Transcript

In this section of the course, you'll learn why Linux is considered to be a relatively secure operating system. We'll talk about a special account on Linux systems called the superuser and how it differs from other accounts on a Linux system. You'll learn why Linux systems are often avoided by attackers and why this is both a good and bad thing. Next, we'll look at the security implications of using open source software such as Linux. From there, you'll learn how Linux systems manage software and security benefits that result from that design. We'll also look at the roles users and system administrators play in security. Next, we'll look at several security principles that you can use to guide you in making security-conscious decisions going forward. You'll also learn how to look at software and network services through the lens of security. We'll also touch on encryption, how to handle accounts and multi-factor authentication. Finally, we'll wrap up things with a discussion on the principle of least privilege, what that means and how you can apply it to your Linux systems.
