Cisco today launched Cisco® IronPort® Web Usage Controls, a real-time content categorization to accurately identify up to 90 percent of Dark Web sites.
The Product is available as a software blade on the Cisco IronPort S-Series highly secure Web gateway, Cisco IronPort Web Usage Controls includes a dynamic content analysis engine that works in tandem with Cisco's comprehensive URL-filtering database to deliver industry-leading efficacy and coverage across all content types. This combination improves the ability of organizations to manage how and when users can access the Web, eliminating risks associated with misuse, compliance violations and reduced productivity.
The Dark Web:
- The Cisco Security Intelligence Operations (SIO) estimates that more than 80 percent of the Web is "dark," meaning uncategorized by legacy URL-filtering databases. Cisco refers to this as the Dark Web.
- The Dark Web has been formed largely as a result of the de-centralization of content creation ushered in by Web 2.0, including the proliferation of blogs and social networking sites, which has contributed to an explosion in the total number of Web pages in recent years. Sheer volume and churn of content has been further exacerbated by an increase in password-protected and dynamically generated content to overwhelm the legacy approaches to Web content categorization, which were developed to address a Web with a relatively small number of static, well-linked sites.
- With approximately 45 billion Web pages overall and 32 million new domains being added yearly, the percentage of Web that is dark is expected to grow exponentially over time. A new approach, based on effective real-time categorization, is required if acceptable use is to regain its efficacy in a Web 2.0 world.
