User accounts in the intranet are assigned with SSH keys to access resources in the network or from its own subnet.Īdditionally, bastion hosts keep track of network activity to alert administrators of any suspicious activity. Only then will users gain access to an asset or application stored in the internal network. To authenticate user identity, the bastion host requires SSH keys. As all connections are filtered through the bastion host, business users are not exempt from establishing SSH connections. Administrators may grant access to an IP address whitelisted by the IT security team. Functions, ports, user accounts, protocols, and applications unrelated to SSH proxy services are promptly disabled.īastion hosts only provide access to SSH connections from internal IP addresses. As an SSH proxy server, the bastion host’s sole purpose is to approve or deny communication requests. Thus, a bastion host comes in handy to bridge the gap between the internal network and the public internet. Network administrators will have a hard time managing user traffic across all ports while maintaining asset security. When administrators and other users wish to access the intranet from an external network like the public internet, security risks like data loss and exposure are highly likely.įrom the IT perspective, allocating multiple communication ports for the external network is not only dangerous but also impractical. What is a Bastion Host?Ī bastion host is the entry point for systems and applications stored in a private network or intranet. The bastion host has seen its heyday, but how does it fare in the current demands of enterprise networking? As technology advances at lightning speed, are bastion hosts still reliable? In this article, we’ll discuss how a bastion host works, its security risks, and the online security alternatives to a bastion server. Bastion hosts may be modified to reinforce its security measures and keep external threats at bay. While elaborating on network firewalls, Ranum described that a bastion host is acritical structure, alongside firewalls, in upholding network security. Ranum first mentioned the idea of a bastion host. In an article from 1990, cybersecurity researcher Michael J. With the bastion host, the modern information age adopts the function of bastion forts to increase resistance against malicious attacks on computer systems. In the mid-16th to 19th centuries, forts replaced towers with flanked structures known as bastions to fortify defense against ranged attacks.
