Os ataques ransomware e a camada de proteção em sistemas governamentais

Levi Alves dos Santos¹

Abstract: Ransomware é um software malicioso utilizado para sequestro e criptografia de dados pessoais, empresariais ou governamentais, seguindo-se a esse roubo/bloqueio um pedido de resgate por meio de criptomoeda, cujo rastreio é impossível. Como questão norteadora está a pergunta: quais são as boas práticas em Gestão de Sistemas em Tecnologia da Informação e como podem colaborar para mitigar os ataques ransomware? O objetivo deste artigo consiste em apresentar múltiplos casos de ataques ransomware aos sistemas eletrô… Show more

In the midst of technological advances and recurrent cyber attacks that affect the data systems of different organizations, the search for automation and acceleration in a structured way are the triggers for the beginning of the modernization of processes in Information Technology (IT). The SAP system, of German origin, is considered a strong system and has been used by medium and large companies, national and multinational. It has specific characteristics, such as automation and agility for internal processes, use of robots and Artificial Intelligence (AI), all of which is stored in the cloud. A SAP system promotes improvements in customer service, inventory control and purchasing needs, avoids or minimizes product losses, streamlining sales processes, asset management and allowing greater ease in consolidating information, including for administrative, accounting and financial sectors. In this context, SAP S/4HANA, or “SAP Business Suite 4 SAP HANA”, is the newest generation of the set of business solutions; is the most advanced version, created to simplify all transactions between organizations, as well as in their internal processes. As a research methodology, bibliographical research was adopted to answer the following question: how to secure data, optimize internal processes and ensure greater agility and savings for organizations? The objective of the article is to present the concepts inherent to each of the mentioned aspects, and to demonstrate the effectiveness of using the SAP S/4HANA system.

Since the emergence of the internet, the vertiginous growth in the use of electronic media has grown in the same proportion as cyber crimes, applied in an increasingly sophisticated way. In addition to these two factors that impact the use of the internet, the speed with which the resources and tools inherent in the area of Information and Communication Technology (ICTs) evolve, which enhance the need to continuously develop and improve the means for the protection of sensitive data of people and public and private organizations. In this perspective, Cloud Computing emerges, which allows the storage of data, networks and applications, and other resources through integrated environments through the internet, from collective providers, as opposed to the on-premise system, which is based on the custody and access through local servers, including mainframes, which are still maintained in most large organizations, such as the banking system, for example. Added to Cloud Computing are Zero Trust practices, whose main innovation is the adoption of several layers of access verification. This article was prepared using bibliographical research as a methodology. The question that arises on the subject is: how does Zero Trust provide greater security to network users? The objective is to demonstrate the advantages of security provided by Zero Trust, combined with Cloud Computing. In view of the analyzed literature, it was possible to conclude the existence of two main aspects brought by Zero Trust: internet user access only from 7 layers of verification, and the mitigation of vulnerabilities, including the idea of responsible browsing by different users.

Desde o surgimento da internet, o crescimento vertiginoso do uso dos meios eletrônicos cresce na mesma proporção em que ocorrem os crimes cibernéticos, aplicados de forma cada vez mais sofisticada. Além desses dois fatores que impactam o uso da internet, destaca-se a velocidade com que evoluem os recursos e ferramentas inerentes à área de Tecnologia da Informação e Comunicação (TICs), que potencializam a necessidade de serem desenvolvidos e aperfeiçoados, continuamente, os meios de proteção de dados sensíveis de pessoas e organizações públicas e privadas. Nesta perspectiva, surge a Cloud Computing, que permite o armazenamento de dados, redes e aplicações, e demais recursos por meio de ambientes integrados através da internet, a partir de provedores coletivos, em contraponto ao sistema on-premise, que se baseia na guarda e acesso por meio de servidores locais, inclusive mainframes, que ainda são mantidos em boa parte das organizações de grande porte, como o sistema bancário, por exemplo. Ao Cloud Computing somem-se as práticas do Zero Trust, cuja principal inovação consiste na adoção de várias camadas de verificação de acesso. Este artigo foi elaborado adotando como metodologia a pesquisa bibliográfica. A pergunta que surge sobre o tema é: de que forma a Zero Trust confere maior segurança aos usuários das redes? Como objetivo pretende-se demonstrar as vantagens da segurança proporcionadas pela Zero Trust, aliadas à Cloud Computing. Diante da literatura analisada, foi possível concluir a existência de dois aspectos principais trazidos pela Zero Trust: o acesso do internauta somente a partir de 7 camadas de verificação, e a mitigação das vulnerabilidades, entre elas a ideia sobre navegação responsável pelos diferentes usuários.
