Astaro, a unified threat management vendor, has released its Web Application Security that protects web servers and Outlook Web Access from sophisticated attacks like SQL injections and cross site scripting.

The new security application adds new functionalities to the Astro Security Gateway, such as Web Application Firewall; and URL Hardening that forces visitors to interact with users servers in a way that is correct and expected.

The new application ensures that cookies given out to visitors by users web servers have not been tampered with; and offers two separate scanning engines to operate in parallel to scan and block content.

Gert Hansen, vice president of product management at Astaro, said: "Astaro URL Hardening registers which valid objects are given to a visitor by the web server, signs them, and examines their subsequent requests, rejecting them if they are not expected and correct.

"The administrator does not have to waste time creating and checking rules, as the Astaro Security Gateway works directly with how the web server interacts with visitors."

The company claims that the Astaro Web Application Security allows IT administrators to protect their web servers against nine of the Open Web Application Security Project (OWASP) Top 10 Risks.
