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:


global with sharing class ApexSecurityRest {


    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];


                 result.Description = result.Account?.Name;



    return result;


    public class FunctionalException extends Exception{}

    public class SecurityException extends Exception{}
