Imperva says anti-virus spend not proportional to effectiveness

Imperva-logo(LiveHacking.Com) –  The business security firm Imperva has conducted a study together with students from The Technion – Israeli Institute of Technology into the effectiveness of anti-virus products and come up with some startling numbers. According to the report, only 5% of new viruses are detected with the existing techniques used by anti-virus products. In time the anti-virus vendors do update their signature databases but, put simply, the majority of anti-virus products can’t keep up with the rate of virus creation and propagation.

What this means is that if the detection of new, previously unknown viruses is used as the measure of success then consumers and businesses are spending a total of $7.4 billion a year on anti-virus products that don’t work. A lot of this spend comes from Enterprises attempting to adhere to some compliance standard. Imperva suggest that relaxing anti-virus compliance standards could free money which could be spent on other security software.

“One reason why security budgets devote too much money to antivirus is compliance. Easing the need for AV could free up money for more effective security measures,” wrote Imperva in the report.

Imperva recommends that existing anti-virus software should remain in place, but that security teams should use more resources on identifying aberrant behavior such as unusually fast access speeds or large volume of downloads.

The report also noted that the best way for a piece of malware to have long term success was to shun popularity. Antivirus products are much better at detecting malware that spreads quickly as the malware appears quickly on the radar of the anti-virus companies. However malware which has a limited distribution (such as government sponsored attacks) usually have a prolonged window of opportunity.
