Firewall updated to block XML attacks

Firewall supplier Teros has modified its Secure Application Gateway to block attacks via XML-based web services

Firewall supplier Teros has modified its Secure Application Gateway to block attacks via XML-based web services.

As companies start deploying web services they need to protect software against hackers looking for back doors to exploit. XML offers the same opportunity for buffer overflow, denial of service and SQL injection attacks as HTML applications.

Ray Wagner, an analyst at Gartner, said, "Traditional security infrastructures were not designed to adequately protect web services from attack.

"Many companies are deploying web services alongside traditional web applications, so integrated products that enforce security policies across both types of applications have the potential to deliver more consistent security."

Teros has extended its Deep Stream Inspection product to analyse bi-directional traffic, including SSL-encrypted communications. This enables it to secure applications by checking that they are accessed correctly by authorised users.

Bob Walters, Teros' chief executive, said the protection of web services should be high on the enterprise agenda as they are often interfaced with mission-critical databases and back-office applications, where customer details are stored, for instance.

The Teros Secure Application Gateway costs from £11,100.
