Security in Computer Systems 2017/2018

  • 6 ECTS
  • Taught in Portuguese
  • Continuous Assessment


Upon completion of this course the successful students should be able to:
- Explain the fundamental concepts of security systems;
- Define a security policy for a typical system;
- Analyze and point out the appropriate mechanisms used in the implementation and monitoring of a typical security system;
- Analyze a data network and identify the associated main protection levels;
- Analyze, program and manipulate some security devices or techniques in real situations

Recommended Prerequisites

Basic knowledge of computer networks and operating systems

Demonstration of the syllabus coherence with the curricular unit's objectives

In order to students could specify a security policy and determine the appropriate mechanisms to be used in the implementation and control are taught subjects such as protection of communication channels, Security in computer networks, malicious software, VPN and firewalls.

In order to analyse, program and operate some devices or security techniques in real situations, in addition to the concepts learned in lectures students in practical classes, performing work with applications used in the safety analysis of computer systems.

Demonstration of the teaching methodologies coherence with the curricular unit's objectives

The teaching-learning methodologies are aimed at developing the learning skills of students in order to allow them to comply with each of the learning goals. So, we present below the main interconnections between the methodologies used and presented objectives.
1. Expositive to present the theoretical concepts of reference;
2. Practices with students involvement, mainly with analysis and problem solving;
3. Self-study related to the autonomous work of the student.
