T1556.009: Conditional Access Policies

Conditional Access Policies (T1556.009) é uma técnica catalogada no MITRE ATT&CK Enterprise usada como referência para mapear comportamento adversário em auditorias de segurança.

Técnica T1556.009 Enterprise ATT&CK

Contexto para AppSec

Em uma auditoria de AppSec, Conditional Access Policies deve ser usada para revisar caminhos em que código, configuração, dependências ou infraestrutura podem viabilizar o comportamento descrito pela MITRE. No ATT&CK, ela aparece em Defense Impairment, Persistence e Credential Access. As plataformas mapeadas pela MITRE incluem IaaS e Identity Provider. No Vigly, esse contexto ajuda a conectar evidências do repositório com priorização e remediação.

Descrição oficial original do MITRE ATT&CK

Adversaries may disable or modify conditional access policies to enable persistent access to compromised accounts. Conditional access policies are additional verifications used by identity providers and identity and access management systems to determine whether a user should be granted access to a resource. For example, in Entra ID, Okta, and JumpCloud, users can be denied access to applications based on their IP address, device enrollment status, and use of multi-factor authentication. In some cases, identity providers may also support the use of risk-based metrics to deny sign-ins based on a variety of indicators. In AWS and GCP, IAM policies can contain condition attributes that verify arbitrary constraints such as the source IP, the date the request was made, and the nature of the resources or regions being requested. These measures help to prevent compromised credentials from resulting in unauthorized access to data or resources, as well as limit user permissions to only those required. By modifying conditional access policies, such as adding additional trusted IP ranges, removing Multi-Factor Authentication requirements, or allowing additional Unused/Unsupported Cloud Regions, adversaries may be able to ensure persistent access to accounts and circumvent defensive measures.
