Mitigation MIT-1
Architecture and Design Operation

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

Mitigation MIT-48
Architecture and Design

Strategy: Separation of Privilege

Follow the principle of least privilege when assigning access rights to entities in a software system.

Mitigation MIT-49
Architecture and Design

Strategy: Separation of Privilege

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

CAPEC-122: Privilege Abuse

An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.

CAPEC-233: Privilege Escalation

An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

CAPEC-58: Restful Privilege Elevation

An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
