When you've finished making your list of statements from the Checklist which were answered in the negative, review it and determine approprate responses. Please take into consideration your departmental inventory, the information assets you are protecting and the level of protection you should have. Consider any problems you would have whether they are legal problems, support issues, availability or any other evils that might beset your department.
Remember to consider the recommended security additions in the Risk Assessment based on the categories of confidentiality, integrity and availability. Add these to issues/statements from the Security Checklist which you have decided to improve or implement. Include your inventory (which will come in handy for future reference and possible insurance claims) in the beginning of the report.
Make an effort to understand your systems and your department. The systems administrator may develop the plan to have approved by the Dean/Director/Administrator. The departmental Systems Administrator and Dean/Director/Administrator should discuss issues, possibilities, time lines and develop a realistic plan. Responsibilities for every part of the plan should be determined and assigned. Target dates should also be set.
The Departmental Security Plan should be reviewed annually. The Plan should be monitored with progress reports provided to the Dean/Director/Administrator quarterly.
Sample Security Plan
In developing a Departmental Security Plan the Asset Inventory and Risk Assessment should be considered. The following Sample Security Plan is for a department that has evaluated itself as needing a highly secure environment. This department's system rated high in all areas (confidentiality, integrity and availability) of the Risk Assessment. The Asset Inventory is also listed below.
(Statements on this template have been gleaned from the Departmental Security Checklist. All items answered 'no', should be addressed in the Security Plan.)
According to the Risk Assessment the Sample department scored in the high probability and high impact areas for all categories (confidentiality, integrity and availability).
The following is an inventory of the physical and information assets of the Sample department:
Social security numbers
Sample Security Plan
All of the following bulleted items were marked 'no' on the Security Checklist. The Sample department is taking corrective action as indicated by the statements with target dates. The items should be discussed between departmental administration (Dean, Director, Administrator) and the Systems Administrator (UCS, Computing Manager) to determine if there is a need to consider these as possible deficiencies and implement additional security processes, policies or improvements based on the Asset Inventory and Risk Analysis.
Please also consider if your current infrastructure is sufficient condition to support additional measures.<
