We don’t just write C# code to make things run—we write it to keep trouble out. Attackers poke at every edge, looking for mistakes we might’ve missed. That’s why we drill secure coding standards into our process. These aren’t just…
Secure coding in C# and .NET means building applications with security baked into every step, not treating it as an afterthought. Every line of code, whether it’s handling user input, making a database call, or storing sensitive data, carries potential…
We remember the first time we saw an unhandled promise rejection crash a Node.js server. It was late, and we were debugging a user registration flow. One missing try-catch, and the whole process folded. The logs were useless. The stack…
We see a lot of folks breeze past session security when building with Node.js and Express, thinking the default setup will cover them. It won’t. Sessions are how we know who’s who, but if we don’t lock them down, attackers…
We work with npm packages every day—they’re the backbone of most JavaScript projects. But every shortcut comes with a risk. Vulnerabilities in these packages can slip in quietly, sometimes buried deep in the dependency tree. That’s why we teach our…
We see APIs take a beating—spikes in traffic, bots hammering endpoints, and attackers trying to brute-force their way in. That’s why we make rate limiting a core part of our Node.js security training. It’s not just about blocking bad actors;…
There was this moment—about two years back—when I was debugging what should’ve been a harmless bug. Our Node.js app kept returning odd values in a user permissions object. Took me a bit, but the root cause chilled me. Prototype pollution.…
We see a lot of folks jump straight into using the fs module for file work in Node.js, but that’s where trouble can sneak in if you’re not careful. Reading and writing files isn’t just about picking the right method—it’s…
We’ve all had that moment—some weird request hits our API, and everything just stops working. Maybe it was a missing field. Maybe it was a string where we expected a number. Or worse, a script tag slipped into a field…
We see command injection slip into Node.js projects more often than folks realize, especially when the child_process module gets involved. It’s easy to overlook, but letting user input touch shell commands—especially with exec—can give attackers a straight shot at your…
