Subject fundamentals
The course is taught in English.

This is a compulsory course for the Laurea Magistrale in Computer Engineering, given at the I semester of the II year. This course deals with security issues in modern networked computer systems, paying special attention to data security and protection of computer networks and networked computer applications, in a closed (Intranet) or open (Internet) environment. The course aims to teach the skills needed to perform both the analysis and design of the security features of a networked computer system.
Expected learning outcomes
- Knowledge of the main categories of attack against networked computer systems
- Knowledge and critical evaluation of the main methodologies (encrypyion and digest) and technologies (PKI, firewall, VPN, TLS, S/MIME, e-documents) for computer and information security
- Knowledge and critical evaluation of the security architectures for authentication and access control and ability to tailor them to the protection of networked computer systems
- Ability to analyse the risks of a network application and design a solution for its protection
Prerequisites / Assumed knowledge
Ethernet local networks. Wireless networks. TCP/IP networks and applications. High-level programming (in C, C++ or Java). Operating Systems.
- (1 CFU) Computer systems (in)security: problems and attacks (sniffing, spoofing, DOS, ').
- (1 CFU) Basic protection techniques: steganography, cryptography, digest, X.509 certificates, certification authorities (CA) and public-key infrastructures (PKI).
- (1 CFU) Authentication techniques (password, challenges, Kerberos) and related hardware devices (token and smart-card).
- (1 CFU) Network security: the IPsec standard to protect IP networks; security of the network configuration and management protocols; firewall and IDS to create protected subnets; virtual private networks (VPN); security of wireless networks.
- (1 CFU) Application security: e-mail protection (PGP, S/MIME), web security (SSL, TLS) and remote access protection (SSH, SSL, TLS), securing web applications.
- (1 CFU) Secure document workflow and e-commerce; national and international legislation about e documents; digital signature and e documents; the SET protocol and other e-payment systems.
Delivery modes
The laboratory includes the development and analysis of several security solutions. There will be 6-7 different labs, possibly repeated.
The classroom exercises will analyse some security solutiona, including those developed in the labs.
Texts, readings, handouts and other learning resources
The reference text, covering most but all the topics, is:
- W. Stallings, 'Cryptography and Network Security ' principles and practice', Prentice-Hall (5th ed.)
Additionally the lessons' handouts and laboratory manuals are available from a web site.
Assessment and grading criteria
Written exam (2 hours) about the analysis and design of security solutions. Alternatively, the student can develop an individual homework about one of the course's topics.

The course syllabus and the exam test are coincident with those of the same course given in Italian language (Sicurezza dei Sistemi Informatici).
