Information security


In the MSI you will learn the principles and techniques that will give you and your company a competitive edge on security and dependability of critical infrastructures. The program combines safety and dependability on the one hand, and information and infrastructure on the other, mastering a symbiosis between policy/assurance/law and architecture/protocols/technology.
The program provides a solid theoretical basis combined with intensive laboratory work. This way, we aim at creating a new culture: learning how to think and how to do security and dependability.
Besides training of professionals to tackle security technical issues, the program aims at creating a new culture that promotes specific attributes that differentiate it from alternative offers:
Mastering a symbiosis between policy/assurance/law and architecture/protocols/technology.
Taking security (intentional faults) and dependability and fault-tolerance (accidental faults) into account in a seamless way.
Exposure to real-time embedded systems security, expands students’ expertise to fields of smartcards, biometrics, cyber control (e.g. power), critical infrastructure.
Set in an extremely lively research environment, the program offers core courses in security and dependability and a range of electives that provide the opportunity to study some areas in greater depth. The courses are offered by the FCUL Department of Informatics, and students benefit from a dedicated study room and laboratory.
The program has top level international instructors, heavily engaged in high-level research and teaching, and in numerous international research projects in security and dependability.

Introdução à Segurança Informática (Introduction to Computer Security) This course addresses the problem of security in open computational systems, including computers and communication networks, i.e., under a distributed systems perspective. No pre-requisites are demanded on security subjects, but it is expected that students have at least introductory notions of: computational systems and computer networks; operating systems and distributed systems. The valences acquired with the course consist of the knowledge of the foundations, main paradigms and models of security in computer systems and networks from a broad perspective. Students will also be able to understand the main strategies and decisions behind the design of secure computer systems, and will be exposed to the most relevant examples of current systems and technologies. Students will be able to extend this knowledge with subsequent post-graduate studies, or to directly apply it in their professional life, with an advantage in relation to researchers or professionals with a shallow or casual training in security. Throughout the course, students are intended to deal with fundamental security paradigms, like cryptography and access control, or with models for system security such as firewalls, authentication and authorization, key distribution centers, electronic transactions and payment. They will understand the fundamental causes of insecurity— vulnerabilities, originating from design and configuration or operation mistakes; and attacks caused by hackers, leading to intrusions— and the several design strategies and tradeoffs to cope with the former. Students will be exposed at introductory level to concrete technologies like: DES, AES, IDEA, RSA, MD5, SHA, DigiCash, SSL, SSH, Kerberos, PGP, IPTables, Snort. A paper case study will consolidate the course subjects around the design of a secure enterprise system. Sistemas de Software Seguros (Secure Software Systems) Secure Software Systems is a graduate-level course in software security. The objective of the course is to give the students the mental tools necessary to understand the problem of the security of the computer and its software, vis-à-vis the security of the communication or distributed system. The course gives an insight into the security problems in modern software systems, and presents paradigms, models and tools to tackle these problems. Pre-requisites are Introduction to Computer Security, and it is expected that students have at least introductory notions of: computational systems and computer networks; operating systems and distributed systems programming. The first part of the course is an overview of software security, presenting also the basic protection mechanisms (memory protection, access control). In the second part the course presents the main classes of vulnerabilities and how they might be prevented directly: buffer overflows, race conditions, randomness and determinism problems, input validation and the web, passwords and secret data, database security, client-side security. The third part is about techniques and tools to improve the security of software: static analysis, fault/attack injection, assurance/certification, and trusted computing. Tolerância a Faltas Distribuída (Distributed Fault Tolerance) The increasing usage of distributed systems in a number of applications raises two problems: i) the increasing number of components of the system raise concerns about their reliability; ii) the geographical distribution raises interesting possibilities of multi-host replication. The course introduces the concept of distributed fault tolerance, which makes use of several interconnected hosts to replicate software components in a less expensive and more flexible way than with dedicated hardware. The course addresses concepts, methodologies and mechanisms to build reliable networked systems. Tolerância a Intrusões (Intrusion