![]() ![]() By contrast, a bastion host gets specific attention to maintain the secure environment. In a standard virtual computer environment, unhealthy or unnecessary servers are discarded or replaced. This is necessary to provide an entry point for public networks into the network however, if the connection is compromised in the DMZ, the network is also compromised. The DMZ allows bastion hosts to be accessed by an external client. Bastion hosts are also fitted with logging and monitoring in their underlying operating system (such as Linux) to help you identify any attacks or security incidents.īastion hosts are encased in external firewalls within a demilitarized zone (DMZ). What is a bastion host?Īlso known as a jump box, a bastion host is a hardened computer meant to withstand cyberattacks: It will disable any unnecessary network services and run only the bare minimum of applications - such as a proxy server, load balancer, or firewall - in order to provide a connection, leaving far fewer attack vectors to be exploited. This article will cover bastion hosts in detail, address their use cases and limitations, and compare them to VPNs such as Tailscale - an alternative that can be superior in terms of latency and security. The primary difference between bastion hosts and VPNs is that a bastion host, by necessity, creates a single point of entry or failure, whereas a VPN creates separate encrypted private tunnels for each connection. It wasn’t until the advent of cloud computing, however, that these technologies could be delivered at scale. A VPN creates a private connection between two devices by creating an encrypted tunnel directly between the requesting device and its destination.īastion hosts and VPN technologies both emerged in the 1990s, and either can provide employees with a secure connection to their work environment. Another way to create a secure connection between users and company resources is by adding them to a virtual private network (VPN). A bastion host is usually a highly restricted and heavily monitored server that provides access from the public internet to a private network. ![]() There are many ways to provide a secure connection between users and company resources, one of which is through a bastion host. Giving employees the right tools to work securely is a critical step to protect your organization from cyberattacks. This growing challenge can be exacerbated as employees increasingly expect to be able to connect to work environments from anywhere, including from home, while traveling, and at the office. Securing the connection between employee devices and company resources should be an essential part of any organization’s security strategy.
