Good morning, Edwin,
I understand your concerns about security, especially with your previous experience on the AWS Free Tier. It’s
essentialto approach this with a strategy that enhances security while using AWS or any other cloud service. Here are a
fewsteps to help you safeguard your environment:
1. Strong Access Controls: Always use strong, unique passwords for your AWS account and databases. Implement
Multi-FactorAuthentication (MFA) to add an extra layer of security.
2. Minimal Privilege Principle: Assign the least privilege necessary to your AWS roles and permissions. This
limitspotential damage if an account is compromised.
3. Security Groups and Network ACLs: Configure these to control inbound and outbound traffic to your instances
strictly.This helps prevent unauthorized access.
4. Regular Monitoring and Audits: Use AWS CloudTrail and other monitoring tools to keep track of activities and
detectunusual access patterns or potential security threats.
5. Data Encryption: Use AWS’s built-in tools to encrypt your data at rest and in transit. This ensures that your
datais secure, even if intercepted.
Regarding your interest in installation exercises, while AWS does offer pre-built options, you can also configure
customPostgreSQL installations on EC2 instances. This allows you to practice installation, configuration, and
managementas if you were handling a server in your own data center.
I hope these tips help you feel more confident in using cloud environments securely. Wishing you the best in your
learningjourney!
Best regards,
Sondra
