Secure Connections, Security, and Technology Standards

Secure Connections (HTTPS, HSTS)

Unencrypted HTTP connections create a privacy vulnerability and can expose potentially sensitive information that is susceptible to interception, manipulation, and impersonation. This data can include browser identity, website content, search terms, and other user-submitted information. The Department of Transportation (DOT) and Operating Administration (OA) websites use Secure Connections (HTTPS) and HTTP Strict Transport Security (HSTS).


DOT understands the threat against the nation’s cyber infrastructure and has made cybersecurity a top priority. You can learn about DOT’s  Cybersecurity, Privacy and Information Assurance Technology Operations and Infrastructure here.

Technology Standards

DOT uses the most recent and up-to-date technical standards for our digital services, and provides our service through a secure connection.
