WPA2/AES (Wi-Fi Protected Access 2/Advanced Encryption Standard) is a wireless security standard that supports enterprise mode, which allows a user to use login credentials (username and password) to authenticate to available corporate SSIDs (service set identifiers). TACACS+ (Terminal Access Controller Access-Control System Plus) and Kerberos are network authentication protocols, but they are not wireless security features. Preshared key is another wireless security feature, but it does not use login credentials.

One of the possible ways to access the user’s computer remotely is to use RDP, which stands for Remote Desktop Protocol. RDP is a protocol that allows a user to connect to another computer over a network and use its graphical interface. RDP is commonly used for remote desktop software, such as Microsoft Remote Desktop Connection1. To use RDP, the user’s computer must run RDP server software, and the technician must run RDP client software. The technician can then enter the user’s IP address or hostname, and provide the appropriate credentials to log in to the user’s computer. Once connected, the technician can view and control the user’s desktop, and review the Outlook settings.

A recovery key is a code that can be used to unlock a BitLocker-encrypted drive when the normal authentication methods (such as password or PIN) are not available or have been forgotten. BitLocker is a feature of Windows that encrypts the entire drive to protect data from unauthorized access. If a technician is trying to repair a Windows 10 OS that has BitLocker enabled, they will need the recovery key to access the drive and continue the OS repair. SSL key, preshared key, and WPA2 key are not keys that are related to BitLocker or OS repair.

Shoulder surfing is a threat that involves someone looking over another person’s shoulder to observe their screen, keyboard, or other sensitive information. Shoulder surfing can be used to steal passwords, personal identification numbers (PINs), credit card numbers, or other confidential data. The use of a privacy screen on a computer can help prevent shoulder surfing by limiting the viewing angle of the screen and making it harder for someone to see the screen from the side or behind. Impersonation, whaling, and tailgating are not threats that can be prevented by using a privacy screen on a computer.
