The error message indicates that the website’s security certificate is not trusted by the user’s device, which may prevent the user from accessing the secure internal network. To resolve this issue, the user can view the certificate details and install it on the device, which will add it to the trusted root certificate store. Reimaging the system and installing SSL, installing Trusted Root Certificate, or continuing to access the website are not recommended solutions, as they may compromise the security of the device or the network.

The best option for the technician to demonstrate proper communication techniques and professionalism is to contact the customer if the technician is arriving late. This shows respect for the customer’s time and expectations, and allows the customer to adjust their schedule accordingly. It also helps to maintain a positive relationship and trust between the technician and the customer. The technician should apologize for the delay and provide a realistic estimate of their arrival time. The technician should also thank the customer for their patience and understanding.

The other options are not appropriate or professional. Do not notify the customer if arriving before the customer is not a good practice, as it may cause confusion or frustration for the customer. The customer may have made other plans or arrangements based on the technician’s original schedule, and may not be available or prepared for the service. Dismiss the customer and proceed with the after-hours work is rude and disrespectful, as it ignores the customer’s needs and preferences. The customer may have questions or concerns about the service, or may want to supervise or verify the work. The technician should always communicate with the customer before, during, and after the service. Disclose the experience via social media is unethical and unprofessional, as it may violate the customer’s privacy and the company’s policies. The technician should not share any confidential or sensitive information about the customer or the service on social media, or make any negative or inappropriate comments about the customer or the situation.

A software firewall is a program that monitors and controls the incoming and outgoing network traffic on a computer or a server. A software firewall can help prevent unauthorized LAN devices from accessing stored files on a company file server by applying rules and policies that filter the network packets based on their source, destination, protocol, port, or content. A software firewall can also block or allow specific applications or services from communicating with the network, and alert the administrator of any suspicious or malicious activity12.

A software firewall is a better option than the other choices because:

• Password complexity (B) is a good practice to protect the file server from unauthorized access, but it is not sufficient by itself. Password complexity refers to the use of strong passwords that are hard to guess or crack by attackers, and that are changed frequently and securely. Password complexity can prevent brute force attacks or credential theft, but it cannot stop network attacks that exploit vulnerabilities in the file server software or hardware, or that bypass the authentication process34.
• Antivirus application © and anti-malware scans (D) are important tools to protect the file server from viruses and malware that can infect, damage, or encrypt the stored files. However, they are not effective in preventing unauthorized LAN devices from accessing the files in the first place. Antivirus and anti-malware tools can only detect and remove known threats, and they may not be able to stop zero-day attacks or advanced persistent threats that can evade or disable them. Moreover, antivirus and anti-malware tools cannot control the network traffic or the file server permissions, and they may not be compatible with all file server platforms or configurations56.

System Restore is a feature that allows the user to revert the system to a previous state. However, this can also restore the malware that was removed by the technician. Disabling System Restore can prevent the operating system from automatically returning to an infected state. Enabling antivirus, educating the user, and enabling System Restore are good preventive measures, but they do not address the question. Disabling antivirus can make the system more vulnerable to malware attacks
