Justifying the Expense of IDS, Part Two: Calculating ROI for IDSAdded by Papergrl
Description:

To this end we introduced the Cascading Threat Multiplier (CTM) to expand on the Single Loss Expectancy (SLE) equation. We also reviewed implementation and management costs based on various support profiles and reviewed the commonly accepted risk equations. Finally, we left off with the basic formula for calculating ROI for security, otherwise commonly known as Return on Security Investment (ROSI).
