How can you prevent malicious input in SFCC applications?

Validating and sanitizing user inputs before processing is essential for preventing malicious input in SFCC applications. This practice involves checking the data for correctness and appropriateness while ensuring that harmful data is either rejected or cleaned before it can cause any damage or unintended behavior in the application. By implementing strong validation rules based on expected data types, formats, and length, developers can effectively mitigate risks such as SQL injection, cross-site scripting (XSS), and other injection attacks.

Sanitization complements validation by removing or neutralizing harmful characters or code from user inputs. For instance, stripping out scripts or SQL commands embedded in a user's input ensures that any potentially dangerous data does not get executed or stored improperly. This dual approach reinforces the security posture of the application by addressing both the validity and safety of the data being handled.

The other choices do not directly address preventing malicious input effectively. Relying solely on default validation methods may not be adequate, as they may not cover all possible threats or scenarios specific to your application. Logging all user inputs does have benefits for monitoring and auditing but does not prevent malicious input from being processed in the first place. Setting security policies is vital for guiding overall security strategy but doesn't replace the need for active validation and sanitization processes in handling
