With the vast majority of desktop and laptop
PCs now featuring various disk writers and high-speed data ports, it has
never been easier for a user to deliberately or accidentally remove
sensitive data, introduce malicious code or transfer inappropriate content.
To guard against
these risks, DeviceWall actively manages the connections that can be used
to transfer data to and from the PC, such as;
- USB Ports
- Firewire Ports
- Internal & external floppy drives
- Internal & external CD and DVD drives
DeviceWall simplifies the
task of controlling which devices can be connected to a PC by grouping
them into the following classifications;
- Storage Devices
- Diskette drive
- Plug and play storage
(includes: USB memorySticks, iPods & media players, CompactFlash,
Cameras etc)
- PDAs
- MS pocket CE (includes: iPAQ,
AXIM etc)
- Blackberry (and other RIM devices)
- Palm OS devices (includes Zire, Tungsten and Treo phones etc.)
- Optical drive
- DVD/CD ROM (includes internal
& external drives / writers
Calculating the risk
When deciding what devices pose the greatest risk to your organization,
you need to understand the capacity of the device, how accessible they are
and how widespread their use is; |

Organizations also need to determine what
are the legitimate reasons why certain individuals may need access to any
specific type of device. Once you know these exceptions you should quite
simply block all other scenarios from occurring.
Determine your permissible
use policy and then isolate your company from the accidental or malicious
use for the rest. By controlling access to these devices and more,
DeviceWall will substantially reduce the security risk of non company
devices interfacing with your network. |
