Episode 63 — Perform Root Cause and Recovery Analysis: Metadata, Volatile Data, Host, and Network
This episode teaches how to perform root cause and recovery analysis after an incident so you can eliminate the true failure mode and restore services safely, which SecurityX often tests through…
Episode 62 — Analyze Incident Artifacts: Sandboxing, IoC Extraction, Stylometry, Reverse Engineering
This episode focuses on incident artifact analysis as a disciplined process for understanding what happened and what to do next, which SecurityX tests because successful response depends on…
Episode 61 — Turn Intelligence Into Action: TIPs, IoC Sharing, STIX/TAXII, Sigma, YARA, Snort
This episode teaches how to turn threat intelligence into operational security improvements, because SecurityX expects you to treat intelligence as a decision input that drives detections,…
Episode 60 — Apply Threat Hunting and Intelligence: Internal Sources, OSINT, Dark Web, ISACs
This episode explains how to apply threat hunting and intelligence as complementary practices, which SecurityX tests because strong programs do not wait passively for alerts when adversaries adapt…
Episode 59 — Recommend Attack Surface Reductions: Validation, Patching, Encryption, Defense-in-Depth
This episode teaches how to recommend attack surface reductions that measurably reduce risk, which SecurityX tests by presenting environments where many fixes are possible but only a few will reduce…
Episode 58 — Analyze Vulnerabilities and Attacks: Injection, XSS, SSRF, Misconfigurations, Secrets
This episode builds practical vulnerability analysis skills for attack types SecurityX expects you to recognize quickly, including injection, XSS, SSRF, misconfigurations, and secret exposure, with…
Episode 57 — Incorporate Diverse Data Sources: Threat Feeds, Scans, Bounties, CSPM, Logs, DLP
This episode teaches how to incorporate diverse security data sources into a coherent detection and risk picture, which SecurityX tests because mature programs fuse signals rather than treating each…
Episode 56 — Make Alerts Actionable: Prioritization Factors, Failures, and False Positive Control
This episode focuses on making alerts actionable, a frequent SecurityX scenario theme because an alert that cannot drive a clear decision is operationally equivalent to no alert at all. You’ll learn…
Episode 55 — Analyze Monitoring Data Like a Defender: SIEM Parsing, Retention, Baselines, Correlation
This episode teaches how to analyze monitoring data the way defenders do when they are trying to separate real threats from background noise, which SecurityX tests because detection success depends…
Episode 54 — Apply Cryptography Correctly: Use Cases, Key Management Models, and Practical Techniques
This episode focuses on applying cryptography correctly, because SecurityX regularly tests the difference between “we use encryption” and “we designed encryption with the right keys, boundaries, and…
Episode 53 — Explain Advanced Cryptography: PQC, Forward Secrecy, AEAD, Homomorphic Encryption
This episode breaks down advanced cryptography concepts that appear in SecurityX as decision-making topics, where you must recognize what a technique provides and when it is appropriate rather than…
Episode 52 — Use Automation to Secure the Enterprise: IaC, Triggers, Patching, SOAR, SCAP
This episode explains how to use automation to improve security outcomes at scale, a core SecurityX theme because consistent, repeatable controls usually beat heroic manual effort in large…
Episode 51 — Secure Specialized and Legacy Systems: Constraints, Obsolescence, Unsupported Reality
This episode teaches how to secure specialized and legacy systems when modern control assumptions do not apply, which SecurityX tests because real enterprises run critical workloads on platforms that…
Episode 50 — Secure OT and IoT Systems: SCADA, ICS, Embedded, RF, Segmentation, Monitoring
This episode focuses on securing OT and IoT systems with a practical understanding of constraints, because SecurityX often tests whether you can apply security principles in environments where…
Episode 49 — Defend Against Firmware and Physical TTPs: Shimming, USB Attacks, BIOS/UEFI, Memory
This episode teaches how to defend against firmware and physical tactics, techniques, and procedures that bypass many traditional controls, which SecurityX tests because real attackers use physical…
Episode 48 — Implement Hardware Security: TPM, HSM, vTPM, Secure Boot, Measured Boot, Enclaves
This episode explains how to implement hardware security in a way that strengthens trust and reduces key exposure, which SecurityX tests because hardware-backed controls are often the difference…
Episode 47 — Fix IPS/IDS and Observability Gaps: Rule Quality, Placement, False Positives, Coverage
This episode teaches how to fix IPS/IDS and observability gaps by focusing on the quality of detection logic and the reality of traffic visibility, because SecurityX scenarios often hinge on why a…
Episode 46 — Troubleshoot Network Infrastructure Issues: DNSSEC, DKIM/SPF/DMARC, TLS, Cipher Mismatch
This episode prepares you to troubleshoot network infrastructure issues that affect both security and availability, which SecurityX tests because misconfigurations in DNS and TLS can silently break…
Episode 45 — Reduce Endpoint Attack Surface: Application Control, Configuration Management, Isolation
This episode teaches endpoint attack surface reduction as a deliberate engineering effort, not a one-time checklist, because SecurityX scenarios often reward answers that remove whole classes of…
Episode 43 — Harden Secrets Management: Tokens, Certificates, Passwords, Keys, Rotation, Deletion
This episode teaches secrets management as an operational system that must be designed for lifecycle control, because SecurityX questions often focus on the real causes of compromise: leaked tokens,…
