Wireless internet connection problems validating identity

Since most 21st-century laptop PCs have wireless networking built in (see Intel "Centrino" technology), they don't need a third-party adapter such as a PCMCIA Card or USB dongle.Built-in wireless networking might be enabled by default, without the owner realizing it, thus broadcasting the laptop's accessibility to any computer nearby.Hence, it is important to understand the characteristics of such applications and evaluate the vulnerabilities bearing the highest risk in this context.

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.

Such security breaches have become important concerns for both enterprise and home networks.

If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot.

Hackers have found wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.

The risks to users of wireless technology have increased as the service has become more popular.

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.

However, lack of knowledge among users about the security issues inherent in setting up such systems often may allow others nearby access to the connection.

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.
