A Contract for Difference (CfD) is a financial agreement that stabilizes revenue by paying the gap between a market price and an agreed strike price. If market prices fall below the strike price, the contract pays the seller the difference; if prices rise above it, the seller repays the excess. This makes long-lived infrastructure easier to finance because lenders can model predictable cash flow instead of exposing the project entirely to volatile prices.
In cyber security, CfDs matter because they depend on accurate metering, pricing, and settlement data. Attackers may target billing systems, market interfaces, or contract records to distort payments, create fraud, or disrupt confidence in the project. Defenders need strong access control, audit logs, data integrity checks, and segregation between operational systems and financial settlement systems. In critical infrastructure projects, a compromised CfD platform can become a business risk even when the physical asset is untouched.
