Credits 6

Learning outcomes

The main objective of the course is to introduce the problem of security issues due to intentional and unintentional electromagnetic signals as well as countermeasure methods.
Specifically, students will acquire the following competences: i. how an information and communication system is vulnerable to radiated and conducted electromagnetic fields; ii. how to design electromagnetic shielding and secure rooms for data protection from electromagnetic threats; iii. which NATO standards and procedures are currently in use for limiting the information leakage through radiated and conducted electromagnetic signals.
Main topics
- Electromagnetic threats - Vulnerability of information systems to electromagnetic threats
- Undesired emissions from non-intentional sources and E.M. signals interception: E.M. propagation fundamentals
- Spectrum sensing and monitoring - Radiogonometry systems - Signal demodulations - Omnidirectional and directional antennas
- E.M. Shielding and secure rooms: effect of materials, effect of apertures and cable connections. Coupling mechanisms of e.m. signals. Zoning of infrastructures.
- Active security and intentional interferences: Radio Jamming - Friendly jamming for secure wireless communications
- Standards and measurement procedures: COMSEC and TEMPEST (Transient Electromagnetic Pulse Emanation Standard) - National and international (NATO) standards - TEMPEST equipment and devices
