Implementing Secure Access Controls in Computer Security Frameworks

Abstract

The concept of secure access controls is an essential element of contemporary computer security systems, as it provides the ability to grant access to sensitive information and system resources to authorized persons only. This paper discusses principles, models, and implementation strategies of effective access control such as discretionary, mandatory, role-based, and attribute-based approach. They include major elements like authentication, authorization, and auditing controls as well as integration with well-known security systems like NIST and ISO/IEC 27001. Other typical challenges brought forward by the study, like insider threats, cloud and remote access management, and scalability issues only indicate the presence of best practices, including the enforcement of least privileges, continuous monitoring, and policy automation. A formal way of using access control can help organizations to greatly improve their security stance and counter the emerging cyber threats.
