Answer:
Implementing access restrictions
Explanation:
A preventive control in the information technology area is designed to proactively minimize or prevent the occurrence of security incidents or risks. Out of the options given, implementing access restrictions is a preventive control.
Here's an explanation for each option:
A) Monitoring system logs: This is an example of detective control because it involves reviewing system logs to identify any suspicious or abnormal activities that may have already occurred.
B) Investigating security incidents: This is an example of corrective control because it involves investigating and responding to security incidents that have already occurred to mitigate their impact and prevent future occurrences.
C) Implementing access restrictions: This is a preventive control. By implementing access restrictions, such as strong passwords, user authentication, and role-based access controls, organizations can prevent unauthorized individuals from gaining access to sensitive information or systems.
D) Conducting post-incident reviews: This is an example of a corrective control because it involves analyzing and reviewing security incidents after they have occurred to identify the root causes, learning from them, and making improvements to prevent similar incidents in the future.
In summary, out of the given options, implementing access restrictions is a preventive control because it helps prevent unauthorized access to information or systems before any security incidents occur.
In IT, controls such as preventive, detective, and corrective are employed. Among the provided options, 'implementing access restrictions' is recognized as a preventive control, which aims to avert potential security threats.
In the field of information technology, controls are essential for maintaining integrity, confidentiality, and availability of information systems. Controls are divided into three categories: preventive, detective, and corrective controls. Of the options provided, the method of implementing access restrictions is considered a preventive control.
Preventive controls are designed to prevent security threats from coming to fruition. These can include firewalls, secure passwords, access control lists, authentication methods, and separation of duties. Hence, implementing access restrictions restricts unauthorized users from accessing the data they are not permitted to view, thereby minimizing the chance of a security breach in the first place.

We will be taking a lot of assumptions in this question. Assuming that Landan did not accidentally drop his laptop, as a technician, what I would want to check first is the BIOS settings. There are a couple of issues that can cause this error. These issues may include a boot sector virus that erased the whole hard drive, a bad windows installation, or even a loose cable. Before I check on the BIOS settings, I would request him to unplug any external hard disks. He might have been watching his movies from the hard disk and the disk being connected might be the one causing the error. A wrong boot order in the BIOS settings may be giving priority to another boot source disk like the external hard disk mentioned. I should be able to take Landan through steps that he needs to take to make his hard disk priority. I would also check for corrupt sectors by running the inbuilt CHKDSK tool. If these options don’t work, I would consider checking the hardware itself for further diagnostics.
Hard drive might not be detected due to various reasons. Some problem can be fixed only by the hardware engineer or technical person, few other can be fixed by self by “troubleshooting”. The possible reason could be, BIOS might not have switched on the hard drive so it has not detected. Sometimes data cable might be unplugged.
So you can try replacing one another cable. Another possible reason could be virus. Virus might have corrupted all the data in the hard drive. So anti-virus can be installed to rectify this.
