Encrypted traffic now dominates modern networks, and with more than 50 percent of internet traffic protected by TLS/SSL, SOC analysts need the skills to detect threats hidden inside that blind spot. This cybersecurity course teaches associate-level analysts how cryptography, encrypted network communication, and network security monitoring (NSM) intersect in real-world security operations. Designed for learners with CCNA-level networking knowledge, it covers the data that powers network security analysis, including session data, full packet capture, transaction data, extracted content, alert data, statistical data, and metadata.
