Where it might lead
Examples to explore, not guaranteed jobs. Skills, location, experience and qualifications affect entry.
- Security analyst
Apply secure coding to practical problems; build a small project and look for supervised entry-level experience.
Possible settings: industry teams, consultancies, public organisations and research groups.
- Security engineer
Use cryptography to evaluate options and explain findings to others; practise research and clear communication.
Possible settings: industry teams, consultancies, public organisations and research groups.
- Digital forensics analyst
Pursue a research or professional training route. Independent research and regulated practice often require further study and specific qualifications.
Possible settings: industry teams, consultancies, public organisations and research groups.
Experience before deciding
Make a threat model for a fictional school app
About 90 minutes of active work, within seven days of starting.
- Spend 20 minutes learning the basics of secure coding from an official university course or open educational resource.
- Make a threat model for a fictional school app
- Ask a willing peer for feedback, then record one engaging part, one difficulty and one question.
Output: One page or small prototype showing your method, result and limitations.
Use public examples or a paper simulation if tools, interviews or equipment are unavailable. No spending is required.
