How does IAM play a crucial role in the CMMC Framework?


One of the most basic but crucial security measures accessible is user access. With the numerous ways we blend on-site and cloud services for customers, it’s easy to see how identification and Authentication Management (IAM) may go from a straightforward concept to a complex procedure that leaves you exposed or out of compliance.

Access Control and CMMC

The Cybersecurity Maturity Model Certification (CMMC solution) framework includes a wide range of topics related to cybercrime, risk assessment, and data stewardship. This architecture is made up of multiple parts that make up the various security requirements that an enterprise must achieve in order to manage increasingly sensitive data.

Domains highlight multiple, broad areas of security and functionality that a corporation might be required to adhere to, given their level in the CMMC classification system. Areas encompass security considerations such as Identification and Authentication (IA), Access Control (AC), and Incident Response (IR).

The first two capabilities listed here (Access Control and Identification and Authentication) cover related but distinct domains related to system access control. The IA domain involves the creation and upkeep of digital records and the devices used for authentication and authorization against those identities. This domain includes general authentication infrastructure, biometric logins, and Multi-Factor Authentication (MFA) capabilities.

The Access Control domain goes a step further by stressing physical and technical restrictions to guarantee that users who aren’t allowed to access resources don’t have access. The following are some of the more technical criteria frequently mentioned under Access Control:

The practice of controlling resource access depending on organization-wide roles as permission designations is known as role-based access control.

  • Identity and Access Management (IAM) refers to the process of managing digital identities and characteristics in relation to various degrees of access restrictions, such as roles, biometrics, and other solutions.
  • Zero-Trust Security Principles, or the requirement of authentication and identity from every new customer, Internet address, or gadget that links to the system, with no exceptions.
  • Privileged Access Management Systems, or the command of privileged identities in your system to reduce attack surfaces via elevated user accounts, are becoming increasingly popular.

IN BOTH CIRCUMSTANCES, the IA and AC domains act as a barrier among users and application assets. They give the tools you need to define roles for data access settings, implement system-wide identification and permission policies, secure physical places like desktops and server rooms, and protect your IT system as a whole. They also help a business complete CMMC compliance requirements

What are the capabilities of the Access Control Domain?

Every domain includes a set of “capabilities” that address various domain features. There are four features under Access Control:

C001: Set System Access Requirements. All measures and methods used to help establish who has rights to systems, what rules or regulations define that access, and how they can acquire access are included in this competency. This might encompass both technological and physical means.

C002: Control Internal System Access. PAM and the idea of least privilege are included. Guarantees that all institutional user access is regulated by correct policy and confined to the least amount of authority required for that user’s task.

C003: Control Remote System Access applies to remote work access control, which is extremely important in a post-pandemic society. Other access controls that help in safeguarding remote work might also be included.

C004: Only allow legitimate access and programs access to data. One example is safeguarding data against disclosure, primarily due to unintentional exposure from exchanging data through internal procedures or systems.
