Global Positioning System (GPS)

Security+ 🏆 • Network Security 🌐 • Threats ⚠️ • Difficulty: premium

Definition

GPS is a satellite-based positioning system that provides location and time information to receivers. In cybersecurity, GPS matters because location data is sensitive, and because many systems rely on GPS for accurate timing and coordination.

Examples

  • A mobile app collects GPS location to provide nearby services, which creates privacy and tracking risk if the data is mishandled.
  • An organization uses GPS-based time sources for synchronized logs, but must consider spoofing and jamming risks for timing-dependent systems.

Discover 🔎

GPS is best known for maps and navigation, but it also quietly supports many digital systems by providing accurate time. Location and time are both powerful pieces of information. Location can reveal where people live, work, and travel. Accurate time is critical for security logs, certificates, authentication systems, and coordination across networks. Because GPS is widely trusted, it is also a target for disruption and deception.

Remember: GPS is both location and time. In security, time synchronization can be just as important as location privacy.
