Check your website security using ASafaWeb

Troy Hunt, the creator of the great ebook about the OWASP Top 10 specifically targeted at .NET developers has built a great tool to check your website security: ASafaWeb.

What’s ASafaWeb?
“ASafaWeb is the Automated Security Analyser for ASP.NET Websites. The purpose of ASafaWeb is to make scanning for common configuration vulnerabilities in live ASP.NET websites dead easy. To that effect, you don't need anything more than a URL to get started and ASafaWeb will head off and report on anything it can find which is remotely detectable.”
Whilst this is an unequivocally a basic tool, it will still find configuration flaws in many web sites. The sort of flaws it finds are things like custom errors being off, YSODs with stack traces being returned, tracing still on, debug mode enabled and many, many more.
How does it work?

  • Enter the url of your application and click Scan. Can it be any easier? (I tried it with my employer's website Glimlach).

  • Once the scan has completed, you get a nice summary report and details about all the scanned parts, problems and possible ways to fix them. Nice!

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
