Cloud Infrastructure

Securing your cloud infrastructure could be considered as important as securing your decentralized application, as a lot of users will be interacting with your dapp through the cloud provider. Some best practices to consider are:
- Implement strict access controls and identity management to ensure that only authorized individuals can interact with cloud resources. Use role-based access control (RBAC) and multi-factor authentication (MFA).
- Encrypt data both in transit and at rest. Use managed encryption keys or bring your own keys (BYOK) for enhanced security.
- Configure virtual private clouds (VPCs), implement firewalls, and monitor network traffic to protect against unauthorized access and threats.
- Set up comprehensive logging, monitoring, and threat detection systems to identify and respond to security incidents in real-time. Use services like AWS CloudTrail, Azure Monitor, and Google Cloud Logging.
- Implement high availability, data backup, and disaster recovery plans to protect against service disruptions. Use automated failover and replication strategies.
- Ensure compliance with regulatory requirements (e.g., GDPR, MiCA).
