2011 Mid-Year Security Report
After analyzing the dynamic and interrelated nature of Web-based malware ecosystems, the 2011 Mid-Year Web Security Report concludes that: Malware hosting is often found within categories, such as Online Storage and Software Downloads, that companies typically allow in acceptable use policies; Businesses should consistently block Pornography, Placeholders, Phishing, Hacking, Online Games and Illegal/Questionable categories to follow best practices for Web security; Searching for images and pirated media ranks at the top of the list for possible malware delivery, and users engaging in these activities are especially vulnerable; A single defense layer, such as a firewall or anti-virus software, is insufficient to protect against the dynamic nature of malware and the extensive infrastructure of malware delivery networks. Instead, businesses need the real-time protection and intelligence that a cloud-based Web defense can deliver as it quickly expands and adapts to new threats.
