本文提供的演示文稿，在一个综合的方式，一系列的结果，解决的后果，在一个生态系统中的信息管家的存在下攻击，并建立适当的防御性投资的反应，从而允许在各种攻击环境中的信息管家的性质的凝聚力的理解。我们确定的信息安全和攻击强度的投资水平时，代理商的反应在一个非协调的方式，并将它们的情况下，系统的协调响应下进行的指导下管家。我们表明，只有在最精心设计的机构设置的存在，消息灵通的管家提供了一个系统的弹性攻击的增加。在这种情况下，管理员及其政策工具所能获得的信息都被削减了，协调的政策反应不会给个体代理带来额外的好处，在某些情况下，它们实际上不如原子反应。系统的可持续性确实在管理员的存在下得到了改善，这阻止了攻击者并减少了攻击的数量和强度。在大多数情况下，生态系统中的代理人所承担的投资支出超过了帕累托有效的程度。
This paper provides for the presentation, in an integrated manner, of a sequence of results addressing the consequences of the presence of an information steward in an ecosystem under attack and establishes the appropriate defensive investment responses, thus allowing for a cohesive understanding of the nature of the information steward in a variety of attack contexts. We determine the level of investment in information security and attacking intensity when agents react in a non-coordinated manner and compare them to the case of the system’s coordinated response undertaken under the guidance of a steward. We show that only in the most well-designed institutional set-up the presence of the well-informed steward provides for an increase of the system’s resilience to attacks. In the case in which both the information available to the steward and its policy instruments are curtailed, coordinated policy responses yield no additional benefits to individual agents and in some case they actually compared unfavourably to atomistic responses. The system’s sustainability does improve in the presence of a steward, which deters attackers and reduces the numbers and intensity of attacks. In most cases, the resulting investment expenditure undertaken by the agents in the ecosystem exceeds its Pareto efficient magnitude.
