Which of the following provide the MOST security for PCs and mobile devices? (Choose two.)
Click on the arrows to vote for the correct answer
A. B. C. D. E. F.BD.
The two options that provide the MOST security for PCs and mobile devices are:
B. Multifactor authentication: This is a security measure that requires users to provide two or more forms of identification to access a device or system. The factors can include something the user knows (like a password), something the user has (like a smart card), or something the user is (like a fingerprint). Multifactor authentication provides an additional layer of security beyond just a password or PIN, making it much harder for unauthorized users to gain access.
D. Trusted software sources: Using trusted software sources ensures that the software installed on a device is legitimate and free of malware. By downloading software from reputable sources, users can greatly reduce the risk of downloading malicious software that can compromise the security of their device. Trusted software sources can include official app stores, trusted software vendors, and well-known download sites.
The other options listed also have security benefits but may not provide the MOST security for PCs and mobile devices.
A. Access control lists: These are used to restrict access to specific resources or systems based on user or group permissions. While they can help limit access to certain areas of a device or network, they are not the most effective security measure.
C. Organizational unit: An organizational unit is a way to organize users and resources within a network. While this can help with management and access control, it is not a security measure in itself.
E. Data loss prevention: Data loss prevention is a security measure used to prevent the unauthorized transmission of sensitive data outside of a network. While this can help protect sensitive data, it is not the most effective security measure for overall device and system security.
F. Pre-shared key: A pre-shared key is a passphrase used for authentication between devices or users. While it can provide some level of security, it is not as strong as multifactor authentication and does not provide the most security for PCs and mobile devices.
