    Government informatization has gradually moved from electronic and computerized information, to networked government information, and government big data (GBD) is a new stage in government informatization development. This stage features openness, sharing, dynamic, real-time and intelligence. In view of these features and the current situation of government big data development, this paper analyzes the technical and managemental challenges and basic security principles of the GBD platform development. Based on analysis, this paper proposes a new kind of reference architecture for GBD security based on an appropriate management organization structure. The paper also reviews related security regulatory mechanisms and security measures of this architecture. Compared to the US government's national institute of standards and technology (NIST) big data reference architecture, the proposed architecture is simpler, has a higher security level, clearer functional requirements, and is easier to implement. The proposed architecture can meet the actual current needs of big data security management, and has practical value in guiding the future government cloud platform, and security design and regulation of the GBD system.

    Cyber-attacks are the use of network vulnerabilities and security flaws to attack the hardware, software and data of a cyber system. The earlier a cyber-attack is identified, the less adverse effect it has. The traditional network intrusion detection system (IDS) has some limitations in detecting cyber-attacks, such as passive protection and limited capability of threat identification. Threat intelligence technology provides a more scientific and effective method for identifying potential or actual cyber-attacks by using big data analysis,and provides a comprehensive and relevant cyber-attack defense model.

    With the advent of the era of big data, information systems have exhibited some new features, including boundary obfuscation, system virtualization, unstructure and diversification, and the low coupling degree of function and data. These features not only lead to a big difference between big data technology (DT) and information technology (IT), but also promote the upgrading and evolution of network security technology. In response to these changes, in this paper we compare the characteristics between IT era and DT era, and then propose four DT security principles: privacy, integrity, traceability, and controllability, as well as active and dynamic defense strategy based on “propagation prediction, tracking audit, dynamic management and control”. We further discusses the security challenges faced by DT and the corresponding assurance strategies. On this basis, the big data security technologies can be divided into four levels: “elimination, continuation, improvement, and innovation”, and we provide analyzation, combination and explaination for these technologies according to six categories: access control, identification and authentication, data encryption, data privacy, intrusion prevention, security audit and disaster recovery. These results will offer important assistance for the evolution of security technologies in the DT era, the construction of big data platform, the designation of security assurance strategies, and technology suitable for big data.

    The extensive collection and use of personal data in the information society has threatened and damaged the rights of data subjects, and a right is urgently needed to strengthen the status of data subjects and the autonomy of individuals to data. The European Unions General Data Protection Regulations give data subjects a series of data rights, among which the establishment of right to erasure has attracted extensive attention from the legal profession and the Internet. Data subjects can apply for deletion of relevant personal data links under certain conditions. Whether it is based on the personal data protection in China, or in order to deal with the EU data legally and reasonably, it is necessary to have a thorough understanding of right to erasure and to sort out the ways of right remedy. This paper mainly discusses the nonlitigation remedy mechanism of right to erasure. Data subjects can get timely and adequate remedy of rights through the network platform and administrative agencies. The introduction of the relevant provisions of right to erasure should clearly define the conditions and scope of the exercise of rights, as well as the benefit measurement with freedom of speech and the protection of the data industry.

    The identity of users in cyberspace is virtual and difficult to determine, which makes it difficult to effectively manage the disordered state of cyberspace virtual society. The Internet real-name system is an Internet management method based on the real name of the user. It is an important means and system for restraining, guiding and protecting Internet users. However, with the arrival of big data era, more and more information exist in the cyberspace, and personal information leakage incidents are common. The Internet identity management system based on the Internet electronic identity (eID) can ensure that the Internet service agencies can effectively identify users' real identity without disclosing their personal information, which provides a good solution to the conflict between the Internet real-name system and personal information protection. At present, China's Internet electronic identity management is still in the preliminary development and pilot application stage, and relevant legal system is still not perfect, which must be explored.
