From Risk to Resilience: Secure Azure IoT for Manufacturing
From Risk to Resilience: Secure Azure IoT for Manufacturing
CASE STUDY
Business Overview
A leading manufacturing company developed a feature-rich Azure IoT application to enable secure remote monitoring of their operations. The solution was designed to support large-scale deployment and compliance with industry standards.
Challenge
During a vulnerability assessment, the application was found to have 27 critical security issues. These gaps needed to be remediated in order to:
- Obtain NIST 800 certification for production release.
- Ensure a secure and compliant transition into post-production operational support.
Solution
NeST Digital implemented a structured security remediation and compliance framework:
- Conducted a gap analysis against NIST 800 standards.
- Remediated all identified vulnerabilities through secure coding, configuration hardening, and architectural improvements.
- Prioritized implementation of key security controls, including:
- Secure firmware management
- Over-the-air (OTA) updates
- Trusted Platform Module (TPM) attestation
- Operating system (OS) hardening
- Encryption of data in transit and at rest
- Incorporated these controls as backlog features in the product roadmap.
- Adopted Azure Sentinel as the SIEM tool to provide centralized monitoring, analytics, and incident detection.
- Established a post-production support model with continuous monitoring, vulnerability scanning, and incident management.
Business Impact
- 100% closure of all 27 vulnerabilities.
- Achieved NIST 800 certification, enabling production release.
- Delivered robust compliance assurance and improved operational security.
Outcomes achieved:
- Security Attacks: 0
- Regulatory Compliance: 100%
- Data Privacy: 99.9%
- MTTR (Mean Time to Resolution): < 6 hours
