Users --- ## User Control option | description ---- | ---- `require_login` | Prevent anonymous access. `show_welcome_with_login` | Show welcome page next to login page. `allow_user_creation` | Allow user registration. When False, admins must create users; often coupled with `require_login`. `allow_user_dataset_purge` | Users can purge (permanently delete) their datasets. `api_allow_run_as` | List of email addresses of API users who can make calls on behalf of other users. `expose_dataset_path` | Users to see the full path of datasets via the "View Details" option in the history. .footnote[.center[options in `galaxy.yml`]] ??? - These options let you control user login. - For example, are anonymous users permitted? - Are users able to register themselves? - Are users able to purge datasets themselves? - All of these are questions you will need to consider. - The API allow run as option can be useful if you have an external system submitting jobs to Galaxy on behalf of your users. --- ## User Activation Require verification that a user's email is real. You must enable SMTP first. option | description ---- | ---- `user_activation_on` | Require users to click link in email before running jobs. `activation_grace_period` | Time (hours) that a user can 'explore' Galaxy before activation lockout. `inactivity_box_content` | Message provided to non-activated users. `email_domain_blocklist_file` | Defines domains in XXX.YYY format that will be rejected as user emails. .footnote[.center[options in `galaxy.yml`]] ??? - Whenever a user registers, user activation settings control how this process happens - If you want to require activation they cannot run tools until they receive the confirmation email - If you want to prevent users registering from specific domains --- ## Admin Control option | description ---- | ---- `admin_users` | Comma-separated list of admin users' emails. `allow_user_deletion` | Admins can delete users. `allow_user_impersonation` | Admins can become other users. Great for debugging / user assistance. `bootstrap_admin_api_key` | Admin super-key allows many API admin actions without having a real admin user. .footnote[.center[options in `galaxy.yml`]] ??? - In the ansible galaxy training, you set the admin_users variable to define an admin email - User impersonation is a very commonly used feature - It allows admins to debug issues in their users' histories - A bootstrap api key cannot be used for every task an admin API key can be used for - This is because it is not tied to an individual user --- ## User Privacy option | description ---- | ---- `expose_user_name` | Users can view other registered usernames. `expose_user_email` | Users can view other registered emails. `new_user_dataset_access_role_default_private` | Newly created datasets are private to the creating user. .footnote[.center[options in `galaxy.yml`]] ??? - These options control if the username or email are shown as a dropdown in the sharing menus - The option "new user dataset access role default private" is important - By default when users share by link, all datasets are public - When you set this option, datasets are private, even though the history is shared via link - Users will complain when it doesn't work, and have to be educated to click the appropriate buttons --- # Roles and Groups ??? Roles and Groups --- ### Role Based Access Control (RBAC) **Admin** can: * create roles (each user automatically has their own 'private' role) * create groups * assign roles to groups * assign users to groups * assign groups to roles * assign users to roles * assign permission sets to roles * assign permission sets to groups ??? - Galaxy uses RBAC for permissions in many places - Roles can be created, and assigned permissions - Roles and groups behave similarly, grouping users together and granting permissions --- ## Dataset Roles .left-column50[ **manage permissions** * Users who have associated role on a dataset can manage the roles associated it. **access** * Users having associated role can use/view/download a dataset for analysis. Users must have every role associated with a dataset in order to access it **new_user_dataset_access_role_default_private** (`galaxy.yml`) * When this is set, datasets are private by default. ] .right-column50[.middle[.image-90[ ![User_roles](../../images/dataset_roles.png) ]]] ??? - The manage permission controls which accounts can manage permissions of datasets - Access permission is those who can see and work with the data - These can be controlled in the permissions menu of datasets - Or more generally at the history level - Users must have every role listed in order to access that dataset - This leads to the odd case where users wish to share with multiple groups - But by adding more roles, it becomes unavailable to everyone --- ## Library Roles .left-column50[ * **access library**: Restrict access to this library to only users having associated role * **manage library permissions**: Users having associated role can manage roles associated with permissions on this library item * **add library item**: Users having associated role can add library items to this library item * **modify library item**: Users having associated role can modify this library item ] .left-column50[.image-90[ ![Library_roles](../../images/Library_roles.png) ]] ??? - Access library permits users with any of the listed roles to access the library - No roles means a public library - Generally the last three are set to the same values, unless you have complicated requirements - In the library management, someone with any subset of the roles listed may make changes - This is very different from dataset permission management, where users must have every role --- # Quotas ??? Quotas --- ## Quotas Used to control user disk usage. option | description ---- | ---- `enable_quotas` | Enable enforcement of quotas. Quotas can be set from the Admin interface (under Data). Must create quotas in admin interface before any quota will be enforced, otherwise 'unlimited' Amounts: - Examples: "10000MB", "99 gb", "0.2T", "unlimited" - = / + / - Default for user class: - None (No) - Unregistered Users - Registered Users or associated with Groups or Users .footnote[.center[options in `galaxy.yml`]] ??? - You can enable quotas in your galaxy.yml file - When the user has more data than their quotum permits, they are prevented from starting new jobs. - many sites setup a "quote increase request" form, to let users request increases for specific, temporary projects --- class: left ## Quota Details - Quotas can be set for Users, or all users of a Group - But it is not a "group quota" - The quota is applied to individual users Storage - Quotas are stored in the DB tables `galaxy_user`, `galaxy_group`, and `quota` ??? - Quotas can be set for Users or Groups - But it is applied individually, as users may receive multiple quota changes - E.g. a user working for two groups, might receive two different quota increases --- ## Quota Automation - There is currently no quota automation. - Some individuals have written their own quota automation but it is quite ugly ([usegalaxy-eu/quota-sync](https://github.com/usegalaxy-eu/quota-sync)) - Could be nicer with a lot of work - Quotas are like group/user management: not managed by files, only within UI/API ??? - Quotas can be managed through the API - Some people want to automate this process, but it needs more work. --- # Authentication Systems ??? Authentication Systems --- ## LDAP / AD - Galaxy can be configured to use LDAP or Active Directory for authentication - There is a config file named `config/auth_conf.xml` - User login then triggers an LDAP search for the user - (optional) Galaxy binds with some bind credentials - Searches for the user DN - Re-binds with the user DN and password - If the user is found, they are logged in ??? - LDAP and Active Directory can be used as an authentication method - This is done through the auth_conf.xml file - When the user logs in, the LDAP server is queried for the user --- ## Shibboleth, CAS - Many alternative authentication systems are widely used at universities and organisations - Galaxy itself does not natively support these systems - However, you can use a proxy to authenticate users - nginx and apache have modules for both of these methods ??? - Shibboleth and CAS are commonly used at some universities - While Galaxy does not natively support these, you can use a proxy to authenticate users - Nginx and apache both support this --- ## OIDC - Galaxy can be configured to use OpenID Connect for authentication - There are two configuration files: - `config/oidc_backends_config.xml` - `config/oidc_config.xml` - Supports a variety of providers: - Google - Custos - Globus - ORCID - LS Login (Elixir AAI) - KeyCloack ??? - OIDC is a common authentication method - There are two configuration files required for this - Galaxy supports a variety of providers - OIDC means you as an administrator don't have to worry about validating the account, or storing passwords --- ## Built in Authentication - Galaxy has it's own authentication system - Enabled by default option | description ---- | ---- `password_expiration_period` | Days before requiring a user to change password. ([NIST recommends not requiring password changes.](https://en.wikipedia.org/wiki/Password_policy#NIST_guidelines)) `session_duration` | Minutes before invaliding a user's session, requiring re-login. .footnote[.center[options in `galaxy.yml`]] ??? - Galaxy has it's own authentication system - There are some options are related to IT security policies - Check with your local IT authority for best practices for your organisation - Please consider not setting a password expiration period, as NIST recommends against it --- ## Others (`REMOTE_USER`) - For all other authentication systems - If your authentication system provides a username in some secure way to the webserver - Then you can use it to authenticate users - The webserver must set the `REMOTE_USER` header - Galaxy will **trust** this header ??? - If you use a different authentication system than one previously mentioned - and your users are authenticated in some manner through your webserver/proxy - Then you can take advantage of `REMOTE_USER` authentication - It is a very simple authentication method, the webserver sets a header, and galaxy implicitly trusts it. --- ### Remote User (Security) - If you have local users on the Galaxy head node - Then please set `remote_user_secret` - This will send an additional secret header to Galaxy that will be validated - Otherwise local users can `curl` your Galaxy server, and impersonate any user. ??? - An important aspect for security is that if you have local users on the Galaxy head node - Then you should set the `remote_user_secret` option, to prevent them impersonating other users --- ### <i class="fas fa-key" aria-hidden="true"></i><span class="visually-hidden">keypoints</span> Key points - Galaxy has a powerful user and group managment system that can be utilized for Quota management. --- ## Thank You!
