Which of the following network vulnerability scan indicators BEST validates a successful, active scan?

A. The scan job is scheduled to run during off-peak hours.

B. The scan output lists SQL injection attack vectors.

C. The scan data identifies the use of privileged-user credentials.

D. The scan results identify the hostname and IP address.

I do not think it is D since host name and IP can be found using passive methods. They are not usually hidden. It is not A, it does not matter when the job is scheduled, it does not indicate a successful scan. It is not C, why would a vulnerability scan indicate a use of privileged user. Unless I do not understand what hat means. So it must be B. Since it is identifying an attack vector.

An analyst wants to implement a more secure wireless authentication for office access points. Which of the following technologies allows for encrypted authentication of wireless clients over TLS? A. PEAP B. EAP C. WPA2 D. RADIUS

A. PEAP EAP by itself is only an authentication framework. PEAP (Protected Extensible Authentication Protocol) fully encapsulates EAP and is designed to work within a TLS (Transport Layer Security) tunnel that may be encrypted but is authenticated. The primary motivation behind the creation of PEAP was to help correct the deficiencies discovered within EAP since that protocol assumes that the communications channel is protected. As a result, when EAP messages are able to be discovered in the "clear" they do not provide the protection that was assumed when the protocol was originally authored. PEAP, EAP-TTLS, and EAP-TLS "protect" inner EAP authentication within SSL/TLS sessions.

As part of a new industry regulation, companies are required to utilize secure, standardized OS settings. A technical must ensure the OS settings are hardened. Which of the following is the BEST way to do this? A. Use a vulnerability scanner. B. Use a configuration compliance scanner. C. Use a passive, in-line scanner. D. Use a protocol analyzer.

B. Use a configuration compliance scanner. A compliance check scans the target and returns results based on if the target is compliant based on the standards selected for the scan. This offers an administrator to see how their systems are configured and if they are compliant with their company's standards. On the other hand, a vulnerability scan offers information pertaining to if the target has known vulnerabilities. https://community.tenable.com/s/article/How-is-a-compliance-check-different-than-a-vulnerability-scan

A security analyst wishes to increase the security of an FTP server. Currently, all traffic to the FTP server is unencrypted. Users connecting to the FTP server use a variety of modern FTP client software. The security analyst wants to keep the same port and protocol, while also still allowing unencrypted connections. Which of the following would BEST accomplish these goals? A. Require the SFTP protocol to connect to the file server. B. Use implicit TLS on the FTP server. C. Use explicit FTPS for connections. D. Use SSH tunneling to encrypt the FTP traffic.

C. Use explicit FTPS for connections. The key part in this question is: "MODERN FTP client software." Explicit FTPS is the newer method of FTPS transfer and has generally overtaken implicit FTPS use, with the exception of "legacy" systems. When explicit FTPS is used, a traditional FTP connection is established on the same standard port as FTP. Once the connection is made (before login), a secure SSL connection is established via port 21.
