|
|
|
Requirements and recomendations for operating a secure Consul deployment may vary drastically depending on your
|
2020-11-04 22:05:44 +00:00
|
|
|
intended workloads, operating system, and environment. Consul is not secure by default, but can be configured to satisfy
|
|
|
|
|
the security requirements for a wide-range of use cases from local developer environments without any configuration to
|
|
|
|
|
container orchestrators in-production with ACL authorization, and mTLS authentication.

### NIA
|
|
|
|
|
|
|
|
|
|
[Network Infrastructure Automation](/docs/nia) (NIA) enables dynamic updates to network infrastructure devices triggered
|
|
|
|
|
by service changes. Both the core Consul product's configuration and the configuration for the `consul-terraform-sync`
|
|
|
|
|
daemon used by NIA can affect the security of your deploymnet. You can read more about the various personas,
