Security Foundations & Threat Landscape
The ground truth every security role builds on: the CIA triad made practical, attacker motivations and kill-chain thinking, common attack classes, defense-in-depth, and security's place in the SDLC — taught through walkthroughs of real (public) incidents so concepts attach to consequences.

Roles this course serves
This course is authored to band B1.
Every course we run is written to one rung of the CASI ladder, so a plan can be assembled to take a team from where they are to where they need to be.
What do B1–B6 mean?The CASI Capability Ladder — click to expand
Every course targets a band on the CASI Capability Ladder — our six-band proficiency scale, anchored to open standards (O*NET, ESCO, NICE, NIST AI RMF, Bloom's). A band tells you how deep a course goes, and what evidence proves it.
A note on B6. Courses in this catalog target B1–B5. B6 is not taught — it is recognised, through a portfolio and a panel, once someone is setting direction for others. Every journey here is built to land a learner at B5.
