    Solution

    Implementing Multi-Factor Authentication (MFA) is a best practice for securing remote access in both Windows and Unix/Linux environments. MFA adds an additional layer of security by requiring users to provide two or more verification factors to gain access to a system or application. This approach significantly reduces the likelihood of unauthorized access, as even if a user's password is compromised, an attacker would still need the second factor (e.g., a one-time code sent to a mobile device) to gain entry. By utilizing MFA, organizations can protect sensitive data and systems against various attack vectors, including phishing and brute force attacks. Moreover, the adoption of MFA aligns with compliance requirements set forth by various regulations and industry standards, thereby enhancing the overall security posture of the organization. In an era where remote access is increasingly common, implementing MFA is crucial for safeguarding assets and maintaining trust with users. Option A (Access via public Wi-Fi without encryption) - Allowing access via unsecured public Wi-Fi exposes users to significant risks, including man-in-the-middle attacks, as data can be intercepted by malicious actors. Option C (Disabling firewalls) - Disabling firewalls compromises the network's first line of defense against unauthorized access and attacks, making systems more vulnerable to threats. Option D (Default settings for VPN configurations) - Using default settings for VPN configurations can create vulnerabilities, as these are often well-known to attackers and can be exploited if not customized for security. Option E (Sharing access credentials via unsecured channels) - Sharing access credentials through unsecured channels increases the risk of interception and unauthorized access, directly contradicting fundamental security practices.
