Before implementing any security measures, it's crucial to identify potential weaknesses. This involves analyzing the specific risks faced based on factors like location, type of assets, and potential threats. This assessment forms the foundation of a tailored security plan, ensuring resources are allocated efficiently.

No single security measure is foolproof. The book emphasizes a layered approach, combining physical barriers like fences and walls with technological solutions like surveillance systems and alarm systems. This multi-layered strategy creates a complex web of security, making it significantly more difficult for intruders to penetrate.

Technology plays a crucial role, but the human element remains paramount. The book underscores the importance of trained security personnel, emphasizing their role in monitoring systems, responding to incidents, and making critical decisions. It also highlights the need for security awareness among employees, encouraging vigilance and proactive reporting of suspicious activities.
