CISSP Domain 1: Governance, Roles & Due Care (2026)

On the CISSP, senior management holds the ULTIMATE liability for security - it can never be delegated down to IT or the CISO. This Domain 1.3 deep-dive separates governance from management, then walks every role on the org chart and the control frameworks the exam keeps testing.

With Emma, Erica, River, and Liam, we cover the governance foundations the heaviest domain on the current exam is built on, and the question-reading habits that turn role and framework scenarios into a quick, defensible decision. You will learn why the data owner decides while the custodian implements, which framework fits which job, and how due diligence and due care become your legal shield through the prudent person rule.

In this video:

• Governance versus management, and aligning security to the business mission
• The business events that trigger a security review: acquisitions, mergers, divestitures
• Who holds ultimate liability, and where the CISO actually fits
• Data owner versus data custodian, the pair candidates confuse most
• ISO 27001 and 27002, COBIT, SABSA, PCI DSS, the NIST CSF, and the RMF
• Due diligence versus due care, and the prudent person rule that grades both

The next video in the series moves into compliance and the legal and regulatory requirements that put real teeth behind governance. Anchored to the (ISC)2 CISSP Detailed Content Outline effective April 15, 2024.
