Control Excessive Bandwidth Consumption with Wavecrest Filtering and Reporting

Bandwidth consumption is an increasing concern for all organizations as bandwidth-intensive sites and video streaming become more popular.  The table below offers several examples of the amount of bandwidth that different online activities consume.

Activity or File Size (in kb)
One hour of IM chatting with AOL 10
Send a one-page text email with Gmail 150
View five different articles in Wikipedia 1,200
Upload a 10MP JPEG photo in Flickr 2,400
Downloading a 3 minute song from iTunes 5,600
Watch a 5 minute YouTube video 12,500
Watch episode of “The Simpsons” 25,000
Listen to one hour of music on Pandora 56,300
Compressed version of “Crouching Tiger, Hidden Dragon” 800,000

As the table shows, many online activities that are probably not work related utilize a lot of bandwidth.  The last thing any organization needs is network latency or slowdowns due to non-work related online activity.

To mitigate this problem, CyBlock and Cyfin provide IT with the information needed to determine 1) if the bandwidth consumption is work related and 2) if any measures need to be taken to reduce the amount of consumption.  Both products provide quantified data (via Web-use reports) that can help IT personnel keep track of network (bandwidth) utilization by users as well as by type of usage (appropriate or not so appropriate).

The Dashboard is the easiest way to get a quick view of bandwidth usage.  You can quickly find the top bandwidth consumers by users, groups, categories or sites.  You can also check when spikes in bandwidth activity occur.

The reports below can also be used to monitor bandwidth usage by users and identify potentially troublesome sites.

  • Site Analysis Bandwidth Report – Focusing on kilobytes by classification, category, and users, this report gives a good overview of whether the majority of bandwidth consumption was acceptable and which categories and users used the most bandwidth.
  • Top Bandwidth Sites Report – This report shows the top bandwidth consuming sites and their categories for the specified time period.
  • Network Information Report – Find out your busiest time of day for Internet use with this report.  It shows visits and kilobytes read by hour.
  • Top Users Report – This report displays the top hits, visits, and kilobytes by user.

These reports can help you anticipate overload possibilities and the need (or lack of need) to purchase additional capacity.  If abuse can be detected and brought under control, the cost of additional capacity may be avoided.

By monitoring and using the reports listed above, you can:

  1. Obtain an accurate, content-categorized picture of network usage patterns
  2. Identify bandwidth abusers for management attention
  3. Prevent bandwidth wastage through intelligent filtering
  4. Improve IT system performance and reduce bandwidth costs.

Web Filtering in the Workplace: Finding the Best Solution

There are many issues surrounding Web filtering in the workplace today.  Among them are whether to filter or not filter, and if you do filter, how strict should your policies be, what’s the best way to implement a Web filter, and what’s the best type of filter for your organization?  Wavecrest Computing attempts to answer these questions and more in our latest white paper, “Web Filtering in the Workplace: Finding the Best Solution.”  This paper discusses some of the issues surrounding Web filtering today, the different types of Web filters, and how Wavecrest approaches filtering with its RealTimePlus Filtering technology.

White Paper: Web Filtering in the Workplace: Finding the Best Solution

Facebook Surpasses Google As Most Visited Site

According to Hitwise research, Facebook recently passed Google as the top US site visited .  Traffic to both Facebook and Google make up a little over 14% of US website visits.

In your CyBlock or Cyfin product, Facebook is located in the Social Networking category, and you will find Google in the Search Engines category.  If you ever want to monitor these sites more closely, or any other sites for that matter, you can always place them in a custom category.

For more information on social networking in the workplace, read our white paper, “Social Networking or Social Not-Working?”. This white paper will help you determine if you need to block social networking at your workplace.

Stop A Pornography Surfing Problem Before It Starts: Why Monitoring Is Important

USA Today reported today that “several top Security and Exchange Commission staffers surfed porn sites as economy teetered.”  While many of us like to think that “everyone” knows it’s inappropriate to surf porn at work using the office computer, time and time again stories like these still pop up.  While whether or not to allow social networking in the office and how to control the use of these sites seems to be the big surfing topic today, apparently we still cannot forget about pornography.  Pornography poses several risks to businesses and government agencies. These include productivity losses, security issues and legal liability.  No matter how strict or lenient your acceptable use policy is, one thing is clear.  Communicating your Web-use policy and regularly monitoring employees’ Web use is important.  You want to stop the problem before it starts or turns into an employee spending “up to eight hours a day looking at and downloading pornography.”

Set Your Block Policies For Newly Released Categories

The new categories released and updated in your product on April 3 are set to “Allow” by default (for all CyBlock products).  This means that you will need to review these new categories and set your policy to “Block” those categories for which you want to restrict access.  Set your block policies at the Advanced Settings – Filter Settings – Block Web Categories screen.

For reporting and monitoring purposes, you may also want to change the new category’s classification statuses at the Advanced Settings – Category Setup – Classification screen to match your organization’s Acceptable Use Policy.

See the Category Update Data Sheet for a full list of categories and their descriptions.

Enforce Safe Search in Google, Yahoo and Bing with CyBlock

If you haven’t already done so, check out the safe search feature in your CyBlock Proxy, CyBlock Appliance or CyBlock ISA product. With this feature, you can force Google, Yahoo and Bing to strictly use Safe Search. To enable it, go to the Advanced Settings – Filter Settings – Safe Search screen, check the enable box and hit Submit. When enabled, the product will reset search engines to “safe search” even if users change the preference in the search engine. This will block Web pages containing explicit sexual content from appearing in search results.

Note: Safe Search is available only in Versions 6.0.0 and later.

New Categories Coming April 3!

New categories and category changes will automatically be updated in your product on April 3, 2010 for CyBlock Versions 6.0.0 and later or Cyfin Versions 8.0.0 and later.  If you do not have these versions of the product, you will need to upgrade to the most current version in order to get the new categories and category changes.

For CyBlock, these categories will be allowed by default. Therefore, you will need to go to your Advanced Settings – Filter Settings – Block Web Categories screen and alter your policies.  For reporting and monitoring purposes, you may also want to change the new category’s classification statuses at the Advanced Settings – Category Setup – Classification screen to match your organization’s Acceptable Use Policy.

See the Category Update Data Sheet for a full list of categories and their descriptions.
