Security Best Practices :-

1. Use IAM Roles: Assign least-privilege IAM roles to your instances.
2. Regular Updates: Keep your instance’s OS and applications updated.
3. Security Groups: Implement the least permissive rules for your security groups.
4. Encryption: Use encrypted EBS volumes and snapshots.
5. Key Management: Protect your EC2 key pairs and use strong passwords.

Steps to Launch and Connect to an EC2 Instance :-

Step 1: Sign In to AWS Management Console

1. Go to the AWS Management Console.
2. Sign in with your AWS credentials.

Step 2: Launch an EC2 Instance

1. Navigate to the EC2 Dashboard by selecting Services > EC2.
2. Click on Launch Instance.
3. Choose an Amazon Machine Image (AMI):
   • Search for “Ubuntu” and select the desired version.
4. Choose an Instance Type:

Conclusion

In this project, we learned how to:

1. Launch an Ubuntu EC2 instance on AWS.
2. Apply security best practices to ensure the instance is secure.
3. Connect to the EC2 instance using PuTTY.

This project demonstrates the practical steps involved in setting up and securing a cloud-based server, which is a valuable skill in today’s tech landscape.
