Wireless networks are somewhat less secure that wired networks, because of the fact that one can easier access the network if he is in the coverage area of the access points. Of course, there are various barriers in any wireless network that from the so called basic security which can stop the unintended access of persons that are foreign to the network and that are simply situated in the coverage area. But when it comes to a trained hacker that wants to access that network, these basic defenses won't give them too many headaches.

The security methods that have been provided to wifi networks assure a rather low security level, and this is why additional security measures must be taken. In June 2004, a new wireless standard named 802.11i has been approved, and this standard does improve wireless security. The basic wireless security is assured by the following included functions:

- SSID
- WEP
- Media Access Control

SSID is a code that defines the belonging to a certain access point of a wireless network. All wireless devices that want to communicate through a network must have their own SSID, which will have the same value as the one found in the access points' setting in order to make a valid connection. Normally, an access point sends out its SSID every couple of seconds. This way of operating can be stopped so that a person with bad intentions can not discover the SSID automatically and therefore the access point. But, because SSID is included in every wireless sequence's beacon, it is very easy to detect if someone has monitoring equipments that a
