The access control mechanism on the Unix operating system is the main subject and emphasis of this research article. The risk analysis is a continual process that evaluates how successfully an operating system controls access to users, files, and applications. This is why, in order to accomplish our goal, we must constantly monitor, identify, and correct our operations, resources, and technology. As a result, the suggested ACM technique will be extremely helpful in preventing access from illegal outside sources. Through access control methods that demand Read, Write, and Execute across a UFS on a real-time operating system, this accountability is deployable. With pervasive, ubiquitous, and self-autonomous system resources for accountability and actionability to prevent our system, this algebraic relational mechanism would remove the disorder and uncertainty. The Algebraic Relational Logic (RFOS) suggested here has significant control over business, technology, and resources to address uncertainty in an organised manner at the appropriate moment. The objects, subjects, input, output, domain, and range would be systematically mapped to resource integration, communication, and synchronisation. Through the use of this algebraic ACM, which would benefit BCP and DRP, we must safeguard our secure business.
