What’s a secure password?

As a consultant I visit a lot of companies. At most of these companies I have an account and associated password. Every company has it’s own set of password rules most of the time expecting a combination of letters, numbers, uppercase, lowercase and special characters. But how useful are these password policies and in what ways does it help to make my password hard to crack?

There are a lot of misconceptions regarding passwords and what a lot of people think is a secure password in the end is not. For example, do you think that “P@ssw0rd1!” is a more secure password than “This is my password”? (At least what I know, is that the second one is a lot easier to remember.)

Let’s use Haystack to get the answer:

“Haystack is an interactive brute force search space calculator that allows you to experiment with password length and composition to develop an accurate and quantified sense for the safety of using passwords that can only be found through exhaustive search.”

First check “P@ssw0rd1!” :

Let’s now check “This is my password”:

Is this what you expected? Glimlach

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...
