About

The HTTP Strict Transport Security (HSTS) standard is a web security mechanism that ensures a user's browser always connects to a website using HTTPS, preventing insecure HTTP access.

It is enforced through the Strict-Transport-Security response header, which defines a policy duration, can apply to all subdomains, automatically upgrades HTTP requests to HTTPS, and protects against protocol downgrade attacks and cookie hijacking.

Transport Layer Security (TLS) is a cryptographic protocol that provides end-to-end encryption of data transmitted over the Internet, ensuring confidentiality, integrity, and authentication between communicating systems.

It is used in HTTPS to secure communication between browsers and servers, combining asymmetric cryptography for key exchange, symmetric encryption for data transfer, and digital certificates to verify server identity.
