Which communication method is considered the MOST secure for transmitting highly sensitive intelligence in the field?
Answer: In-person verbal communication in a clean environment
In-person verbal communication in a thoroughly swept, RF-clean environment eliminates electronic interception vectors that exist with any digital method.
A covert radio operator uses the term 'skeds' in the field. What does this refer to?
Answer: Pre-arranged scheduled radio contact windows
Skeds (schedules) are pre-arranged times at which an agent and their handler agree to establish radio contact, reducing random transmission exposure.
What is the operational security (OPSEC) risk of using a personal cell phone for covert communications, even with an encrypted app installed?
Answer: The phone's metadata, location data, and IMSI can still be tracked by adversaries
Even with application-layer encryption, a commercial smartphone continuously emits IMSI, cell tower location data, and behavioral metadata that hostile intelligence can exploit.
In covert communications, what is the function of an 'open code'?
Answer: Innocent-sounding language that conveys a prearranged covert meaning
An open code embeds covert meanings within ordinary conversation or text, so the message appears harmless to unaware third parties.
Which of the following represents the BEST practice for disposing of a one-time pad sheet after use?
Answer: Destroy it immediately and completely
Immediate and complete destruction of used OTP material ensures that an adversary who recovers it cannot reconstruct past communications.
What does the term 'TSCM' stand for in the context of covert communications security?
Answer: Technical Surveillance Countermeasures
TSCM (Technical Surveillance Countermeasures) refers to the process of sweeping a location or device for hidden listening and monitoring equipment.
An agent in the field receives an unexpected communication that matches their protocol but was not on the schedule. The CORRECT response is to:
Answer: Treat it as a potential compromise and follow abort/verification procedures
An off-schedule contact is a red flag that may indicate capture, compromise, or an adversary attempting to exploit the communication channel.
