 Group Policy is a feature of Windows that allows administrators to centrally manage and configure the settings of computers and users in a domain network. Group Policy can be used to modify the default home page of all the workstations in a company by creating and applying a policy that specifies the desired URL for the home page. This way, the change will be automatically applied to all the workstations that are joined to the domain and receive the policy.

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

A VPN (Virtual Private Network) is a service that allows remote employees to access the company’s network resources securely over the internet as if they were on premises. A VPN encrypts the data traffic between the employee’s device and the VPN server, and assigns the employee a virtual IP address that belongs to the company’s network. This way, the employee can access the local servers, files, printers, and other resources without exposing them to the public internet. A VPN also protects the employee’s privacy and identity by masking their real IP address and location.

The customer’s web browser is likely infected by a browser hijacker, which is a type of malware that changes the browser’s settings and redirects the user to malicious websites. A browser hijacker can also steal the user’s personal data, display unwanted ads, and install more malware on the device. To remove a browser hijacker, the user should first uninstall the browser from the Control Panel, then scan the device with an antivirus or anti-malware program, and finally install a trusted browser from a legitimate source. Deleting the browser cookies and history, resetting the browser settings, or changing the browser default search engine may not be enough to get rid of the browser hijacker, as it may have embedded itself into the system or other browser components. 

Risk analysis is the process of identifying and evaluating the potential threats and impacts of a change on the system, network, or service. It is an essential step before approving a change request, as it helps to determine the level of risk, the mitigation strategies, and the contingency plans. Risk analysis also helps to prioritize the change requests based on their urgency and importance12.

The ext3 file system is a Linux native file system that meets the requirements of the question. It has the following features:

All changes are tracked. The ext3 file system uses a journaling mechanism that records all changes to the file system metadata in a special log called the journal before applying them to the actual file system. This ensures that the file system can be restored to a consistent state in case of a power failure or system crash12.

The possibility of file corruption is reduced. The journaling feature of ext3 also reduces the possibility of file corruption, as it avoids the need for a full file system check after an unclean shutdown. The file system can be quickly replayed from the journal and any inconsistencies can be fixed12.

Data recovery is easy. The ext3 file system supports undeletion of files using tools such as ext3grep or extundelete, which can scan the file system for deleted inodes and attempt to recover the data blocks associated with them34.

A technician needs to reimage a desktop in an area without network access, which means that the technician cannot use network-based methods such as PXE or SMB to deploy the image. Therefore, the technician should use offline methods that involve removable media such as USB or optical media. USB and optical media are common ways to store and transfer system images, and they can be used to boot the desktop and initiate the reimaging process. The technician will need to create a bootable USB or optical media that contains the system image and the imaging software, and then insert it into the desktop and change the boot order in the BIOS or UEFI settings. The technician can then follow the instructions on the screen to reimage the desktop

Open-source software is software that has its source code available for anyone to inspect, modify, and distribute. Open-source software is usually free of charge and does not require a license to use. Some examples of open-source antivirus software are ClamAV, Comodo, and Immunet12. The other license types are either not free or not suitable for a SOHO PC. Corporate and enterprise licenses are designed for large-scale organizations and networks, and they usually require a subscription fee. Personal licenses are for individual users and may have limited features or support.
