What type of duty does a security officer have when on a fixed post?

A security officer on a fixed post primarily has the duty of protection. This means they are responsible for safeguarding the property, personnel, and assets within their designated area. The role involves maintaining a visible presence to deter potential threats and responding to incidents that may arise. While observation and communication are also important aspects of a security officer's responsibilities, the overarching duty is to ensure safety and security, which aligns with the protective nature of their role. Therefore, the fixed post provides an opportunity for the officer to fulfill their obligation to protect by monitoring for any suspicious activity, ensuring compliance with security protocols, and taking action when necessary.
