Answer:
There are several measures you can take to control access to the master production schedules to ensure that only authorized customers can enter their data. Some possible measures are:
Implement strong authentication: Require users to authenticate themselves with a username and password, or use more secure authentication methods such as two-factor authentication or biometric authentication.
Implement access controls: Grant access only to authorized users and restrict access to sensitive data. Access controls can be implemented using various techniques such as role-based access control, mandatory access control, or discretionary access control.
Monitor user activity: Monitor user activity on the system and track access to sensitive data. This can help identify any unauthorized access attempts or suspicious activity.
Implement data encryption: Protect data in transit and at rest by encrypting it. Encryption can help prevent unauthorized access to sensitive data, even if an attacker gains access to the system.
Train users on security awareness: Educate users on security best practices, such as not sharing passwords, logging out after use, and reporting suspicious activity. This can help prevent security breaches due to user error or negligence.
Regularly review security measures: Regularly review security measures to ensure they are effective and up-to-date with the latest security standards and best practices.
