Achieving DoDIN & Common Criteria Certification for Network Security in a SPM Product

Introduction

This case study details the engineering journey undertaken for a leading Security Posture Management (SPM) product company to achieve Department of Defense Information Network (DoDIN) and Common Criteria certifications for network security. These certifications are highly sought after by companies serving the Defense & Federal domain, signifying a product’s adherence to rigorous security standards.

Challenge

Obtaining DoDIN and Common Criteria certifications requires a deep understanding of both security protocols and the specific requirements outlined in the certification documentation. Here’s a breakdown of the challenges encountered:

  • Identifying Security Gaps: A comprehensive analysis was necessary to pinpoint vulnerabilities within the SPM product that could potentially compromise network security.
  • Remediation and Verification: Identified vulnerabilities needed to be addressed through secure coding practices, code reviews, and penetration testing. Additionally, verification of these fixes across various communication channels was crucial.
  • Cryptographic Communication Security: Ensuring all network sessions utilized robust cryptographic protocols to protect sensitive data in transit.
Technical and Domain Knowledge Required

Successfully navigating the path to DoDIN and Common Criteria certifications necessitated expertise in the following areas:

  • Network Security Principles: A thorough understanding of network security concepts like firewalls, intrusion detection/prevention systems (IDS/IPS), and secure communication protocols (HTTPS, SSH) was essential.
  • DoDIN Security Requirements: In-depth knowledge of the DoDIN Security Requirements Guide (DISRG) was required to comprehend the specific security controls and best practices applicable to the product.
  • Common Criteria Framework: Familiarity with the Common Criteria for Information Technology Security Evaluation (CCITSEC) framework was crucial for understanding the evaluation process and tailoring the product to meet the Evaluation Assurance Levels (EALs).
  • Secure Coding Practices: Implementing secure coding practices to minimize vulnerabilities was essential. This included techniques like input validation, buffer overflow protection, and secure use of cryptographic libraries.
  • Penetration Testing: Conducting thorough penetration testing using industry-standard methodologies helped identify and address potential security flaws.
  • Communication Security Protocols: Expertise in cryptographic protocols like Transport Layer Security (TLS) and Secure Shell (SSH) was necessary to ensure secure data transmission across various communication channels.
Solution

The engineering team embarked on a multi-phased approach:

  • Vulnerability Assessment: A comprehensive security assessment identified vulnerabilities within the SPM product’s code and network communication channels.
  • Remediation and Verification: Identified vulnerabilities were addressed through secure coding practices, code reviews, and penetration testing. Fixes were verified across various communication channels (e.g., web traffic, application programming interfaces (APIs)) to ensure effectiveness.
  • DoDIN and Common Criteria Compliance Mapping: The team mapped the product’s security features and functionalities to the specific controls outlined in the DoDIN Security Requirements Guide (DISRG) and the Common Criteria framework.

Documentation and Evidence Collection: Extensive documentation detailing the implemented security controls, testing procedures, and results was prepared to support the certification process.

Impact

By achieving DoDIN and Common Criteria certifications, the SPM product now boasts:

  • Enhanced Credibility and Trust: These certifications demonstrate the product’s commitment to rigorous security standards, fostering trust within the Defense & Federal market.
  • Compliance with Regulations: DoDIN certification ensures compliance with stringent security regulations governing data handling within the Department of Defense.
  • Improved Network Security Posture: The rigorous testing and verification processes associated with these certifications contribute to a more secure network environment for Defense & Federal organizations.
Conclusion:

This case study underscores the significance of technical expertise and domain knowledge in achieving DoDIN and Common Criteria certifications for network security in a SPM product. By demonstrating a commitment to the highest security standards, the team was able to position this product to serve the unique needs of government agencies and defense contractors.
