As part of your DISP membership you are required to deliver a security awareness program on an annual basis, to your staff.
Below is an example, created by Defence, that can be used and tailored to suit your operational environment.
Along with providing security awareness training, you are obliged to develop your own insider threat awareness training to provide to your staff.
The Organisational Resilience webpage hosts an insider threat personal security handbook. This handbook outlines how you can make your business more resilient by understanding the threat posed by trusted insiders, assist you in evaluating those risks, and helps to develop a personnel security framework.
It is recommended that you use this handbook to inform the development of your own Insider Threat Awareness program.
