Security Features and Setup

Required Configurable Security Features. You must set up the following required security features:

  • Whitelist
    Atlas only allows client connections to the cluster from entries in the group’s whitelist. To connect, you must add an entry to the whitelist. To set up the whitelist for the group, see Add Entries to the Whitelist.
  • User Authentication/Authorization
    Atlas requires clients to authenticate to access the clusters, i.e. the MongoDB databases. You must create MongoDB users to access the database. To set up MongoDB users to your clusters, see Add MongoDB Users.

Optional Security Feature. Atlas provides the following optional security feature that you can set up:

Non-configurable Security Features. The following non-configurable security features are inherent to Atlas:

  • TLS/SSL
    Atlas uses TLS/SSL to encrypt the connections to your databases.
  • Virtual private cloud (VPC)
    A unique AWS Virtual Private Cloud is created for each Atlas group. All clusters for the group are deployed inside this VPC. This region-specific VPC is created for the Atlas group during the deployment of the group’s first cluster.
