Reconnaissance Hardening Clinic: Primer
RCCE students will learn reconnaissance methodologies including passive and active reconnaissance, OSINT gathering, network scanning, service enumeration, and target profiling for security assessments. RCCE students will learn to conduct passive reconnaissance using public data sources, DNS records, certificate transparency logs, and social media, perform active reconnaissance including port scanning, service fingerprinting, and web application enumeration, use tools including Nmap, Shodan, Censys, and custom scripts, map organizational attack surfaces, identify potential entry points and high-value targets, maintain operational security during reconnaissance, and document reconnaissance findings for penetration test planning. This hands-on hardening course focuses on reducing attack surface through practical configuration changes and security guardrails. Starting from foundational concepts, RCCE students will learn to apply hardening baselines, validate configurations, and measure the security improvement achieved. Students walk away with actionable hardening checklists and the skills to maintain hardened configurations as environments evolve.
