Short Courses of the 19th Brazilian Symposium on Information and Computational Systems Security

Mon, 02 Sep 2019 00:00:00 +0000

The Brazilian Symposium on Information and Computational Systems Security (SBSeg) is the country’s main forum for disseminating research results and relevant activities related to information, data protocols, and computational systems security.

In this edition (2019), 13 short-course proposals were submitted, a significant number that demonstrates the relevance and the community interest in current subjects of the area. Four proposals were selected for publication and presentation, an acceptance rate of 30%. This book comprises the four chapters produced by the authors of the accepted short-course proposals.

Chapter 1 addresses one of the main challenges for information security today: creating and maintaining a reliable digital identity for each user. With the advent of blockchains, new possibilities for assigning and controlling digital identities have emerged and this chapter presents to readers a theoretical discussion and practical activities on creation and managing decentralized identifiers, as well as authentication and revocation of credentials.

Chapter 2 shows how the security area can benefit from the enormous advances made recently in data science and machine learning fields. The goal is to be able to discover security-relevant information that may be hidden in a large amount of non-suspicious data produced by security tools and operating systems. Key concepts in the field will be discussed and several practical examples will be demonstrated using free tools.

Chapter 3 discusses blockchains in depth, as this tool is becoming increasingly used in several areas, including security. Among the various technologies adopted in blockchains, this chapter emphasizes the consensus mechanism, one of the main actors in the performance and security of the chain. The consensus mechanisms most used today require a great deal of computational power to operate satisfactorily and provide an acceptable level of security. In this context, the main types of blockchain and their consensus mechanisms will be presented and discussed, as well as experiments that illustrate in practice different aspects of security in current implementations.

Concluding this book, Chapter 4 focuses on another face of security that has drawn a lot of attention from society: malicious applications that, after infecting a device, seek to hide in a variety of ways in order to escape detection by security mechanisms and forensic techniques, even when they are running. This chapter shows the application of reverse engineering techniques for analyzing malicious applications in the Linux environment, which are exemplified both in kernel and user modes based on their dynamic execution trace and in code debugging techniques.

Memories of the Brazilian Computing Society

Mon, 28 Jul 2014 00:00:00 +0000

Memory is an essential resource for building learning and human survival. It enables the creation of an identity. It is a heritage that makes us unique and also enables improvements in the process of natural evolution of life. To speak of memory is to reflect on what represents us in the world. It permeates not only human life, but also other spaces that build a story.

35 years ago, the history of the Brazilian Computing Society began, a scientific society whose purpose was to promote debate on the issues and challenges of computer science in Brazil. This period was characterized by the need to start producing some technical components internally in Brazil to free us from dependence on importing computers from other countries. We Brazilians needed to develop our tools according to our needs and create our own technology.

The book Memórias da Sociedade Brasileira de Computação makes us understand the heritage acquired over these years and presents us with the place we occupy in Computing in Brazil. This work marks the 35 years of SBC. It was carefully organized by the Director of Professional Relations, the editor Roberto da Silva Bigonha, also a researcher and full professor at the Federal University of Minas Gerais (UFMG) who presents us with data and facts since its foundation as an important scientific society in Brazil.

The publication brings our memory and contextualizes the historical moment, the advances in teaching and scientific research on Computing in the country and the work carried out by SBC for its community through the experience of some of its former presidents over the years.

The book Memórias da Sociedade Brasileira de Computação is an invitation to go back in time. It is through it that we can learn about what has already been achieved by our Society and the challenges to continue valuing and developing teaching and scientific research in Computing in Brazil.

SBC is the result of the contribution and collective work of its members over the years. Upon completing 35 years of history, it presents you, dear reader, with this memory and identity that is also yours. Good reading!
