Linux Security Techniques

Securing a Linux system requires a layered approach that addresses data protection, access control, network security, and compliance. This course introduces the key security features found in modern Linux distributions, giving IT professionals, system administrators, and security practitioners the tools they need to protect sensitive data and harden systems in enterprise and cloud environments. Explore how to monitor and audit security events using syslog, journald, and fail2ban; encrypt data with LUKS, GPG, and SSH; secure services with SELinux and chroot jails; configure and verify network security with iptables and firewalld; and apply basic penetration testing to confirm that each security technique is properly implemented.
