FIPS 140-3 Certification

This image is FIPS-validated to ensure its cryptographic operations meet the Federal Information Processing Standards (FIPS) required for secure government and regulated environments. Its core cryptographic modules are validated under the NIST Cryptographic Module Validation Program (CMVP) and comply with the FIPS 140-3 standard.

To verify that the FIPS 140-3 provider is configured and active, follow the instructions in the FIPS compliance tab.

Try It Out

Guacamole needs two companion pieces to run: Guacamole-Server, which provides guacd, the daemon that proxies RDP, VNC, and SSH connections, and a database that stores users and connections through Guacamole's JDBC auth extension. The steps below start Guacamole-Server-FIPS, a Postgres-FIPS database, and the Guacamole web application, all using Minimus FIPS images.

docker network create guacamole-net

docker run --rm -d --name guacamole-server \
  --network guacamole-net \
  reg.mini.dev/guacamole-server-fips

docker run --rm -d --name postgres \
  --network guacamole-net \
  -e POSTGRES_DB=guacamole_db \
  -e POSTGRES_USER=guacamole_user \
  -e POSTGRES_PASSWORD=MinimusSecure!! \
  reg.mini.dev/postgres-fips

docker run --rm reg.mini.dev/guacamole-fips /opt/guacamole/bin/initdb.sh --postgresql | \
  docker exec -i postgres psql -U guacamole_user -d guacamole_db -f -

If you see a connection error, give Postgres a few seconds to finish starting up and run the command again.

docker run --rm -d --name guacamole \
  --network guacamole-net \
  -p 8080:8080 \
  -e GUACD_HOSTNAME=guacamole-server \
  -e POSTGRES_HOSTNAME=postgres \
  -e POSTGRES_DATABASE=guacamole_db \
  -e POSTGRES_USER=guacamole_user \
  -e POSTGRES_PASSWORD=MinimusSecure!! \
  reg.mini.dev/guacamole-fips

Visit http://localhost:8080/guacamole/ to access the Guacamole UI and log in with the default administrator account:

• Username: guacadmin
• Password: guacadmin

This account is a well-known default, so change its password immediately after logging in.

TOKEN=$(curl -s -d "username=guacadmin&password=guacadmin" \
  http://localhost:8080/guacamole/api/tokens | sed -n 's/.*"authToken":"\([^"]*\)".*/\1/p')

Then create a connection with that token:

curl -s -X POST "http://localhost:8080/guacamole/api/session/data/postgresql/connections?token=$TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "demo-vnc",
    "protocol": "vnc",
    "parameters": {"hostname": "guacamole-server", "port": "5900"},
    "attributes": {}
  }'

Refresh the dashboard and demo-vnc will appear under "All Connections." (Nothing is actually listening on that host and port, so opening the connection won't succeed).

docker rm -f guacamole postgres guacamole-server
docker network rm guacamole-net

Technical Considerations

The Guacamole-FIPS image provided by Minimus is a FIPS-validated, slim, security-hardened alternative to the public image.

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

• See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
• Review the compliance report to see the default hardening and security configurations for the image.
