-Secure Sockets Layer (SSL) and Transport Layer Security (TLS) provide encryption for data-in-transit. While these terms are often used
-interchangeably, {kib} supports only TLS, which supersedes the old SSL protocols.
-
-TLS requires X.509 certificates to authenticate the communicating parties and perform encryption of data-in-transit. Each certificate
-contains a public key and has and an associated -- but separate -- private key; these keys are used for cryptographic operations. {kib}
-supports certificates and private keys in PEM or PKCS#12 format.
-
-In a standard TLS configuration, the server presents a signed certificate to authenticate itself to the client. In a mutual TLS
-configuration, the client also presents a signed certificate to authenticate itself to the server.
-
-When {es} {security-features} is enabled on your cluster, each request that {kib} (the client) makes to {es} (the server) must be
-authenticated. Most requests made by end users through {kib} to {es} are authenticated by using the credentials of the logged-in user. There
-are, however, a few internal requests that {kib} needs to make to {es}. For this reason, you must configure credentials for {kib} to use for
-those requests.
-
-If {kib} has `elasticsearch.username` and `elasticsearch.password` configured, it will attempt to use these to authenticate to {es} via the
-{ref}/native-realm.html[native realm]. However, {kib} also supports mutual TLS authentication with {es} via a {ref}/pki-realm.html[Public
-Key Infrastructure (PKI) realm]. To do so, {es} needs to verify the signature on the {kib} client certificate, and it also needs to map the
-client certificate's distinguished name (DN) to the appropriate `kibana_system` role.
