Security guards may be armed or unarmed. Armed guards are often paid more money. In some states, a license is required in order to work as a security professional, and there may be additional licensing required to carry weapons.
In most cases, the security company provides equipment, uniforms and badges, but the employee may be obligated to pay for the uniform. Security responsibilities vary according to the client. For example, a bank commonly hires personnel to accompany money and valuables. Working at a mall or museum, however, is likely to involve a lot of time simply patrolling, usually on foot. Hospital security is also important. Marine security officers may work at ports or even on cruise ships. In all of these situations, one of the primary responsibilities of security personnel is preventing theft. Some workers may specialize in event security, either working for a convention center or traveling to various conventions and conferences.
A gated community association, on the other hand, often hires security to control access to the grounds. The work may consist of patrolling or watching entry points.
Airport security is administered at most airports by the TSA. Museums and Federal buildings may also have airport style checkpoints. Airport security personnel operate scanners and other gear intended to detect contraband items.
Bodyguards protect individuals. Personal protection is provided by a specialist company or by the government. Bodyguards may be required to travel, even internationally, and in some cases may work in war zones and other high risk areas.
A security job agency operates much like other employment agencies, also employing human resources professionals, and secretarial staff. Management personnel are also hired by security companies. A private security agency may offer both corporate and home protection, or specialize in one or the other.
Most private security professionals undertake a duty which is tedious, but essential.
