What are the general steps for creating a bastion host?

To create a bastion host, first, set up a virtual machine (VM) in a secure network segment, typically within a private subnet. Next, configure the VM with a hardened operating system and install necessary security tools, like firewalls and intrusion detection systems. Then, restrict access by allowing only specific IP addresses through security groups or firewall rules, and use SSH keys for authentication. Finally, regularly update and monitor the bastion host to ensure it remains secure and compliant.
