This CompTIA Linux+ security course focuses on securing Linux environments by implementing authentication, access controls, firewall configurations, and system hardening techniques.
In today's digital landscape, securing Linux systems is more important than ever. This course, Security for CompTIA Linux+ (XK0-006), equips IT professionals, system administrators, and security practitioners with the practical skills and knowledge required to harden Linux environments, protect critical data, and mitigate cyber threats. This course blends theoretical concepts with hands-on exercises, ensuring learners develop the expertise needed to safeguard Linux systems in enterprise environments. First, you will begin with an introduction to Linux security principles, covering authorization, authentication, and accounting methods. You will explore pluggable authentication modules (PAM), system security services daemon (SSSD), Kerberos, and lightweight directory access protocol (LDAP) to strengthen access control. Next, you will focus on firewall configuration and network security, where you will learn to implement firewalld, uncomplicated firewall (UFW), nftables, and iptables to secure network traffic. Finally, you will explore operating system (OS) hardening techniques, including privilege escalation control (sudo, su -), file permissions (ACLs, SELinux), secure remote access, and cryptographic best practices. Topics such as data encryption, certificate management, and secure boot configurations will provide a comprehensive approach to Linux security. By the end of this course, you will be able to implement robust authentication and authorization mechanisms to protect Linux systems, configure and manage firewalls to secure network communication, and apply OS hardening and cryptographic techniques to mitigate security vulnerabilities.
