming into your inbox that have the text information imbedded within graphic images? I have, and they really bug me. I know they irritate many of my information assurance professional colleagues as well. Some of these spam messages are very creative. All clutter my already overflowing email. They waste precious storage, and also clog bandwidth on enterprise networks. This is image spam.
