Hosting bespoke software for clients on a secure Virtual Private Cloud (VPC) involves implementing best practices to ensure data security, reliability, and scalability. Here are some key best practices we follow at Atula:
VPC Design:
- Isolation : Use separate Virtual Private Clouds for development, testing, and production environments to ensure isolation and prevent unauthorized access.
- Subnet Structure : Organize subnets based on security requirements, separating public and private resources.
Security Groups and Network ACLs:
- Fine-Grained Access Control : Use security groups for instance-level access control and network ACLs for subnet-level control. Implement the principle of least privilege.
Data Encryption:
In-Transit Encryption : Enable SSL/TLS for data in transit. Use secure communication protocols (HTTPS, SSH) for accessing resources.
At-Rest Encryption : Implement encryption for data at rest, especially for databases and storage.
Identity and Access Management (IAM) :
-
Role-Based Access Control (RBAC) : Implement IAM roles with the principle of least privilege to control access to AWS resources.
-
Multi-Factor Authentication (MFA) : Enforce MFA for enhanced security of user accounts.
