“…The concept of antifragility has been actively applied in numerous areas such as risk analysis [2,3], physics [4], molecular biology [5,6], transportation planning [7,8], engineering [9,10,11], aerospace and computer science [12][13][14][15]. However, a practical measure of antifragility has not been developed yet.…”

Antifragility is a property that enhances the capability of a system in response to external perturbations. Although the concept has been applied in many areas, a practical measure of antifragility has not been developed yet. Here we propose a simply calculable measure of antifragility, based on the change of "satisfaction" before and after adding perturbations, and apply it to random Boolean networks (RBNs). Using the measure, we found that ordered RBNs are the most antifragile. Also, we demonstrated that seven biological systems are antifragile. Our measure and results can be used in various applications of Boolean networks (BNs) including creating antifragile engineering systems, identifying the genetic mechanism of antifragile biological systems, and developing new treatment strategies for various diseases.

“…Many published principles [2,5,7,11,51,52] provide foundations for various aspects of antifragility (see [5,7,11] for examples). Although this paper's author has only discussed principles for antifragility to downtime, the presented principles are valid for other types of antifragility, including antifragility to malware attacks [2].…”

“…The literature discusses many types of antifragility in, for example, cybersecurity [3][4][5], software [6][7][8], complex adaptive systems [9][10][11] and biology [12]. However, the current tutorial focuses solely on avoiding downtime in socio-technical systems that change over time.…”

An antifragile system of software and stakeholders, including designers, developers, and operators, learn from incidents how to avoid outages and maintain high uptime. This tutorial article reviews how to design and operate such socio-technical systems with antifragility to downtime. It documents the importance of four design principles and two operational principles by exploring the polar opposite anti-principles and the interplay between the principles and the anti-principles. The design principles mandate a software design of separate and isolatable processes with sufficient diversity and redundancy. The processes should communicate asynchronously over an external network. The operational principles imply that the software development teams should repeatedly inject artificial failures into the production system to understand its behavior and detect and mitigate vulnerabilities as the system and its environment change.

“…Other works also cover system designs (Chapter 10 in [11]) and [12]. Buinevich et al [13] provides an account related to IoT systems and Monperrus [14] provides principles for antifragile software development. There are a couple of papers on security architectures for mobile systems [15,16], which are relevant.…”

Digital systems are almost always vulnerable, yet we increasingly depend on these systems. There will be many threats towards these system. In a fully networked system, the vulnerabilities will literally be exposed to the whole world. The exposed vulnerabilities may be transformed into attacks. To counter this state of "vulnerability", the standard remedy is to conduct security requirements analysis and security threat modeling. Threats are assessed, and various countermeasures are devised. The totality of these measures may be described as a security architecture. The goal of a security architecture will largely be to make the system robust and resilient in the face of an adversary. However, we shall argue that this is not enough. Security architecture designs should go one step further, and actually improve the defenses when faced with hostile actions. That is, the security architectures must become antifragile.
