At Network Box, one of the most common questions we’re asked by IT directors and managers is how to protect wireless networks. Obviously, there are many security technologies on the market that are capable of securing wireless networks; but what businesses – and home users – don’t appear to understand is that they can greatly increase the security of their wireless networks simply by switching protocols from wired equivalent privacy (WEP) to wi-fi protected access (WPA).

The continual success of the network security industry is only as effective as the security professionals that run it. This means recruiting high-calibre security professionals is essential for any organisation wishing to be protected from the external and internal threats. Identifying, training and retaining security personnel is hard, often proving to be a time-consuming and expensive process.

In late 2006, an old technique became popular again with the blackhats. They resurrected parasitic malware, a technique whereby malware is added to existing files on a system.

So what can a company do to protect itself from this form of attack?

Senior managers outside the IT department will most likely have a very hazy impression of what is meant by the terms blogging, iTunes, MySpace or MSN messenger. Yet the use of these new technologies at work is a major threat to their businesses.

Guidelines for companies on creating policies around employees’ access to social networking sites, such as Facebook, during work hours

The era when script kiddies were the primary online threat has long since passed. Today, hacking and malicious code are big business. Too big, it would seem, for some blackhats to manage single handed.
