Application Security & Secure Coding
Write and review code attackers can't easily bend: the OWASP Top 10 taught by exploiting then fixing each class in a deliberately vulnerable app — injection, broken auth, access-control flaws, SSRF and friends — plus the code-review checklists that transfer the skill to daily work.

SEC-303 in the role journeys.
This course appears in 4 of our 45 role journeys. Here is what a learner takes immediately before and after it in each.
Roles this course serves
This course is authored to band B3.
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.
