What is Multi-Factor Authentication (MFA) relevant to firewalls?

Multi-Factor Authentication (MFA) is significant in the context of firewalls as it involves a security mechanism that requires users to provide multiple forms of verification before gaining access to a network or system. This might include something the user knows (like a password), something the user has (like a mobile device for a verification code), or something the user is (like a fingerprint or facial recognition).

Implementing MFA enhances security by ensuring that even if one factor, such as a password, is compromised, unauthorized access to the firewall and its associated network resources is still prevented, as the attacker would need additional verification methods to gain access. This layered security approach helps reinforce the overall integrity of the firewall’s defensive capabilities.
