I recently wrapped up a truly impactful series of four courses on LinkedIn Learning that have fundamentally shifted my perspective on modern cybersecurity. This wasn’t just about collecting certificates; it was a deliberate journey to connect the dots between strategic business governance (GRC), technical risk management, and proactive security operations (Threat Hunting).
Here’s a breakdown of the four courses and the key takeaways that are already shaping my approach to security.
1. Cybersecurity Foundations: Governance, Risk, and Compliance (GRC)
(By AJ Yawn)
Every effective cybersecurity program must start with a solid foundation, and this course provided the essential blueprint. AJ Yawn clearly lays out why GRC is not just an administrative burden, but the mechanism for aligning security with core business goals.
Key Takeaways:
- GRC as a Product: The powerful concept of viewing and scaling a GRC program as a product—constantly iterating and improving to meet organizational needs.
- Framework Fluency: A practical overview of critical compliance and security frameworks, including NIST CSF, ISO 27001, SOC 2, and HIPAA. Understanding these is essential for communicating risk across different business units.
- The Future of GRC: Insights into emerging areas like AI governance and how GRC professionals must adapt to manage risks associated with new technologies.
2. Managing Risk: A Solution Engineer’s Guide
(By Alan Berrey)
Moving from foundational GRC theory to practical application, this course offered a unique, customer-centric view of risk management. Alan Berrey focused on how technical professionals, particularly Solution Engineers, can turn the conversation about risk into a strategic advantage.
Key Takeaways:
- Risk as an Opponent: Understanding that risk is the number one challenge for customers, and a Solution Engineer’s role is to identify, mitigate, and overcome it.
- Expert Risk Modeling: Learning to differentiate between technical risk, sales risk, and business risk, and applying structured risk modeling techniques to provide reliable, data-backed solutions.
- Strategic Planning: Integrating risk management directly into the strategic planning process, ensuring that security decisions are proactive and support long-term business objectives.
3. Vulnerability Management: Assessing the Risks with CVSS, CISA KEV, EPSS, and SSVC
(By Lora Vaughn)
This course was a deep dive into the technical heart of risk prioritization. The sheer volume of vulnerabilities means security teams can no longer afford to treat all “High” scores equally. Lora Vaughn provided the necessary toolkit for data-driven prioritization.
Key Takeaways:
- Beyond Severity: The crucial distinction between vulnerability severity (raw CVSS score) and actual risk (CVSS adjusted with Temporal and Environmental metrics).
- Next-Gen Scoring: Mastering advanced prioritization systems:
- CISA KEV (Known Exploited Vulnerabilities): Prioritizing vulnerabilities actively exploited in the wild.
- EPSS (Exploit Prediction Scoring System): Using predictive modeling to focus on vulnerabilities likely to be exploited soon.
- SSVC (Stakeholder-Specific Vulnerability Categorization): Tailoring response based on organizational context and tolerance.
4. Threat Hunting Deep Dive: Intelligence-Based Detection and Response Strategies
(By Tino Sokic)
The final course shifted the focus from reactive vulnerability remediation to proactive, offensive-minded security. Tino Sokic walks through how to use threat intelligence to stop waiting for an alert and start actively searching for hidden malicious activity.
Key Takeaways:
- Intelligence-Driven Defense: How to operationalize threat intelligence (TI) and use frameworks like MITRE ATT&CK to build sophisticated hunting hypotheses.
- Proactive Detection: Moving beyond signature-based detection to behavioral analysis and anomaly hunting, allowing for the discovery of stealthy threats already within the network.
- Response Strategies: Integrating threat hunting results directly into the incident response pipeline to shorten detection and containment times dramatically.
The Integrated Security Mindset
Completing these four courses provided a holistic view of the security landscape—from the boardroom (GRC) to the hands-on technical work (Vulnerability Management and Threat Hunting).
The biggest lesson is integration: GRC defines the guardrails, Solution Engineering applies the strategy to business challenges, Vulnerability Management ensures our basic defenses are prioritized, and Threat Hunting makes sure nothing slips past our defenses unnoticed.
I’m energized by this knowledge and excited to apply these integrated concepts to build more robust, business-aligned, and proactive security programs. On to the next challenge!
