Security Job Responsibilities


Security guards are trained professionals hired by individuals and private organizations to prevent crime and to safeguard their persons and property. Although not an official member of law enforcement, security guards have duties similar to that of police and share a common interest in upholding the law. Specific duties of security guards differ depending on the employee.


  • Like many law enforcement officials, security guards are required to patrol the grounds over which they have responsibility, such as an office building, a private residence, or a college campus. While on patrol, the guard will maintain order and look out for irregularities.

Investigate Irregularities

  • Security guards are generally responsible for investigating all irregularities that come to their attention, such as after being notified a visitor or through the activation of an alarm. The guard should try to determine the cause of the irregularity and then take appropriate action.

Maintain Security Systems

  • Security guards must also maintain all security systems, including burglar and fire alarms, motion detectors, and anti-theft devices. This includes turning on the systems when required and keeping them in proper working order.

Notify Visitors of Rules

  • Security guards are also expected to apprise visitors of appropriate rules of conduct. This can include areas that are off-limits, dress codes, and inappropriate behavior. The guard should also make clear the consequences of violating these policies.

Apprehend Violators

  • If a person has violated a law within their jurisdiction, it is generally the responsibility of the security guards to apprehend them, using force if necessary. For this reason, most guards are generally required to receive training in the use of force, as well as laws governing private apprehensions.

Notify Police, Fire Department, and Medical Personnel

  • In the event of a crime, a fire, or a medical emergency, the security guards should notify the relevant municipal agency and provide them assistance if required.

Control Building Access

Check Packages

  • Security guards will often inspect packages or parcels entering and exiting a building to prevent the admittance of weapons and to limit theft.

Write Reports of Activities

  • At the end of each shift, most security guards will submit a written report detailing their activities and any events of importance that occurred.
