How should we approach the development of cyber-policy and -infrastructure given the “short arm” of predictive knowledge? That is the question being asked today and this post will answer that. To start we will be answering what the “short arm” is. The “short arm” of predictive knowledge refers to the viewpoint and ethical conduct of each situation being immediate, and, as there is no way to omnisciently know the future repercussions of the decision made, there is no way to evaluate the shortcomings of said decision. As we approach the development of cyber policy and cyber infrastructure, we will not be able to see the future so this lack of omniscience must be taken into consideration. We also must take care of policies and infrastructure. Policies and infrastructure must be consistently evaluated and improved in order to remain physically sound, to prevent unnecessary breaches, as well as ethically sound, to ensure the well-being of those reliant upon the infrastructure is taken into consideration. A good cyber policy sets the standards for the acceptable behavior within the cyber landscape for actions such as encryption or use of social media. By consistently improving cyber policies, ease of use and safety for users is being improved. There are clearly set boundaries which deter threats, both exterior and insider, as well as privacy implications by design. As vulnerabilities are discovered and potentially exploited, there will be made available opportunity to improve policies in order to provide greater protection. If this opportunity is not capitalized upon, the ethics of the situation must be called into question. Developers owe it to consumers to continuously update and improve their product. All in all, we should approach the development of cyber policies and infrastructure with a clear goal in mind. We should make sure to be careful considering the “short arm” of predictive knowledge.
