Meet Christopher, an architect with a decade of Azure and cybersecurity experience, who translates complex topics into clear, real-world, hands-on cloud and AI architectures with practical insights.
Explore how growing complexity across people, cloud, endpoints, and OT/IoT intensifies cyber security challenges, including talent shortages and data overload. Learn why interfaces and synergies between disconnected products matter.
Explore how a security operations center uses threat intelligence, indicators of compromise collection, threat hunting, log management, and incident response to detect threats, analyze incidents, and reduce the attack surface.
Explore the three-tier SoC model, where automation handles commodity malware and alerts, tier one tackles easier tasks, tier two handles advanced threats, and tier three conducts threat hunting and forensics.
Outline the NIST-based cyber security incident response process, from preparation and detection to containment, eradication, and recovery, including triage, post-incident lessons learned, and iterative analysis.
Demystify EDR, XDR, SIEM, and SOAR concepts using Defender for Endpoint, Defender for Cloud, Sentinel, and Logic Apps.
Explore blue teams' security monitoring, incident response, forensics, and threat hunting. See red teams perform vulnerability assessments and penetration testing, while purple teaming unites blue and red to boost security.
