K-12 security by the numbers


Schools should be a safe place, fostering a sense of security among students and faculty. Controlling access is a critical part of a school’s efforts to provide a safe learning environment. It begins with a secure perimeter—from the main entrance and beyond, to all secondary entrances and tertiary openings. Know the potential risks facing K-12 schools today and get started on a comprehensive security plan with a few key steps.

Assess threats and vulnerabilities.

There are a number of free self-assessment tools available to help you prioritize security initiatives based on: Criticality, vulnerability, probability.

Consider the security of your facility in totality.

It is common for the majority of available security funds to be focused on the most visible points of entry, leaving secondary doors vulnerable due to cost constraints.

Implement a layered security approach.

Layered security works from the outside in to protect critical assets. As one layer is bypassed, another layer provides an additional level of protection.
