In 2004, information security professionals will experience more of the darker side of human behavior, but organizations will also take more control over their network and computing infrastructures, particularly end-user systems. Here are my predictions on what to expect in information security in the next year.
Spam operators are getting more creative in their efforts to get around spam filters. R.a..n,d,o.,m p,u,,n,c.t,,u_a.t.1..0.n makes it nearly impossible to block spam messages by filtering keywords. Operators are changing to GIF (Graphics Interchange Format) images with no searchable text. Some spammers send messages in encoded formats, like Base64, to circumvent keyword filters altogether, and relay through IP addresses that have no Domain Name System domains associated with them. These recent developments are challenging spam-filter vendors and frustrating users.
