Is it necessary to have work experience or a job role before applying for masters in cyber security for a Master's/Bachelor's?

No, work experience is not mandatory for most master's programs in cybersecurity. Many universities accept fresh graduates, especially if you have a relevant bachelor's degree like computer science.

However, work experience can strengthen your application and may be required for specific programs or if your academic background is less directly related. Some universities allow professional experience to compensate for missing academic prerequisites.
