Hardening for Beginners
RCCE students will learn endpoint hardening methodologies including operating system configuration lockdown, unnecessary service removal, registry hardening, group policy enforcement, application whitelisting, and CIS Benchmark implementation. RCCE students will learn to apply hardening baselines to Windows, Linux, and macOS systems, reduce the attack surface by disabling unused ports and protocols, configure host-based firewalls and intrusion prevention, implement secure boot and firmware protection, manage local administrator accounts, and validate hardening effectiveness through vulnerability scanning and compliance auditing. Designed for students with no prior experience in this area, this course builds knowledge from the ground up with clear explanations, guided demonstrations, and progressive skill-building. Starting from foundational concepts, RCCE students will learn core concepts through practical examples that connect theory to real-world security operations. By completion, students will have the foundational knowledge and hands-on confidence needed to contribute in professional cybersecurity roles.
