Weakness (CWE)

CWE-654: Reliance on a Single Factor in a Security Decision

Base Draft

A protection mechanism relies exclusively, or to a large extent, on the evaluation of a single condition or the integrity of a single object or entity in order to make a decision about granting access to restricted resources or functionality.

How to prevent it (2 mitigations)

  1. Architecture and Design

    Use multiple simultaneous checks before granting access to critical operations or granting critical privileges. A weaker but helpful mitigation is to use several successive checks (multiple layers of security).

  2. Architecture and Design

    Use redundant access rules on different choke points (e.g., firewalls).
