Patch Management isn’t the only issue to tackle.

Furthermore, I want to avoid breaking the service and minimize the outage each time an update is deployed. Next, I want my OS to be updated quickly after a patch is released.

I also want to be up-to-date with the most recent innovations and best practices on this theme. Local copies are the hardest to protect and therefore to trust.īonus: I like when I can replay the logs (using script command for example) OS hardening and Patch Managementīecause my bastion is a critical resource in my infrastructure, I want a state-of-the-art OS hardening on my bastion.

Prefer remote storage for the logs because you could more easily control access and restrict the permissions.

Immutability of the logs: my logs can’t be overwritten and changed.

access control to the log because they are confidential AND can contain a lot of secret information (input secret, secret displayed from configuration files, etc.).

what (session logs): both input and output (take attention to secret information inside the logs).

where: source of the connection, and the destination of the connection.

I classified my needs into four categories: There are two parts in a logging capability. Logs are the second key feature for an SSH Bastion.

removing access of a compromised account.

removing access to an employee because you have a social issue (there is a risk for your organization).

Quickly removing access is a key feature for a lot of use cases: You need to take this into account.Ībility to quickly revoke access (usually provided by the SSO integration, but some systems aren’t synchronized, so your Bastion has to do the job instead). ℹ️ Note: this integration could lead to external dependency and could have an impact in case of an incident (one on the SSO can’t prevent you from connecting to your infrastructure).

I can define most of my ACL in my SSO to centralize the information (shared use with other tools).

The system should be connected to my organization SSO (with OIDC or SAML):

where (from/to): I can control the source and the destination of the connection.

when: allows me to set a time range for user or group.

who: control who can access the bastion.

I classified my needs with these three categories: Authentication, user management, and user permissionsįined-grained access control is the primary feature I’m looking for when I evaluate an SSH Bastion.

This list comes from many years of managing SSH Bastions and also a lot of security audits from third parties. I’m sharing with you what I expect from this type of service and what features I want to have.

When you are using SSH in a corporate environment, in order to comply with security standards like ISO 27001, PCI DSS, or SOC2, you need an SSH Bastion to manage remote access to your infrastructure. SSH is the de facto standard for remote access to your GNU/Linux operating system (and for all modern Unix systems).
