Attacks on data and data structures, including attempts to manipulate buffers, pointers, input data, or shared data.
Attacks on cryptography usage, including attempts to exploit weak, insecure, or inappropriate cryptographic implementations, algorithms, cipher suites, or modes of operation.
Attacks on business logic, including attempts to abuse or bypass application features and functionalities through the manipulation of APIs, communication protocols and channels, client-side functionality, or other system/application functions and resources. This includes cross-site scripting (XSS) and cross-site request forgery (CSRF).
Attacks on access control mechanisms, including attempts to bypass or abuse identification, authentication, or authorization mechanisms, or attempts to exploit weaknesses in the implementation of such mechanisms.
Attacks via any “high-risk” vulnerabilities identified in the vulnerability identification process, as defined in Requirement 6.3.1.		 Not applicable to Microsoft Entra ID.

6.3 Security vulnerabilities are identified and addressed.

PCI-DSS Defined approach requirements Microsoft Entra guidance and recommendations
6.3.1 Security vulnerabilities are identified and managed as follows:
New security vulnerabilities are identified using industry-recognized sources for security vulnerability information, including alerts from international and national/regional computer emergency response teams (CERTs).
Vulnerabilities are assigned a risk ranking based on industry best practices and consideration of potential impact.
Risk rankings identify, at a minimum, all vulnerabilities considered to be a high-risk or critical to the environment.
Vulnerabilities for bespoke and custom, and third-party software (for example operating systems and databases) are covered.		 Learn about vulnerabilities. MSRC | Security Updates, Security Update Guide
6.3.2 An inventory of bespoke and custom software, and third-party software components incorporated into bespoke and custom software is maintained to facilitate vulnerability and patch management.
