Introduction:
The U.S. Department of War’s 60‑day pause on CMMC Phase II, announced on July 13, 2026, has left many Defense Industrial Base (DIB) contractors uncertain about their compliance roadmap. Yet the underlying mandate remains unchanged: Phase I self‑assessment requirements and DFARS 252.204‑7012 obligations are still fully in force. Against this backdrop, Kiteworks – a secure content communications platform with FedRAMP Moderate Authorization and FedRAMP High In Process status – has partnered with A‑LIGN, a leading CMMC Third Party Assessor Organization (C3PAO) that has conducted nearly 100 CMMC Level 2 assessments. Their collaboration offers DIB organizations a clear, dual‑pronged path: deploy the Kiteworks Control Plane to address the majority of CMMC Level 2 controls out of the box, then engage A‑LIGN for independent validation.
Learning Objectives:
- Understand the technical requirements of CMMC Level 2 and how they map to NIST SP 800‑171 controls.
- Learn how to deploy and configure the Kiteworks platform to satisfy encryption, access management, and CUI isolation controls.
- Master the evidence collection and documentation process required for a successful C3PAO assessment.
- Gain practical Linux/Windows commands and scripts for hardening systems, auditing access logs, and validating FIPS 140‑3 compliance.
- Develop a step‑by‑step readiness plan that bridges the gap between implementation and independent assessment.
You Should Know:
- Decoding CMMC Level 2 – The NIST SP 800‑171 Foundation
CMMC Level 2 maps directly to all 110 controls of NIST SP 800‑171 Revision 2, organized across 14 control families, with 320 assessment objectives drawn from NIST SP 800‑171A. This is not a “checklist” compliance regime; it demands demonstrable, auditable evidence that every control is effectively implemented. For DIB contractors handling Controlled Unclassified Information (CUI), a C3PAO assessment is mandatory for most contracts.
Step‑by‑step guide to understanding your control baseline:
- Map your environment to the 14 control families: Access Control (AC), Awareness and Training (AT), Audit and Accountability (AU), Configuration Management (CM), Identification and Authentication (IA), Incident Response (IR), Maintenance (MA), Media Protection (MP), Personnel Security (PS), Physical Protection (PE), Risk Assessment (RA), Security Assessment (CA), System and Communications Protection (SC), and System and Information Integrity (SI).
- Conduct a gap analysis against the 110 controls. Kiteworks addresses nearly 90% of CMMC Level 2 requirements out of the box, making it a strategic starting point.
- Prioritize controls that frequently become evidence gaps: CUI isolation, encryption key management, and access logging are among the most common reasons for remediation cycles.
Useful Linux command to audit file permissions on systems handling CUI:
Audit world-writable files and directories that may expose CUI find / -type f -perm -0002 -ls 2>/dev/null | grep -v "/proc/" > world_writable_files.txt Check for SUID/SGID binaries that could lead to privilege escalation find / -perm /6000 -type f 2>/dev/null | xargs ls -la > suid_sgid_binaries.txt Verify that auditd is running and collecting logs systemctl status auditd auditctl -l
Windows PowerShell command to audit file access permissions:
Get all files with "CUI" in the name and check their ACLs
Get-ChildItem -Path C:\ -Recurse -ErrorAction SilentlyContinue | Where-Object { $<em>.Name -match "CUI" } | ForEach-Object { Get-Acl $</em>.FullName }
- Deploying the Kiteworks Control Plane – Hardened Single‑Tenant Virtual Appliance
Kiteworks deploys as a FIPS 140‑3 validated, hardened single‑tenant virtual appliance. This architecture eliminates the CUI isolation failures that plague multi‑tenant environments, where data from different customers commingles on shared infrastructure. The platform has undergone nine consecutive years of annual 3PAO audits, validating 325 NIST 800‑53 controls since 2017.
Step‑by‑step guide to deploying and configuring the Kiteworks appliance:
- Provision the virtual appliance in your chosen cloud (AWS, Azure, or on‑premises VMware) with the recommended CPU, memory, and storage specifications.
- Configure network segmentation: Place the appliance in a dedicated security zone with strict inbound/outbound firewall rules. Only allow necessary ports (HTTPS 443 for web interface, SFTP 22 for secure file transfers, etc.).
- Enable Hold Your Own Key (HYOK) encryption: This gives your organization full ownership of cryptographic keys, reducing audit scope and third‑party exposure.
- Set up data governance policies: Define rules for secure file sharing, encrypted email, managed file transfer, and secure web forms – all consolidated into a single platform.
- Integrate with your identity provider (IdP) for single sign‑on (SSO) and multi‑factor authentication (MFA), satisfying IA‑2 (Identification and Authentication) controls.
