安全原则:人类,网络和生物

Principles of Security: Human, Cyber, and Biological

Blake C. Stacey, Yaneer Bar-Yam

摘要:

网络安全攻击是全球经济和社会系统的一个重大且日益沉重的负担。在这里,我们分析了不同领域的安全原则,并展示了当前网络安全的架构缺陷。网络安全本质上是脆弱的,因为它缺乏保护整个系统而不是单个计算机的能力。当前的体系结构使计算机网络中的所有节点能够透明地相互通信,因此安全性将需要保护网络中的每台计算机免受所有可能的攻击。相比之下,其他系统依赖于系统范围的保护。在提供常规安全时,警察巡逻社区,军队保护边界,而不是保卫每个家庭。同样,在生物学中,免疫系统主要通过对皮肤、膜和血液的作用来抵御病毒和细菌,而不是要求每个细胞进行自我防御。我们建议将这些原则应用于应对网络安全挑战。这将需要:(a)使自我传播的安全软件能够广泛传播,并为这种安全软件建立一个开发者社区,(b)修改互联网路由器的协议,以适应可调节互联网流量的自适应安全软件。对免疫系统架构的分析提供了许多其他应该应用于网络安全的原则。在这些原则中,有一个是检测和行动的仔细相互作用,包括进化改进。然而,通过应用这些原则来实现显著的安全收益在很大程度上取决于补救底层架构限制。

英文摘要:

Cybersecurity attacks are a major and increasing burden to economic and social systems globally. Here we analyze the principles of security in different domains and demonstrate an architectural flaw in current cybersecurity. Cybersecurity is inherently weak because it is missing the ability to defend the overall system instead of individual computers. The current architecture enables all nodes in the computer network to communicate transparently with one another, so security would require protecting every computer in the network from all possible attacks. In contrast, other systems depend on system-wide protections. In providing conventional security, police patrol neighborhoods and the military secures borders, rather than defending each individual household. Likewise, in biology, the immune system provides security against viruses and bacteria using primarily action at the skin, membranes, and blood, rather than requiring each cell to defend itself. We propose applying these same principles to address the cybersecurity challenge. This will require: (a) Enabling pervasive distribution of self-propagating securityware and creating a developer community for such securityware, and (b) Modifying the protocols of internet routers to accommodate adaptive security software that would regulate internet traffic. The analysis of the immune system architecture provides many other principles that should be applied to cybersecurity. Among these principles is a careful interplay of detection and action that includes evolutionary improvement. However, achieving significant security gains by applying these principles depends strongly on remedying the underlying architectural limitations.
