NIST SP 800-53 Rev 5 SC-8: Transmission confidentiality and integrity
Requires the confidentiality or integrity, as the organization determines, of transmitted information to be protected, so that data in transit cannot be read or altered by parties along the path.
What else in your programme already covers this
This control maps to 122 controls across 35 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
3.4.2 Technical controls prevent unauthorized PAN copy
4.2.1 Strong cryptography and security protocols are implemented as follows to safeguard PAN during transmission over open, public networks: • Only trusted keys and certificates are accepted. • Certificates used to safeguard PAN during transmission
4.2.1.1 Inventory of trusted keys and certificates
4.2.1.2 Wireless networks transmitting PAN use strong cryptography
4.2.2 PAN is secured with strong cryptography whenever it is sent via end-user messaging technologies
8.3.2 Strong cryptography is used to render all authentication factors unreadable during transmission and storage on all system components
You are reading one control. How much of NIST SP 800-53 Rev 5 have you already done?
NIST SP 800-53 Rev 5 SC-8 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of NIST SP 800-53 Rev 5 your existing evidence covers. Hold ISO 27001:2022 and 163 of 300 NIST SP 800-53 Rev 5 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 342 were rejected on the ISO 27001:2022 pair alone.
