Data Security

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. Learners explore how SIEM and SOAR platforms collect, prioritize, and report alarms, while also examining Cisco SecureX and the Security Onion toolset for practical security operations workflows. The course also explains PCAP storage requirements, packet capture investigation with tcpdump, and the importance of correlating NSM data during incident response. Unique differentiators include real-world examples such as SHA-1, plus coverage of privacy and compliance constraints tied to HIPAA, FISMA, PCI DSS, and Sarbanes-Oxley. Ideal for SOC analysts seeking stronger skills in cryptography, packet analysis, and encrypted traffic investigation.
