What does DNS Poisoning primarily involve?

• A. Increasing network speed by optimizing routes
• B. Corrupting DNS data to redirect traffic
• C. Securing DNS servers against attacks
• D. Updating DNS records for new domains

Answer: (B)

DNS Poisoning primarily involves corrupting the DNS (Domain Name System) data to redirect traffic. This malicious technique exploits vulnerabilities in the DNS protocol, allowing an attacker to insert fake DNS responses into the cache of a DNS resolver or server. As a result, users attempting to access a legitimate website may instead be rerouted to a fraudulent one that the attacker controls. This can lead to various security threats, including phishing attempts, data theft, and the distribution of malware. By understanding DNS Poisoning, security analysts can better recognize the signs of an attack, implement monitoring strategies, and establish defenses against unauthorized access to DNS data. This area of knowledge is critical, as DNS is a foundational service on the internet, and its compromise can have wide-reaching consequences for both individuals and organizations.
