Wireless networks security issues


Wireless networks security issues

Wireless local areas networks (WLANs), which transmit and receive data over radio waves, are more efficient than wires. WLANs can be hacked, unlawful interception Wireless networks security and eavesdropping because there is no physical barrier.

Wireless network security threats and issues

Three of the most prevalent WLAN security threats are:

  • Denialofservice attacks – where an intruder floods the network using messages to affect the availability and use of network resources
  • Session Hoaxing and Spoofing – where an attacker can gain access to network resources and data by pretending to be a valid user
  • Data Eavesdropping – when unauthorised third party intercept data being sent over the secure network

These threats can be countered by making sure your WLAN is correctly configured. Enable a variety security features such standard authentication and encryption along with access control mechanisms.

Basic WLAN security features

An early WLAN hardware utilized a number basic security methods including

  • Service set Identifiers (SSIDs), prevents access point connection unless the device correctly uses the given identifier.
  • Media Access Control – This is where addresses are attached to each device to limit access points.
  • Wired Equivalent Privacy, (WEP)WEP uses encryption keys to make sure that only devices with correct keys can communicate with access points

WEP can still be found in many devices. Users have discovered compatibility issues with new equipment. WEP has not been shown to be effective against hackers. It is a good idea to upgrade any devices that depend on this technology.

Even with all of these security features, basic WLAN features can’t guarantee your network will be secure. WLAN equipment comes often with security measures that are completely disabled. You have no security if you don’t turn these on.

Upgrade your WLAN security protocols

These security features are essential for WLANs that rely only on them. It is important that they work correctly. It is preferable to upgrade to more recent security methods such as Wi-Fi protected Access (WPA) or WPA2.