Verification command to confirm FIPS 140‑3 mode on a Linux system:
Check if FIPS mode is enabled on RHEL/CentOS cat /proc/sys/crypto/fips_enabled For OpenSSL, verify FIPS-compliant cipher suites openssl ciphers -v 'ALL:eNULL' | grep -i fips
Windows command to check FIPS compliance:
Check FIPS policy setting in Windows Registry Get-ItemProperty -Path "HKLM\System\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy" -1ame "Enabled"
- Closing Evidence Gaps – What C3PAOs Actually Look For
A‑LIGN’s assessors evaluate the complete scope of CMMC Level 2, including governance, personnel, physical security, and organizational controls. The most common reason DIB organizations fail assessments is not a lack of controls, but insufficient or poorly organized evidence. A‑LIGN’s role in this partnership is strictly limited to independent assessment – they do not consult, remediate, or advise on control implementation, preserving their objectivity as a C3PAO.
Step‑by‑step guide to evidence preparation:
- Develop a System Security Plan (SSP): This is the core document describing how your organization protects CUI. It must articulate, for each of the 110 controls, how you implement it, who is responsible, and what evidence supports it.
- Collect and organize evidence artifacts: For each control, gather configuration files, audit logs, policy documents, training records, and screen captures. Use a centralized repository (e.g., the Kiteworks platform itself) to store and share evidence securely.
- Run a readiness self‑assessment using the CMMC assessment objectives. Map each objective to a specific piece of evidence. If you cannot produce evidence, you have a gap.
- Engage A‑LIGN for a pre‑assessment readiness review (separate from the formal assessment) to identify deficiencies before the official C3PAO audit.
- Practice the assessment process with internal or third‑party mock audits.
Linux command to collect system configuration evidence:
Collect system information for SSP documentation uname -a > system_info.txt cat /etc/os-release >> system_info.txt cat /etc/audit/audit.rules > audit_rules.txt Backup current iptables/nftables rules as evidence of configuration management iptables-save > iptables_rules_backup.txt nft list ruleset > nftables_rules_backup.txt
Windows command to collect security policy evidence:
Export local security policy for evidence secedit /export /cfg secpol_export.inf List all installed updates for patch management evidence Get-HotFix | Export-Csv -Path hotfixes.csv -1oTypeInformation Export audit policy configuration auditpol /get /category: > audit_policy.txt
- CUI Isolation and Access Management – Avoiding the Most Common Pitfall
CUI isolation failures are among the most frequent reasons DIB organizations require remediation cycles before earning CMMC certification. The Kiteworks single‑tenant appliance ensures that CUI is physically and logically separated from other data, but you must also enforce strict access controls at the operating system and network levels.
Step‑by‑step guide to CUI isolation:
- Designate a CUI enclave: Create a separate network segment (VLAN or VNet) exclusively for systems that process, store, or transmit CUI.
- Implement network access controls: Use firewalls and network ACLs to restrict traffic between the CUI enclave and non‑CUI networks. Default deny – allow only explicitly required communications.
- Enforce role‑based access control (RBAC): Only users with a legitimate need‑to‑know should have access to CUI. Implement least privilege principles.
- Enable comprehensive logging: All access to CUI must be logged, including who accessed what, when, and from where. Retain logs for at least one year (or as required by your contract).
- Regularly review access rights: Conduct quarterly reviews of user permissions and remove inactive or unnecessary accounts.
Linux command to set up a basic CUI directory with strict permissions:
Create a dedicated CUI directory with strict permissions mkdir /cui_data chown root:cui_admin /cui_data chmod 750 /cui_data Set default ACLs to ensure new files inherit correct permissions setfacl -d -m g:cui_admin:rwx /cui_data setfacl -d -m o: /cui_data
Windows PowerShell script to enforce CUI folder permissions:
Create CUI folder and set strict NTFS permissions $cuiFolder = "C:\CUI_Data" New-Item -Path $cuiFolder -ItemType Directory icacls $cuiFolder /inheritance:r icacls $cuiFolder /grant "BUILTIN\Administrators:(OI)(CI)F" icacls $cuiFolder /grant "DOMAIN\CUI_Admins:(OI)(CI)RW" icacls $cuiFolder /deny "Everyone:(OI)(CI)(RX,W)"
- Encryption and Key Management – HYOK and FIPS 140‑3 Validation
Kiteworks supports Hold Your Own Key (HYOK) encryption, giving DIB customers full ownership of their cryptographic keys. This reduces audit scope and third‑party exposure, but it also places the burden of key management squarely on your organization. The platform is FIPS 140‑3 validated, ensuring that cryptographic modules meet the stringent standards required for protecting CUI.
Step‑by‑step guide to implementing HYOK and FIPS‑compliant encryption:
- Generate and store encryption keys in a Hardware Security Module (HSM) or a secure key management system (e.g., AWS KMS with customer‑managed keys).
- Configure Kiteworks to use HYOK: In the platform’s administration console, select “Hold Your Own Key” and provide the key alias or ID from your HSM/KMS.
