What is War Driving?
War driving refers to the practice of searching for and mapping out wireless networks, specifically Wi-Fi networks, while driving or walking around an area. The term “war driving” is derived from “wardriving,” a more aggressive term associated with the act of intentionally seeking vulnerabilities in wireless networks.
Wireless LAN Security Measures
With the increasing popularity and widespread use of wireless networks, ensuring their security has become crucial. Here are some essential security measures to protect your wireless LAN:
1. Change the Default Admin Password
When setting up a wireless router or access point, always change the default administrative password. Most hackers are familiar with the default passwords, making it easier for them to gain unauthorized access. A strong and unique password will help safeguard your network.
2. Enable Network Encryption
To prevent unauthorized users from accessing your network, enable network encryption. The most common encryption protocols are Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2). These encryption methods provide a higher level of security than the older and less secure Wired Equivalent Privacy (WEP) protocol.
3. Hide the Network SSID
Wireless networks broadcast their Service Set Identifier (SSID), which acts as their name. By hiding the SSID, you can make your network less visible to potential attackers. However, keep in mind that this measure alone is not sufficient as skilled hackers can still discover hidden networks.
4. Enable MAC Address Filtering
To further enhance security, you can enable MAC address filtering. Every network device has a unique MAC address, and by specifying which devices are allowed to connect to your network, you can effectively block unauthorized access.
5. Regularly Update Firmware
Keep your wireless router or access point up to date by regularly installing firmware updates provided by the manufacturer. Updates often include security patches and bug fixes that can address vulnerabilities.
6. Enable Firewalls
Most modern routers come with built-in firewalls that provide an extra layer of protection. Activate the firewall functionality of your router to block potential threats from the internet.
7. Disable Remote Administration
To prevent outsiders from remotely accessing and controlling your router’s settings, disable the remote administration feature. This will limit access to the local network only.
By implementing these security measures, you can significantly reduce the risk of unauthorized access to your wireless LAN. Remember to constantly be aware of potential security threats and keep up with the latest best practices in wireless network security.
