The major advantage of automating internal controls is to efficiently test large volumes of data, because automated controls can perform repetitive tasks faster, more accurately, and more consistently than manual controls. Automated controls can also provide audit trails and exception reports that facilitate the monitoring and evaluation of the control effectiveness12. Reviewing large value transactions, identifying transactions with no segregation of duties, and performing analytical reviews are possible benefits of automating internal controls, but not the major advantage.

Comprehensive and Detailed Step-by-Step Explanation:
SFTP (Secure File Transfer Protocol)is the most secure option for transferring data over the internet, as it encrypts both commands and data, ensuring confidentiality and integrity.
* SFTP (Correct Answer - C)
* Uses SSH (Secure Shell) for encryption.
* Provides authentication and encryption for secure data transfers.
* Example:A company uses SFTP to securely transmit payroll files to a third-party processor.
* UDP (Incorrect - A)
* Faster but lacks encryption and data integrity checks.
* HTTP (Incorrect - B)
* Transfers data in plaintext and is vulnerable to interception.
* RDP (Incorrect - D)
* Used for remote desktop access, not secure file transfers.

The greatest risk associated with storing customer data on a web server is data confidentiality. Data confidentiality is the property that ensures that data are accessible only to authorized entities or individuals, and protected from unauthorized disclosure or exposure. Storing customer data on a web server poses a high risk to data confidentiality, as web servers are exposed to the internet and may be vulnerable to various types of attacks or breaches that can compromise the security and privacy of customer data, such as hacking, phishing, malware, denial of service (DoS), etc. Customer data may contain sensitive or personal information that can cause harm or damage to customers or the organization if disclosed or exposed, such as identity theft, fraud, reputation loss, legal liability, etc. Data availability is the property that ensures that data are accessible and usable by authorized entities or individuals when needed. Data availability is a risk associated with storing customer data on a web server, as web servers may experience failures or disruptions that can affect the accessibility and usability of customer data, such as hardware faults, network issues, power outages, etc.
However, data availability is not the greatest risk associated with storing customer data on a web server, as it does not affect the security and privacy of customer data. Data integrity is the property that ensures that data are accurate and consistent, and protected from unauthorized modification or corruption. Data integrity is a risk associated with storing customer data on a web server, as web servers may be subject to attacks or errors that can affect the accuracy and consistency of customer data, such as injection attacks, tampering, replication issues, etc. However, data integrity is not the greatest risk associated with storing customer data on a web server, as it does not affect the security and privacy of customer data. Data redundancy is the condition of having duplicate or unnecessary data in a database or system. Data redundancy is not a risk associated with storing customer data on a web server, but rather a result of poor database design or management.

Requiring a key code to be entered on the printer to produce hard copy is a method to prevent disclosure of classified documents printed on a shared printer. This is because requiring a key code adds an extra layer of security and authentication to the printing process, ensuring that only authorized users can access and retrieve the printed documents. Requiring a key code also prevents unauthorized users from viewing or tampering with the documents while they are in the printer's queue or output tray1.
Using passwords to allow authorized users to send documents to the printer is not a sufficient method to prevent disclosure of classified documents printed on a shared printer. This is because passwords only protect the transmission of the documents from the user's computer to the printer, but they do not protect the documents once they are printed. Passwords can also be compromised or forgotten by users, making them vulnerable to unauthorized access or denial of service2.
Encrypting the data stream between the user's computer and the printer is not a sufficient method to prevent disclosure of classified documents printed on a shared printer. This is because encryption only protects the confidentiality and integrity of the documents while they are in transit, but they do not protect the documents once they are printed. Encryption can also introduce performance issues or compatibility problems with different printers or devices2.
Producing a header page with classification level for printed documents is not a method to prevent disclosure of classified documents printed on a shared printer. This is because producing a header page only informs the users about the sensitivity and handling of the documents, but it does not prevent unauthorized users from accessing or viewing them. Producing a header page can also waste paper and ink, as well as increase the risk of misplacing or mixing up the documents
