Analysis for the evaluation and security management of a database in a public organization to mitigate cyber attacks

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.
