Managing secure access in complex environments is one of the most critical parts of infrastructure design. Traditional bastion hosts are often the go-to method for this, acting as a controlled gateway for privileged access to sensitive systems. However, the operational burden, maintenance costs, and security challenges tied to bastion hosts can outweigh their benefits. Fortunately, modern approaches are replacing bastion hosts as part of evolving access control best practices. This post will focus on designing and operationalizing break glass access procedures without relying on a traditional bastion host.
What is Break Glass Access, and Why is it Important?
Break glass access refers to an emergency access mechanism that allows privileged entry to systems under special circumstances when standard authentication workflows fail. Instead of everyday operations, break glass procedures are typically reserved for extreme cases such as system outages, revoked credentials, or critical incident troubleshooting.
This kind of access must balance security and control to prevent misuse or unauthorized escalation. For years, bastion hosts have served as an integral part of such procedures, but with improved toolchains and decentralized access systems available today, it's now possible to eliminate bastion hosts from the equation entirely.
Issues with Bastion Hosts in Break Glass Scenarios
While bastion hosts might seem like an effective middleman for controlled access, they introduce several challenges:
1. Security Risks
A bastion host is a single point of access, making it an attractive target for attackers. Efforts to safeguard the host through hardening and restricting IP-based access help, but they don’t eliminate the risk of credential theft or misuse. Often, attackers winning control of a bastion host enables lateral movement.
2. Maintenance and Configuration Overhead
Deploying and managing bastion hosts at scale requires patching, monitoring, logging, and configuration updates. Keeping the infrastructure aligned with security compliance standards like SOC 2 or ISO27001 can be a massive drain on operational teams.
3. Poor Scaling
In environments with microservices or dynamic cloud workloads, managing bastion host configurations to meet dynamic access needs leads to friction, errors, or delays.
4. Incident Response Bottlenecks
Under high-pressure incident conditions, enforcing time-limited, one-time access via a bastion adds unnecessary steps that slow resolution times.
The better approach is to eliminate dependency on bastion hosts entirely while retaining rigorous control standards.
How to Replace Bastion Host-Dependent Break Glass Access
A modern bastion-less break glass approach employs identity-based access management, automation, and auditability baked into workflows. Here's how you can design an effective bastion host replacement strategy:
Step 1: Leverage Identity Providers for Authentication
Start by integrating your infrastructure with an Identity Provider (IdP) like Okta, Azure AD, or Google. Unlike static credentials stored centrally, IdPs enforce strong authentication methods, including MFA, tying access to verified user identities. For break glass scenarios, create clearly defined (and default-disallowed) privileged roles that can be activated ad hoc through the IdP.
Step 2: Use Temporary Access Creds with Fine-Grained Policies
Instead of providing long-term access keys, generate temporary credentials through services like AWS IAM, Azure Active Directory, or GCP IAM. Temporary credentials decrease the risk window by expiring in minutes or hours. Define fine-grained policies, ensuring minimal permissions are issued for break glass events.
Step 3: Automate Role Escalation Procedures
Design escalation workflows that trigger on pre-approved criteria. For example:
- A critical outage triggers a request within a system like a ticketing platform (e.g., Jira).
- Approval flows route through security managers using multi-stage workflows for signoffs.
- Once approved, automated systems generate credentials automatically—with all logs and approvals captured for audit.
Step 4: Audit and Logging
Sophisticated monitoring and logging solutions like Elastic, Splunk, or Datadog guardrails the break glass procedure by ensuring transparency. Every event, from access requests to role activations and file downloads, is captured in immutable logs. This enables post-mortem reviews for security and adherence to internal guidelines and compliance requirements.
Step 5: Ensure Emergency CLI and API Access
For DevOps environments that rely on CLIs or automated scripts (e.g., Terraform/Pulumi), implement token-based API access that honors the same layered permissions applied to GUI break glass operations.
By tying emergency access to identity and role-based permissions systems, and automating credential generation and expiration, you’ve successfully transitioned away from dependent bastion infrastructure.
Advantages of Bastion Host Replacement for Break Glass Access
Switching to this bastion-less workflow provides tangible benefits for your team:
- Improved Security: Identity-based systems eliminate static keys or credentials tied to a single server.
- Time-Saving Access Requests: Fast, automated workflows maintain productivity during incidents.
- Reduced Maintenance Costs: Eliminating a bastion reduces overhead from managing, patching, and scaling those services.
- Incident Response Scalability: Distributed systems simplify access workflows vs focusing bottlenecks on bastion hosts.
