guys,
(on the usb)
last year, we had a seminar from a gfi partner on their new product
that can control removable media (usb thumb drives/mp3, firewire,
floppies, cd) via AD.
here's the link:
features:
How it works
To control access, GFI LANguard P.S.C. installs a small footprint
agent on the machine. This agent is only 1.2MB in size – the user will
never know it is there. GFI LANguard P.S.C. includes a remote
deployment tool, allowing you to deploy the agent to hundreds of
machines with just a few clicks. After installation, the agent queries
Active Directory when the user logs on and sets permissions to
removable storage accordingly. If the user is not a member of a group
that allows him/her access, then access to the device/CD/floppy is
blocked.
Controls access to all types of USB sticks, SD cards (digital cameras) and more
USB sticks are one of the main threats as they are small, easily
hidden and can store up to 1GB of data. GFI LANguard P.S.C. recognizes
all USB sticks. In addition, it can control access to any device that
can be mounted as a hard disk (whether accessed via USB, FireWire,
etc.). For example, plugging a digital camera into a USB port gives
users access to storage on an SD card; SD cards are available in
several sizes including 512MB and over.
Controls access to CDs and floppies
You can centrally disable users from reading or writing data to/from a
CD or floppy. This way, you can block normal users from bringing in
data that could be harmful to your network, such as viruses, Trojans
and other malware. Although you can switch off CD and/or floppy access
from the BIOS, in reality this solution is impractical: You would have
to physically visit the machine to temporarily switch off protection
and install software. In addition, advanced users can hack the BIOS.
Easily configure users who can have access via Active Directory
To grant a user access to any one or all three types of devices,
simply make that user a member of pre-defined Active Directory groups
for each of the three kinds of devices. You can also leverage the
power of groups and make an entire department a member of the group.
Other storage control software requires cumbersome per-machine
administration, forcing you to make the changes on a per-machine basis
and update the configuration on each machine before the settings can
take effect. Configuration of GFI LANguard P.S.C. is effortless and
leverages the power of Active Directory.
Includes remote deployment tool
The GFI LANguard P.S.C. remote deployment tool can deploy the agent
network-wide in minutes. You can configure to deploy domain-wide, per
computer or to a list of computers.
Centralized control facilitates temporary access
Because you can easily add/remove a user to a group in Active
Directory, it is simple to grant temporary access to a removable
media, floppy or CD. Temporary access may be occasionally required,
but should not mean that you cannot control access the rest of the
time.
