A cyber security volunteer helps prevent hacking and other security breaches from occurring in an organization. In this career, your responsibilities are to monitor the activity of a network to identify any unauthorized access or other suspicious activity, such as a denial-of-service threat that could shut down an entire system. Additional duties involve installing software on a computer that can automate these tasks, conducting a penetration test for prevention, and reporting a violation if it happens. Positions exist with non-profits, schools, government, and any other group that has an online presence.
