Security challenges in a Web 2.0 world
Organizations can do more over the Web today than ever before. As use of the Web continues to grow and evolve with adoption of Web 2.0 applications, virus outbreaks and other forms of Web-borne threats known as "malware" continue to grow as well. Are you adequately protected?
Widely deployed reactive security solutions based on a negative security model of blocking "known bad" behavior and content (such as signature-based anti-virus and category-only URL filtering), while providing vital security, were not designed to combat malicious software code or cleverly blended threats, hidden inside seemingly good HTTP or HTTPS traffic. Furthermore, today's malware attacks are rarely Web wide, rather they are targeted at individual organizations. While organizations need the Web, they need to be protected from Web-related attacks targeted at them.
The adoption of Web 2.0 applications by the enterprise requires a security solution for Web 2.0. Secure Computing has taken a fresh look at today's Web security needs and has solved this growing problem: Secure Web (Webwasher) line of security appliances.
Secure Web (Webwasher) Solutions
Secure Web delivers a comprehensive security solution for all aspects of Web 2.0 traffic. When a user is requesting content from a Web 2.0 application, he is implicitly asking for active content to be delivered to, and executed by, his computer. Furthermore, the same user is required to provide content to the Web 2.0 application, making the security concerns both inbound and outbound in nature.
Secure Web (Webwasher) provides immediate protection for user-initiated Web traffic against threats such as malware hidden in blended content or hidden in encrypted SSL traffic. Secure Web analyzes the intent of all content entering the network - even new web pages before they have content and before they are categorized. It also protects organizations from outbound threats such as potential loss of confidential information that can leak out on all key Web protocols (HTTP, HTTPS, and FTP).

SecureCache
Caching was originally designed to speed up content access and reduce the need for the enterprise to purchase expensive bandwidth. Initially the cache was the object of everyone's desire to accelerate applications. As a result, Web 1.0 applications had their own protocols (HTTP, FTP, NNTP, RTSP, etc.) each with their own caching needs.
Web 2.0 applications replace their Web 1.0 predecessors with standard use of HTTP and HTTPS, obsolescing the need for separate protocols supporting separate applications and hence the caching needs they require. Rapid adoption of Web 2.0 applications and wide availability of inexpensive bandwidth dictates a review of how network traffic and application use have changed:
- Decrease in amount of cacheable HTTP content
- Decreased use of FTP
- Streaming media caching for Web 2.0: Flash-based streaming over HTTP
- Obsolescence of news group NNTP caching
- Increased need for security for web traffic as result of changing threat landscape
Key Benefits
Efficient single appliance solution - In today's flat-rate bandwidth world the focus of caching has shifted towards security and delivery time to end-user, not on bandwidth savings. Webwasher delivers security and reduced latency.
A more efficient cache - Some legacy caching solutions first check the object in question against a signature-based anti-virus solution prior to caching the object. Every time a virus signature file is updated, the cache has to be cleared and the file re-fetched from the Internet. In today's Web 2.0 world where hourly updates to virus detection engines are not uncommon - the performance hit is obvious!
Webwasher caches the result of the virus signature scan along with the object. As a result, Webwasher does not have to flush the cache each time a signature file is updated. Instead it only rescans the object the first time it is requested after the update, delivering a significant improvement in caching overhead compared to some legacy solutions.
Security beyond reactive anti-virus signature protection - In addition to signature-based anti-virus protection, Webwasher Anti-Malware applies its #1 rated proactive intent filters to the object per the requestor's policy. Webwasher also checks the object against its latest security reputation according to the requestor's policy. Scanning an object prior to delivery to the desktop for both malware and reputation is unique to Webwasher and provides unparalleled security.
Support for the streaming needs of today's enterprise - Webwasher supports caching of the most frequently used streaming media formats in use today (Flash and RTSP over HTTP), delivering better security integration than legacy caching solutions designed a decade ago.
Webwasher is available as high-performance turnkey appliances for every budget and performance demand as well as software for Linux, Solaris, and Windows platforms.
