In cybersecurity, 'lighter' is not a standard term. However, in the context of 'lighter-than-air' (LTA) technology, it refers to aircraft or devices that remain aloft because they are filled with gases less dense than air, such as helium or hydrogen. Such platforms can be used in cybersecurity and surveillance for persistent monitoring, communication relays, or signal interception. LTAs offer advantages like extended flight duration and broad coverage areas, making them useful for both defensive and offensive cyber operations. Their deployment can enhance situational awareness and facilitate secure data transmission in remote or challenging environments.
