HTTP/S Troubleshooting
RCCE students will learn HTTP and HTTPS protocol security including request/response analysis, header security (HSTS, CSP, X-Frame-Options), TLS/SSL configuration, certificate management, and common HTTP-based attacks. RCCE students will learn to analyze HTTP traffic for security issues, configure security headers to protect web applications, implement proper TLS configurations, manage digital certificates, detect and investigate HTTP-based attacks including request smuggling, host header injection, and cookie manipulation, troubleshoot HTTPS connectivity issues, and audit web server configurations for security weaknesses. This diagnostic course focuses on identifying, analyzing, and resolving common failures, misconfigurations, and operational issues. Starting from foundational concepts, 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.
