Access Control AC Your Deep Dive into NIST 800 171r3 CUI Security
Welcome to a focused deep dive into the Access Control (AC) family of security requirements—one of the cornerstones of NIST Special Publication 800-171r3: Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations.
This session is designed to unravel the critical aspects of controlling access to sensitive data and ensuring the confidentiality of Controlled Unclassified Information (CUI) in diverse environments.
🔎 What is NIST 800-171r3 about?
NIST SP 800-171r3 provides federal agencies with recommended security requirements for protecting the confidentiality of CUI when it resides in nonfederal systems and organizations.
CUI includes information that requires safeguarding or dissemination controls by law, regulation, or government-wide policy, excluding classified information. These security requirements are derived from the robust controls found in NIST SP 800-53.
🧱 Understanding the Access Control (AC) Family:
The Access Control family, identified as AC, is one of 17 security requirement families crucial to safeguarding CUI. These apply to system components that process, store, transmit, or protect CUI. Even if not explicitly stated, all requirements directly affect CUI protection.
📘 Key Requirements Covered in This Deep Dive:
• 03.01.01 – Account Management
Defines managing system accounts, authorized users, access authorizations, account monitoring, and criteria for account disabling.
• 03.01.02 – Access Enforcement
Covers approved authorizations for logical access, including remote and external network access.
• 03.01.03 – Information Flow Enforcement
Controls the flow of CUI within and between connected systems (e.g., preventing clear-text internet transmission).
• 03.01.04 – Separation of Duties
Reduces insider threat by identifying duties that require separation and assigning proper access authorizations.
• 03.01.05 – Least Privilege
Grants users only the access necessary for their tasks, with periodic review.
• 03.01.06 – Privileged Accounts
Restricts privileged access to specific roles and promotes use of non-privileged accounts for general activities.
• 03.01.07 – Privileged Functions
Prevents unprivileged users from executing privileged tasks and requires logging all privileged functions.
• 03.01.08 – Unsuccessful Logon Attempts
Limits the number of invalid login attempts within a defined timeframe.
• 03.01.09 – System Use Notification
Requires privacy and security notices before system access.
• 03.01.10 – Device Lock
Mandates locking devices after inactivity and hiding sensitive data on screens.
• 03.01.11 – Session Termination
Terminates sessions automatically after predefined conditions are met.
• 03.01.12 – Remote Access
Defines and enforces usage and configuration of remote access via managed access control points.
Incorporates 03.01.13, 03.01.14, and 03.01.15.
• 03.01.16 – Wireless Access
Controls configuration and authorization of wireless access.
Incorporates 03.01.17.
• 03.01.18 – Mobile Device Access Control
Applies encryption and specific control for mobile devices containing CUI.
Incorporates 03.01.19.
• 03.01.20 – Use of External Systems
Restricts use of unauthorized external systems and limits storage devices on those systems.
Incorporates 03.01.21.
• 03.01.22 – Publicly Accessible Content
Trains personnel to prevent CUI from being posted publicly and reviews content periodically.
🎯 Who Is This For?
This deep dive is essential for:
✔️ Federal agencies
✔️ Defense contractors
✔️ Nonfederal organizations
✔️ System developers, assessors, and compliance professionals
It provides clear, actionable insights into how to meet CUI protection mandates through robust access control mechanisms.
