New Zimbra Webinar Series: Email Security

Post by rleiker »

Hi Everyone,

On Tuesday, March 8th, a new Zimbra webinar series kicks off. The multi-part webinar series provides a practical, hands-on approach to deploying a number of key email security standards including:
  • SPF & DKIM
  • DMARC
  • MTA-STS & TLS-RPT
  • DNSSEC
  • TLS & DANE
Deploying all of these standards will greatly increase the success of your email deliveries to recipients, but also secures your Zimbra users against a range of exploits from phishing, man-in-the-middle attacks, spoofing, and security downgrade attacks, just to name a few. If you have found deploying any of these standards in the past to be difficult or confusing, or have not yet deployed all of these standards and want a better understanding of what they do & why you should use them, this webinar series is tailor-made just for you. We hope you can join us for this informative & educational webinar series!

John us for the first episode in this series by registering here.

Just a reminder that the first episode in the new email security webinar series starts tomorrow, on Tuesday, March 8th. Tomorrow's topics will be SPF and DKIM.

If you have not yet deployed both SPF and DKIM, this webinar will be the helpful jump start you need to begin. Or, if you have deployed one or both of these standards previously, the discussion will include a number of best practice tips, including several that may not be readily obvious, to ensure you are getting the most out of your SPF and DKIM deployment.

On Tuesday, April 5th, the second episode in the Zimbra Email Security webinar series will premiere. This episode will be an in-depth discussion of how to deploy the DMARC standard for your Zimbra server.

Join us for the second episode by registering here.

You will learn about the DMARC standard for increasing successful delivery of your users' email, while preventing abuse of your domain name. We will discuss why DMARC is needed to protect your users' email, and how it supercharges enforcement of your SPF & DKIM security policies, while enabling a powerful feedback loop providing you with new insights into how your email is being handled by recipients.

  • What Is DMARC
  • Brief Review of SPF & DKIM
  • How To Setup DMARC
  • How Does DMARC Protect Your Domain
  • Zimbra Settings For DMARC Alignment

The MTA-STS standard advertises to email senders that you prefer strong encryption and provides senders with a means to verify your email servers, while the TLS-RPT standard provides important insights into inbound deliveries that failed due to lacking encryption. A registration link for this next webinar episode should be available within the upcoming weeks.

On Tuesday, June 14th, the fourth episode in the Zimbra Email Security webinar series will premiere. This episode will be an in-depth discussion of how to deploy DNSSEC.

Join us for this fourth episode by registering here.

You will learn how DNSSEC prevents DNS hijacking and forgeries by an adversary, preserving the trust and integrity of your DNS records. Included will be a step-by-step walk through of setting up a domain name with DNSSEC, along with best practices. DNSSEC is also a prerequisite for another important email security standard called DANE that will be discussed in an upcoming webinar series episode.

Just a reminder that the fourth episode in the email security webinar series starts tomorrow, on Tuesday, June 14th. Tomorrow's topic will be DNSSEC.

DNS is universally trusted, but as will be demonstrated in this webinar, is trivial to manipulate by an adversary to bypass many other forms of security you have setup, such as SSL certificates, SPF, DKIM, DMARC, and MTA-STS. Join us to learn what DNSSEC is, how it works, and why you need to deploy it on your network to avoid becoming the next victim.

Hello, I missed this webinar, anywhere where I can find the material ?

for DNSSEC I tried to configure dnsmasq (I use it for split DNS) but lookups fail with unreachable hosts if enabling dnssec
for DANE I found the Zimbra wiki and seems it can be enabled with 2 configuration settings ?
thanks
