How effective is DNSSEC in preventing spoofing or DNS attacks?

DNSSEC (Domain Name System Security Extensions) is highly effective in preventing DNS spoofing and cache poisoning attacks. It works by digitally signing DNS data to ensure its authenticity, making it difficult for attackers to forge or manipulate DNS responses. While DNSSEC doesn't encrypt the data itself, it ensures that users are directed to the correct websites and not malicious lookalikes. However, its effectiveness depends on proper implementation across the DNS infrastructure. For professionals looking to understand and deploy DNSSEC securely, enrolling in a Cyber security training program is recommended. It provides practical knowledge of DNS threats and modern mitigation strategies.
