Operating Systems Hardening
The intent of the Operating Systems Hardening Knowledge Unit is to provide students with the ability to apply methods such as managing applications, services, and network ports to improve the robustness of operating systems.
Topics
- Removing unnecessary components
- User restrictions (access and authorizations)
- Describe, for a given OS, the steps necessary for hardening the OS with respect to various applications.
- Vulnerability Scanning
Outcomes
- Describe, for a given OS, the steps necessary for hardening the OS with respect to various applications.
- Securely install a given OS, remove or shut down unnecessary components and services, close unnecessary ports, and ensure that all patches and updates are applied.
- Vulnerability Scanning
