Gain Privileges or Assume Identity

Etkilenen güvenlik alanları: Access Control

A user can assume the identity of another user with separate privileges in another context. This will give the user unauthorized access that may allow them to acquire the access information of other users.

Detay
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Architecture and Design · Operation

Environment Hardening

Detay
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.

Architecture and Design

Separation of Privilege

Detay
Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
