Linux Systems Administration: Fundamentals of Linux Security
In this course, you will learn the basics of Linux system security. These are some of the tools and skills a system administrator needs to become a security engineer. This course focuses on network security issues and will help you improve the security of your systems by starting to think like an attacker.
Upon completion of this course, you will be able to:
- Verify password security.
- Enforce password strength via system policies.
- Assess system service security both locally and remotely
- Identify unknown open ports.
- Disable unwanted, insecure services.
- Analyze network packet captures for unencrypted data.
- Implement local system firewall controls using IPTables.
From beginning to end, you will learn by doing Linux-based projects and submitting them for instructor feedback. These projects, as well as the final project, will add to your portfolio. Besides a browser and Internet connection, all software is provided by The O’Reilly School of Technology.
Prerequisites: Linux Systems Administration: The Command Line, Linux Systems Administration: Networking and Package Management, or equivalent skills. This course is meant for the intermediate or advanced system administrator.
