ROI / Cost Analysis Information
Data is the backbone of your organization. You need to have a solid network security plan. The first step in developing this plan is to perform a risk analysis where you identify which assets are worth protecting and what they need to be protected from.

Ranking the risks by level of severity and assigning value to your assets is also part of this process. In general, the cost of protecting a particular asset should not be more than the asset itself. Compiling a list of both tangible (servers, routers, etc.) and intangible (software, data, etc.) and the cost to replace the asset must be made to prioritize your assets as you prioritize risk.

Key Considerations
Determining the threats against the assets requiring protection is the next step. Some threats to think about are:

Unauthorized Access
 Denial of Service
 Data Corruption
 Information Leakage
 Theft
 Natural Disaster
 Product Depreciation

A thorough risk assessment and a ROI / cost analysis of your most valuable and most vulnerable assets is crucial. This analysis and understanding will be valuable in developing your network security policy.
