Cracking of wireless networks is the defeating of security devices in Wireless local-area networks. Wireless local-area networks(WLANs) – also called Wi-Fi networks are inherently vulnerable to security lapses that wired networks Cracking is a kind of information network attack that is akin to a direct intrusion. There are two basic types of vulnerabilities associated with WLANs: those caused by poor configuration and those caused by weak encryption.

WPA3 provides several security improvements over WPA2: 1. It uses a more secure handshake called Simultaneous Authentication of Equals (SAE) that is resistant to offline dictionary attacks. 2. It enables encryption for open WiFi networks through Opportunistic Wireless Encryption (OWE) without requiring a pre-shared password. 3. It supports connecting devices without displays through the Device Provisioning Protocol (DPP) using QR codes and other contactless methods. 4. It enhances cryptographic strength with a 192-bit security suite aligned with government standards.

WPA-3 improves upon WPA-2 in several ways. It replaces the 4-way handshake of WPA-2 with Simultaneous Authentication of Equals (SAE) defined in IEEE 802.11s. For enterprise networks, it integrates backend authentication using Elliptic Curve Diffie-Hellman key exchange and Elliptic Curve Digital Signature Algorithm with a 384-bit elliptic curve. It also introduces the ability to share Wi-Fi credentials through QR codes. WPA-3 aims to address weaknesses in WPA-2 like offline dictionary attacks of captured handshakes by moving to zero-knowledge authentication methods.

The document provides an overview of ethical hacking, including definitions, goals, and the typical 5 phases of hacking: reconnaissance, scanning, gaining access, maintaining access, and covering tracks. It describes the importance of reconnaissance in gathering target information through passive and active means. Scanning involves using tools to discover technical details about a network like open ports and services. Gaining access focuses on exploiting vulnerabilities to infiltrate systems, while maintaining access ensures continued infiltration even after reboots. Covering tracks aims to remove evidence and logs of the intrusion. The document provides examples of techniques for each phase.
