I ran across a great tool by MikroTik which will map your network and then provide service level monitoring and alerts all for free. Check this out in the "Free Security Tools" > "Network Tools" section.
This is a PowerPoint presentation that covers issues when creating a security policy and the different components of the policy. This is a longer presentation than the executive version and covers more in-depth details of how to create a policy. I will be adding additional documents to this section that will provide guidelines for security categories and numbering system.
The file is a PowerPoint presentation that is targeted for high level executives and covers the basic principals of why a security policy is needed and how the approval structure should be organized. This is a very short presentation for non-technical and short attention span audiences.
