Step into the world of cybersecurity's defenders as we explore the tools, techniques, and strategies used to protect networks from attack. Following the NIST Cybersecurity Framework, each episode examines a different aspect of defensive security operations - from system hardening and vulnerability scanning to incident response and recovery. Through practical demonstrations and expert analysis, we'll show how blue teams use tools like Nmap, Nessus, and OpenVAS to identify threats, implement security controls, and respond to incidents across both Windows and Linux environments. Learn the command-line wizardry that powers effective system defense, discover how to audit logs for signs of compromise, and master the art of malware analysis. Whether you're a security professional, system administrator, or aspiring blue team member, join us as we reveal the techniques that keep our digital infrastructure secure.
