MongoDB Documentation  Release 3.0.4 6.5.2 Configure Role-Based Access Control 6.5.3 Encrypt Communication 6.5.4 Limit Network Exposure 6.5.5 Audit System Activity 6.5.6 Encrypt and Protect Data 6.5.7 Run MongoDB with a Dedicated User Create roles that define the exact access a set of users needs. Follow a principle of least privilege. Then create users and assign them only the roles they need to perform their operations. A user can be a person or a client application. Create a user administrator first  then create additional users. Create a unique MongoDB user for each person and application that accesses the system. See Authorization (page 324)  Create a Role (page 388)  Create a User Administrator (page 384)  and Add a User to a Database (page 386). Configure MongoDB to use TLS/SSL for all incoming and outgoing connections. Use TLS/SSL to encrypt commu- nication between mongod and mongos components of a MongoDB client as well as between all applications and MongoDB. See Configure mongod and mongos for TLS/SSL (page 342). Ensure that MongoDB runs in a trusted network environment and limit the interfaces on which MongoDB instances listen for incoming connections. Allow only trusted clients to access the network interfaces and ports on which MongoDB instances are available. See the bindIp setting  and see Configure Linux iptables Firewall for MongoDB (page 335) and Configure Windows netsh Firewall for MongoDB (page 339). Track access and changes to database configurations and data. MongoDB Enterprise 88 includes a system auditing facility that can record system events (e.g. user operations  connection events) on a MongoDB instance. These audit records permit forensic analysis and allow administrators to verify proper controls. See Auditing (page 330) and Configure System Events Auditing (page 398). Encrypt MongoDB data on each host using file-system  device  or physical encryption. Protect MongoDB data using file-system permissions. MongoDB data includes data files  configuration files  auditing logs  and key files. Run MongoDB processes with a dedicated operating system user account. Ensure that the account has permissions to access data but no unnecessary permissions. See Install MongoDB (page 5) for more information on running MongoDB. $^{88}$http://www.mongodb.com/products/mongodb-enterprise?jmp=docs 432 Chapter 6. Security
