Malware prevention

Correct Answer: Uninstall the recently added browser extension

Uninstalling the recently added browser extension will remove the potential cause of excessive pop-up ads. The other options do not directly address the issue and may have negative side effects.

Correct Answer: Apply VPN with multi-factor authentication

Applying a VPN with multi-factor authentication is the best security measure to ensure a safe network environment for remote workers. A VPN (Virtual Private Network) encrypts the data transmitted between remote devices and the organization's network, protecting sensitive information from unauthorized access. Multi-factor authentication adds an extra layer of security by requiring users to provide additional verification (such as a code sent to their phone) in addition to their username and password. This makes it much harder for unauthorized users to gain access, even if they have stolen login credentials. Disabling the firewall would remove a crucial security barrier, leaving the network vulnerable to attacks. Using shared accounts would make it difficult to track individual user actions and could allow unauthorized access if the shared credentials are compromised. Blocking access to cloud storage would hinder remote workers' ability to store and share files securely, but it does not directly address the security of the VPN connection itself.

Correct Answer: Report the email as a potential phishing attempt

The user should report the email as a potential phishing attempt. Phishing emails often try to trick users into entering their login credentials by claiming they need to access a file or update their account information. However, legitimate organizations will never ask for sensitive information like passwords via email. Entering credentials or downloading attachments from unknown sources can lead to malware infections or compromised accounts. The safest action is to report the suspicious email to the company's IT or security team for investigation.
