Ensuring the security of user interfaces and data access is a top priority for any Salesforce Platform Developer. It is essential to understand the various security features and best practices available within the platform to prevent vulnerabilities and protect sensitive information. Developers must consider how to implement secure access controls, prevent cross-site scripting (XSS) attacks, enforce CRUD and FLS permissions, and utilize sharing settings in their custom user interface components.
Question:
Universal Containers wants to ensure that their custom Lightning Web Component (LWC) adheres to best practices for user interface and data access security. Which of the following actions should they take to achieve this goal? (Choose two.)
A. Use the with sharing keyword in Apex classes to enforce record-level access control.
B. Use the without sharing keyword in Apex classes to ensure that all users can access necessary data.
C. Utilize the lightning-input component to mitigate cross-site scripting (XSS) attacks.
D. Bypass CRUD and FLS checks in Apex classes to optimize performance.
E. Ensure that the LWC enforces CRUD and FLS permissions when displaying or modifying records.
Answer: A, C
Explanation:
A. Using the with sharing keyword in Apex classes enforces record-level access control, ensuring that users can only access records they have permission to view or modify. This helps maintain the security of data access in custom components.
C. Utilizing the lightning-input component in LWCs provides built-in protection against cross-site scripting (XSS) attacks. The lightning-input component automatically sanitizes user input and prevents malicious scripts from being executed.
Option B is incorrect because using the without sharing keyword would allow Apex classes to bypass record-level access control, which could result in unauthorized data access. Option D is incorrect because bypassing CRUD and FLS checks in Apex classes may lead to data access vulnerabilities and compromise the security of the user interface. Option E is correct in principle, but it is not a specific action to take; rather, it is a best practice to follow when developing custom components.
