To ensure data is unrecoverable on a lost or stolen mobile device, the best solution is:

Remote wipe: This feature allows the device owner or IT administrator to remotely erase all data on the device, ensuring that it cannot be recovered by unauthorized users.

Device encryption: While important for protecting data, encryption alone does not remove data from the device.

Data backup: Ensures data is saved elsewhere but does not make it unrecoverable on the lost or stolen device.

Fingerprint reader: Provides security for accessing the device but does not affect data recovery if the device is compromised.

For securing mobile devices with two authentication methods, combining something the user knows (a PIN) with something the user is (biometrics) enhances security by implementing multi-factor authentication.

Smart card: Generally requires additional hardware and is not commonly used in mobile devices.

Biometrics: Uses unique biological traits such as fingerprints or facial recognition, providing a convenient and secure second method of authentication.

Hard token: Involves additional physical devices which might not be practical for mobile devices.

One-time password: Usually used for specific applications rather than as a general device authentication method.

When an organization refuses to pay the ransom for a decryption key after a ransomware attack, and all traces of the infection have been removed, the next critical step is:

Restore critical data from backup: This is the most effective way to recover from a ransomware attack without paying the ransom. Assuming the organization has good backup practices, the backups should be free from infection and can be restored to get the systems operational again.

Scan all of the infected files with up-to-date, anti-malware cleaning software: This step is important during the infection removal process but does not address restoring the encrypted files.

Fully patch the server operating systems hosting the fileshares: While this is necessary to prevent future attacks, it does not recover the encrypted files.

Change the files to be read-only: This will not help recover the encrypted data.

In the Windows OS, to grant a user permissions equivalent to root-level permissions (which means full control over the system), the user needs to be given:

Administrator: The Administrator role provides full control over the system, including the ability to install and uninstall software, change system settings, and access all files and directories.

Power: The Power User role provides some administrative capabilities but not full control. It is a legacy role with fewer permissions than Administrator.

Default: This refers to a standard user account with limited permissions.

Superuser: This term is more commonly associated with Unix/Linux systems and is not a specific role in Windows.

For rendering video, the most critical component a customer should prioritize in a desktop is:

GPU (Graphics Processing Unit): The GPU is specifically designed to handle complex graphics and video rendering tasks. A powerful GPU will significantly improve performance in video rendering applications.

NIC (Network Interface Card): Important for network connectivity but irrelevant for video rendering.

USB: Useful for peripherals but does not impact video rendering capabilities.

HDMI: An important output interface for connecting monitors but not crucial for the rendering process itself.

A cryptominer is a malicious program that uses the CPU resources of a computer to generate cryptocurrency, such as Bitcoin or Ethereum. This can cause the CPU to run at 100% utilization and slow down the system. Spyware, virus and keylogger are other types of malware, but they do not necessarily cause high CPU usage.

yum (Yellowdog Updater Modified) is a package management utility for PCs that are running the Linux operating system. It can be used to install, update and remove software packages from repositories. chmod (change mode) is a command that changes the permissions of files and directories in Linux. man (manual) is a command that displays the documentation of other commands in Linux. grep (global regular expression print) is a command that searches for patterns in text files in Linux.

AutoPlay is a feature that automatically runs programs or files when a removable media device, such as a flash drive, is plugged in. This can be exploited by malware authors who place malicious files on flash drives that execute automatically when inserted into a computer. Turning off AutoPlay can prevent this type of incident by requiring the user to manually open or run files from removable media devices. Disabling UAC (user account control), restricting local administrators and enabling UPnP (universal plug and play) are not effective ways to prevent this type of incident.
