The Modern .NET Show
Show Notes Hey everyone, and welcome back to The Modern .NET Show; the premier .NET podcast, focusing entirely on the knowledge, tools, and frameworks that all .NET developers should have in their toolbox. I'm your host Jamie Taylor, bringing you conversations with the brightest minds in the .NET ecosystem. This episode is a super important, top-of-the-heap, bonus episode that you definitely need to be listening to. I, basically, reached out to Hayden Barnes, who we've just now had on the show to talk about .NET never-ending support and what happens when you drop out of support with Microsoft....

Show Notes "There's a good chance it's not gonna flag for you that, you, know your point of sale system is on .NET six and is now vulnerable, you know. So to a certain extent, companies often aren't even aware and this is something I've learned to be in this space. They're not...

Show Notes "It's not just guessing. It's not just saying, "oh, there's something to log in. I think we'll call the button login." It actually knows the button is called Login, it's seen it. So that makes a big difference and makes it much more resilient. So that's definitely a big...

And in the end, that's how customers interact with Azure is through APIs. And so it's important to have that contract so that...

How well it can do it Is based upon what kind of CPU you have. What kind of CPU they have since have it in miniature...

So sometimes you'll go to graph, it's a little bit harder for us to write the code for around it, but the bandwidth consumption is considerably smaller. the compute consumption and the ability for it to...

Show Notes "Yeah, exactly. In fact, one of the central premises of Dapr has, you know, one of its goals is not only to be multi-language, in that anyone can use the APIs from any language they come from. So it has SDKs. First, you can call it HTTP if that's all you care about. But it has SDKs for Java, JavaScript, of course, .NET, Python,...

Show Notes
"This should be a mantra for anyone working on web applications or web APIs: you should validate any input of the application as much as possible. When you conceptualize it, all the malicious input into your application comes across in an HTTP request at some point. It's either in the URL or in the body. That's generally speaking, unless you have a supply chain attack, that's generally the vector by which your application will be attacked. Before you even start to kind of think about specific vulnerabilities, if you narrow down what is permissible input right out of the gate, then you kind of close the door on so many different vulnerabilities without even thinking about it."— Malcolm McDonald
Welcome friends to The Modern .NET Show; the premier .NET podcast, focusing entirely on the knowledge, tools, and frameworks that all .NET developers should have in their toolbox. We are the go-to podcast for .NET developers worldwide, and I am your host: Jamie "GaProgMan" Taylor.
In this episode, Malcolm McDonald joined us to talk about the importance of Application Security, knowing the basics of secure coding, and backing that all up with both "secure by default" designs, and subscribing to CVE notifications.
"So what you find in your career is that if you set down kind of sensible default behaviour in your codebase earlier on, then everyone will follow that. You establish, kind of, best practices. It might take a little bit longer, but if you say, "this is the way we do this over here," then even yourself when you, kind of, come back to, will kind of, reproduce that path. So the initial, kind of, like first few check-ins to your source control are key to, like, establishing best practice"— Malcolm McDonald
One note before we begin: some of Malcolm's audio is a little rough. Mark, our superstar editor, has done what he can, but there are parts that might be a little unclear. If you have trouble with the audio, please remember that there is a full transcription linked in the accompanying show notes.
Anyway, without further ado, let's sit back, open up a terminal, type in `dotnet new podcast` and we'll dive into the core of Modern .NET.
