Validating identity wireless router
Hacking has also become much easier and more accessible with easy-to-use Windows- or 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.
Such "piggybacking" is usually achieved without the wireless network operator's knowledge; it may even be without the knowledge of the intruding user if their computer automatically selects a nearby unsecured wireless network to use as an access point. If an employee (trusted entity) brings in a wireless router and plugs it into an unsecured switchport, the entire network can be exposed to anyone within range of the signals.
Many laptop computers have wireless cards pre-installed.However, there are effective countermeasures (like disabling open switchports during switch configuration and VLAN configuration to limit network access) that are available to protect both the network and the information it contains, but such countermeasures must be applied uniformly to all network devices.Due to its availability and low cost, the use of wireless communication technologies increases in domains beyond the originally intended usage areas, e.g. Such industrial applications often have specific security requirements.WEP is an old IEEE 802.11 standard from 1999, which was outdated in 2003 by WPA, or Wi-Fi Protected Access.
WPA was a quick alternative to improve security over WEP.
Modern operating systems such as Linux, mac OS, or Microsoft Windows make it fairly easy to set up a PC as a wireless LAN "base station" using Internet Connection Sharing, thus allowing all the PCs in the home to access the Internet through the "base" PC.
