IronJump: The Hardened, Bash-Only Bastion Framework for Zero-Trust Control
IronJump is a hardened SSH bastion and endpoint management framework written in Bash. It enables security professionals and administrators to securely deploy and maintain jump servers and endpoint devices across hybrid infrastructure including IT, OT, and remote systems, without relying on cloud-based access brokers or third-party dependencies. IronJump enforces strict access controls, simplifies SSH key management, and includes automated tooling to harden services, manage users, and facilitate secure reverse tunnels with autossh. It was built for environments that demand high trust, minimal overhead, and full operational control.
Why IronJump Matters
Many organizations struggle to balance ease of access with strong security controls across distributed infrastructure. Traditional jump hosts are often misconfigured, overly permissive, or lack standardized deployment and management. IronJump solves this by offering a unified, role-driven management interface to handle both server and endpoint provisioning, all through a self-contained, auditable Bash framework.
IronJump reduces administrative complexity while increasing visibility, auditability, and control.
Who Should Use This?
- Penetration testers setting up isolated, disposable bastions during engagements
- Security teams managing remote access to sensitive IT/OT networks
- DevOps engineers deploying SSH access for on-prem or hybrid systems
- Red teams managing access tiers and backhaul tunnels to compromised infrastructure
- Sysadmins replacing brittle, undocumented bastion setups with hardened automation
Example Use Cases
- Secure Field Device Access: Grant engineers temporary access to remote OT devices through a hardened central jump host with SSH key expiration.
- Penetration Test Infrastructure: Deploy a temporary SSH bastion during an internal assessment to route traffic securely through controlled tunnels.
- Reverse Tunnel Access for Remote Linux Hosts: Connect untrusted or roaming devices back to a central IronJump bastion for secure remote access.
- Tiered Administrator Management: Assign unique SSH keys and expiration dates to different admin levels across critical endpoints.
- Incident Response Containment: Rapidly deploy IronJump to isolate compromised hosts while maintaining controlled access for forensics.
