This includes scanning for vulnerabilities in code, dependencies, and containers before deployment. 2.19. Immutable Infrastructure: Immutable Deployments: Embrace the concept of immutable infrastructure, where servers and application components are replaced rather than updated. This minimizes the attack surface and simplifies security patching by deploying entirely new, patched instances. 2.20. Chaos Engineering: Security Chaos Engineering: Apply chaos engineering principles to security by actively testing how your system behaves under controlled security failures. Identify vulnerabilities and enhance your system's resilience. 2.21. Secure Credential Management: Secrets Management: Implement a secure secrets management solution to store and manage sensitive information like API keys, passwords, and tokens. Ensure that credentials are never hardcoded in code repositories. 2.22. Regulatory Compliance Automation: Continuous Compliance Checks: Automate compliance checks to ensure that your infrastructure and applications adhere to regulatory standards and internal policies continuously. Compliance Reporting: Generate compliance reports and audit trails automatically to demonstrate adherence to regulatory requirements. 2.23. Container Orchestration Security: Kubernetes Security: If using container orchestration platforms like Kubernetes, secure the cluster configurations, apply RBAC, and implement network policies to restrict communication between containers and pods. 2.24. Threat Modeling at Scale: Automated Threat Modeling: Explore automated threat modeling tools that can analyze code and infrastructure at scale, providing insights into potential vulnerabilities and threats across your entire environment. 2.25. Secure Cloud-Native Services: Utilize Cloud-Native Security Services: Leverage security services provided by cloud providers, such as AWS GuardDuty, Azure Security Center, or Google Cloud Security Command Center, to monitor, detect, and respond to security threats. 2.26. Continuous Security Feedback Loop: Incident Feedback: After addressing security incidents, ensure that lessons learned are integrated into your security practices. Use incidents as opportunities to improve security controls and processes. 2.27. Red Team Testing: Periodic Red Team Exercises: Conduct periodic red team exercises where skilled ethical hackers simulate attacks on your systems. Red teaming can help uncover vulnerabilities and weaknesses in your security posture. 2.28. Security Champions Program: Expand Security Champions: Extend the security champions program to include members from various departments. Encourage contributions from non-security teams to foster a broader security perspective. 2.29. Third-Party Risk Management: Vendor Security Assessment: Continuously assess the security posture of third-party vendors and service providers. Ensure they meet your security standards and align with your risk tolerance. 2.30. Incident Response Automation: Automate Incident Handling: Automate incident response processes wherever possible. Implement playbooks and workflows that guide the response to common security incidents, reducing response times. 2.31. Threat Intelligence Integration: Proactive Threat Intelligence: Stay informed about emerging threats and vulnerabilities by integrating threat intelligence feeds and services into your security monitoring. Use this information to adapt your security controls proactively. 2.32. Continuous Compliance Monitoring: Real-time Compliance Checks: Implement real-time compliance monitoring to ensure that security policies and configurations remain in compliance throughout the application lifecycle.
