IoT device security fundamentals: firmware integrity, credentials, and network isolation
One hardcoded Telnet password list built a 100,000-device botnet in 2016. A decade later, the same three failures still define most IoT breaches.
The AWS migration security checklist: IAM, encryption, and network segmentation
A misconfigured WAF and an over-permissioned IAM role exposed 106 million records in 2019 — here's the checklist that prevents a repeat during your AWS migration.
Unified identity, segmentation, and policy-as-code for multi-cloud
38% of breaches start with stolen credentials, per Verizon's 2024 DBIR — the fix for multi-cloud estates is unified identity, segmentation, and policy-as-code, not per-provider IAM.
What Are Kubernetes Network Policies
Kubernetes clusters default to flat, all-to-all pod networking. Here's how NetworkPolicy objects, CNI enforcement, and default-deny rules actually stop lateral movement.
How to configure Kubernetes network policies
A step-by-step guide to configuring Kubernetes network policies: enabling Calico, building a default-deny baseline, allow-listing traffic, and verifying enforcement.
What is Network Segmentation
Network segmentation limits breach blast radius by isolating systems into enforced zones. Learn the types, common mistakes, and how to implement it in hybrid clouds.
How to implement network segmentation in a data center
A step-by-step guide to network segmentation best practices in the data center: mapping traffic, VLANs, microsegmentation, least-privilege rules, and verification.
How to configure network ACLs in AWS VPC
A step-by-step guide to configure AWS NACLs correctly — creating rules, associating subnets, and verifying traffic — for real defense-in-depth in your VPC.
Network Segmentation for Development Environments: Isolating the Build Pipeline
Development environments are often the weakest link in network security. Proper segmentation isolates build systems from production and prevents lateral movement from compromised developer machines.
