Managing and securing access to cloud infrastructure is a core responsibility for modern engineering teams. Traditional bastion hosts have been the go-to tool for controlling and auditing access to sensitive environments. However, they introduce operational complexity, maintenance overhead, and potential scalability issues. With advancements in audit logging and cloud-native practices, there’s now a better way to achieve secure access with detailed audit logs—without the baggage of bastion hosts.
What Are Bastion Hosts and Why Replace Them?
A bastion host is a single-purpose server designed to control access to a private network. Typically, teams use bastion hosts as an intermediate hop for SSH or RDP connections to production infrastructure. While effective at restricting access, bastion hosts are not without trade-offs:
- Operational Overhead: They require configuration, monitoring, and updates to stay in sync with your security practices.
- Limited Audit Tools: Some bastion host setups rely on manually configured logging to track activities.
- Scalability Issues: As teams and environments grow, managing access through a bastion host becomes increasingly complex.
- No Built-in Identity Context: Logging is often tied to IP addresses, not specific users, making it harder to identify who did what.
Instead of relying on traditional bastion hosts, modern solutions emphasize using native audit logs directly from cloud providers or access systems. By replacing the bastion host layer, you can simplify workflows and improve visibility into access events.
Why Audit Logs Are the Future of Access Management
Audit logs provide a comprehensive view of what happens in your environments. Managed well, they eliminate the need for intermediary servers like bastion hosts. Here’s why:
1. Granular Event Tracking
Audit logs map every action to an individual user or system, ensuring clear accountability. Unlike bastion logs that provide basic SSH or RDP session logging, audit logs can capture detailed information like resource creation or configuration changes across your cloud environment.
2. Lower Maintenance Requirements
Cloud-based audit log systems operate without adding infrastructure to monitor or upgrade. There's no need to manage users at the bastion host level, sync SSH keys, or keep a server hardened and compliant.
3. Seamless Scale Across Teams and Regions
Audit logs operate at the cloud provider level, meaning you don’t need to account for regional complexity or user scaling independently. They enable consistent access policies no matter how large your teams grow.
4. Improved Security Posture
Replacing a bastion host reduces the attack surface. Audit logs are read-only by design and cannot accidentally allow access. This ensures logs cannot be tampered with and remain a reliable source of truth.
How to Transition Away From Bastion Hosts
Moving away from bastion hosts means adopting solutions that seamlessly track access and activities while enforcing strict security. Here’s a simple plan to get started:
- Enable Cloud Provider Audit Logs
The leading cloud providers—AWS, Azure, GCP—offer robust audit logging systems. Services like AWS CloudTrail, Azure Monitor, or Google Cloud Audit Logging capture access and configuration changes across your resources. - Implement Role-Based Access Control (RBAC)
Use IAM (Identity and Access Management) policies to restrict permissions at a fine-grained level. With RBAC, you eliminate the need for lengthy allow-lists or manual user management on bastion hosts. - Adopt Temporary Credential Systems
Replace static credentials or key-based access with time-limited credentials or identity federation systems. This minimizes the risk of credential misuse and ensures all access events are tied to specific identities. - Centralize Log Analysis
Integrate your audit logs with observability and incident response tools. Modern platforms enable quick searches and actionable insights into access behaviors without needing to dig into old bastion host logs. - Test and Verify Access Flow
Before fully deprecating bastion hosts, ensure your access policies and logging configurations provide equivalent levels of detail and control. Run simulations to confirm compliance and security requirements are met.
