How is ScreenShield™
Enterprise different from URL Filtering Software?
URL filters only restrict access to known pornographic web
sites. While these Web filters attempt to eliminate access
to known pornographic websites, ScreenShield™ Enterprise
protects users from any image displayed on a computer, regardless
of its source, detecting images from all sources including:
Internet, CD-ROM, DVD, hard drive, floppy disks, email messages,
embedded in documents and movies. Although the prime source
of illicit materials, the downloading of pictures from the
Internet is only one of many ways pornography is distributed,
displayed and circulated without detection.
How does ScreenShield™
Enterprise detect explicit images?
ScreenShield™ Enterprise's sophisticated, content-based,
detection engine scans the computer screen, analyzes displayed
images for skin tones, and checks for a range of criteria
that are typically associated with pornographic images.
What does ScreenShield™
Enterprise do when it detects explicit images?
When ScreenShield™ Enterprise detects pornographic content
displayed on a computer screen, it records the time and date of
the event, logs the Web site address, and captures a thumbnail image
of the computer screen. This information, plus the name of the user's
computer, is saved to a central log file. This process creates a
complete audit trail that management can use to enforce company
policy.
Can I customize ScreenShield™
Enterprise's monitoring levels?
You can customize ScreenShield™ Enterprise's monitoring
levels to suit your organization's requirements. ScreenShield™
Enterprise offers modes of operation that determine how a client
PC is monitored: Passive Mode, Active Warn Mode, and Active Lock
Mode.
In Passive mode, the system detects and monitors suspected pornographic
content silently. In Active Warn mode, the system displays a warning
message that advises users that they might be watching pornographic
content, which is not allowed in the organization's computer facilities.
The most sensitive mode of operation is Active Lock. Active Lock
blocks offending images immediately and locks the PC until a supervisor
reactivates the machine. Active Lock mode requires the most management
supervision. This extra supervision entails responding to calls
requesting supervisor help to unlock computer screens. These calls
often come from users not even remotely involved with surfing
porno sites.
The Active Lock mode is therefore not recommended for corporate,
government, or large enterprise use. You can manage your enterprise
networks very nicely by choosing either the Passive mode or the
Active Warn mode. Active Lock is ideal in situations where you
have young children surfing the Internet and strict supervision
is required. In this scenario, teachers or parents are at the
ready to unlock machines that could expose children to unwanted
words and images.
Can ScreenShield™
Enterprise block pornographic content from being displayed on
the PC screen?
ScreenShield™ Enterprise offers multiple options to prevent
pornographic content from being displayed on the PC screen. These
options allow you to set the level of protection that is right
for you.
For example, Active Lock Mode blocks offending images, locks
the machine, and logs the event in a central log file. The locked
machine can't be reactivated until a supervisor unlocks it. Active
Warn Mode detects offending images and sends a warning message
to the user when pornographic material is detected.
Will ScreenShield™
Enterprise flag images that are not explicit?
Depending on the threshold level you set for the system, ScreenShield™
Enterprise will flag images that are not explicit. This is because
the ScreenShield™ Enterprise's detection engine is designed
to identify flesh tones, and as flesh tones can appear in almost
any image, the system does its job and flags the image. However,
ScreenShield™ Enterprise applies advanced algorithms and analytics
to reduce this risk, so the incidence of unnecessary flagged images
is kept to a minimum. You can adjust the sensitivity threshold on
the Image Detection tab of the Profile Properties window to suit
your company policy.
Can simply having ScreenShield™
Enterprise installed on a computer serve as a deterrent?
Yes, because you can display a ScreenShield™ Enterprise icon
in the Windows Task Bar of each personal computer. This icon is
a visible and permanent reminder to users tempted to view pornographic
content.
How to scan the video and images on a specific PC?
ScreenShield™ Enterprise Remote Administration application
allows you to individually scan the hard drive of each client for
any videos and images present in the hard disk. Since the scan drive
process requires considerable system resources it is recommended
that the scan drive function is performed in non-peak hours.

1.
Open the Remote Administration Console.
2.
From the Display Panel, select the client PC you want to
scan.
3.
Right-click the highlighted icon. The context-sensitive
menu appears.
4.
Select "Start Scan Drives" and Click on your desired
scanning options.
How to customize your ScreenShield™
Enterprise acceptable use policy?
ScreenShield™ Enterprise enables the administrator to ensure
users are aware of the computer usage policy that the organization
might have in place. This is done by displaying a message when the
user logs on to the client PC.
To customize your ScreenShield acceptable use policy, do the
following:
1.
Open the Remote Administration Console.
2.
From the Main Menu, click Tools > ScreenShield Policy.
The ScreenShield Policy window will appear.
3.
Modify the Policy.
4.
If you want the policy to be shown upon logon to every machine
ScreenShield client is installed, check "show policy
on startup".
How to check which machines have terminated ScreenShield™
Enterprise Client without authorization?
To check status of offline machines, do the following:
1.
Open the Remote Administration Console.
2.
From the Main Menu, click Tools > Check Offline Machine
Status.
3.
The window will appear with list of any machines that have
illegally terminated , uninstalled ScreenShield client. Icon
at the Display Panel will also show an Alert for those machines.
ScreenShield™ Enterprise facilitates the upgrading of ScreenShield
Enterprise clients with the package provided by Guardware or your
vendor.
To update the client machines do the following:
1.
Open the Remote Administration Console.
2.
From the Display Panel, select the client PC(s) you want
to update.

appear. Specify the location of the client executable, which
can either be in the form of a file in a shared directory
or from a URL. On pressing the Update button ScreenShield
Enterprise will automatically install the new version of the
client on the selected client PCs.
