GeoServer Hardening for DoD and Federal Environments
Most GeoServer instances we look at in government environments are running a lot closer to the default install than anyone realizes. GeoServer is solid software. Its defaults are built to get a map on the screen fast, not to pass an ATO.
Hardening closes that gap. We take the instance you have, find what's exposed, fix it, and hand back a documented, STIG-aligned deployment your ISSM can sign off on.
What we usually find
- The admin account still works with the default password. GeoServer ships with admin / geoserver, and it survives into production more often than you'd think.
- The web admin console is reachable from the same network as the map services.
- Demo workspaces and sample layers are still published.
- WFS-T is turned on even though nobody writes data through the service.
- The version is behind. CVE-2024-36401 is the one everyone should know: a remote code execution flaw in how GeoServer evaluated property names in OGC requests. It was patched in mid 2024 and added to CISA's Known Exploited Vulnerabilities list. If your instance was a few releases behind, anyone who could reach it could run code on the server.
- Full stack traces come back to the client on errors, which tells an attacker exactly what's running underneath.
- The servlet container runs as root with write access to the entire data directory.
What the engagement delivers
- GeoServer configuration aligned to the DISA Application Security and Development STIG
- JVM and container settings tuned for your mission workload
- TLS everywhere, with authentication wired into what you already run: CAC/PKI, LDAP, or Keycloak over OpenID Connect
- Layer and service level access rules, so users only see what they're cleared to see
- An automated vulnerability scanning pipeline with remediation tracking, so the next CVE doesn't depend on someone reading a mailing list
- A hardened deployment package with documentation and compliance artifacts: SBOM, vulnerability report, and a system administrator guide
How it runs
Week one is discovery. Version, extensions, data directory, network exposure, authentication. You get a findings list ranked by severity before we change anything.
The middle of the engagement is remediation, done in staging first and promoted once your team has seen it work.
The last week is handoff. Documentation, artifacts, and a walkthrough with your admins so they own the result.
Why we can do this fast
CoreSpatial Server is our own hardened GeoServer distribution, and it's been in production in DoD environments since 2016. Every quarterly release ships with an SBOM and a vulnerability advisory report, and High and Critical CVEs get patched right away. Our engineers are active in the GeoServer community, filing issues and answering questions on the project lists.
We've also built a custom FIPS-compliant keystore provider for GeoServer, which matters if your environment requires FIPS 140.
So we aren't learning GeoServer on your contract. This is the thing we do every day.
