#667 Re-designing Highly-Important Infrastructure to be Secure from the Start

#667 If we were to start all over again, discussion how the power grid, communications grid, utilities infrastructure and computing could be designed from the start to be secure from outside tampering and harm.

Designing a secure and resilient infrastructure for power, communications, utilities, and computing from the ground up is a complex and multifaceted challenge. However, there are several key principles and best practices that could be applied to achieve this goal. Below are some considerations for designing secure and resilient infrastructure:

1. Defense-in-Depth: Implement multiple layers of security controls to protect the infrastructure. This approach ensures that if one layer of defense is breached, additional layers are in place to prevent further compromise. Defense-in-depth can include physical security measures, network segmentation, encryption, authentication, intrusion detection, and more.
2. Zero Trust Architecture: Adopt a zero trust approach to network security, where all users, devices, and network traffic are considered untrusted by default. Access to resources is granted based on strict identity verification and least privilege principles, meaning that users and devices are only granted access to the resources they need to perform their tasks.
3. Redundancy and Resilience: Design the infrastructure to be resilient to failures and attacks. This can include building redundancy into critical systems, such as having backup power sources, redundant communication links, and failover mechanisms. Additionally, infrastructure should be designed to continue operating even in degraded mode during an attack or failure.
4. Secure-by-Design: Security should be integrated into the design and development process from the very beginning. This includes conducting threat modeling, security risk assessments, and secure coding practices. Security features should be built into the infrastructure rather than being added as an afterthought.
5. Regular Testing and Auditing: Conduct regular security testing, including penetration testing and vulnerability assessments, to identify and address potential weaknesses in the infrastructure. Additionally, conduct regular audits to ensure compliance with security policies and standards.
6. Supply Chain Security: Ensure the security of the supply chain for hardware and software components used in the infrastructure. This includes vetting suppliers, verifying the integrity of components, and ensuring secure delivery and installation.
7. Incident Response and Recovery: Develop and maintain a comprehensive incident response plan to quickly detect, respond to, and recover from security incidents. This includes having a dedicated incident response team, clear communication protocols, and predefined recovery procedures.
8. Continuous Monitoring: Implement continuous monitoring and logging of network traffic, system activity, and user behavior to detect and respond to suspicious or anomalous activity. Use security information and event management (SIEM) tools to aggregate and analyze security data.
9. User Education and Awareness: Train all users, including employees, contractors, and third parties, on security best practices and the importance of protecting the infrastructure. Educate users on how to recognize and report suspicious activity, phishing attempts, and other security threats.
10. Collaboration and Information Sharing: Foster collaboration and information sharing among different stakeholders, including government agencies, industry partners, and security researchers. Sharing threat intelligence and best practices can help improve the overall security posture of the infrastructure.
11. Regulatory and Legal Frameworks: Establish clear regulatory and legal frameworks to define security requirements, standards, and responsibilities for all stakeholders involved in the operation and maintenance of the infrastructure. This includes setting penalties for non-compliance and incentivizing the adoption of security best practices.

It's important to note that achieving perfect security is not possible, and the threat landscape is constantly evolving. Therefore, a proactive and adaptive approach to security is essential to keep pace with emerging threats and vulnerabilities. Additionally, the design and implementation of secure infrastructure should be guided by a risk-based approach, where security measures are prioritized based on the potential impact and likelihood of threats.
