Does an unencrypted RED wire line or fiber-optic line pass through an area of lesser classification?

• If the area is all cleared and controlled 24/7 to the same level, no PDS is required.
• If the information is encrypted, no PDS is required. (Compare costs. Encryption devices may be more cost effective than a PDS.)

2. PDS should not be concealed.
3. Employees should be aware PDS exists.
