BitLocker is a Windows security feature that provides encryption for entire volumes, addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices1. BitLocker helps mitigate unauthorized data access by enhancing file and system protections, rendering data inaccessible when BitLocker-protected devices are decommissioned or recycled1. Network share, Group Policy, and Static IP are not features that can prevent unauthorized data access if a computer is lost or stolen.

The Network & Internet settings in Windows 10 allow the user to input the SSID and password of a Wi-Fi network, as well as manage other network-related options, such as airplane mode, mobile hotspot, VPN, proxy, etc1. To access the Network & Internet settings, the user can select the Start button, then select Settings > Network & Internet2. Alternatively, the user can right-click the Wi-Fi icon on the taskbar and click "Open Network & Internet Settings"3.

The System settings in Windows 10 allow the user to configure the display, sound, notifications, power, storage, and other system-related options1. The Personalization settings in Windows 10 allow the user to customize the background, colors, lock screen, themes, fonts, and other appearance-related options1. The Accounts settings in Windows 10 allow the user to manage the user accounts, sign-in options, sync settings, and other account-related options1.

The best course of action for the technician is to restore the defaults and reimage the corporate OS on the device. This will remove the jailbreak and any unauthorized or malicious apps that may have been installed on the device, as well as restore the security features and policies that the company has set for its devices. This will also ensure that the device can receive the latest updates and patches from the manufacturer and the company, and prevent any data leakage or compromise from the device.

Jailbreaking is a process of bypassing the built-in security features of a device to install software other than what the manufacturer has made available for that device1. Jailbreaking allows the device owner to gain full access to the root of the operating system and access all the features1. However, jailbreaking also exposes the device to various risks, such as:

The loss of warranty from the device manufacturers2.

Inability to update software until a jailbroken version becomes available2.

Increased security vulnerabilities32.

Decreased battery life2.

Increased volatility of the device2.

Some of the signs of a jailbroken device are:

A high number of ads, which may indicate the presence of adware or spyware on the device3.

Receiving data-usage limit notifications, which may indicate the device is sending or receiving data in the background without the user’s knowledge or consent3.

Experiencing slow response, which may indicate the device is running unauthorized or malicious apps that consume resources or interfere with the normal functioning of the device3.

Finding apps or icons that the user did not install or recognize, such as Cydia, which is a storefront for jailbroken iOS devices1.

The other options are not sufficient or appropriate for dealing with a jailbroken device. Running an antivirus and enabling encryption may not detect or remove all the threats or vulnerabilities that the jailbreak has introduced, and may not restore the device to its original state or functionality. Backing up the files and doing a system restore may not erase the jailbreak or the unauthorized apps, and may also backup the infected or compromised files. Undoing the jailbreak and enabling an antivirus may not be possible or effective, as the jailbreak may prevent the device from updating or installing security software, and may also leave traces of the jailbreak or the unauthorized apps on the device.

A warning message in the user’s browser stating the site’s certificate cannot be verified indicates that the site may be insecure, fraudulent, or malicious. This could be a sign of a phishing attempt, where the sender of the email tries to trick the user into clicking a link that leads to a fake website that mimics a legitimate one, in order to steal the user’s personal or financial information. The most appropriate action for a technician to take in this situation is to close the browser window and report the email to IT security, who can investigate the source and content of the email, and take the necessary steps to protect the user and the network from potential harm. Clicking proceed could expose the user to malware, identity theft, or data breach. Reporting the employee to the human resources department for violating company policy is unnecessary and harsh, as the user may not have been aware of the phishing attempt or the company policy. Restoring the computer from the last known backup is premature and ineffective, as the user may not have been infected by anything, and the backup may not remove the email or the link from the user’s inbox
