Security & Virtualization
Explain the role of a Firewall (host-based or network-based) in OS security. Describe the two fundamental actions it can take regarding network traffic.
Compare Capability-Based Lists and Access Control Lists (ACLs) as mechanisms for protection. Which mechanism is better suited for a decentralized system and why?
List 4 distinct benefits of using Virtual Machines (VMs) in a modern computing environment (e.g., security, development). Distinguish between Type 1 and Type 2 Hypervisors.
Define the security principles of Least Privilege and Separation of Privilege. Provide a clear OS component example (e.g., file permissions) that implements each principle.
Describe the conceptual structure of an Access Control Matrix. Use a simple 3-user, 3-file example to illustrate how it determines if User A can read File X.
Explain what a Buffer Overflow vulnerability is at a basic level. Describe two common techniques an OS or compiler uses to prevent or mitigate this type of attack.
Define the Trusted Computing Base (TCB). Explain why minimizing the size and complexity of the TCB is a fundamental principle of secure operating system design.
Explain the concept of a Sandbox environment in OS security. Describe its primary purpose and how it uses isolation to protect the host system.
Compare Password-Based Authentication and Multi-Factor Authentication (MFA). Explain why MFA significantly reduces the risk of unauthorized access even if a user's password is compromised.
Explain the concept of Role-Based Access Control (RBAC). Compare it to Discretionary Access Control (DAC) and state why RBAC is preferred in enterprise environments.
Describe a common Denial-of-Service (DoS) attack aimed at an operating system (e.g., SYN Flood). Explain the specific OS resource the attack attempts to exhaust.
List 4 distinct categories of Biometric Authentication used in OS security (e.g., physiological, behavioral). State one significant security advantage over password-based methods.
Explain the security and stability importance of timely OS Patch Management. Describe the risks associated with delayed application of security patches (e.g., zero-day).
