Cisco extends security controls to 'dark Web'

New usage controls added to IronPort S-Series Web Security Appliances

Cisco is tackling the so-called "dark Web" of online content that's not easily indexed or categorized by adding new usage controls to its IronPort S-Series Web Security Appliances. The new technology is packaged as a software blade that works with Cisco's URL filtering database to make decisions about user Web surfing to enforce acceptable-use policies.

The IronPort Web Usage Controls software has an engine that reads a Web page on the fly and analyzes the content to decide if it's objectionable or off limits according to corporate policy, says Vivek Bhandari, a product marketing manager at Cisco. Simply categorizing Web sites into lists -- such as sports, shopping, hate sites or porn -- is no longer sufficient because the Internet is now filled with highly transient and often dangerous sites that comprise the dark Web.

"These sites are coming up and down so fast," Bhandari says, noting that the proliferation of blogs and social networking sites, with Web 2.0 technology underpinnings, are also contributing to an explosion in Web content. The dark Web may constitute 80 per cent of objectionable content, outside the 20 per cent of Web sites that can still be put neatly into list form, Cisco says.

Cisco's S-Series appliances can perform malware detection and blocking. The new Web Usage Controls software adds the ability to monitor, block or warn users about Web traffic based on a method that combines URL filtering lists with contextual heuristics for analyzing content and checking hidden tags. Cisco's URL filtering database includes 65 URL categories and is updated every 5 minutes through Cisco's security intelligence operations.

With the configuration Cisco is advising customers to use, about 90 per cent of objectionable dark Web content violating policy will be detected via IronPort Web Usage Controls without causing the false positive rate to spike, Bhandari says.

IronPort S-Series appliances with Web Usage Controls, available now, start at $US8,500.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
