Wireless Network Security

Wireless network security refers to the protection of wireless networks from unauthorized access, attacks, and other security threats. Wireless networks, also known as Wi-Fi networks, use radio waves to transmit data between devices, which makes them vulnerable to various types of cyber attacks.

Subfields of Wireless Network Security

• Wireless encryption: a method of encrypting data transmitted over wireless networks to prevent unauthorized access. The most commonly used wireless encryption protocol is Wi-Fi Protected Access II (WPA2), which uses advanced encryption standard (AES) encryption.
  
  
• Wireless access control: a set of procedures and technologies used to restrict access to wireless networks to authorized users and devices. This includes implementing strong authentication mechanisms, such as using strong passwords or multifactor authentication, and limiting access to sensitive data.
  
  
• Wireless intrusion prevention system (WIPS): a security system that monitors wireless networks for unauthorized access, attacks, and other security threats. WIPS can detect and prevent a variety of attacks, such as rogue access points, denial-of-service (DoS) attacks, and man-in-the-middle attacks.
  
  
• Wireless network segmentation: the practice of dividing a wireless network into smaller, isolated segments to reduce the risk of unauthorized access and contain potential security breaches. This includes using firewalls and other security devices to control traffic between different segments.
  
  
• Wireless security policies: a set of guidelines and procedures that govern the use of wireless networks and devices within an organization. This includes establishing rules for password strength, data encryption, device management, and other security-related issues.
