Threat Modeling for Developers
Threat modeling doesn't have to be a heavyweight ceremony run by a separate security team. Here's how developers can fold lightweight, per-feature threat modeling directly into pull requests and sprint work.
Secure Design Principles Every Team Should Know
Secure design principles are the durable rules of thumb — least privilege, fail securely, defense in depth, secure defaults — that keep systems safe by construction rather than by patching. Here's the working set and how to apply them.
The Principle of Least Privilege, Explained
Least privilege means every user, service, and process gets exactly the access it needs to do its job — and nothing more. Here's why it contains breaches and how to implement it without breaking things.
Authentication vs Authorization: What's the Difference?
Authentication proves who you are. Authorization decides what you're allowed to do. One is the ID check at the door; the other is the list of rooms you can enter.
What Is Software Composition Analysis (SCA)?
Software Composition Analysis (SCA) identifies the open source and third-party components in your code, then flags their known vulnerabilities and license risks. Here's how SCA works and what separates modern tools from legacy scanners.
What Is Threat Modeling?
Threat modeling is the structured practice of asking what can go wrong with a system before you build it, then designing controls to match. Here's the four-question framework, how to run a session, and where it fits supply chain security.
What Is the MIT License? A Plain-English Guide
The MIT License is one of the shortest and most permissive open-source licenses in existence. Here is exactly what it lets you do, what it requires, and what it means for compliance.
What Is the Apache 2.0 License? A Complete Guide
The Apache License 2.0 is a permissive license with an explicit patent grant and a few conditions that set it apart from MIT and BSD. Here is what it permits, requires, and means for compliance.
What Is SLSA? Supply-chain Levels for Software Artifacts Explained
SLSA is an open framework of graded security levels for build integrity, letting teams prove how a software artifact was produced. Here's how the Build track levels work and how to reach them.
What Is Secrets Management?
Secrets management is the practice of securely storing, distributing, rotating, and auditing the credentials your software needs to run. Here's how it works, why leaked secrets are a top breach vector, and how to get it right in 2026.
What Is a Vulnerability? A Plain-English Guide
A vulnerability is a weakness in software that an attacker can misuse to do something they shouldn't. Here's what that means, why it matters, and how teams find and fix them.
What Is a CVE? Understanding Vulnerability IDs
A CVE is a unique public ID given to a specific known security weakness, so everyone can talk about the same flaw without confusion. Here's how the system works.
