→ Get Hands-on With Field- and Object-Level Security and Safe Navigation Operator

Launch the org you’ll use for the hands-on challenge, then do the following.

• Create a new custom field on the Contact object to establish a field that contains sensitive and confidential data.
  ○ Field Label: Top Secret
  ○ Type: Text
  ○ Field Name: Top_Secret
  ○ Length: 255

• Uncheck the Visible box for the Standard User profile when defining field-level security.

That’s it for setup. You’ll use the code block below for an Apex class to complete the hands-on challenge.

ApexSecurityRest code block:

@RestResource(urlMapping='/apexSecurityRest')
global with sharing class ApexSecurityRest {
    @HttpGet
    global static Contact doGet(){
        Id recordId = RestContext.request.params.get('id');
        Contact result;
        if (recordId == null){
            throw new FunctionalException('Id parameter is required');
        }
        List<Contact> results = [SELECT id, Name, Title, Top_Secret__c, Account.Name FROM Contact WHERE Id = :recordId];
       SObjectAccessDecision securityDecision = Security.stripInaccessible(AccessType.READABLE ,results);             
       if (!results.isEmpty()) {
       result = results[0];
            if(Schema.sObjectType.Contact.fields.Description.isUpdateable()){
                 result.Description = result.Account?.Name;
            }
	}
    return result;
    }
    public class FunctionalException extends Exception{}
    public class SecurityException extends Exception{}
}
