ComGuard warns wireless LAN users to reinforce security

According to regional security consultants, ComGuard, organisations that have rolled out WLANs need to review existing security policies and procedures.

Local companies must take steps to secure their wireless local area networks (WLANs). According to regional security consultants, ComGuard, organisations that have rolled out WLANs need to review existing security policies and procedures.“There’s no doubt that WLANs provide extra flexibility for companies in the region,” says Daniel Nufer, regional sales director for ComGuard. “However, it’s essential that companies don’t sacrifice system integrity for convenience. Radio waves can be monitored by outside agencies, which means that a determined hacker can discover your confidential information or disrupt the operation of your network,” he adds.There are various ways that hackers can access information transmitted through WLANs. The tools required to take advantage of the weaknesses of radio frequency (RF) networks are readily available.ComGuard is advising local companies to conduct a security survey of their respective network infrastructure to identify potential weak spots. Organisations should also install technology to detect possible intrusions and conduct regular sweeps for unauthorised signals and devices.“Companies in the Middle East can enjoy the benefits provided by wireless networks and be confident about the security of their data, provided they are aware of the dangers and take positive steps to deal with them,” says Nufer.“The problem is that too many people believe that information transmitted on WLANs is safe and so they don’t apply reliable security measures. The sooner companies take action on this issue, the more confident they and their customers can be,” he adds.
