The seizure of £38m worth of counterfeit Cisco equipment
has raised concerns over the security of networks.
Last week the US Department of Justice and Department of
Homeland Security
seized more than 400 counterfeit Cisco network hardware and
labels with an estimated retail value of more than £38m.
The equipment included counterfeit network hardware, in
particular network routers, switches, network cards and modules
manufactured by Cisco. Assistant Attorney General Alice Fisher of
the Criminal Division, said, "It is critically important that
network administrators in both private sector and government
perform due diligence in order to prevent counterfeit hardware from
being installed on their networks."
Penetration testing specialist, SecureTest warned that
government and communications networks could be infected with
malicious firmware imported from places in the Far East, such as
China. Unlike current malware, machine level hardware such as the
chipsets used in routers and switches and other computer devices
are rarely tested and may already have established back doors in
communications systems across the country, the company said.
SecureTest warned that the UK government would be unlikely to
spot the firmware-based malware because the existing accreditation
process did not cover switches, routers and other devices at a low
enough level. Ken Munro, managing director of SecureTest, says,
"Organisations should change their security policies and procedures
immediately. This is a very real loophole that needs closing.
Users looking to buy Cisco gear have very little guidance as to
how to spot fake Cisco equipment, as any attempt at publishing
guidance would simply alert the counterfeiters - who would then be
able to correct the differences between their products and the
genuine article.
In
one message board a network administrator suggested people
simply look at the price. "There are a lot of ways to spot fake
Cisco, with a too good to be true low price being the very first
one. However, it is too dangerous to 'publicly disclose' this
information as the counterfeiters will use it to 'correct' their
mistakes."
The problem for network administrators is that the counterfeit
network equipment is very good and so it can be difficult to spot
differences. A Cisco reseller commenting on an online message
thread about fake Cisco gear, said, "The fakes are very good, look
the same, work the same, running the real IOS (Cisco operating
system) it is amazing how good they are considering they are
fakesoften very high quality...but still nothing beats having
authentic gear with full support from Cisco."
UsedCisco.com has produced a guide that recommends, among other
things, that users avoid buying used Cisco gear from eBay and
direct from China, and that they check holograms and make sure
documentation is written in English, using the same font and
without spelling mistakes. In addition, serial numbers should be
checked against Cisco's database.
