Information system security officers establish and enforce security policies to protect an organizationâs computer infrastructure, networks and data.
Security officers are not required to make arrests, but have the authority to make a citizen's arrest, or otherwise act as an agent of law enforcement, for example, at the request of a police officer or sheriff. A private security officer's primary duty is the prevention and deterrence of crime. Security personnel enforce company rules and can act to protect lives and property, and they often have a contractual obligation to provide these actions.
