Course description

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.

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 the high-level design of the security features of IT components and systems.
