Signaalipuolustus

Signaalipuolustus is a military concept referring to the measures and capabilities designed to protect and sustain the signals, communications, and information systems that support military operations. The term covers the integrity, availability, and confidentiality of communications networks and data, as well as the management of the electromagnetic spectrum used for defense purposes.

Core elements include secure voice and data transmission, encryption and key management, cyber defense and network security, and protection against electronic warfare such as jamming and spoofing. It also encompasses physical security of communications facilities, redundancy and disaster recovery, incident response, and ongoing training and doctrine for personnel.

In the Finnish defense context, signaalipuolustus aligns with broader information and cyber defense efforts within the defense forces and is coordinated with other branches and civil authorities to ensure resilient command and control in peacetime and wartime conditions.
