Barracuda takes on DDoS attacks with firewall product upgrade

Barracuda Networks has today announced the launch of new security capabilities for its Barracuda Web Application Firewall, as the vendor encourages enterprises to set up improved defences against DDoS and other attacks.

A nod to an intelligence-based approach - something that was frequently endorsed at RSA security conference in London last week – is evident in the new 7.7 version of the Web Application Firewall, as Barracuda enhances IP reputation analysis and rate of access controls.

The company claims the former feature tracks numerous characteristics of a client to determine their IP reputation, including their location and whether their access is from an anonymous proxy. Administrators can therefore allow or deny access to an application based on the user’s IP profile. The latter controls calculate access levels based on the rate of data flow per service, which enables network managers to prioritise certain traffic and tighten defences.

Barracuda also touts expanded security coverage “beyond critical systems” in the service update, which protect against advanced threats like Cross Site Request Forgery (CSRF) and HTTP Parameter Pollution.

The firm’s focus on DDoS, or Distributed Denial of Service attacks, comes after a series of high-profile security breaches executed by this long-standing method, where the perpetrator typically floods their target with enough traffic to bring their network down. Last month, DDoS attacks were used in the cyber assault on US banks including JPMorgan and Bank of America, who both suffered problems with their websites as a result.

“While denial of service disruptions focused on flooding network traffic or exploiting weaknesses in network protocols are anything but new, the attacks have reached new heights with tech-savvy attackers focusing on the application layer,” said Stephen Pao, vice president of product management at Barracuda Networks. “By integrating our rich portfolio of security analysis and traffic management technology assets, we can offer a totally integrated Web application security offering unmatched by other vendor solutions,” he said of the new release.

Barracuda Web Application Firewall 7.7 is available immediately with prices ranging from £4,499 to £62,949, depending on the model. Existing customers on the current hardware platform who have an active Energize Update subscription can take advantage of the new release for free. More product details are available via Barracuda’s website.
