Reconciliation of Privacy with Preventive Cybersecurity: The Bright Internet Approach The emergence of a preventive cybersecurity paradigm that aims to eliminate the sources of cybercrime threats is becoming an increasingly necessary complement to the current selfdefensive cybersecurity systems. One concern associated with adopting such preventive measures is the risk of privacy infringement. Therefore, it is necessary to design the future Internet infrastructure so that it can appropriately balance preventive cybersecurity measures with privacy protections. This research proposes to design the Internet infrastructure using the preventive cybersecurity measures of the Bright Internet, namely preventive cybersecurity protocol and identifiable anonymity protocol, and ten privacy rights derived from Europexe2x80x99s General Data Protection Regulations (GDPR). We then analyze the legitimacy of the five steps of the preventive cybersecurity protocol and the four features of the identifiable anonymity protocol from the perspectives of ten privacy rights. We address the legitimacy from the perspective of potential victimsxe2x80x99 selfdefense rights. Finally, we discuss four potential risks that may occur to the innocent senders and proposed resilient recovery procedures.

Assurance for CyberSecurity with AssumeGuarantee Reasoning Design of cybersecurity solutions for a network is a challenging problem as it involves the integration of several complex components such as routers, servers, computers, smart devices, that include not only essential networking algorithms but also security algorithms. This is further complicated by the need to have robust security policies implemented to prevent violation of confidentiality as the networked devices interact. The design of such complex networked systems demand a more rigorous approach to the modeling and analysis at a higher level of abstraction, which can be inherited from the field of formal methods in software engineering for safety critical systems. Presently, network or security engineers do not use a formal method based software engineering approach to design and build cybersecurity systems. Thus, we propose a software engineering based formal approach to model and analyze cybersecurity, that along with identification of concrete requirements enables automated analysis to guarantee cybersecurity properties are satisfied within the network. In this research paper, we discuss an ontology guided assumeguarantee based formal approach to model and analyze a designed network. To enable this approach, a domain specific language is designed that allows association of assumptions with components in the network that allows verifying the satisfaction of contracts that are guarantees. The formal language designed includes reserved words are guided by the CyberSecurity domain and the semantic reasoning is based on formal architectural representation.
