# Grafana technical terminology

<!-- Keep terms in alphabetical order: -->

This glossary defines technical terms used in Grafana.

## TLS/SSL

The acronyms [TLS](https://en.wikipedia.org/wiki/Transport_Layer_Security) (Transport Layer Security) and
[SSL](https://en.wikipedia.org/wiki/SSL) (Secure Socket Layer) are both used to describe the HTTPS security layer.
In practice, they are synonymous. However, TLS is considered the current name for the technology, and SSL is considered
[deprecated](https://tools.ietf.org/html/rfc7568).

As such, while we use both terms in our codebase and documentation, we generally prefer TLS.
However, we use both acronyms in combination when referring to this type of technology, that is, _TLS/SSL_. We do this because we don't want to confuse readers who may not be aware of them being synonymous, and SSL is still prevalent in common discourse.
