Introduction to single sign-on

Updated

Overview

Implementing single sign-on (SSO) in your Code42 environment provides security benefits and simplifies the sign-in experience. This article provides:

Considerations

External authentication systems
Our Technical Support Engineers can help with authentication issues caused by interaction with Code42 products. However, troubleshooting authentication issues outside your Code42 environment is beyond the scope of our Technical Support Engineers. For assistance with external authentication systems, contact your authentication vendor.
  • To use this functionality, you must be assigned the Identity Management Administrator role. 
  • Code42 usernames must match SSO usernames. How you accomplish this depends on how you deploy Code42 agents.
  • Code42 supports service provider-initiated SSO but does not support identity provider-initiated SSO. Therefore, users cannot sign in to your Code42 environment from the identity provider's website or application, but instead must log in using a browser bookmark. 
  • SSO provides user authentication but does not provide user management. Set up SCIM provisioning or use the Code42 console to manage users. 
  • Code42 does not support Single Logout (SLO). Users must sign out of the identity provider to end their single sign-on session.
  • The Code42 console expects SAML assertions to be signed. To configure Code42 to support advanced SAML request configurations, see Set SAML attributes for SSO. 

SAML 2.0 algorithms

The following SAML 2.0 algorithms are still allowed only when used in properties of the identity provider:

  • RSA/MD5 for digital signatures:
    SignatureConstants.ALGO_ID_SIGNATURE_NOT_RECOMMENDED_RSA_MD5
  • MD5 for HMAC:
    SignatureConstants.ALGO_ID_MAC_HMAC_NOT_RECOMMENDED_MD5

If your identity provider is up to date and configured appropriately, these deprecated methods are not provided. However, these deprecated algorithms are permitted if your identity provider still provides these methods for signing its tokens.

SSO configuration articles

You can configure SSO for Code42 with any provider that uses SAML 2.0. For general directions, see How to configure SSO in your Code42 environment.

The following articles provide instructions for specific providers.

Before you begin SSO configuration

Verify identity provider configuration
  • Make sure the SSL certificate of your SSO identity provider has been signed by a trusted Certificate Authority (CA).
  • Make sure you have administrative access to the identity provider or have contact with an identity provider administrator.
Verify network configuration
  • Configure your private network, Internet, and VPN settings to allow client devices to communicate with your identity provider on port 443. Test client connectivity to the identity provider before you proceed.
  • If you want to use URL-based metadata exchange to configure Code42 and the identity provider to work together, make sure two-way communication is available between them on TCP port 443. If two-way communication is not available or not allowed, you must download the identity provider's metadata file and make it accessible to Code42.
  • Confirm the required ports with your identity provider to determine if custom ports are being used.

What is SSO?

Single sign-on SSO is an authentication method that allows a user to use the same credentials to sign in to multiple applications. You can integrate Code42 with any provider that uses SAML 2.0. 

Definitions

SSO authentication process

When a user attempts to access an SSO-enabled protected resource, such as a Code42 application or Code42 console, the user is redirected to the identity provider. If the user still has an active session with the identity provider, the user is automatically redirected to the desired resource. If the user does not have an active session, the user is prompted to enter credentials. Once authenticated, the user has access for a configurable period of time to all resources protected by the identity provider.

The following diagram describes how the Code42 platform components and the SSO identity provider interact.

  • Service provider: Code42 cloud instance
  • User agent: Code42 applications or web browser
  • Identity provider: A SAML 2.0 identity provider that supports HTTP POST binding

Item Description
1

When a user attempts to sign in, the user agent sends a sign-in request to the service provider.
2 The service provider refers the user agent to the identity provider's SSO URL.
3 The user agent sends an authentication request to the identity provider.
4 The identity provider authenticates the user and provides the user agent with a SAML authentication token.
5 The user agent sends the authentication token to the service provider.
6 The service provider accepts the authentication token and grants the user access to the user agent.

SSO advantages, disadvantages, and limitations

Advantages
  • Delegates all authentication to the identity provider
  • Allows for centralized authentication in organizations that do not implement Active Directory or LDAP (for example, computers that are not tied to a directory)
  • Minimizes phishing opportunities
  • Provides detailed reporting on user access
  • Reduces user password fatigue from different username and password combinations
  • Reduces time spent re-entering passwords
  • Reduces IT costs due to lower number of IT help desk calls about passwords
Disadvantages
  • Prevents access to service providers if the identity provider is unavailable
    For this reason, SSO can be undesirable for systems requiring guaranteed access at all times, such as security or plant-floor systems.
  • Allows an unauthorized user to gain access to all protected resources if a user's credentials are compromised
    To reduce risk, ensure that credentials are stored securely, and consider implementing strong authentication methods such as smart-cards and one-time password tokens.
  • Provides user authentication but does not provide user management
    User management is provided by the local Code42 directory, SCIM provisioning, or Code42 User Directory Sync.
Code42 limitations
  • Code42 does not handle single sign-off. If a user logs out of the Code42 environment, the Code42 cloud does not notify other service providers, and vice-versa.
  • When a user signs out of the SSO identity provider, he or she is not automatically signed out of the Code42 applications. There are two ways the user can be signed out of the Code42 applications:
    • An administrator can deauthorize the user's devices from the Code42 console.
    • The user can sign out of the Code42 applications.
