ICD 705 outlines the construction requirements for walls, floors, ceilings, and windows in secure facilities to protect classified information. These requirements ensure that all surfaces provide a barrier against unauthorized access, with specific standards for materials, thickness, and reinforcement to prevent physical penetration or eavesdropping. Additionally, construction must comply with sound attenuation and RF shielding criteria to mitigate the risk of espionage.

TEMPEST requirements under ICD 705 focus on controlling electromagnetic emanations to prevent the unintentional transmission of classified information from secure facilities. These requirements mandate that facilities be designed and constructed with shielding measures, such as specialized materials and construction techniques, to limit or eliminate the risk of interception of electronic signals. Compliance with TEMPEST standards are critical for safeguarding against espionage through electromagnetic surveillance.

ICD 705 specifies sound attenuation requirements to prevent the leakage of classified conversations from secure areas. These requirements involve using soundproofing materials and construction techniques that meet specific Sound Transmission Class (STC) ratings. The goal is to ensure that walls, doors, and other barriers effectively block or reduce sound transmission, protecting sensitive discussions from being overheard outside the secure space.

ICD 705 mandates the use of Intrusion Detection Systems (IDS) to safeguard secure facilities from unauthorized access. These systems must be capable of detecting and alerting security personnel to any breaches or attempted intrusions through doors, windows, walls, or other entry points. IDS components, including sensors and alarms, must be strategically placed and regularly tested to ensure continuous protection of classified information.
