Review - Intego Content Barrier
by Michael Flaminio
5.23.01
Content Barrier from Intego is an Internet
protection utility. The software is ideally suited to monitor and restrict access
of Internet content by children. The software can also be deployed in the workplace
to keep employees from loafing off on the job. Content Barrier operates by monitoring
and/or blocking predefined Internet content from entering or leaving a computer.
Internet Filtering
About five or six years ago protecting children from the Internet was a hot button
topic. The issue is still alive today, but the surrounding sensational hype has been toned
down. Never the less, the Internet still has plenty of unsightly things to be found.
Internet filtering has two schools of thought. First you can filter predefined undesirable
content, and second you can only allow known appropriate content. Most people use
filters to block content based on predefined variables or just restrict access to
specific sites. Trying to successfully block inappropriate content presents a constantly
moving target. The filters try to walk a fine line of blocking what appears to be
bad, while not over doing things by blocking content that doesn't need to be blocked.
Functions
Content Barrier includes multiple preset filters designed to block out common undesirable
types of content. With a click of a button, Content Barrier can block access to content
such as sex and gambling related sites in addition to services such as chat and email.
Users can also create custom filters for specific items not covered in the built-in
filers. In the event a site gets inappropriately blocked, Content Barrier allows
users to set overrides for specific sites.
Content Barrier works by simply monitoring network activity. If a user tries to do
something the software is configured to prohibit, Content Barrier will intercept
the network traffic. In the case of Web browsing, the software will display a blank
Web page with a blocked notification. The software even works for framed Web pages,
which will block specific frames if prohibited content is detected.
Other filtering features include time based filters, which can restrict/allow access
during specified times, and also an "anti-predator" feature, which monitors
specific text transmissions. Example uses for these features can include restricting
access to the Internet while a parent is at work, or prohibiting users from transmitting
sensitive data such as phone numbers or credit card info. Personally, the time filters
and anti-predator features didn't seem to work as I expected. Regardless of my settings
I couldn't get the these two features to what I thought they should.
Multiple Users
Content Barrier also allows multiple users. So say for example if multiple children
use the same computer, each individual can have a separate filtering setting. When
using accounts, users log in an out through the Content Barrier software. This can
be helpful if say for example children of varying ages can have access to different
type of information.
Also available is password protection. Using password protection, users will be prompted
to enter a password when Internet software first starts up. The can be a basic setting
to ensure that individuals are using the correct access settings. Another option
is to ensure that the Internet is only being used when someone with the password
is present.
Logging
Probably the most useful feature of Content Barrier is its logging. The log features
allow users to monitor activity, which may be sufficient in most Internet access
situations. The software can be configured to monitor specific activities or just
monitor everything. The software can output logs as files or as email for all accessed
sites or only flagged activity. Content Barrier also has an interesting overall stats,
showing how many sites have been accessed, filtered and blocked.
One feature I'd like is to see greater detail in the logs. The logs will tell you
what site was blocked, but I think it would be helpful to know why a site was blocked.
This may help to manage the software's configuration in addition to keeping a better
eye on what's going on.
Security
Content Barrier isn't an absolute solution. For those savvy enough to understand
the Mac OS, users can fairly easily bypass the utility. Perhaps Content Barrier would
be best used with the Mac OS's built in multiple user security. This would limit
how individual users would be able to access the Mac OS system software, limiting
their ability to disable the software.
In the end, I don't think the idea of Content Barrier is to be the ultimate user
security software. It only operates for the Internet. If you wish to block total
access or total Internet access, then the Mac OS's multi-user security is your best
bet. What Content Barrier does is to allow users access to both the computer and
Internet while also controlling what happens on the Internet.
Wrap-up
Content Barrier is a pretty good piece of software, but it's not the end all-be all
of keeping evil out of your computer. It functions merely as a tool to be used with
other protective measures.
Content Barrier is currently available for Mac
OS 8.1 or later. Mac OS multi-user security functions will require Mac OS 9 or later.
Intego states that a Mac OS X version will be available during the third quarter
of 2001. Content Barrier retails for $39.95.
