If you have worked on the Salesforce platform for over a few minutes, whether you're a developer or a Salesforce certified admin, you've likely heard the term "best practice" mentioned. But what does it mean? As a Salesforce developer, it's essential to prioritize secure coding practices to protect your organization's data and ensure that your applications are safe from vulnerabilities. Here are some best practices for secure coding in the Salesforce environment.
Implement Access Controls
Access controls ensure only authorized users can access sensitive data or perform critical functions. As a developer, you can implement access controls by defining roles, profiles, and permission sets that limit the data and functionality that users can access based on their job responsibilities.
Encryption is a technique used to protect data by converting it into an unreadable format that can only be decrypted with the proper key. Salesforce provides a range of encryption options, including field encryption, platform encryption, and transport-level encryption.
Field encryption allows you to encrypt specific fields within an object, while platform encryption encrypts all data stored within the platform. Transport-level encryption ensures that data is encrypted as it's transmitted over the internet.

Input sanitization is critical in preventing attacks like SQL injection and cross-site scripting (XSS). When users enter data into your application, you must validate and sanitize it to ensure it doesn't contain malicious code or unexpected characters.
To limit user input to particular forms or patterns, you can use input masks, regular expressions, and validation rules. For example, you can use a regular expression to ensure that an email address entered by a user is in a valid format.
Avoid Hardcoding Sensitive Information
Hardcoding sensitive information like passwords or API keys in your code can be a significant security risk. If an attacker gains access to your code, they can see the sensitive information in plain text.
Instead, you should store sensitive information in protected custom settings or custom metadata types. Your code can access secure, encrypted storage locations at runtime.
Use OAuth for Authentication
OAuth is a secure authentication protocol that provides delegated access to protected resources without sharing credentials. Using OAuth, you can avoid storing usernames and passwords in your code or requiring users to enter their credentials each time they access your application.
Salesforce supports OAuth 2.0, which allows you to authenticate users using external identity providers like Google or Facebook.
Limit Query and Search Results
Salesforce provides robust query and search functionality, but limiting the results returned is essential to prevent data leakage or performance issues. You can use filters, conditions, and limits to restrict the data that are returned by your queries.
You can also use SOQL and SOSL injection prevention techniques like binding variables and parameterized queries to prevent attackers from manipulating your queries to retrieve sensitive information.

Implement Validation Rules
Validation rules ensure that data entered by users meets specific criteria, such as a minimum or maximum value, a specific format, or a required field. By implementing validation rules, you can ensure that data is accurate and complete, which can prevent errors and improve security.
For example, you can create a validation rule requiring a lead record to include a phone number or email address before saving it. This can help prevent incomplete or inaccurate data from entering your system.
To protect data and prevent security vulnerabilities, secure coding practices are essential for Salesforce developers. By implementing access controls, encryption, input sanitization, avoiding hard coding sensitive information, using OAuth for authentication, limiting query and search results, and implementing validation rules, you can ensure that your applications are secure and provide a positive user experience. Follow these essential secure coding practices to ensure your code is secure and protected from threats. Remember that security is a continuous process, and staying up-to-date with the latest security threats and vulnerabilities is essential to ensure your code remains secure.
