Network Infrastructure Attacks

What is a Computer Network?

A computer network is a collection of interconnected computers and devices that can share resources and communicate with each other.

The Devices that make up the Network Infrastructure



   
  • Hubs: Connect multiple devices on a network, broadcasting data to all connected devices. While older technology, they're still used in some basic setups.
  • Switches: Intelligent devices that connect multiple devices, directing data only to the intended recipient, improving network efficiency.
  • Routers: Connect multiple networks and direct data packets between them based on their destination IP addresses.
  • Bridges: Connect two similar networks, filtering traffic to prevent unnecessary data transmission.
  • Modems: Modulate/demodulate data signals for transmission over analog lines, often used for internet connections.
  • Repeaters: Amplify and regenerate signals to extend network coverage.
  • Gateways: Connect networks with different protocols, translating data between them.
  • Access Points (APs): Create wireless networks, allowing devices to connect without cables.
  • Firewalls: Security devices that monitor and filter incoming and outgoing network traffic based on security rules.

Network Infrastructure Attacks



     

Network infrastructure is a prime target for cyberattacks due to its critical role in facilitating communication and data flow. Here's a list of common attacks targeting network infrastructure:

Network Level Attacks:

      
  • Denial of Service (DoS) and Distributed Denial of Service (DDoS): Overwhelming network resources to prevent legitimate users from accessing services.
  • Man-in-the-Middle (MitM) Attacks: Intercepting and altering communication between two parties.
    • ARP Poisoning Compromising Address Resolution Protocol (ARP) to redirect network traffic.
    • DHCP Spoofing Manipulating Dynamic Host Configuration Protocol (DHCP) to assign IP addresses maliciously.
    • DNS Poisoning: Corrupting Domain Name System (DNS) to redirect traffic to malicious websites.
    • Eavesdropping: Interception of network traffic to gather information.
Infrastructure Device-Specific Attacks

      
  • Router Attacks: Compromising routers to gain unauthorized access, redirect traffic, or launch further attacks.
  • Switch Attacks: Exploiting vulnerabilities in switches to intercept or modify network traffic.
  • Firewall Evasion: Bypassing firewall security measures through various techniques.
  • Wireless Network Attacks: Targeting vulnerabilities in wireless networks, such as Wi-Fi hacking, rogue access points, and deauthentication attacks.
