S3 Security Tips for Noobs 🥷

Congrats, noob!

You’ve got buckets 🪣, objects 📂, and even a mini website 🌐.
But now comes the serious stuff: keeping your cloud fortress safe.

S3 is powerful, but if you’re careless, your memes, projects, or sensitive files could leak to the world 🌍😱.

1. Don’t Leave Buckets Public 🌎🚫

• Always check bucket permissions
• Public = anyone on the internet can access your files
• Analogy: Leaving your house unlocked while sleeping 😴🏠

2. Use IAM Roles Instead of Keys for Apps 🧑‍💻

• Instead of giving your app AWS keys, attach IAM roles
• Safer and easier to manage
• Analogy: Give your app a VIP badge instead of the master key 🔑

3. Enable Encryption 🔒

• Server-side encryption (SSE) protects your files at rest
• Types: SSE-S3, SSE-KMS, SSE-C
• Analogy: Put your treasures in a locked safe inside the bucket 🗝️

4. Versioning + MFA Delete ⏳

• Enable versioning → rollback if someone messes with your files
• Optional: MFA Delete → requires multi-factor authentication for deletions

5. Monitor and Audit 📊

• Use AWS CloudTrail + CloudWatch to monitor access
• Spot suspicious activity early
• Analogy: Security cameras for your cloud mansion 📹

6. Least Privilege Principle 🎯

• Only give permissions that are necessary
• Avoid “full access” unless really required
• Analogy: Don’t give every friend a master key 🔑

Kahnu’s Pro Tip 💡
