Your First VPC Should Have This Layout
– Public subnet (load balancer only)
– Private subnet (app layer)
– Isolated subnet (databases)
– NAT gateway for controlled outbound
– Strict SG rules
This layout prevents careless exposure.

The Most Misunderstood AWS Concept
People think VPC is networking…
But it’s actually segmentation.
And segmentation is what keeps attackers from moving across your environment.

Lambda Security Checklist
– Use least-privilege IAM roles
– Turn on function-level logging
– Enable X-Ray
– Store secrets in Secrets Manager
– Add concurrency limits
Your functions need boundaries too.

Why Serverless Doesn’t Mean Secure
People think serverless = no servers = no security.
Truth:
Serverless removes infrastructure BUT increases identity-based attack risks.
Your biggest threat is over-permissioned Lambda roles.

5 S3 Hardening Steps Beginners Miss
– Block Public Access (GLOBAL)
– Enable default encryption (KMS if possible)
– Turn on Access Logs
– Use bucket policies only when required
– Enforce least privilege on IAM roles
Small changes → huge risk reduction.

S3 Is Not “Just Storage”
S3 is a full-blown access control challenge.
The real risk isn’t buckets…
…it’s misconfigurations:
– Public ACLs
– Unrestricted bucket policies
– No encryption
– No logging
Mastering S3 security is mandatory.

Why Least Privilege Is Harder Than It Sounds
Least privilege isn’t ‘give fewer permissions.’
It’s:
– No unused permissions
– No privilege inheritance
– No wildcard roles
– No human admins
It requires continuous refinement, not a one-time setup.

Authentication Testing Basics
Authentication testing evaluates how systems verify user identities. Key areas: credential handling, session management, MFA robustness, error feedback, and authorization overlaps. Use tools like Burp Suite ethically with permission. #CyberSecurity
