Networking. Via Ivan Pepelnjak, I was pointed to Jon Langemak’s in-depth discussion of working with Linux VRFs. The first is a post on Cilium and F5 load balancer integration , while the second discusses implementing Kubernetes network policies with Cilium and Linkerd. I hope that you find something useful here.

It is important to use security tooling such as OpenSCAP, the open source version of the Security Content Automation Protocol, to harden virtual machine images prior to their deployment in virtual private clouds. With cloud virtualization and advanced networking, vacating a cluster after the initialization of a new one is feasible.

So what then makes IoT hacking different from say traditional network hacking. And it's not just stories from the authors themselves.

Instead of relying on a central authority, the blockchain is maintained by a network of participants, known as nodes, who collectively validate and verify transactions. Different blockchain networks may use various consensus algorithms such as proof-of-work (PoW), proof-of-stake (PoS), or other innovative protocols to achieve consensus.
