Elastic Search Security Measures

cluster.name:

  1. Time taken for elasticsearch to start will be more.
  2. Slower Indexing and Results (since data is distributed).
  3. If one of the endpoints with which we formed cluster unknowingly is missing that means you have incomplete data.

node.name:

path.data:

network.host:

Others:

  1. When you’re exposing it on Public network, make sure you have some authentication and authorization plugin like shield is used, or your data is at RISK.
  2. when forming a cluster if you don’t set proper number of master nodes then chances of the cluster entering split brain issue is high and you cluster might lose data.
  3. if you’re planning for a cluster then keeping data nodes separate and having at least 1 replica will keep your cluster in high availability state and also serves as Disaster Management technique.
