Normally COMSEC users are issued no more than one months supply of material; however, is a user needs more for an effective mission, the COMSEC manager issues sufficient COMSEC aids to meet the need, but no more than...?
Definition
120 Days worth.
Term
What is bulk filtering?
Definition
The practice of using filters at the first service disconnect.
Term
What is low-level signaling?
Definition
Equipment that uses low voltage and current levels to reduce compromising emanations.
Term
What is RED equipment?
Definition
Equipment that processes classified information before encryption and after decryption.
Term
Is most "commercially available off the shelf" equipment TEMPEST approved?
Definition
No, most of this equipment is nto designed with TEMPEST protection in mind.
Term
What is the objective of RED/BLACK signal distribution?
Definition
To provide an organized scheme to transfer signals from the source(transmitter) to the sink (reciever) in such a manner that RED/BLACK integrity is maintained, interferenced is not intercepted from other sources, and interference is not created.
Term
Typically what type of output (line side) signals are generated by modems, and what is the frequency range of these signals?
Definition
Analog signals in the VF range of 300 to 4000 Hz.
Term
How can the possibility of EMI be minimized when using digital signalling?
Definition
Using low-level voltage, properly terminating all cable pairs, and ensuring sheilds are properly closed and grounded.
Term
Why are patch panels installed in facilities having a RED and BLACK distribution sytem?
Definition
Allows equipment and signal paths to be interchanged in the event of a failure.
Term
Where are surge, transient, EMI/RFI, and EMP/HEMP protective measures applied to signal lines entering and leaving the facility?
Definition
At the facilty entry plates.
Term
Why are signal distribution schemes used in RED and BLACK enviroments?
Definition
To ensure the proper segregation and integrity of signals.
Term
When is filtering of signals not nessecary in RED and BLACK enviroments?
Definition
When TEMPEST approved euipment is being used, the lines are encrypted, proper RED/BLACK separation is maintained, and proper installation procedures have been used.
Term
In regard to emission security, what is the basic purpose of filter, isolators, and shields?
Definition
Attenuation of undesirable signals that attempt to pass through these devices.
Term
How does filtering help reduce compromising emanations?
Definition
By shunting the interfering or compromising energy to a return path and reflecting it back to the source.
Term
Why should an external barrier of a facilty use filters (Preceded by surge arrestors) in preference to isolators?
Definition
To prevent arcing when a large incoming voltage transient encounters an open circuit.
Term
What is ground in relation to signals?
Definition
Ground is merely an agreed upon potential to which signal voltages may be referenced.
Term
What type fo field does ferrous and nonferrous shielding material attenuate?
Definition
Ferrous are used for magnetic fields, whereas nonferrous materials are used for electrostatic fields.
Term
When you use non-TEMPEST equipment and/or high-level signalling, what configuration of the RED and BLACK power distribution may be required?
Definition
Seperated RED and BLACK power distribution.
Term
If possible, where should prime power source be located when emmission security is a concern?
Definition
Totally Contained within the CS.
Term
What two types of powers systems are used in facilties?
Definition
Technical and non-technical
Term
What is the purpose of a non-technical power system?
Definition
To provide power to air-conditioning, lighting, and houskeeping functions.
Term
What is the purpose of a technical power system?
Definition
Provide power to the equipment associated with the mission. This includes any lighting and enviromental equipment essential to system operation.
Term
Why should power line filters be custom designed for individual equipment?
Definition
This allows the filter to be designed specifically to the parameters and characteristics of the equipment.
Term
When is it permissable to filter the power of a BLACK prcessor?
Definition
When the entire facility has been provided with filtered power.
Term
Why should you install disconnect devices, noninductive ringers, and speech supression devices on a telephone that serves an LEA?
Definition
To prevent the telephone from becoming a microphone and compromising the the LEA
Term
Why is line separation immportant in minimizing emanations?
Definition
The electromagnetic field surrounding a conductor reduces with distance
Term
Whom should you consult BEFORE moving or installing any classified processor or moving or installing other devices near classified processors?
Definition
Cognizant TEMPEST authority
Term
Which areas are not included in a technical evaluation?
Definition
Job proficiency and knowledge of the maitenance technician.
Term
The evaluation that gives the commander a factual, objective assesment of a section's ability to meet its mission is a...?
Definition
Managerial
Term
What two discrepancy catagories are documented on a technical evaluation report?
Definition
Major or Minor
Term
A major discrepancy is any dificiency that...?
Definition
creates an unsafe condition or may cause a security violation.
Term
What are the organization's responsibilities in the communication and information system process?
Definition
Identifies communications and information systems requirements and allocates resources.
Term
Who approves the technical solution?
Definition
Requester/User
Term
Commercial equipment manuals are...?
Definition
provided by the vendor and are similar to TOs.
Term
