Optimizing Cybersecurity Investments over Time

In the context of growing vulnerabilities, cyber-risk management cannot rely on a one-off approach, instead calling for continuous re-assessment risk and adaptation strategies. Under mixed investment–insurance where both mitigation transfer are employed, implies re-computation optimal amount to invest in security over time. this paper, we deal with problem computing balance between investment insurance payments achieve minimum overall expense when vulnerability grows time according logistic function, adopting greedy strategy is carried out periodically at each epoch. We consider three liability degrees, from full partial deductibles. find that represents by far dominant component mix may be relied as single protection tool very low.
