Side-Channel Awareness
Leakage surface awareness
Metadata, acoustic, optical, thermal, electromagnetic and behavioral signals can leak context.
Defensive use
Educate teams about meeting hygiene, screen reflections, metadata and sensitive-room controls.
Potential indicators
- - Visible screens
- - EXIF data
- - Calendar metadata
- - Predictable routines
Mitigation direction
- - Screen privacy
- - Metadata stripping
- - Room controls
- - Communication hygiene
Educational awareness only; no attack construction or interception instructions.
Metadata
File EXIF, calendar invites, subject lines, link previews and headers can expose context without content.
Defensive awareness only. No collection or attack instructions.
Acoustic
Sounds may disclose activity patterns. Use meeting hygiene and sensitive-room awareness.
Defensive awareness only. No collection or attack instructions.
Optical
Reflections, screen shares and photos can leak screens, locations or relationships.
Defensive awareness only. No collection or attack instructions.
Thermal
Thermal patterns are a specialist topic; OBSERVA covers only high-level awareness.
Defensive awareness only. No collection or attack instructions.
Electromagnetic
TEMPEST-style concerns are high-level governance topics, not implementation guidance.
Defensive awareness only. No collection or attack instructions.
Behavioral
Routines, timing and repeated patterns can reveal sensitive operations.
Defensive awareness only. No collection or attack instructions.
