Wi-Fi Güvenliğinin Gelişimi: WEP, WPA, WPA2 ve WPA3

In the ever-evolving landscape of Wi-Fi technology, security protocols play a crucial role in protecting wireless networks from unauthorized access and cyber threats. From the early days of WEP to the latest advancements with WPA3, understanding the differences and enhancements in these protocols is vital for ensuring network security. This article delves into the details of WEP, WPA, WPA2, and WPA3, highlighting their key features, differences, and the evolution of Wi-Fi security standards.

Wi-Fi Güvenliğinin Gelişimi: WEP, WPA, WPA2 ve WPA3

WEP: The Pioneer with Flaws


  • Introduced: 1997
  • Standard: Part of the original IEEE 802.11 standard

Technical Aspects

  • Encryption: Utilizes RC4 stream cipher
  • Security Flaws: Vulnerable to multiple attack vectors, including IV (Initialization Vector) attacks and brute force
  • Current Status: Considered obsolete due to its weak security

WPA: A Temporary Security Enhancement


  • Launched: 2003
  • Purpose: Developed to address WEP’s vulnerabilities

Ana Özellikler

  • Encryption Method: Employs Temporal Key Integrity Protocol (TKIP) and RC4
  • Security Level: More secure than WEP, but TKIP vulnerabilities were later identified
  • Kullanımı: Served as an interim solution before the advent of WPA2

WPA2: Establishing a New Standard

Wi-Fi Güvenliğinin Gelişimi: WEP, WPA, WPA2 ve WPA3

Genel Bakış

  • Release Date: 2004
  • Significance: Became the most widely used Wi-Fi security protocol

Güvenlik ve Şifreleme

  • Core Encryption: Advanced Encryption Standard (AES) with Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP)
  • Security Improvements: Significantly more secure than its predecessors, addressing many of their vulnerabilities

Adoption and Usage

  • Uyumluluk: Supported by most modern Wi-Fi devices
  • Legacy Support: Backward compatibility with WPA

WPA3: Advancing Wi-Fi Security


  • Announcement: 2018
  • Goal: To further enhance Wi-Fi security and address modern threats
