A security officer is like a grown-up helper who makes sure that everything is safe and secure for people. They are like superheroes who protect the people from bad guys who might try to steal things or harm others.
Security officers work in places like banks, schools, airports, and malls to make sure that everyone is safe. They check bags and make sure no one brings harmful things to these places. They also monitor cameras and walk around to check for any signs of danger. They even help people who might be lost or need assistance.
Think of security officers as your watchful and helpful friends who are always looking out for you and keeping you safe wherever you go.
