This document provides and overview of how to imporove security for individuals or organizations running the IllumiDesk system using the software artifacts avaiable within this repository. IllumiDesk maintains additional security policies and practices documents which cover the hosted and enterprise versions of the system.

Like most systems, IllumiDesk depends on many dependencies to run the system. In particular, IllumiDesk relies on JupyterHub and the Tornado web server to work correctly. Please refer to the provided links to consider their own security recommendations.

1. TSL: use TSL for all internal and external services. This includes enforcing the use of TSL from clients located outside your network and services that need to communicate with each other within your private network. For example, this setup is not recommended, even though it requires TSL from public facing clients:

   Public Client --> Port 443 --> [Reverse Proxy] --> Port 80 --> [Backend] --> Port 80 --> [Notebooks]

A more secure setups would reflect end-to-end TSL:

Public Client --> Port 443 --> [Reverse Proxy] --> Port 443 --> [Backend] --> Port 443 --> [Notebooks]

2. Environment Variables: several environment variables contain sensitive information, such as database passwords. Never store raw credentials within docker images. When using an environment variables within a running container make sure you store the source of the environment variable value in a secure location and that the running container has the proper permissions to access the encrypted values.

3. Rotate Keys: rotate encryption keys whenever possible. For example, keys used to encrypt session cookies should be periodically rotated.

4. User Credentials: if you plan on using the system to store credentials from your users then it is recommended to use a trusted third party system to manage the user passwords. For example, you could use an integrated system such as a Learning Management System or a federated identity solution which use the standard OAuth features.

IllumiDesk automates security scanning and dependency upgrades throughout the software pipeline wherever possible. These automations include but are not limited to:

• Scan upstream dependencies for security vulnerabilities. If a security vulnerability is found and a patch is available from the upstream dependency, automatically create a Pull Request and alert the repository maintainers.

• Scan docker images after building and pushing the images to the registry.

• Block merges to the main branch which do not pass all tests and/or do not have the sign off from one of the project's maintainers.

• Ensure that all dependencies used for deployments are set to specific releases.

We release patches for security vulnerabilities. Which versions are eligible receiving such patches depend on the CVSS v3.1 Rating:

Please report (suspected) security vulnerabilities to security@illumidesk.com. You will receive a response from us within 48 hours. If the issue is confirmed, we will release a patch as soon as possible depending on complexity but historically within a few days.

If your disclosure is extremely sensitive, you may choose to encrypt your report using the key below. Please only use this for critical security reports.
