Write 4 pages explaining how access control lists play a role in a layered network security strategy, and the benefits available through domain separation, process isolation, resource encapsulation, and least privilege.

Write 4 pages explaining how access control lists play a role in a layered network security strategy, and the benefits available through domain separation, process isolation, resource encapsulation, and least privilege.

Explore the basics of operating systems and operating system security, including privileged and non-privileged states, threads and processes, and memory management. Focus on authentication and access controls including file systems, isolation, separation, and encapsulation.
Access controls and authentication systems are some of the most ubiquitous of all information security controls. Too often these controls still hinge on poorly implemented and managed password strategies. However, a wide array of technologies and tools is available to organizations seeking to secure their information assets. As governments create more regulations and organizations experience larger and more widely publicized breaches of personal data, these organizations may more frequently turn to additional layers of controls to supplement traditional access and authentication strategies.

Analyze the security characteristics of commonly used file systems.
Explain how access control lists play a role in a layered network security strategy.
Explain the security benefits available through domain separation, process isolation, resource encapsulation, and least privilege.
