Salesforce Sharing and Visibility Certification Practice Exam

What should be used to enforce data security when exposing a web service to business partners?

1. Create a custom Apex Web Service using the "With Sharing" keyword

2. Give each partner their own Salesforce login set to API Enabled

3. Query the Orders object with Dynamic SOQL based on the fulfillment ID

4. Set the Orders object's sharing settings to Private

The correct answer is: Create a custom Apex Web Service using the "With Sharing" keyword

Using a custom Apex Web Service with the "With Sharing" keyword is an effective way to enforce data security when exposing a web service to business partners because it ensures that the sharing rules of the current user are respected. When the "With Sharing" keyword is employed, the Apex class enforces the sharing rules defined for the data being accessed. This means that business partners can only access the data they are permitted to see based on their roles and sharing settings. Implementing this approach gives fine-grained control over what data is exposed through the web service, allowing for adherence to the organization’s data security policies. By ensuring that the web service respects the sharing rules, you reduce the risk of unauthorized access to sensitive information, thus enhancing the trustworthiness of the integration with business partners. While other choices may offer some level of security, they do not provide the same level of customized control over data access as using the "With Sharing" keyword in a custom Apex Web Service. Providing separate logins for each partner or adjusting object sharing settings may enhance security, but they can also lead to increased administrative overhead or may not adequately encapsulate the specific permissions desired for controlled access. Dynamic SOQL queries can limit access based on the query structure but may not inherently enforce sharing
