In this intermediate Linux skills training, Shawn Powers prepares learners to take the security portion of the CompTIA Linux+ certification.

No matter how many developers the big OS providers employ, the number of developers working on Linux is still bigger. That’s the power of open source – and what makes Linux an operating system inherently secure, but it’s not hard to shatter that security. This Linux training covers how to keep your Linux servers secure.

After completing this Linux training you’ll know how to secure your Linux system at boot by using the BIOS, UEFI, or boot loader, configure multi-factor authentication (MFA), manage users in order to prevent the sharing of IDs, disable hosts and unused or unsecured services, and how to enable SSL/TLS and auditd.

This CompTIA Linux+ training covers XK0-004 security exam objectives, including these topics:
Understanding how PAM configuration affects security
Using pam_faillock or pam_tally2 for managing account locking
Creating and using SSH keypairs
Understanding and assigning Linux file permissions
Managing security with multi-factor authentication and alternate authentication methods
Securing and separating OS data and application data
Understanding encryption options
Diagnosing and analyzing network data flow
Using stateful and stateless firewalls
Managing log rotation
