In data handling, security and privacy are essential for database administrators and users that own their information. Information about security models or architectures was analyzed for databases that minimize Cyber Attacks. The problem is that security models deployed in databases in public organizations suffer from computer attacks due to vulnerabilities in their security management systems. Data providers often publish the information for research purposes, publishing compromises on the privacy of the data of users registered in the entities. There are many security techniques for databases based on data encryption processes in transactions, however, the techniques found compromise information. The development of the document used the deductive method and exploratory research technique that allows us to study the information in the articles presented. In this document we have proposed a Security Model Assessment Prototype for Databases, a Prototype of Security Management Architecture in Blockchain for a Database, a Database Security Algorithm, a Logical Structure of the Management System in Blockchain, and a Prototype to mitigate cyberattacks. The use of a hybrid blockchain model provides the system with the optimal security that public organizations in relation to test results performed with a 99.50% security effectiveness. The simulations presented in this document were conducted based on in-depth studies and the data were randomly placed with a range according to the study results based on real-world situations.

The availability of information generated on a large scale has allowed sharing without considering the levels of risk that can be caused by not considering the confidentiality, integrity and authenticity of the information; any misuse, destruction, modification or unauthorized access with confidentiality, integrity and authentication information in an organization may affect the privacy or well-being of individuals and society. The objective is to perform the analysis of security models to generate a prototype of model to mitigate information security problems. The deductive method was used to review and analyse the referenced information and identify the ideal security models that allow to improve the security of information in a distributed architecture. Turned out a prototype model merging the characteristics of the BiBa model and the Bell-Lapadula model, creating a new model that offers integrity, confidentiality and access control as an alternative to improve the security of information. It was concluded that it is necessary to have an appropriate security model that conforms to the objectives, operational, tactical and strategic of the organization to mitigate the confidentiality, integrity and authenticity.

It was analysed in a general way and the security problem of the public organizations of Ecuador was determined. The objective is to generate a prototype in a blockchain diagram, based on an algorithm using flowchart techniques to provide robustness against failures, third-party attacks and mitigate information vulnerabilities. The deductive and exploratory research method was used in order to analyse the information available in the medium and scientific articles. Resulted an algorithm developed through flow diagram techniques to improve the processing of information in a public organization in Ecuador from the use of the Blockchain technology and the use of the SHA 256 algorithm. It was concluded that access to the data to a generic public organization of Ecuador will have an alternative to improve the security of the information with the implementation of the blockchain.

The blockchain technology and its platforms applied in different business scenarios and the reasons for adopt a solution was analyzed. The problem is the lack of digital identity model with new technology in a public organization of Ecuador. The objective is to model a blockchain network that applies Hyperledger to establish digital identity in the network and ensure the information integrity in a public organization of Ecuador. It was applied the deductive method and the exploration to examine the information of the cited articles. It turned out Blockchain network prototype in Hyperledger Fabric platform, Sequence diagram for access of users and services, List of Smart Contract functions, Logical model of data, client-server application design. It was concluded that the adoption of Hyperledger for digital identity model provides a highly confidential and scalable network, access certification, contractual procedures, immutable information and audit. It is alternative to guarantee the information security of a process from the beginning to its finalization.
