Managing secure and controlled access to infrastructure is a critical piece of any organization's security strategy. Bastion hosts are the traditional solution, acting as a secure intermediary for access to sensitive systems. While effective, they come with notable challenges, including management complexity, elevated attack surfaces, and limited flexibility in modern distributed cloud environments.
An emerging approach eliminates the need for bastion hosts altogether by implementing more agile and robust break glass access procedures. This blog post explores a modern alternative to bastion hosts, outlines the benefits, and discusses how to adopt secure and auditable break glass access procedures in your environment.
Why Move Beyond Bastion Hosts?
Bastion hosts once served as the go-to solution for secure access, anchoring perimeter-based network security models. However, today's environments are highly dynamic, with workloads frequently shifting across hybrid or multi-cloud infrastructures. Bastion hosts present several shortcomings:
1. Operational Complexity
Organizations must maintain bastion hosts, including regular updates, secure configurations, and credentials management. This creates ongoing administrative overhead.
2. Security Risks
A compromised bastion host can become an entry point into your critical infrastructure. Overprivileged accounts and static credentials often worsen this risk.
3. Scalability Challenges
Modern cloud environments often host hundreds or thousands of nodes. Configuring and orchestrating access fo rthose nodes via bastion hosts doesn't scale seamlessly.
For engineering teams looking to implement faster, fine-grained, and zero-trust access mechanisms, the time is ripe for exploring alternatives.
What Are Break Glass Access Procedures?
Break glass access is an emergency access mechanism designed for highly controlled scenarios where traditional access mechanisms are restricted or unavailable. Instead of relying on a static entry point, like a bastion host, break glass access uses dynamic, time-bound permissions and auditing to minimize risk while enabling operational needs.
With the right tooling, modern break glass workflows offer:
- Ephemeral Credentials: Grant access for only the duration of an incident or task.
- Granular Permissions: Ensure access is limited to what’s absolutely necessary.
- Comprehensive Auditing: Track every request, approval, and action for compliance purposes.
Key Steps to Replace Bastion Hosts with Break Glass Access
Shifting to break glass access doesn’t need to disrupt your existing infrastructure. Here’s how to implement it:
1. Define Emergency Scenarios
Determine the scenarios that require break glass access, such as critical incidents, system outages, or compliance audits. Establish what types of resources need access and identify key personnel.
2. Set Up Role-Based Permissions
Ensure each request corresponds to predefined roles with limited scope. Avoid granting full admin access unless absolutely necessary.
3. Implement Ephemeral Access Tokens
Leverage tools that integrate with your authentication systems. Issue tokens that expire automatically, preventing misuse or excessive privileges.
4. Enforce Approval Workflows
Add approval steps for requesting emergency access. Line managers or specific reviewers should validate and approve each request.
5. Enable Full Visibility and Auditing
Record and log every access attempt, including user details, requested resources, and actions taken. Use these logs to maintain compliance and audit readiness.
Benefits of This Approach
Adopting break glass procedures as a bastion host alternative comes with several operational and security benefits:
- Reduced Attack Surface: Eliminates a centralized entry point into critical systems.
- Increased Agility: Access procedures can adapt to rapidly changing environments or configurations.
- Stronger Compliance: Audit logs make compliance with security frameworks straightforward.
