The goal of any security system is to permit only the movement that you actually want of people, assets, or data within your facility. That principle remains the same whether it’s officers and inmates in a corrections facility, mobile devices with sensitive data at a power plant, or forklifts in a warehouse.
A proper Enterprise Security Strategy requires end-to-end execution, relying on a wide range of different access control and security systems integrated together. The challenge is cover any possible breaches, while being flexible as trends change. Rather than using brute force or expensive tactics, you should focus on carefully integrating all parts of your system so that there is no opportunities for malicious activity to take place. A carefully planned, fully secure system will save you more money in the future in the event you have a knee-jerk reaction to correct a problem when it's already too late.
