EEMA – the independent, European non-profit association for e-Business

EEMA and Orthus highlight wireless security flaws

A recent live study of the wireless security networks operating in Zurich revealed that 79% of organisations using a Wireless Local Area Network (WLAN) are leaving their network wide open to security breaches from hackers.

The survey, conducted by Orthus, the information security solutions provider, for EEMA’s “It’s A Wireless World” workshop held last week in Zurich, highlighted that of the 193 networks identified, 79% were not using the established WEP encryption technology and 63% of the networks were easily identified by name.

The results reflect those found in similar studies carried out by Orthus in London, Milan, Berlin and Paris, (note to press: for the results of the previous four studies, please see the bottom of this release) all of which have proven that the frequencies, physical location and ownership of an organisation’s WLAN can easily be determined by inexperienced hackers from the emanations on the streets.

“What’s worse”, commented Richard Hollis, CEO at Orthus “is that even if companies do encrypt their network using the WEP technology, a recently- discovered flaw indicates that WEP is an fairly insecure encryption device in itself. Although WEP does use encryption technology, the strength of the algorithms has been compromised. Therefore, cracking the encryption used is relatively simple, taking a maximum of a couple of hours even on a heavily-used network. However, the fact that our four studies have shown that in 23% to 67% of cases, an organisation’s name can be easily identified by a hacker is also of great concern, and has nothing to do with whether or not the network is encrypted”.

Whilst organisations spend millions of euros securing their wired network infrastructure, the same considerations are often ignored when implementing a WLAN. The fact that an internal network is often linked to the WLAN is cause for concern, as poor implementation of the WLAN can seriously compromise the integrity of the whole network.

“The above issues will be addressed within EEMA’s forthcoming WLAN Best Practise Document with contributions from Orthus and other EEMA Members” commented the chair of EEMA’s wireless work group, Rick Chandler. The document will highlight the importance of securing a WLAN, the steps to take, and how to minimise any security breaches. Even with the WEP flaws, it is still possible for companies to secure their WLAN to an acceptable level by following a few basic principles, which will help to minimise intrusion into their main networks”. The Document will be made available in full to EEMA Members.
