The Domain Name System (DNS) provides a critical service for the Internet. The DNS acts as an online directory, translating easy-to-remember domain names (e.g., govtech.com) into an IP address (e.g., 220.127.116.11). Unfortunately, traditional DNS lookups are inherently insecure. While website owners can mitigate these security vulnerabilities, few state governments have taken the necessary steps to do so. In a column for Government Technology, Daniel Castro explains how states can improve the security of their government websites by implementing DNS security extensions, or DNSSEC, on all state government domains.
