We’re excited to announce changes that make getting Google Trust Services TLS certificates easier for Google Domains customers. With this integration, all Google Domains customers will be able to acquire public certificates for their websites at no additional cost, whether the site runs on a Google service or uses another provider. Additionally, Google Domains is now making an API available to allow for DNS-01 challenges with Google Domains DNS servers to issue and renew certificates automatically.

Like the existing Google Cloud integration, Automatic Certificate Management Environment (ACME) protocol is used to enable seamless automatic lifecycle management of TLS certificates. 

These certificates are issued by the same Certificate Authority (CA) Google uses for its own sites, so they are widely supported across the entire spectrum of devices used to access your services.

How do I use it?

Using ACME ensures your certificates are renewed automatically and many hosting services already support ACME. If you’re running your own web servers / services, there are ACME clients that integrate easily with common servers. To use this feature, you will need an API key called an External Account Binding key. This enables your certificate requests to be associated with your Google Domains account. You can get an API key by visiting Google Domains and navigating to the Security page for your domain. There you’ll see a section for Google Trust Services where you can get your EAB Key.

Example of EAB Credentials in Google Domains

As an example, with the popular Certbot ACME client, the configuration to register an account looks like:

certbot register –email <CONTACT_EMAIL> –no-eff-email –server “https://dv.acme-v02.api.pki.goog/directory”  –eab-kid “<EAB_KEY_ID>” –eab-hmac-key “<EAB_HMAC_KEY>”

The EAB_KEY_ID and EAB_HMAC_KEY are both provided on your Google Domains security page.

After the account is created, you may issue certificates by running:

certbot certonly -d <domain.com> –server “https://dv.acme-v02.api.pki.goog/directory” –standalone

Then follow the prompts to complete validation and download your certificate. If you need additional information please visit the Google Domains help center.

Google Domains and ACME DNS-01

ACME uses challenges to validate domain control before issuing certificates. The ACME DNS-01 challenge can be an efficient way for users to automate the validation process and integrate with existing websites and web hosting services.

Google Domains now provides an API for ACME DNS-01 challenges that helps streamline the process for users to authenticate domain control quickly and securely. This is now offered in some popular ACME clients like Certbot via this plugin, Caddy, Certify The Web, Posh-ACME. You can find additional information on the Google Domains site.

Example of DNS API Access Token in Google Domains

To set up automatic certificate provisioning with ACME and DNS-01, follow these steps:

1. Sign in to Google Domains.
2. Select the domain that you want to use.
3. At the top left, click “Menu” and select “Security”.
4. Under section “ACME DNS API”, click “Create token”.
5. A dialog box will appear with an “API Token”. This is the API Token you will need to enter into your ACME client. You will need to copy this value and can do so by clicking the copy button next to the API Token. 
• NOTE: This value is only shown once. After the dialog box is closed you  will not be able to see this API Token again. Store this token in a safe place, since anyone that has it gains the ability to modify some DNS TXT records for your Domain.  
• If you did not save this value before closing the dialog box, you can easily delete and create a new API token.
• A limit of 10 API tokens per domain can exist at a time. 
6. Once the dialog box is closed you will be able to see in the list that the token has been created. You can delete this token at any time to revoke its access. 
7. The API token can now be used in an ACME client that supports the Google Domains ACME DNS API. Each ACME client differs slightly on how to specify this API Token so you will need to read the documentation on your desired ACME client.

1. Bring Chrome under Cloud Management

Your journey towards keeping your Google Workspace users and data safe, starts with bringing your Chrome browsers under Cloud Management at no additional cost. Chrome Browser Cloud Management is a single destination for applying Chrome Browser policies and security controls across Windows, Mac, Linux, iOS and Android. You also get deep visibility into your browser fleet including which browsers are out of date, which extensions your users are using and bringing insight to potential security blindspots in your enterprise.

Managing Chrome from the cloud allows Google Workspace admins to enforce enterprise protections and policies to the whole browser on fully managed devices, which no longer requires a user to sign into Chrome to have policies enforced. You can also enforce policies that apply when your managed users sign in to Chrome browser on any Windows, Mac, or Linux computer (via Chrome Browser user-level management) –not just on corporate managed devices.

This enables you to keep your corporate data and users safe, whether they are accessing work resources from fully managed, personal, or unmanaged devices used by your vendors.

Getting started is easy. If your organization hasn’t already, check out this guide for steps on how to enroll your devices.

2. Enforce built-in protections against Phishing, Ransomware & Malware

Chrome uses Google’s Safe Browsing technology to help protect billions of devices every day by showing warnings to users when they attempt to navigate to dangerous sites or download dangerous files. Safe Browsing is enabled by default for all users when they download Chrome. As an administrator, you can prevent your users from disabling Safe Browsing by enforcing the SafeBrowsingProtectionLevel policy.

