Single Sign-On

Glasswall Halo can be configured to enable Single Sign-On (SSO) with OpenID Connect (OIDC).

SSO is an authentication method that allows users to sign in using one set of credentials to multiple independent software systems. Using SSO means a user doesn't have to sign in to every application they use.

Below is the information on how to configure SSO within your Glasswall Halo solution using Microsoft Entra ID as the identity and access management (IAM) provider.

In principle, any IAM that offers OIDC may be configured to support SSO for Glasswall Halo.

Prerequisites for Microsoft Entra ID integration

• A Microsoft Enterprise Agreement for a Microsoft Entra ID account is required to enable this SSO option.
• A domain name must be configured for the Halo portal (Portal Service) to use SSO authentication.
• Azure App registrations are required whenever SSO authentication using Microsoft Entra ID needs to be enabled.
• There are three App registrations that need to be created:
  • cdrplatform-api-access
  • cdrplatform-portal-access
  • cdrplatform-portal-client
• The attached shell script helps to create these three app registrations. Enter the domain name you would like to use for the Portal as an argument to the shell script. For example, use halo.glasswall.com as the domain name and run the script:

bash create-azure-app-registrations.sh halo.glasswall.com

Configuration

Enable Microsoft Entra ID API authentication

To enable Microsoft Entra ID based authentication, set configuration.AuthenticationScheme=Bearer. Also set tenant_id and domain_name variables while deploying the Helm chart.

tenant_id=""
domain_name=""
helm upgrade --install cdrplatform-api-access cdrplatform-api-access --wait --atomic \
  --set image.tag="83174" \
  --set image.repository="glasswallhub.azurecr.io/cdrplatform-api-access" \
  --set ingress.tls.enabled=true \
  --set ingress.tls.domain=${domain_name} \
  --set ingress.tls.secretName=tls-secret \
  --set configuration.AuthenticationScheme="Bearer" \
  --set configuration.Authentication__Schemes__Bearer__ValidAudiences__0=api://cdrplatform-api-access \
  --set configuration.Authentication__Schemes__Bearer__ValidIssuer=https://sts.windows.net/${tenant_id}/ \
  --set configuration.Authentication__Schemes__Bearer__Authority=https://login.microsoftonline.com/${tenant_id}/v2.0/

Configure SSO login for the Glasswall Halo portal

• Set portal_domain, portal_client_id, tenant_id variables in the commands below and run them. The portal_domain is the domain name used to setup TLS for the portal service as well as the same domain used in the cdrplatform-portal-client app registration.
• portal_client_id is the Application (client) ID of the cdrplatform-portal-client app registration created in the prerequisites step.
• tenant_id is of the tenant where App registrations are created.
• enabled_pages variable should be set to PolicySettings when Policy API is deployed, otherwise set it to empty enabled_pages="".

portal_domain=""
portal_client_id=""
tenant_id=""
enabled_pages="PolicySettings"
helm upgrade --install cdrplatform-portal cdrplatform-portal \
  --set image.repository=glasswallhub.azurecr.io/cdrplatform-portal \
  --set image.tag=83310 \
  --set ingress.tls.enabled=true \
  --set ingress.tls.domain=${portal_domain} \
  --set ingress.tls.secretName=tls-secret \
  --set configuration.BackendUrl="https://${portal_domain}" \
  --set configuration.EnabledPages=${enabled_pages} \
  --set configuration.OIDC.ProviderOptions.Authority="https://login.microsoftonline.com/${tenant_id}/v2.0" \
  --set configuration.OIDC.ProviderOptions.RedirectUri="https://${portal_domain}/authentication/login-callback" \
  --set configuration.OIDC.ProviderOptions.ClientId="${portal_client_id}" \
  --set configuration.OIDC.ProviderOptions.PostLogoutRedirectUri="https://${portal_domain}/authentication/logout-callback" \
  --atomic

Next, the Portal Access service needs to enable SSO authentication using Microsoft Entra ID.

• Set tenant_id and portal_domain variables in the commands below and run them.

tenant_id=""
portal_domain=""
helm upgrade --install cdrplatform-portal-access cdrplatform-portal-access \
 --set image.repository=glasswallhub.azurecr.io/cdrplatform-portal-access \
 --set image.tag=83191 \
 --set ingress.tls.enabled=true \
 --set ingress.tls.domain=${portal_domain} \
 --set ingress.tls.secretName=tls-secret \
 --set configuration.AuthenticationScheme=Bearer \
 --set configuration.Authentication__Schemes__Bearer__ValidAudiences__0=api://cdrplatform-portal-access \
 --set configuration.Authentication__Schemes__Bearer__ValidIssuer=https://sts.windows.net/${tenant_id}/ \
 --set configuration.Authentication__Schemes__Bearer__Authority=https://login.microsoftonline.com/${tenant_id}/v2.0/ \
 --atomic
