Wireless Security

Wireless security encompasses the strategies and technologies used to protect wireless networks from unauthorized access and attacks. As wireless communications have become ubiquitous in modern society, the importance of robust security measures has grown exponentially.

Core Components

Authentication

• Access Control mechanisms to verify user identities
• Digital Certificates for validating network legitimacy
• Multi-factor Authentication systems for enhanced protection

Encryption

• WPA3 (Wi-Fi Protected Access 3) - current gold standard
• AES encryption for data protection
• End-to-end Encryption implementations

Common Threats

Wireless networks face numerous security challenges:

1. Man-in-the-Middle Attacks

   • Network Spoofing
   • Evil Twin Attacks
   • Traffic interception

2. Password-Based Attacks

   • Brute Force Attacks
   • Dictionary Attacks
   • Password cracking attempts

3. Signal-Based Vulnerabilities

   • Signal Jamming
   • Wireless Interference
   • Range exploitation
