How Much Personal Internet Surfing in the Workplace is Too Much?

Leave a reply

It depends on what your organization considers “acceptable.” Research shows that the average person spends around one hour per day on non-work related internet surfing.   It also shows that the majority of viruses enter via Internet surfing.

Wavecrest’s Cyfin and CyBlock products are configurable to fit your organization’s acceptable use policy. You can set acceptability ratings and visit thresholds to each category.  To set acceptability ratings, go to the Advanced Settings – Category Settings – Classification screen in your product.

With CyBlock you can select to “block” or “allow” each category and configure blocking by hour on the Advanced Settings – Filter Settings – Block Web Categories screen.  You can also configure real-time filtering with our deep packet analysis for content types and file extensions on the Advanced Settings – Filter Settings – Block Web Content screen in your CyBlock product.

Wavecrest’s RealTimePlus Filtering

Leave a reply

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.
