Schedule Your CMMC AssessmentHow It Works
Comprehensive Assessment & Gap Analysis
We begin with a thorough assessment of your existing time synchronization infrastructure, identifying current practices, authoritative time sources, and any discrepancies across your global network against CMMC Level 2 and NIST SP 800-171 3.3.7 requirements. This includes evaluating NTP/PTP configurations, log integrity, and system clock accuracy.
Strategic Design & Policy Development
Based on our findings, we develop a tailored time synchronization strategy. This includes selecting appropriate authoritative time sources (e.g., NIST network time servers, GPS-disciplined clocks), designing secure synchronization protocols, and crafting robust policies and procedures to ensure consistent implementation and maintenance across all CUI-handling systems, wherever they are located.
Implementation Support & Validation
Our experts guide your team through the secure implementation of the designed solution, configuring Network Time Protocol (NTP) or Precision Time Protocol (PTP) clients and servers. We then rigorously validate the accuracy and resilience of your synchronization mechanisms, ensuring all systems consistently report time with the required precision and integrity for audit readiness.
Continuous Monitoring & Audit Preparedness
We assist in establishing processes for ongoing monitoring of time synchronization health and deviations. This ensures continuous compliance and provides irrefutable evidence for CMMC Level 2 audits, demonstrating that your organization maintains an authoritative and synchronized time source for all CUI-related activities and event logging globally.

- Controlled Unclassified Information (CUI)
- Information that the government creates or possesses, or that an entity creates or possesses for or on behalf of the government, that a law, regulation, or government-wide policy requires or permits to have safeguarding or disseminating controls. It is not classified information.
- NIST SP 800-171
- NIST Special Publication 800-171, 'Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations,' outlines the security requirements for protecting CUI when it resides in nonfederal information systems and organizations. It is the foundation for CMMC Level 2.
- Network Time Protocol (NTP)
- A networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. NTP is widely used to synchronize the time of computer systems with an authoritative time source.

Frequently Asked Questions
What is CMMC Level 2 control AU.L2-3.3.7 (Time Synchronization)?
AU.L2-3.3.7, derived from NIST SP 800-171 control 3.3.7, mandates that organizations must synchronize system clocks with an authoritative time source. This control is fundamental for maintaining the integrity and accuracy of system logs, which are crucial for forensic investigations, incident response, and overall cybersecurity posture. For CMMC Level 2, demonstrating this capability is essential for any system processing, storing, or transmitting Controlled Unclassified Information (CUI).
Why is time synchronization so critical for CMMC compliance and CUI protection?
Accurate time synchronization is paramount for several reasons. Firstly, it ensures that all events recorded in audit logs across various systems have consistent and reliable timestamps. This consistency is vital for correlating events during a security incident, reconstructing attack sequences, and understanding the scope of a breach. Without it, logs can be misleading or useless, hindering detection and response efforts. Secondly, CUI protection relies heavily on the ability to audit access and activity; reliable timestamps provide irrefutable evidence of who accessed what and when, satisfying crucial CMMC requirements for accountability and non-repudiation.
How does Jun Cyber help organizations achieve AU.L2-3.3.7 compliance globally?
Jun Cyber offers end-to-end consulting for AU.L2-3.3.7. We start by assessing your current time synchronization setup, identifying authoritative sources, and evaluating clock accuracy across all your systems, including those in different global regions. We then design a secure, robust synchronization strategy leveraging protocols like NTP or PTP, ensuring it aligns with NIST guidelines. Our team provides implementation support, develops comprehensive policies and procedures, and helps establish monitoring mechanisms to maintain continuous compliance. Our global perspective ensures solutions are practical for distributed environments.
What are common challenges in implementing AU.L2-3.3.7 for large or international organizations?
Large or international organizations often face several challenges. These include managing systems across multiple time zones, ensuring all diverse devices (servers, workstations, network devices, specialized equipment) are synchronized to the same authoritative source, and protecting the time synchronization infrastructure itself from tampering. Network latency, firewall configurations, and the sheer scale of devices can complicate accurate and consistent synchronization. Additionally, documenting and proving continuous synchronization across a vast infrastructure can be a significant administrative burden during audits.
Does AU.L2-3.3.7 apply to cloud environments and Software-as-a-Service (SaaS) solutions?
Yes, absolutely. The requirement to synchronize system clocks with an authoritative time source extends to systems hosted in cloud environments (IaaS, PaaS) and, where applicable, to how SaaS solutions handle timestamps related to CUI processing. While cloud providers often manage underlying infrastructure time synchronization, your organization remains responsible for ensuring that the clocks of your cloud-based virtual machines, containers, and applications are correctly synchronized. For SaaS, you must verify that the service provider's time synchronization practices meet CMMC L2 standards, especially concerning audit logs and data integrity for CUI.
What documentation is required to demonstrate compliance with AU.L2-3.3.7?
To demonstrate compliance with AU.L2-3.3.7, organizations typically need to provide several pieces of evidence. This includes documented policies and procedures outlining how system clocks are synchronized, details on the identified authoritative time source(s) (e.g., NIST, internal Stratum 1/2 servers), configuration files for NTP or PTP clients/servers, and records of system clock accuracy checks. Furthermore, audit logs that clearly show consistent and accurate timestamps across various system components are critical evidence, proving that the synchronization process is actively and effectively implemented.
