Is this course right for you?

Our take
Keith Watson's Pluralsight course walks through the foundations of protecting an organisation's information assets.

Good for: A conceptual grounding in information-security fundamentals.

Skip if: You want hands-on technical security or you already work in security.

It covers the CIA triad, governance and risk management, compliance frameworks and security controls — the conceptual scaffolding the whole field is built on, before any specific tool. That makes it a genuinely useful grounding for people entering security or anyone who needs the fundamentals to make sense of the rest, since these ideas are what everything technical later hangs off.

It's deliberately conceptual, so skip it if you want hands-on technical security or you already work in the field. It's on a Pluralsight subscription (Standard about $29/month or $299/year, Premium about $45/month or $499/year, 10-day trial). Security fundamentals like the CIA triad don't change (as of 2026).

About this course

Keith Watson walks through the foundations of protecting organizational information assets: confidentiality, integrity, and availability (the CIA triad), governance and risk management, compliance frameworks, security controls, auditing/monitoring, and incident management and disaster preparedness. It also frames how these pieces fit into a real security programme, so the vocabulary connects to how organisations actually organise their defences.

Frequently asked questions

It is the foundation of information security: Confidentiality (keeping data private), Integrity (keeping it accurate and unaltered), and Availability (keeping it accessible when needed). Nearly every security concept maps back to protecting one of these three properties. The course uses it as the organising framework, so you understand security not as a list of tools but as defending confidentiality, integrity, and availability.

People new to information security wanting a solid conceptual foundation — aspiring security professionals, IT staff, or anyone needing to understand the field's core ideas. It assumes some general IT familiarity but not security expertise, so it works as an entry point. It is an introduction, so experienced security practitioners would find it basic; its strength is grounding newcomers in the fundamentals.

Not especially — it is a concepts-and-principles course introducing how information security works, its core ideas, and the vocabulary, rather than a hands-on labs course. That fits its role as an introduction. If you want practical, tool-based security skills, you would follow it with hands-on courses; this builds the conceptual foundation that makes those later, practical topics make sense.

Yes. Pluralsight offers a free trial (commonly around ten days), enough to work through an introductory course like this at no cost if you are disciplined. Beyond the trial it is a subscription, so ongoing access to this and Pluralsight's deeper security courses is paid — the trial lets you sample it before committing.

Pluralsight issues a course completion record rather than an industry certification. Recognised security credentials — like CompTIA Security+ or CISSP — are earned separately through their own exams. Treat the completion as a marker of learning; the real value is the conceptual foundation it gives you before pursuing those certifications or deeper, hands-on security study.
