Short Answer 
The answer outlines three key steps to enhance physical security: (1) understanding and implementing barriers like fences and walls to deter unauthorized access, (2) using Intrusion Detection Systems to monitor for suspicious activity, and (3) employing trained security personnel to patrol and respond to potential threats. Each step contributes to creating a robust security framework.
Step 1: Understand Barriers
Barriers are essential physical measures designed to restrict or control access to an area. They serve as the first line of defense against unauthorized entry. Common types of barriers include:
- Fences
- Walls
- Other obstructions
These elements work to deter potential intruders and provide a basic level of security.
Step 2: Implement Intrusion Detection Systems (IDS)
Intrusion Detection Systems play a vital role in enhancing security by monitoring for unauthorized activity. These systems can detect unusual movements and send alerts to personnel about potential breaches. Different types of IDS include:
- Simple motion sensors
- Advanced systems integrated with surveillance cameras
Such systems help in promptly identifying and responding to security threats.
Step 3: Employ Security Forces
The presence of trained personnel is crucial for effective physical security. Security forces are responsible for protecting the site by patrolling and monitoring for any suspicious activities. This can include:
- Security guards
- Police officers
These individuals respond to security breaches, adding an essential layer of protection to your security strategy.
