What’s the best way to automatically blacklist IPs in Kubernetes?

Asked By CuriousCoder99 On

I'm setting up ingress for my Kubernetes cluster and I've noticed there are a lot of blacklists out there for IP addresses known to be associated with attackers and spammers. Is there a service that can automatically pull these lists to block these IPs from accessing my ingresses? Additionally, can I use something like fail2ban to blacklist IPs, even though each pod is different?

Yeah, Crowdsec does exactly what you need! It can automate the blacklisting of malicious IPs and offers integration that works well with Kubernetes.

Crowdsec is a great tool for what you're looking to achieve! It provides lists of malicious IPs and can help you block additional IPs, similar to what fail2ban does, using either managed or custom rules.
