A server placed between an organization’s private network and the public internet is known as a bastion host. By granting just specific and authorized users access, it enhances security.A bastion host usually refers to a severely limited and closely monitored server that allows access to a private network from the public internet.As secure gateways, bastion hosts provide remote access to private networks via secure connections like Secure Shell (SSH) and Remote Desktop (RDP) while ensuring robust authentication and defense against cyberattacks. In order to help users in identifying attacks or security incidents, Bastion hosts are also equipped with logging and monitoring in their underlying operating system.Through protected channels, Bastion Host provides authorized users restricted access. It permits authorized users to have secure access.According to experts, Bastion servers are a more accurate and auditable access mechanism that enforce least-privilege access by granting users authority over particular resources rather than the entire network.In cloud environment, a bastion server acts as a regulated point of entry for resources or virtual machines (VMs) located in private subnets, which are not immediately accessible from the internet.
