# Security Notes
## Sensitive Files
- `.env` — Contains your Tailscale/Headscale auth key and service configuration. **Never commit this file.**
- `tailscale/tailscale-data/` — Contains Tailscale node state and keys. **Never commit this directory.**
## Capabilities
This compose file adds the following capabilities to the Tailscale sidecar:
- `net_admin` — Required for Tailscale to manage network interfaces and routes.
These capabilities are necessary for Tailscale to function but increase the attack surface if the container is compromised.
## Recommendations
- Use a dedicated, limited-scope auth key for each service.
- Regularly rotate auth keys.
- Review Headscale/Tailscale ACLs to ensure services only have the access they need.
- Keep the Tailscale Docker image reasonably up to date.
## Default Passwords
The `docker-compose.yml` file contains placeholder values (`***`) for sensitive items such as:
- Postgres password
- Vikunja JWT secret
**Change these values** before deploying anywhere security matters. Never use the default placeholders in production or shared environments.
