The correct answers are E and F. Disabling AutoRun and updating the antivirus definitions are two actions that should be taken to prevent the incident from happening again.
AutoRun is a feature of Windows that automatically executes a predetermined action when a removable media such as a USB drive is inserted in a computer. For example, AutoRun can launch or install a new program on the media, or open the file in File Explorer. However, this feature can also be exploited by malicious software that can run without the user's consent or knowledge.Therefore, disabling AutoRun can help prevent accidental installation of viruses and other malware from USB drives123.
Updating the antivirus definitions is another important action that can help prevent malware infections from USB drives. Antivirus definitions are files that contain information about the latest known threats and how to detect and remove them.By updating the antivirus definitions regularly, you can ensure that your antivirus software canrecognize and block any malicious software that may be on the USB drivebefore it can harm your computer45.
A host-based IDS is a system that monitors and analyzes the activity on a single computer or device for any signs of intrusion or malicious behavior. A host-based IDS can help detect and prevent malware infections from USB drives, but it is not a sufficient action by itself.A host-based IDS needs to be complemented by other security measures, such asdisabling AutoRun and updating the antivirus definitions6.
Restricting login times, enabling a BIOS password, and updating the password complexity are all actions that can help improve the security of a computer or device, but they are not directly related to preventing malware infections from USB drives. These actions can help prevent unauthorized access to the computer or device, but they do not affect how the computer or device interacts with the USB drive or its contents.
Restricting user permissions is an action that can help limit the damage that malware can cause on a computer or device, but it does not prevent the malware from being installed in the first place. Restricting user permissions means limiting what actions a user can perform on the computer or device, such as installing or deleting programs, modifying system settings, or accessing certain files or folders.By restricting user permissions, you can reduce the impact of malware infections by preventing them from affecting other users or system components7.
