SC-30(5)—Concealment Of System Components
>Control Description
Employ the following techniques to hide or conceal ⚙organization-defined system components: ⚙organization-defined techniques.
>Cross-Framework Mappings
>Supplemental Guidance
By hiding, disguising, or concealing critical system components, organizations may be able to decrease the probability that adversaries target and successfully compromise those assets. Potential means to hide, disguise, or conceal system components include the configuration of routers or the use of encryption or virtualization techniques.
>Assessment Interview Topics
Questions assessors commonly ask
Process & Governance:
- •What policies govern the implementation of concealment of system components?
- •How are system and communications protection requirements defined and maintained?
- •Who is responsible for configuring and maintaining the security controls specified in SC-30(5)?
- •What is your cryptographic key management policy?
Technical Implementation:
- •How is concealment of system components technically implemented in your environment?
- •What systems, tools, or configurations enforce this protection requirement?
- •How do you ensure that concealment of system components remains effective as the system evolves?
- •What encryption mechanisms and algorithms are used to protect data?
Evidence & Documentation:
- •What documentation demonstrates the implementation of SC-30(5)?
- •Can you provide configuration evidence or system diagrams showing this protection control?
- •What logs or monitoring data verify that this control is functioning correctly?
- •Can you demonstrate that FIPS 140-2 validated cryptography is used?
