Bastion Host (Jump Server)

Category: infrastructure

A specialized, hardened gateway node that provides secure access to a private server cluster from the internet.

A bastion host is the only point of ingress for your sovereign cluster. It requires multi-factor SSH key authentication and maintains aggressive firewall rules. All administrative traffic passes through this hardened jump server, shielding the internal multi-node cluster from direct brute-force exposure.

Common Examples

• We configured the avoca-engine-1 bastion host with mandatory SSH certificate rotation to ensure zero-trust access to our private node cluster.
• The bastion host logs every single command executed by administrators, providing a full audit trail for our sovereign infrastructure security compliance.
