How can network authentication be restricted in Salesforce?

Restricting network authentication in Salesforce can be effectively achieved by utilizing login hours and IP ranges. This method allows organizations to define specific timeframes during which users can access Salesforce and limit access based on geographic locations or trusted IP addresses.

When login hours are set, any authentication attempts made outside of these defined hours will be denied, thereby enhancing security by ensuring that users can only log in when they are expected to be active. Furthermore, by defining IP ranges, organizations can restrict access to Salesforce to only those IPs that are known and trusted, minimizing the risk of unauthorized access from unknown or potentially malicious sources.

This control mechanism is essential for maintaining the integrity and security of sensitive data within Salesforce, as it helps organizations to enforce stringent access protocols tailored to their operational needs.
