Summary of Ethical Hacking Full Course for Beginners to Pro in 3 Hours [Part-2] 🔥 - 2025 Edition

Key Concepts and Features:

• Network Topology
  • Definition: Network Topology refers to the arrangement of different elements (links, nodes) in a computer network.
  • Types:
    • Physical Topology: The physical layout of devices and cables.
    • Logical Topology: The way data flows within the network.
  • Specific Topologies:
    • Star Topology: All nodes are connected to a central hub, enhancing security.
    • Bus Topology: All devices share a single communication line; susceptible to failure if the bus is damaged.
    • Ring Topology: Each device is connected to two others, forming a ring; data travels in one direction.
    • Mesh Topology: Each node connects to multiple nodes, providing redundancy but at a higher cost.
    • Hybrid Topology: Combines multiple topologies to suit specific needs.
• Hardware Components
  • NIC (Network Interface Card): Allows devices to connect to a network.
  • Hub: Connects multiple devices in a network segment.
  • Switch: Similar to a hub but more intelligent, directing data only to the intended recipient.
  • Router: Forwards data packets between networks.
  • Bridge: Connects two network segments.
  • Gateway: Serves as a "gate" between two networks, often using different protocols.
• OSI and TCP/IP Models
  • OSI Model: A conceptual framework used to understand network interactions in seven layers.
  • TCP/IP Model: A more practical model used in networking, consisting of four or five layers, depending on the version.
• IP Addressing
  • Types of IP Addresses: Public, private, static, dynamic.
  • DHCP (Dynamic Host Configuration Protocol): Automatically assigns IP addresses to devices on a network.
  • IPv6 Addressing: Discusses how to compress and generate unique IPv6 addresses.
• Computer Network Defense (CND)
  • Focuses on protecting networks through protection, detection, and response to unauthorized activities.
  • Key Principles:
    • Integrity: Ensuring information is not altered by unauthorized parties.
    • Confidentiality: Keeping sensitive information private.
    • Availability: Ensuring authorized users can access information when needed.
    • Authentication: Verifying the identity of users accessing the network.
• Firewall Configuration
  • Discusses the importance of configuring firewalls to block unauthorized access.
  • Types of Firewalls: Host-based, network-based, and virtual firewalls.
  • Rules and Policies: Setting rules for inbound and outbound traffic to enhance security.
• Troubleshooting Commands
  • Various Windows commands for network troubleshooting, including ipconfig, ping, and netstat, are introduced to help monitor and manage network traffic.
