Having basic cyber hygiene Advanced technology is important, but basics like regular data backups, software updates, strong password policies, and multi-factor authentication are fundamental. For instance, hardware- or software-based firewalls can monitor incoming and outgoing network traffic and block suspicious activity.

Kubernetes nodes rely on underlying virtual servers for both the master control plane and for worker nodes. 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.

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.
