How deeply does MongoDB 8.0 in Action, Third Edition cover SCRAM?

Explains challenge exchange, salting, repeated hashing, security benefits, and method-selection trade-offs without implementation commands.

SCRAM

As explained in MongoDB 8.0 in Action, Third Edition

SCRAM is a challenge-response authentication mechanism that derives authentication proofs from a username and password without transmitting the password directly.

SCRAM (Salted Challenge Response Authentication Mechanism) authenticates MongoDB users with passwords without transmitting those passwords in plain text. The client and server exchange cryptographic challenges while hashing the password with a unique salt and repeated iterations. section 20.2.1

SCRAM combines practical deployment with several security protections:

Keeps passwords off the network in plain-text form. section 20.2.1
Uses a unique random salt and repeated hashing to strengthen stored credential processing. section 20.2.1
Helps mitigate brute-force, interception, and replay attacks through cryptographic challenge exchange. section 20.2.1
Works broadly across MongoDB drivers and frameworks. section 20.2.1

General-purpose Atlas application

Choose SCRAM when an application needs straightforward, password-based authentication for MongoDB Atlas. Consider X.509 for strict-trust environments, OIDC or OAuth 2.0 when centralized identity and SSO matter, and AWS IAM for AWS-hosted services that should avoid traditional credentials. section 20.2.3