Over the past few years, we’ve seen threats on the web becoming increasingly sophisticated. Turning on Enhanced Safe Browsing will substantially increase protection from dangerous websites, malicious downloads and extensions. For the best protections against web based attacks Google has to offer, enforce Enhanced Safe Browsing for your users.

3. Enable Enterprise Credential Protections in Chrome

Enterprise password reuse introduces significant security risks. Quite often, employees reuse corporate credentials as personal logins and vice versa. Occasionally, employees even enter their corporate passwords into phishing websites. Reused employee logins give criminals easy paths to access corporate data.

Chrome Enterprise Password Reuse detection helps enterprises avoid identity theft and employee and organizational data breaches by detecting when an employee enters their corporate credentials into any other website.

Google Password Manager in Chrome also has a built-in Password Checkup feature that alerts users when Google discovers a username and password has been exposed in a public data breach.

Password alerts are surfaced in Audit Logs and Security Investigation Tool which helps admins create automated rules or take appropriate steps to mitigate this by asking users to reset their passwords.

4. Gain insights into critical security events via Audit Logs, Google Security Center or your SIEM of choice

IT teams can gain useful insights about potential security threats and events that your Google Workspace users are encountering when browsing the web using Chrome. IT teams can take preventive measures against threats through Security Reporting.

In the Google Workspace Admin console, organizations can enroll their Chrome browser and get detailed information about their browser deployment. IT teams can also set policies, manage extensions, and more. The Chrome management policies can be set to work alongside any end user-based policies that may be in place.

Once you’ve enabled Security events reporting (pictured above), you can then view reporting events within audit logs. Google Workspace Enterprise Plus or Education Plus users can use the Workspace Security Investigation Tool to identify, triage, and act on potential security threats.

As of today, Chrome can report on when users:

• Navigate to a known malicious site.
• Download or upload files containing known malware.
• Reuse corporate passwords on non-approved sites.
• Change corporate passwords after reusing them on non-approved sites.
• Install extensions.

In addition to Google Workspace, you can also export these events into other Google Cloud products, such as Google Cloud Pub/Sub, Chronicle, or leading 3rd party products such as Splunk, Crowdstrike and PaloAlto Networks.

5. Mitigate risk by keeping your browsers up to date with latest security updates

Modern web browsers, like any other software, can have “zero day” vulnerabilities, which are undiscovered flaws in the software that can be exploited by attackers until they are identified and resolved. Fortunately, among all the browsers, Chrome is known to patch zero day vulnerabilities quickly. However, to take advantage of this, the IT team has to ensure that all browsers within the browser environment are up-to-date. Our enterprise tools provide a smooth and seamless browser update process, enabling user productivity while maintaining optimal security. By leveraging these tools, businesses can ensure their users are safe and protected from potential security threats.

• Version Report: Easily see all the versions of Chrome in your fleet across various operating systems in a daily report.
• Force Auto Updates in Chrome: Trigger updates to newer versions of Chrome as soon as they’re available. Force users to relaunch Chrome to take updates more rapidly using enterprise policies. This keeps users on the latest version of Chrome, with the latest security fixes.
• Controlling legacy browser usage: Some users continue to need access to old web applications that use plugins and ActiveX technology not supported by modern browsers. Legacy Browser Support functionality is integrated into Chrome, and reduces the time users spend with less secure browsers.

6. Ensure employees only use vetted extensions

Extensions pose a large security risk. Many extensions request powerful permissions that if misused, could lead to security breaches or data loss. However, due to strong end user demand, it’s often not possible to fully block the installation of extensions.

• Apps & Extensions usage report: Provides visibility into every Chrome extension that is installed across an enterprise’s fleet. Admins can force install or block any extension across any segment of their fleet.
• Extensions workflow: Admins can decide under which circumstances an extension install needs to be reviewed by IT. A review workflow in the Google Admin console makes it easy for admins to review and approve install requests for specific users requesting an extension, or for their broader fleet.
• Extensions details: Admins can see additional details about an extension’s permissions, and other relevant metadata. This info is surfaced in the Extensions list and Extensions workflow pages to make it easier for administrators to manage extensions.

7. Ensure your Google Workspace resources are only accessed from Managed Chrome Browsers with protections enabled

Context-Aware Access ensures only the right people, under the right conditions, access confidential information. Using Context-Aware Access, you can create granular access control policies for apps that access Workspace data based on attributes, such as user identity, location, device security status, and IP address.

To ensure that your Google Workspace resources are only accessed from managed Chrome browsers with protection enabled, you create custom access levels in Advanced mode, using Common Expressions Language (CEL). Learn more about managed queries in this help center article.

8. Enable BeyondCorp Enterprise Threat and Data Protections

For the organizations that want to take an even more proactive approach to data security, they can deploy BeyondCorp Enterprise to protect their information and enable data loss prevention (including control over upload, download, print, save, copy and paste), real-time phishing protection, malware deep scanning, and Zero Trust access to SaaS applications. Since BeyondCorp Enterprise is already built into Chrome, organizations can frictionlessly implement it without having to install additional agents.
