Recon Troubleshooting
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 diagnostic course focuses on identifying, analyzing, and resolving common failures, misconfigurations, and operational issues. At an expert level, RCCE students will learn systematic troubleshooting methodologies that accelerate root-cause analysis and minimize downtime. Students work through realistic break-fix scenarios that build the diagnostic confidence needed for high-pressure production environments.
