Which of the following controls would help the IT Department achieve this objective?

The IT Department of a financial institution decided to implement preventive controls to avoid potential security breaches. Therefore, they separated the development, testing, and operating equipment, secured their offices, and used cryptographic keys. However, they are seeking further measures to enhance their security and minimize the risk of security breaches.

Which of the following controls would help the IT Department achieve this objective?
A . Alarms to detect risks related to heat, smoke, fire, or water
B . Change all passwords of all systems
C . An access control software to restrict access to sensitive files

Answer: C

Explanation:

An access control software is a type of preventive control that is designed to limit the access to sensitive files and information based on the user’s identity, role, or authorization level. An access control software helps to protect the confidentiality, integrity, and availability of the information by preventing unauthorized users from viewing, modifying, or deleting it. An access control software also helps to create an audit trail that records who accessed what information and when, which can be useful for accountability and compliance purposes.

The IT Department of a financial institution decided to implement preventive controls to avoid potential security breaches. Therefore, they separated the development, testing, and operating equipment, secured their offices, and used cryptographic keys. However, they are seeking further measures to enhance their security and minimize the risk of security breaches. An access control software would help the IT Department achieve this objective by adding another layer of protection to their sensitive files and information, and ensuring that only authorized personnel can access them.

Integrity is the property of safeguarding the accuracy and completeness of information and processing methods. A breach of integrity occurs when information is modified or destroyed in an unauthorized or unintended manner. In this case, Diana accidently modified the order details of a customer without their permission, which resulted in the customer receiving an incorrect product. This means that the information about the customer’s order was not accurate or complete, and therefore, the integrity principle was breached. Availability and confidentiality are two other information security principles, but they were not violated in this case. Availability is the property of being accessible and usable upon demand by an authorized entity, and confidentiality is the property of preventing disclosure of information to unauthorized individuals or systems.
