R264. Request authentication

Requirement

The system must require authentication for all resources, except for the consultation or visualization of those specifically classified as public.

Description

Sometimes systems have information and other resources that are not considered public. These resources should be protected by a secure authentication mechanism that prevents unauthorized actors from accessing them.

  1. CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs. In the case that the administrator failed to specify an Access Control List (ACL) for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application.

  2. CAPEC-36: Using Unpublished Interfaces. An adversary searches for and invokes interfaces that the target system designers did not intend to be publicly available. If these interfaces fail to authenticate requests the attacker may be able to invoke functionality they are not authorized for.

  3. CAPEC-115: Authentication Bypass. An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.

  4. CWE-287: Improper Authentication. When an actor claims to have a given identity, the software does not prove or insufficiently proves that the claim is correct.

  5. CWE-306: Missing Authentication for Critical Function. The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

  10. OWASP Top 10 A2:2017-Broken Authentication. Application functions related to authentication and session management are often implemented incorrectly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit other implementation flaws to assume other users' identities temporarily or permanently.

  11. OWASP Top 10 A3:2017-Sensitive Data Exposure. Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data may be compromised without extra protection, such as encryption at rest or in transit, and requires special precautions when exchanged with the browser.
