Email Troubleshooting: In Practice
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 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.
