Email Deep Dive
RCCE students will learn email security architecture including SMTP protocol security, email authentication mechanisms (SPF, DKIM, DMARC), email gateway configuration, anti-phishing controls, attachment sandboxing, URL rewriting, and email encryption. RCCE students will learn to analyze email headers for spoofing indicators, configure email security controls to prevent business email compromise, investigate email-based attacks, implement data loss prevention for outbound email, deploy email encryption for sensitive communications, and tune email security rules to balance protection with business communication needs. This deep-dive course provides comprehensive technical coverage that goes beyond surface-level understanding. At an expert level, RCCE students will learn to master the nuances, edge cases, and advanced configurations that separate competent practitioners from true experts. Students will engage with complex real-world scenarios and gain the depth of knowledge required to troubleshoot difficult situations, mentor junior team members, and make architectural decisions with confidence.
