- The cyber threats to the United States Infrastructure are increasing at an alarming rate, especially targeting vulnerable platforms like IoT, OT, and ICS.
- Law enforcement agencies have stepped up to counter these threats and some cases of successful hacker campaigns have been reported against U.S infrastructure.
- Proactive security management of cyber-physical systems is proposed as the most effective solution to neutralize these threats.
We stand on the precipice of a digital revolution of unprecedented scale, witnessing a sweeping metamorphosis that reshapes our communication frameworks, work dynamics, and even urban infrastructures. While it is rich with potential benefits, one cannot overlook its more ominous implications, namely, the daunting surge in cyber threats. This dimension of risk is particularly palpable in the realm of cyber-physical systems (CPS), a nuanced amalgamation of cutting-edge digital and physical components, spanning industrial control systems and large-scale IoT.
Platforms like IoT, OT, and ICS, critical intersections of digital and physical domains, are increasingly susceptible to cybersecurity threats. However, adopting a lens borrowed from Modern Portfolio Theory (MPT), a fresh narrative emerges for the denizens of Wall Street. Through the prism of MPT, as espoused by Harry Markowitz, cybersecurity can be extrapolated as an investment in a portfolio diversification strategy, aimed at diluting unsystematic risks. From this perspective, it's worth noting that projections from Cybersecurity Ventures predict global cybercrime costs spiraling to $10.5 trillion per annum by 2025; translating into an alarming 15% growth rate each year over half a decade.
Prominent drivers of this vulnerability include the mushrooming use of mobile devices and adoption of 5G. Projections estimate a staggering 41.6 billion IoT devices by 2025, consequently expanding the surface terrain for cybersecurity incursions. Drawing upon Bernoulli's Utility Theory's principles, it is evident that the proliferation of smart device usage parallels heightening risk metrics. This confluence underscores the urgency for a robust discourse on future threat mitigations.
