DNS Security Extensions (DNSSEC) adds a layer of security to the DNS lookup and response process which can prevent users from being redirected to fraudulent websites, a common goal of typosquatting. DNSSEC ensures that the DNS data has not been modified from its original state and is especially useful if the DNS system is returning proper results and there are no known Indicators of Compromise (IoCs). It uses digital signatures and public-key encryption to provide authentication for DNS data.
