Cyber Security Suite

The operation and management of an enterprise is becoming increasingly dependent on
electronic information flow. An accompanying concern becomes the security of the
communication infrastructure and the security of the data itself. The following table profiles
security risks and how the TranSphere TS Wireless provides a solution for minimizing
vulnerability.

Security Risk

The TranSphere TS Wireless Solution

Unauthorized access to the backbone

network through a foreign remote

radio

▪

Approved Remotes List

Only radios on the Approved Remotes list connect

“Rogue” AP, where a foreign AP

takes control of some or all Remote

radios and thus remote devices

▪

Approved AP List

A Remote connects only to APs on its Approved AP

List

“Dictionary attacks”, where an intruder

runs a program that sequentially tries

to break a password

▪

Failed log-in lockdown

After three tries, a transceiver ignores log-in

requests for five minutes. Critical event reports

(traps) are generated as well.

Denial of service, where Remote

radios could be reconfigured with bad

parameters, bringing the network

down

▪

Remote log-in

▪

Local console log-in

▪

HTTP (Hypertext Transfer Protocol) and Telnet

disabled, enabling only local management

▪

services

Airsnort and other war-driving

intruders in parking lots, near

buildings, etc.

▪

Frequency-hopping spread spectrum (FHSS) does

not talk over the air with standard 802.11b cards

▪

The transceiver cannot be put in a “promiscuous”

mode

▪

Proprietary data framing

Eavesdropping, intercepting

messages

▪

128-bit encryption

Key cracking

▪

Automatic Key Rotation algorithm. In addition, a

Force Key Rotation command is available to

immediately rotate the keys of the AP and

synchronize all Remotes with it.

Replaying messages

▪

128-bit encryption with rotating keys

Unprotected access to configuration

via SNMP

▪

Non-secure SNMP versions can be SNMP enabled

or disabled at will.

▪

NMPv3 password protection

Potential, ongoing attacks

▪

Provides early warning via SNMP through critical

event reports of unauthorized log-in attempts and

suspicious activities
