Walls & Vaults: Data Protection & Networking

Sat, 16 May 2026 00:00:00 +0000

In Part 1, we covered identity and access. In Part 2, we went through the security services that protect, detect, and audit your environment. Now comes the last piece of Domain 1 — protecting the data itself and building a secure network around it.

This part has two halves: encryption and secrets management (how you protect data at rest and in transit) and VPC networking (how you control the flow of traffic). Both show up heavily on the exam.

Guarding the Cloud: Security Services & Auditing

Fri, 15 May 2026 00:00:00 +0000

In Part 1, I covered the identity side of Domain 1 — IAM, STS, Cognito, Organizations, and all the services that control who gets in and what they’re allowed to do. Now comes the next layer: how do you protect what’s inside, detect threats, and audit everything?

AWS has a surprisingly deep set of security tools. Some are for prevention, some for detection, some for compliance. Knowing which one does what — and when to use each — is a big part of Domain 1.

AWS SAA-C03: Identity & Access Management

Thu, 14 May 2026 00:00:00 +0000

I’ve been studying for the AWS Solutions Architect Associate (SAA-C03) exam, and I’m honestly excited to finally sit for it. It’s been a while since I started preparing, but I’m getting the vibes now and fully locked in.

Since I learn better when I write things down, I figured I’d turn my notes into blog posts. Forces me to actually make sense of what I’ve read instead of just skimming. If it helps someone else along the way, even better.
