To answer this question, you need to understand the importance of protecting software and data. Let's go through each option to understand why it is correct or incorrect:
Option A) Screen applicants to be sure they have no previous records - This option is not the most important procedure to protect software and data. While it is important to screen applicants for security purposes, it is not the most crucial procedure for protecting software and data.
Option B) Guard passwords and frequently change them - This option is important for protecting software and data, as strong passwords and regular password changes can help prevent unauthorized access. However, it is not the most important procedure.
Option C) Make frequent backups of data and store them in remote locations - This option is the most important procedure to protect software and data. Making frequent backups of data ensures that even if the original data is lost or compromised, it can be restored from the backups. Storing backups in remote locations adds an extra layer of protection against physical disasters or theft.
Option D) Audit data and programs once a year - While auditing data and programs is important for maintaining the integrity and security of software and data, it is not the most important procedure. Regular audits can help identify vulnerabilities and ensure compliance, but they should be done more frequently than once a year to be effective.
The correct answer is Option C. This option is correct because making frequent backups of data and storing them in remote locations is the most important procedure to protect software and data. It ensures that data can be recovered in case of loss or compromise.
