Multilayer user access control is an essential framework in cybersecurity that provides a robust method for safeguarding sensitive information and systems. Implementing effective multilayer access control involves various methods, each offering unique benefits to ensure comprehensive security. This paper explores specific implementation methods suitable for multilayer access control, elucidates how each contributes to the overall security architecture, and discusses their individual and combined advantages in creating a resilient access environment.

One of the primary methods of implementing multilayer access control is through Role-Based Access Control (RBAC). RBAC assigns permissions to users based on their roles within an organization. This method simplifies management by grouping permissions into roles that correspond to job functions, such as administrator, manager, or employee. It benefits multilayered access control by providing clear, manageable access pathways that align with organizational hierarchies and responsibilities. Layers are naturally created by assigning different roles with varying levels of access, thus limiting users to only the data and systems necessary for their roles (Sandhu et al., 1996). RBAC is highly scalable, facilitates audit and compliance activities, and reduces the risk of privilege escalation or inappropriate access.

Another significant method is Attribute-Based Access Control (ABAC). ABAC uses attributes—characteristics of users, resources, or environment conditions—as a basis for governing access decisions. For example, user attributes like department, security clearance, or location, combined with resource attributes such as classification level, form the basis for access permissions. This method benefits multilayered access control by enabling fine-grained, context-aware access policies. For instance, an employee might access certain data only during work hours or from a specific location, adding dynamic programming layers that respond to varying conditions (Hu et al., 2015). ABAC provides flexibility for complex environments requiring tailored access control policies adaptable to evolving organizational needs.

Discretionary Access Control (DAC) is another traditional method that grants data owners the authority to decide who can access their resources. DAC enhances multilayered access control by allowing owners to implement specific rules for access, creating personalized layers of security dependent on the discretion of data custodians. While DAC can be more flexible and user-friendly, its potential downside is weaker enforcement compared to RBAC or ABAC, especially in large, complex organizations. However, when combined with other methods, DAC can contribute additional layers of personalized permission settings (Li et al., 2017).

Mandatory Access Control (MAC) complements the previous methods by enforcing system-wide policies derived from security labels assigned to objects and users. For example, classified data might be accessible only to users with a matching security clearance. MAC creates strict security layers by removing user discretion, which is particularly useful in highly sensitive environments such as military or government agencies. Its benefit lies in ensuring that security policies are uniformly enforced across all systems, preventing inadvertent or malicious breaches (Ferraiolo et al., 2007). When integrated with other access control models, MAC offers an additional security layer based on system-imposed restrictions.

Combining these methods often yields the most effective multilayer access control system. For instance, organizations might employ RBAC for structured role management, ABAC for context-aware flexibility, MAC for high-security environments, and DAC for user-specific needs. This layered approach ensures multiple points of control, addressing different threat vectors and organizational requirements. Implementing a hybrid model enhances security robustness, compliance, and operational efficiency, as each method compensates for the limitations of others (Chapman & Johnson, 2020).

In conclusion, implementing multilayer user access control relies on various methods, each offering distinctive benefits. RBAC simplifies management and clarifies role-based privileges; ABAC introduces fine-grained, context-sensitive policies; DAC provides flexibility and user discretion; and MAC ensures strict enforcing of policies in sensitive environments. Combining these strategies enables organizations to construct a comprehensive, adaptable, and secure access control system capable of defending against diverse threats and coping with complex operational demands.
