Overview

ONOS CLI, GUI and REST API are all presently secured by allowing only authenticated access. 

  • ONOS CLI uses public/private key authentication
  • ONOS GUI uses form-based login
  • ONOS REST API uses basic authentication

All of these are backed by the existing Apache Karaf JAAS authentication realm, which by default allows key-based or user/password-based authentication configured in the etc/users.properties and etc/keys.properties files.

Presently, ONOS does not support differentiated role-based authorization. That may be added later.

Configuration

Without any configuration steps, ONOS CLI will continue to be accessible using the Apache Karaf client and the GUI & REST API will be accessible using both the built-in Apache Karaf credentials (karaf/karaf) and ONOS credentials (onos/rocks).

To enable the secure access, a new tool onos-secure-ssh has been provided. This tool will secure the ONOS CLI so it is no longer accessible using the Apache Karaf client; this client is inherently insecure as it relies on a well-known private key (yes that is an oxymoron). After running the onos-secure-ssh tool, ONOS CLI will be only accessible using direct ssh. The tool also deletes the default users and keys, and allows the user to specify their own user/password combination as follows:

$ onos-secure-ssh -u onos -p totallyRocks

The tool comes in two variants to support run-time deployments and dev-time usage. The dev-time variant secures the entire ONOS test cell with one invocation and will use the dev bench user’s public key to enable secure ssh CLI. The run-time variant secures just the instance on which it is invoked and uses the invoking user’s public key to enable secure ssh CLI.

Authentication

Since ONOS CLI is secured via key-based authentication, there is no explicit action required once the onos-secure-ssh tool was used.

Specifying login credentials for REST API will vary depending on the REST client. With curl, it would look something like this:

$ curl http://10.128.11.1:8181/onos/v1/devices --user onos:totallyRocks

The GUI login is very straightforward as it will automatically redirect to the login page, which looks like this:

The login will remain active while the browser is active or until user logs-out by clicking on the logout link in the right-hand side of the GUI mast-head. Presently there are no cookies and no mechanism to maintain authentication past browser restart. This may be added in future releases as we add token-based authentication.

HTTPS & Redirect

By default HTTPS is not enabled, but it can be easily configured and used directly, by modifying the etc/org.ops4j.pax.web.cfg file. The reason for this is that it requires a setup of keystore & truststore and unless one has a key signed by a CA, the self-signed key ends up raising issues with REST API and puts up entry barriers in the browser. For these reason, this remain a manual configuration task; see instructions in https://ops4j1.jira.com/wiki/display/paxweb/SSL+Configuration.

For the same reasons, neither REST API nor GUI will presently insist on communicating via HTTPS via mandatory redirect to a confidential channel. However, one can force HTTPS-only communication by disabling the HTTP channel by modifying the etc/org.ops4j.pax.web.cfg file.  Default version of this file is under source-control in tools/package/etc directory and is included in the corresponding distributable tar.gz, zip, deb & rpm packages.
