How Admins Can Prepare for the Spring 2020 Salesforce Security Update

In March 2020 (after the Spring ’20 Release), Salesforce will start enforcing new security policies specifically for Salesforce public sites (Force.com, Site.com, and Communities). The schedule for rollout will be released in February 2020.

Who does this impact?
All customer organizations with Salesforce Sites, Site.com sites, legacy portals, or community sites. If you aren’t sure whether this impacts your organization, consider that if Salesforce is driving any content that your customers or partners can access, it most probably affects you. For example, this will affect our Simple Survey customers, as the Simple Survey Landing Page uses a Site.com site to present the survey questions and capture the customer responses.

What is this release about? How will this release affect you?
Simply put, the goal is to improve security by enforcing authentication where possible, locking down access to the site guest user. Enabling this limits the visibility and access that guest users have to your org’s data. Let’s review some of the new rules.

  • The Guest User external Org-Wide Defaults (OWD) is always set to private, and this cannot be changed.
  • The Guest User can only be given Create and Read access at most on any object.
  • Guest User sharing rules are the only mechanism to grant guest access to records, which are a special type of criteria-based sharing rule.
  • Read is the maximum access allowed in a guest sharing rule
  • The Guest User cannot be the owner for new records and cannot be re-assigned record ownership.
  • The Guest User cannot Update or Delete access on objects; You will need to use system mode for these types of transactions. See Guest User Record Access Development Best Practices for more information.
  • Guest User cannot be granted “View All Data” And “Modify All Data” access on objects; and Salesforce is retiring the “View All Users” permission for the Guest Profile.
  • You will need to use the Guest User Visibility feature to grant guest user visibility to community members.

What accommodations need to be made for Simple Survey?
We have had to remove a setting that allowed customers to bypass the default sharing model in Simple Survey and create their own security logic. Customers may want to remove any custom sharing settings created for Simple Survey as the new default sharing logic handles everything properly by default. We are performing a push update to all sandbox and production orgs in advance of Salesforce’s rollout to prevent issues related to this setting.

Will this release impact me?
You should test your org to ensure you identify any needed security changes needed. Starting in Winter ‘20, you can test upcoming security changes in your org at no risk, allowing you to roll back at any time. To do so, go to Setup > Security Controls > Security Alerts and follow the steps in each security alert.

We recommend that you have a testing plan to test the changes as stated above. To get started, use the SAMPLE TEST PLAN that Salesforce has provided, which can be found here.
