Explanation
Multifactor authentication (B) requires users to prove their identity using two or more factors (something you know, have, or are), making unauthorized access significantly harder even if a password is stolen. Trusted software sources (D) ensure that only vetted, signed applications from reputable repositories or app stores are installed, drastically reducing the risk of malware infection. Together, these two controls address the two most common attack vectors: credential compromise and malicious software. ACLs (A) control resource permissions but do not authenticate users. Organizational units (C) are Active Directory administrative containers, not a security control. Pre-shared keys (E) are used for network/VPN authentication, not general device security.
