Wireless Security
NJ
NJ Locksmith & Security is the complete source for all of your home
and business security systems.
Wireless Security cameras transmit to a receiver over a high frequency radio
signal and Connect the receiver to a video monitor or recorder for live viewing
or recording.
You can even connect these cameras to an internet connected dvr.
Can you imagine making wireless networking more secure - while at the same time
making it easier to set up?
two primary Wireless Security issues:
* Access - making sure that only authorized people can use the wireless network.
Without proper access control anyone in the vicinity of the building can use the
wireless network, and thus get access to RU-net.
* Privacy - making sure that no one can watch your communications. Without this,
anyone any the vicinity of the building can watch everything you do on a
wireless network. This will let them steal your passwords and look at everything
you are doing.
There are two approaches commonly used at Rutgers:
1. WPA or possibly WEP for access control and some level of privacy;
supplemented by end to end encryption for privacy
2. End to end encryption (typically SSL) for privacy, and special gateway
systems for access control (see below)
By Wikipedia:
Wireless security is the prevention of unauthorized access or damage to
computers using wireless networks.
Wireless networks are very common, both for organizations and individuals. Many
laptop computers have wireless cards pre-installed. The ability to enter a
network while mobile has great benefits. However, wireless networking has many
security issues. Hackers have found wireless networks relatively easy to break
into, and even use wireless technology to crack into wired networks.
The risks to users of wireless technology have increased as the service has
become more popular. There were relatively few dangers when wireless technology
was first introduced. Crackers had not yet had time to latch on to the new
technology and wireless was not commonly found in the work place. However, there
are a great number of Wireless Security risks associated with the current
wireless protocols and encryption methods, and in the carelessness and ignorance
that exists at the user and corporate IT level. Cracking methods have become
much more sophisticated and innovative with wireless. Cracking has also become
much easier and more accessible with easy-to-use Windows-based and Linux-based
tools being made available on the web at no charge.
Some organizations that have no wireless access points installed do not feel
that they need to address wireless security concerns. In-Stat MDR and META Group
have estimated that 95% of all corporate laptop computers that were planned to
be purchased in 2005 were equipped with wireless. Issues can arise in a
supposedly non-wireless organization when a wireless laptop is plugged into the
corporate network. A cracker could sit out in the parking lot and break in
through the wireless card on a laptop and gain access to the wired network.
