Computers: Wireless Network Security

Wireless Network Security

Written by Lawrence Andrews

Working from home has its advantages, including no commute, a more flexible work schedule and fresh coffee and home-cooked meals whenever you want.

But working from home while using a wireless local area network (WLAN) may lead to theft of sensitive information and hacker or virus infiltration unless proper measures are taken. As WLANs send information over radio waves, someone with a receiver in your area could be picking up repparttar transmission, thus gaining access to your computer.

They could load viruses on to your laptop which could be transferred to repparttar 147700 company's network when you go back to work.

Up to 75 per cent of WLAN users do not have standard security features installed, while 20 per cent are left completely open as default configurations are not secured, but made for repparttar 147701 users to have their network up and running ASAP.

It is recommended that wireless router/access point setup be always done though a wired client.

Change default administrative password on wireless router/access point to a secured password.

Enable at least 128-bit WEP encryption on both card and access point. Change your WEP keys periodically. If equipment does not support at least 128-bit WEP encryption, consider replacing it.

Although there are security issues with WEP, it represents minimum level of security, and it should be enabled.

Change repparttar 147702 default SSID on your router/access point to a hard to guess name. Setup your computer device to connect to this SSID by default.

Setup router/access point not to broadcast repparttar 147703 SSID. The same SSID needs to be setup on repparttar 147704 client side manually. This feature may not be available on all equipment.

Darknet's The Black holes Of The Internet

Black Holes & Darknet's

------------

A “Black Hole” can be defined many ways. One definition is “An area of space-time with a gravitational field so intense that its escape velocity is equal to or exceeds repparttar 147589 speed of light”, another is “A great void or abyss”, and yet another and more relevant definition is “What data has fallen into if it disappears mysteriously between its origin and destination sites” For instance, an e-mail that never reaches it’s destination and repparttar 147590 sender never receives a bounce or undeliverable message.

Darknet's - The Internet – A Million Points Of Light

------------

Just for a moment, try to visualize repparttar 147591 Internet like a clear night sky with millions of stars. Some stars are dim while others are bright, and others appears to blink on an off. Now turn your attention to what you “don’t” see. What appears to be repparttar 147592 black spaces between stars in repparttar 147593 night sky. In many cases, there are stars there, just to faint to see with repparttar 147594 naked eye. However, great voids of darkness could be repparttar 147595 result of a black hole, an area of space where nothing that goes in, not even light, can escape.

There are places like this on repparttar 147596 Internet. Some are there by accident, maybe through repparttar 147597 incorrect configuration of a router or group of Internet hosts. But there are those areas of Internet dark space that are there quite on purpose. Darknet’s, unlike honey nets or honey pots, where malicious activity can be monitored and recorded, appear as black holes in repparttar 147598 Internet address space. Any data, communications, or request that falls into a Darknet is lost for ever. The sending host never receives a response.
