Consul relies on both a lightweight gossip mechanism and an RPC system to
|
|
|
|
|
provide various features. Both of the systems have different security
|
|
|
|
|
mechanisms that stem from their designs. However, the security mechanisms of
|
|
|
|
|
Consul have a common goal: to provide confidentiality, integrity, and
|
|
|
|
|
authentication.

Requirements and recommendations for operating a secure Consul deployment may vary drastically depending on your
|
|
|
|
|
intended workloads, operating system, and environment. You can find detailed information about the various personas,

recommendations, requirements, and threats [here](/docs/security/security-models).

Consul provides an optional [Access Control List (ACL) system](/docs/security/acl) which can be used to control access
|
|
|
|
|
to data and APIs.

The Consul agent supports encrypting all of its network traffic. The exact method of encryption is described on the
|
|
|
|
|
[encryption security page](/docs/security/encryption). There are two separate encryption systems, one for gossip
|
|
|
|
|
traffic and one for HTTP + RPC.
