Executive Summary
The way to get the executive team to pay attention is to provide a quality ROI on any new initiative. If the Boards of Directors can’t understand the needs of various departments then the only way to their pocketbook is to present them with a bottom line return on their investment.
In the case of procuring a security budget executives are often less than forthcoming because of the lack of information they receive from department heads. Boards of Directors and executive teams respond most favorably to requests for information security budgets which are cost justified with a simple ROI business case.
The business case needs to specifically show how potential costs associated with liability, caused by security breaches, may be minimized by implementing a sound security infrastructure. This can be accomplished by allowing a third party to do a security audit that provides evidence of security risks.
This approach of utilizing an ROI to cost justify a security budget is the same premise used to purchase insurance for commodities like office furniture, computers, etc. The difference is that if a security breach occurs as a result of not implementing the proper protection procedures, the associated costs far outweigh the costs to replace furniture.
The potential liabilities, such as loss of production and/or loss of reputation are translated into actual dollars in the ROI. The security budgets are created by taking a small percentage of the cost of the potential losses and applying it to preventative measures.
As such this calculation of ROI is actually a calculation of the % of the cost to avoid the cost of liability compared to the potential cost of liability. This is similar to the methodology for calculating the financial benefit of insurance for commodities such as office buildings, furniture and computers. [1]
Since the cost of a security infrastructure often falls within about the same price ratio of commodity insurance, one would think this cost justification would be easily sold to an executive committee.
This is often the case, particularly when the business risks identified in the business case are based upon hard evidence of actual security risks. Actual security risks can be identified by evidentiary security audits. These audits are performed by impartial third parties, with an expertise in identifying both technical and policy risks.
[1] Typical annual insurance rates for commodities are about 1.5% – 2.5% of asset replacement cost. The author has observed (over many business cases) that annual security budgets can similarly be about 2% – 4% of potential security breach related costs.
My next blog will focus on the Methodology of Calculating ROI.
Have a secure week.
