Why do we need DNSSEC and what does it actually do?

The article 'Why Do We Need DNSSEC?' explains the importance of DNSSEC, an extension of the DNS protocol that enhances security on the Internet. DNSSEC protects the integrity and authenticity of DNS data by cryptographically signing it. Without this protection, users are vulnerable to attacks such as DNS spoofing, where hackers can inject false IP addresses into the DNS system, leading to fraudulent websites. The article emphasizes that even small organizations can be targets of such attacks, making DNSSEC essential for anyone using the web. It also mentions that implementing DNSSEC is a crucial step towards ensuring greater security for synchronized databases used to identify server locations on the global network.
