Why It Matters
Domain Name System Security Extensions – or DNSSEC – allows users to have more confidence in the online activities that are increasingly becoming a part of our lives at work, home, and school. DNSSEC acts like tamper-proof packaging for domain name data, helping to ensure that you are communicating with the correct website or service.
Before you connect to a website, your browser will use the DNS to retrieve an IP address. However, it is possible for an attacker to intercept your DNS query and provide false information. DNSSEC provides a level of additional security so that your browser can check to make sure the DNS information has not been modified.
