Practical cybersecurity guides, labs & compliance
Choose a vulnerable lab from prerequisites, the task and the skill gap you want to practise. Record the source and context of a difficulty label, distinguish setup friction and assistance, and update the choice from your own evidence.
Build a practice catalogue with separate source, image, boot, exercise and reproduction checks. Date each verified field, preserve unknowns and release identity, and keep a public reading list distinct from vulnerable runtime environments.
Build a free-lab practice plan from learning gaps, compatible images and a controlled environment. Separate VM releases from web-app exercises, include setup costs and use the schedule estimator as an assumption-based planning aid.
