DNS (Domain Name System) is the phonebook of the internet, translating domain names into IP addresses that computers can understand. Invented in the 1980s and maintained by InterNIC, it allows seamless internet communication by assigning domain names to devices connected to the internet. DNS is essential for smooth browsing and user-friendly navigation of the web.

Key Points:

  • How DNS Works: DNS uses a client-server approach to translate domain names into IP addresses, enabling internet devices to communicate.

  • Importance of DNS:

    • DNS makes internet navigation user-friendly by translating complex IP addresses into easily remembered domain names.

    • It allows organizations to make changes to their IP addresses without disrupting user access.

    • DNS helps mitigate security complexity, making it crucial for organizations sharing confidential data.

DNS Vulnerabilities:

  • Man In The Middle (MITM) Attacks: Attackers can intercept DNS requests and manipulate responses.

  • DNS Flood Attacks: Overwhelming DNS servers to disrupt their functionality.

  • Cache Poisoning: Attackers insert false data into DNS caches, misleading users to incorrect destinations.

  • DNS Spoofing: Redirecting users to deceptive websites to steal sensitive information.

Preventing DNS Vulnerabilities:

  • Keeping DNS resolvers private.

  • Regularly auditing applications and APIs for potential threats.

  • Implementing two-factor authentication for third-party DNS services.
