Common Security Threats in WLAN

WLANs are vulnerable to several security threats, including unauthorized access, eavesdropping, and denial-of-service (DoS) attacks. Hackers can exploit weak passwords or outdated encryption protocols to gain access to the network. Eavesdropping allows attackers to intercept data transmitted over the network, while DoS attacks disrupt the network’s functionality.

Key Security Protocols

To enhance WLAN security, various protocols are implemented. Wired Equivalent Privacy (WEP) was an early standard but is now considered insecure due to vulnerabilities. Wi-Fi Protected Access (WPA) and WPA2 are more advanced protocols that use stronger encryption methods. WPA3, the latest standard, offers enhanced security features such as individualized data encryption and protection against brute-force attacks.

Best Practices for Securing WLAN

Securing a WLAN involves implementing best practices like changing default SSIDs and passwords, enabling network encryption, and using strong, unique passwords. Disabling SSID broadcasting can make the network less visible to attackers. Employing firewalls, intrusion detection systems, and virtual private networks (VPNs) further enhances security. Regularly updating firmware and monitoring network activity are also essential to address vulnerabilities promptly.