Tolerance) This advanced course addresses the problem of security of computer and communication networks under the tolerance paradigm, or how to prevent security failures under the allowed presence of malicious faults (vulnerabilities, attacks and intrusions). Pre-requisites are Introduction to Computer Security, and it is expected that students have at least introductory notions of: computational systems and computer networks; operating systems and distributed systems. The valences acquired with the course consist of a body of knowledge complementary to the standard prevention approach, which traditionally requires difficult to attain levels of system robustness and intensive and costly human intervention. Figuratively, intrusion tolerance is the road to automatic security, pretty much along the philosophy of classic fault tolerance for accidental faults. Students will be able to master the fundamental concepts, paradigms and mechanisms of intrusion tolerance. They will be exposed to the most relevant examples of such mechanisms, and they will learn to look at several legacy systems and technologies under the intrusion tolerance perspective. Students will also be able to incorporate these notions with classical security notions in a complete design of secure computer systems. Students acquiring the subjects of this course are likely to get a competitive edge in relation to researchers or professionals with a classical training in security, as intrusion tolerance is becoming a mainstream technique in computer systems security. Throughout the course, students are intended to review the fundamental security and dependability concepts and put them in perspective with intrusion tolerance. Classes of fault models adequate to the malicious area— expressing vulnerabilities, attacks and intrusions— will be presented and methods for obtaining security in the light of each class— mechanisms, paradigms, algorithms— will be discussed. Students will study solutions to known hard problems under intrusion tolerance, such as intrusion detection and automated recovery, or denial of service. Segurança Aplicada (Applied Security) This course provides an in-depth study of several topics related to the development and deployment of secure distributed systems. Today, in a global market, organizations and individuals need to be interconnected among them and through the Internet, in order to provide information and services to users, create relations between partners and do business. In this open environment, several kinds of threads exist, perpetrated by a range of individuals. This course will focus on state-of-the-art technologies and solutions for building systems and conducting secure operations in this potentially adverse environment. Pre-requisites are Introduction to Computer Security, and it is expected that students have at least introductory notions of: computational systems and computer networks; operating systems and distributed systems. The course achieves a balanced coverage of: in-depth study of some cryptographic algorithms and mechanisms previously addressed at introductory level; and insight into the implementation of secure distributed systems. The cryptography part addresses basic theory of hash and encryption, studies some popular algorithms, and discusses limitations of these techniques. The system and network security part deals with distributed authentication and key distribution, including a detailed analysis of public key infrastructures, and secure communication on the Internet. In addition, crucial applications such as secure email and electronic payment are also covered. The lecture concepts are complemented through two medium sized hands-on projects. The first one comprises the implementation, optimization and experimental evaluation of a well-known cryptographic algorithm. The second project is about the design and implementation of a secure (real or simulated) distributed application. These projects introduce students to the practical difficulties and trade-offs of developing cryptographic and security techniques and their use to protect a system. Programação em Sistemas Distribuídos (Distributed Systems Programming) The objective of this course is to provide a global perspective of the several architectures and models for the construction of and programming in distributed systems.

Pre-requisites are Embedded Systems and it is expected that students are familiar with the fundamental concepts of computer networks and distributed systems. The course provides the framework for understanding the role of each current and emerging technology under the perspective of building “real” distributed real-time fault-tolerant embedded systems while stimulating a hands-on approach on a relevant set of selected technologies and platforms. In particular, the students will have a comprehensive experimental contact with practical embedded platforms through laboratory experiments and through practical projects. The course will provide a set of valences in the area of embedded and distributed system technologies, which can be equated by the knowledge of practical solutions to attain real-time and dependability properties in distributed control systems that interface “real” devices through sensing and actuating. Students will learn how to build those systems using existing interfacing and networking technologies and how to integrate such technologies with computing and operating system platforms. The students will have a thorough contact with both the specification and the development of such distributed embedded systems.