- Enable encryption for all data at rest and in transit: Ensure that CUI is encrypted using AES‑256 (or stronger) when stored, and TLS 1.2/1.3 when transmitted.
- Document key management procedures: Include key generation, rotation, backup, and destruction policies in your SSP.
- Regularly test key recovery procedures to ensure you can restore access to encrypted data in the event of a key compromise or loss.
Linux command to verify TLS 1.2/1.3 support and cipher suites:
Check supported TLS versions and ciphers on a web server openssl s_client -connect your-kiteworks-server.com:443 -tls1_2 openssl s_client -connect your-kiteworks-server.com:443 -tls1_3 List all available ciphers and filter for FIPS-compliant ones openssl ciphers -v 'ALL:!aNULL:!eNULL' | grep -E 'TLS_(v1.2|v1.3)'
Windows command to check TLS settings:
Check TLS 1.2/1.3 registry settings Get-ChildItem "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp" | Select-Object
- Continuous Monitoring and Audit Logging – Satisfying AU Controls
The Audit and Accountability (AU) control family requires that you generate, protect, and retain audit records that enable the detection of unauthorized access, modification, or destruction of CUI. Kiteworks provides comprehensive audit trails for every send, share, receive, and use of private data.
Step‑by‑step guide to setting up continuous monitoring:
- Enable detailed audit logging on all systems that handle CUI, including operating system logs, application logs, and network device logs.
- Centralize log collection using a Security Information and Event Management (SIEM) system or a log aggregation platform.
- Define retention policies: Retain logs for at least one year (or as required by your contract) and ensure they are stored in a tamper‑proof format.
- Establish alerting rules: Configure alerts for failed login attempts, privilege escalations, unauthorized file access, and configuration changes.
- Conduct regular log reviews: Assign personnel to review audit logs weekly and investigate anomalies promptly.
Linux command to configure auditd for CUI directory monitoring:
Add audit rules to monitor the CUI directory for access and modifications auditctl -w /cui_data -p rwxa -k cui_access Verify audit rules are loaded auditctl -l Search audit logs for events related to CUI ausearch -k cui_access --start today
Windows PowerShell command to enable advanced audit policies:
Enable auditing for file access in the CUI folder
auditpol /set /subcategory:"File System" /success:enable /failure:enable
Configure SACL on the CUI folder to log all access attempts
$acl = Get-Acl -Path "C:\CUI_Data"
$auditRule = New-Object System.Security.AccessControl.FileSystemAuditRule("Everyone", "FullControl", "Success", "Failure")
$acl.SetAuditRule($auditRule)
Set-Acl -Path "C:\CUI_Data" -AclObject $acl
What Undercode Say:
- Key Takeaway 1: The CMMC Phase II pause is not a reprieve – it is a window of opportunity to get your compliance house in order before the assessment machinery resumes. DFARS 252.204‑7012 and Phase I self‑assessment obligations remain in full force.
-
Key Takeaway 2: The Kiteworks‑A‑LIGN partnership provides a clean separation of duties: implement controls with Kiteworks, then validate with A‑LIGN. This independence is critical for maintaining the integrity of the C3PAO assessment process.
Analysis: This partnership addresses a fundamental pain point for DIB organizations: the chasm between implementing security controls and proving they work. Kiteworks reduces the technical burden by delivering a FedRAMP‑authorized, FIPS‑validated platform that covers the lion’s share of CMMC Level 2 controls out of the box. A‑LIGN, with its track record of nearly 100 CMMC Level 2 assessments, brings the assessment rigor and federal audit experience that DIB contractors desperately need. The 60‑day review period is a gift – use it to close evidence gaps, not to pause compliance efforts. Organizations that treat this as a strategic pause rather than a holiday will emerge ahead of competitors still scrambling when Phase II resumes.
Prediction:
- +1 DIB organizations that adopt the Kiteworks‑A‑LIGN framework within the next 60 days will achieve CMMC Level 2 certification 40‑50% faster than those that wait for the Phase II review to conclude.
-
+1 The partnership will set a new industry standard for “implementation + independent assessment” models, with other C3PAOs and platform vendors forming similar alliances to compete.
-
-1 Organizations that interpret the 60‑day pause as a compliance holiday will face severe remediation backlogs and potential contract disqualification when Phase II resumes with potentially stricter enforcement mechanisms.
-
-1 The Department of War’s review could introduce new evidence requirements or modified control interpretations, catching unprepared contractors off guard and extending their assessment timelines.
-
+1 Kiteworks’ HYOK encryption and single‑tenant architecture will become the de facto standard for CUI protection, as auditors increasingly flag multi‑tenant isolation as a high‑risk area requiring additional scrutiny.
-
+1 The partnership will accelerate the consolidation of compliance tools, reducing the current fragmentation where DIB contractors juggle multiple point solutions for file sharing, email encryption, MFT, and audit logging – all of which Kiteworks unifies.
