What type of authentication must be used for remote access according to the memo released after the Veterans Affairs incident?

• A. Single-factor authentication
• B. Two-factor authentication with a separate device
• C. Biometric authentication
• D. Username and password authentication

Answer: (B)

The requirement for two-factor authentication with a separate device stems from the need to enhance security measures for remote access, especially in light of vulnerabilities exposed by previous incidents such as the one involving Veterans Affairs. Two-factor authentication (2FA) provides an additional layer of security by requiring two different forms of verification before granting access. This typically includes something the user knows (like a password) and something the user has (such as a smartphone or hardware token). Implementing 2FA mitigates the risk of unauthorized access, as it significantly reduces the chances that someone can compromise an account simply by obtaining a password. By utilizing a separate device, it ensures that even if an attacker gains access to a user's password, they would still need the second factor to successfully authenticate and gain entry. This approach aligns with best practices for securing sensitive information and systems, particularly in contexts like federal IT, where the consequences of a breach can be severe. In contrast, options such as single-factor authentication or username and password alone do not offer enough protection against modern threats. They rely solely on one form of validation, which can be more easily bypassed. Biometric authentication, while secure, may not be universally applicable or feasible for all users or situations, especially in remote access scenarios.
