Copied from Zimbra.com

Zimbra’s Barry de Graaff and Randy Leiker from Skyway Networks team up for a new webinar series focused on Email Security. These hands-on webinars will include practical how-to information and best practices to help you maximize Zimbra. Learn how to fine-tune key security standards like SPF, DKIM, DMARC, MTA-STS, TLS, DNSSEC, DANE and TLSA to create a nearly unbreakable chain of trust from email sender to email recipient, ensuring maximum integrity and confidentiality. The webinars will include best practices and how to avoid common roll-out pitfalls for each security standard. This third webinar focuses on MTA-STS, TLS-RPT, and BIMI.

Zimbra with on premise Single Sign-On using Keycloak

In this article you will learn how to install Keycloak and how to set-up Zimbra on Keycloak. Keycloak is an open source identity and access management solution developed by RedHat.

By using Keycloak you will be able to manage all your users from Keycloak and implement Single Sign-On. Keycloak offers SAML, OpenID, social login, multi-factor authentication and more.

The technology used in this article is SAML, an open standard for Single Sign-On. When using SAML an Identity Provider (IdP) will take care of user authentication after which users can use their applications without having to log-on to each of them separately. In SAML these applications are called Service Providers (SP).

Learning objectives:

  • How-to Install Keycloak on Ubuntu 20.

  • Understand that Keycloak is a SAML IdP out of the box.

  • Configuring Zimbra as a SAML SP on Keycloak.

Using Zimbra with strong TLS configuration

Transport Layer Security (TLS) encrypts data sent over the Internet to ensure that eavesdroppers and hackers are unable to see what you transmit which is particularly useful for private and sensitive information such as passwords, credit card numbers, and personal correspondence. (further reading: https://www.internetsociety.org/deploy360/tls/basics)

In this article you will learn how to configure Zimbra to use only strong encryption ciphers for TLS.
