Part 6. Challenges and Solutions with CDHA

Updated: May 28

Innovation often faces hurdles, and the Cross Domain Hybrid Application (CDHA) architecture is no exception. Resistance to new technologies frequently arises from misunderstandings, such as the misperception of it being merely another gateway, or concerns about its complexity and potential security vulnerabilities. Addressing these misconceptions with clear and factual responses is crucial. In this blog, we confront prevalent myths surrounding CDHA, offering insights and solutions to overcome challenges effectively. 



"CDHA is Just Another Gateway" 

CDHA is much more than a gateway. Unlike traditional gateways, which primarily control access between security domains and protect high trust domains, CDHA is a comprehensive framework ensuring secure data management across both low and high trust domains. It combines robust encryption, secure data transfer protocols, and advanced key management to provide end-to-end security. Beyond access control, CDHA integrates advanced cryptographic techniques to secure data throughout its lifecycle, not just during transfer between domains. CDHA ensures data integrity and confidentiality through row-level AES encryption and stringent validation processes. 


"CDHA is Too Complex" 

Complexity is another concern often associated with CDHA. However, understanding its depth is the key to unlocking its full potential. To achieve maximum security posture, CDHA should be implemented from the design phase, adhering to the secure by design principle. For existing architectures, CDHA’s components can be implemented to enhance its security, offering substantial improvements. 


"CDHA Has Potential Security Vulnerabilities" 

Security is paramount in any technological solution, and CDHA is no exception. Addressing concerns about potential vulnerabilities, CDHA incorporates robust security features, including encryption protocols, access controls, and threat mitigation strategies. By implementing best practices and staying vigilant, organisations can harness CDHA’s security capabilities to safeguard sensitive data and mitigate cyber threats effectively. CDHA employs a multi-layered security approach, including row-level AES encryption, Elliptic Curve Diffie-Hellman (ECDH), and Elliptic Curve Digital Signature Algorithm (ECDSA) to protect data both at rest and in transit. It is continuously monitored to address emerging threats and vulnerabilities, ensuring it remains a robust security solution. However, there is a residual risk that user machines could be compromised, potentially exposing data or parts of decrypted data to hostile actors. CDHA employs gateway scans and other security measures to prevent any exploited data or information from traveling to the high trust domain. 


Managing Cryptographic Keys 

CDHA features an advanced key management system that simplifies the generation, storage, and usage of cryptographic keys. This system ensures that keys are securely managed and easily accessible to authorised users. Our unique solution provides users with keys automatically, eliminating the need for them to manage these keys themselves. This seamless key distribution simplifies the user experience while maintaining robust security. 

CDHA facilitates secure data transfer and communication between low and high trust domains, enhancing operational efficiency and collaboration. CDHA helps organisations meet regulatory requirements and standards, ensuring compliance with data protection laws and policies. 

CDHA is designed to address the complexities and security challenges of managing data across diverse security domains. By clarifying misconceptions and providing solutions to implementation challenges, CDHA demonstrates its transformative potential. Organisations can leverage CDHA to enhance security, streamline data management, and achieve their strategic goals. 

Stay tuned for more insights as we continue to explore the future of CDHA in our upcoming blog series.
