Wireless Security


									Wireless Security
When using a wireless system, there are countless security concerns to be
aware of, many of which require the system to be patched regularly to
keep it up to date. Patches should be applied to both the operating
systems and the applications, or the system will still be vulnerable.
Keeping your wireless system patched gives hackers few places to get
inside as well as warding off the new types of attacks that are being
developed. While security patching is of the utmost importance, few
companies are offering information about the security that is needed for
wireless systems.
One of the threats that wireless users face is MAC spoofing. There are
programs that allow hackers to "sniff" the traffic on the network and
find MAC addresses that have privileges on wireless networks. This allows
the sniffers to get through the MAC filtering systems that allow specific
MACs to get that access. By using software that allows their own computer
to pretend it has the MAC address it has sniffed out, it then has the
same access to the network.
Another threat to wireless data is using WEP, which is notoriously easy
to crack. WEP is an attempt to give wireless networks the same kind of
encryption that a wired system has. The encryption, however, is not as
secure as most people believe. The encryption is flawed and can be hacked
within minutes. It's often the subject of hacking attempts both for its
ease and because it's been around so long that just about any wireless
device supports it.
To get a better level of protection, use WPA2 instead. WPA2 adds a much
stronger layer of protection to your wireless security than by simply
using WEP. In its second generation, provides more than just encryption-
it also provides a controlled access entry. Using the network requires
the use of a lengthy password that is unlikely to be hacked. The
passwords to gain access can be up to 63 characters, making it easy to
come up with one that will be virtually impenetrable. Of course, this is
dependent on using a unique password that has never been found in any
printed or online work.
If you use a wireless system often, leaving it running at all times to
keep it available can be tempting. But, keeping the broadcast running
around the clock only increases the amount of time it can be the object
of an attack. If you turn off the network at times when you won't be
using it, you can remove some of its vulnerable time.
Using the system out of the box without implementing these strategies
leaves it unsecured and vulnerable. If you run your system with WPA2,
choosing a long password, and couple that with running the system only
when it's needed and patch your system often, you have a much better
chance of keeping your system from being hacked. And if the system does
come under attack, have an intrusion detection device in place. The
standard products used for wired networks don't always translate into the
same service for wireless ones, so use one that is specifically for
wireless networks.
