HTTPS

HTTPStart here

HTTP is the protocol browsers and applications use to request and transfer web content.

DNS over HTTPS (DoH)

A protocol that sends DNS queries encrypted inside HTTPS, hiding them from network observers. It improves user privacy but complicates defensive monitoring, since DNS lookups no longer appear in plain network traffic.

HSTS

HTTP Strict Transport Security: a web security header that tells browsers to only connect to a site over HTTPS, preventing downgrade to insecure HTTP and protecting against certain interception and stripping attacks.

TLS

TLS is a protocol that encrypts network communication and helps verify the identity of the service being contacted.
