A Real Menace to Corporations
"Image-based spam is a particularly difficult problem for a couple of reasons," noted Michael Osterman, founder and principal of Osterman Research. "It is much harder to detect with conventional spam-filtering and blocking technologies. Further, it is typically much larger than normal text-based spam, consuming much more bandwidth and storage."
"Traditional anti-spam software depends on content filtering techniques such as keyword filtering and Bayesian analysis to detect spam. Even the technology used to recognize characters from images, Optical Character Recognition (OCR), is not effective on today's image spam," said Dr. Paul Judge, chief technology officer of Secure Computing. "Spammers are using advanced mathematical and graphical techniques like random modification of image pixels and dynamic construction of images from multiple components to bypass spam filtering tools."
Secure Computing's TrustedSource(TM) Stops Image Spam
Organizations cannot afford to depend solely on localized protection using algorithms that quickly become obsolete and cannot accurately filter new threats like image spam. Secure Computing has evolved its TrustedSource engine over the years to dynamically detect and block traffic from illegitimate sources using a global reputation approach. TrustedSource collects information on email senders and the types of email they generate by accumulating data from more than 7000 sensors located in 48 countries. As it gets more data, the breadth and depth of the TrustedSource database increases, accurately categorizing sender reputations for multiple identities including IP, domain and URL reputations. This approach has proven effective to proactively delete image spam before it hits the corporate mail server.
Baptist Health Systems has long depended on Secure Computing's IronMail with TrustedSource to battle messaging threats such as image spam to keep productivity levels from becoming significantly reduced.
"Baptist Health Systems has been working with Secure Computing's solutions for quite some time and has been battling spam of all forms using the TrustedSource technology," said Phillip Moses, exchange messaging engineer at Baptist Health Systems. "As spammers changed their methods, we, like the rest of the world, saw an increase in image spam, and recent trends show the problem is only going to get worse. Fortunately, our use of IronMail with TrustedSource has helped us to battle against this increase and we will continue to look to Secure Computing to help us fight image spam."
