Day 22: Configuring Secure SSH Access to an EC2 Instance | 100 Days of Cloud (AWS) | Kodekloud

As part of my ongoing 100 Days of Cloud (AWS) journey with KodeKloud, I am documenting my daily progress and sharing lab solutions to help the community grow alongside me. Today’s challenge focuses on a fundamental pillar of cloud security: Configuring Secure SSH Access. Why Secure SSH Matters By default, AWS EC2 instances are launched in a "locked down" state. To manage your virtual servers via the command line, you must establish an encrypted communication channel. Configuring secure SSH (Secure Shell) is the process of creating a private "handshake" between your local machine and your AWS instance. The goal is simple but critical: Grant seamless access to authorized users while keeping the rest of the internet out. Key Takeaways from the Lab: Identity Verification: Using key pairs to prove identity without transmitting passwords. Security Groups: Implementing the principle of least privilege by restricting port 22 access to specific IP ranges. Encrypted Tunneling: Ensuring all commands and data sent to the instance are shielded from eavesdropping. I’m always looking to refine my approach—if you have tips on SSH hardening or AWS security best practices, let's chat in the comments! A huge shoutout to KodeKloud for these incredible free DevOps practice labs. Sharing these solutions is my way of giving back to the community that makes learning so accessible.
