3.7 MAINTENANCE

By W. Noble 📅 2024-03-02

NIST 800-171 control 3.7, focuses on secure system maintenance practices. It mandates controls for all maintenance activities, including those performed off-site. This ensures equipment is sanitized of sensitive information before removal and that diagnostic tools are checked for malicious code. Additionally, multi-factor authentication and supervision are required for remote maintenance sessions. These measures aim to protect confidentiality and availability of critical information during system maintenance.

NIST 800-171, a critical security standard, outlines a specific set of requirements to safeguard Controlled Unclassified Information (CUI) within nonfederal information systems and organizations. One crucial section, 3.7 MAINTENANCE, focuses on maintaining the effectiveness of these security controls.

The 3.7 MAINTENANCE requirements emphasize the importance of a structured program for maintaining your organization's security controls. This program should involve regular assessments to determine if the controls are working as intended. These assessments should pinpoint any weaknesses and suggest improvements to ensure the controls remain aligned with current threats and vulnerabilities. NIST 800-171 doesn't just require identifying issues; it also mandates the timely remediation of any security control deficiencies that are found.

By following these 3.7 MAINTENANCE requirements, organizations can ensure their security controls are continuously effective in safeguarding CUI. This proactive approach helps mitigate risks and prevents potential security breaches.
