Wavecrest’s RealTimePlus Filtering

Thursday, January 28th, 2010

RealTimePlus is our customer-configurable three-layer filtering process. It uses three layers of screening based on: (1) custom categories, (2) the Wavecrest categorization (control) list and (3) a real-time deep packet analysis process.

1. Custom Categories (the “First Layer”). ‘Custom categories’ supplement the standard categories. This enables you to better identify and control your users’ Web activity.   For example, you can create a custom category to:

  • Serve as a “white list” that contains all sites to which visits are allowed (while blocking all others).
  • Track and possibly block access to ‘standard’ sites that are not in the Wavecrest URL List but are of special local interest or concern.
  • Serve as a “black list” that contains all sites to be blocked (while allowing access to all others).
  • Track (but not block) visits to internal servers (intranet sites) and/or partner sites.

You can add custom categories at the Advanced Settings – Category Setup – Custom Categories screen. Then use the Advanced Settings – Category Setup – Edit URLs screen to add sites into your custom categories.

2. The Wavecrest URL List (the “Second Layer”). To accurately identify and categorize the vast majority of visits, Wavecrest products use a large, mature categorization control list.  This ‘control’ list consists of 69 ‘standard’ content-identification categories that is updated daily with URLs from around the world.  We recommend that you download the list daily to get the best filtering and monitoring coverage.   You can setup an automatic daily download of the list at the Administration – URL List – Schedule screen.

Another great customization feature with the control list is that you can add and move URLs in the standard categories.  For example, if you use Twitter as a Marketing tool but want to continue to block all other social networking sites, you can simply add www.twitter.com to the Marketing category.  You can make this change at the Advanced Settings – Category Setup – Edit URLs screen.

Finally, set your block/allow policies for your custom categories and standard categories at the Advanced Settings – Filtering Settings – Block Web Categories screen.

3. Deep Packet Analysis (the “Third Layer”). Using real-time ‘deep packet analysis,’ CyBlock can determine if the content of a URL is Flash, video streaming, audio streaming, images, Active X and more.  Any or all of these could be considered “inappropriate” and can be blocked.  You can also add your own extensions to be blocked.  You can block these types of content or add your own at the Advanced Settings – Filter Settings – Block Web Content screen.

Other Features

1. Hourly Blocking. You can block or allow categories at specific hours during the day.  For example, you may want to allow access to some categories during the lunch hour. You can set these hourly policies by clicking on the clock icon at the Block Web Categories screen.

2. Customizable Blocking Message. CyBlock comes with a standard blocking message, but you can configure the product to point to your own Web policy or personalized blocking message.  You can set this custom message at the Advanced Settings – Filter Settings – Web Blocking Message screen.

2008 Summer Olympics: Bandwidth and Productivity Concerns for Businesses

Tuesday, August 5th, 2008

The start of the 2008 Summer Olympic Games are right around the corner, and this year, NBC plans to stream 2,200 hours of live events on NBCOlympics.com.  This may cause several network problems and productivity losses for businesses. To give you an idea of how much bandwidth a video can eat up, an episode of “The Simpsons” uses about 25,000 kb.  This can cause major problems when you multiply that by several employees at one time. 

Whether you’re concerned about productivity, bandwidth or both, your CyBlock or Cyfin application can be used to help you filter and/or track Web access the NBC Olympics site. The site http://www.nbcolympics.com is included in the category Sports but can also be filtered or monitored separately by placing it in a custom category if you don’t want to block the entire Sports category.  Or, you can choose to just block video from the Web site by placing the URL http://www.nbcolympics.com/video/index.html in a custom category.  Dont’ forget that you can also use the hourly blocking option if you want to allow employees access to the site during lunch and after hours.

To use custom categories, simply go to Advanced Settings – Category Setup – Edit URLs.  Simply select the custom category you’d like to use, and type in the URL(s) you’d like to filter or monitor.  For Cyfin users and those that decide to just monitor Web use of NBCOlympics.com, you can run a Category Audit Report on the Custom Category that you created to track that site.
