Securing Cloud Infrastructure Using Policy-Based Access Control in Cybersecurity

This abstract explores the integration of PBAC in cloud environments as a cybersecurity frameworkthat ensures only authorized users and devices access critical resources. By using context-aware policies,PBAC enhances the granularity of access control, minimizes the risks associated with privilege escalation,and mitigates potential threats like unauthorized data access, insider attacks, and external breaches. Thepaper highlights how PBAC can complement traditional security mechanisms, such as identity and accessmanagement (IAM), to provide a more adaptive and scalable approach to cloud security, improvingcompliance with industry regulations while safeguarding against emerging cyber threats.
