, You have just installed Nessus for auditing a network segment.
Which of the following Nessus scans would be BEST suited for an initial query of hosts on a network
segment?
A. Credentialed Patch Audit
B. Basic Network Scan
C. Bash Shellshock Detection
D. Advanced Dynamic Scan - Correct Answers: B. Basic Network Scan
Explanation
Basic Network Scan discovers all hosts on a network and performs queries to determine vulnerability
risks and threat vectors. It is the best answer here.
Bash Shellshock Detection is specific to a known subset of exploitable vulnerabilities, usually on Unix and
Linux-based operating systems. That means other operating systems would be mostly ignored, which is
not what we would prefer on an initial scan.
Credentialed Patch Audit only looks for patches that haven't been installed.
Advanced Dynamic Scan targets CVE ranges that might need to be addressed on a targeted host or
hosts. This is not what we want for a primary scan.
A security administrator wants to scan the company's network for vulnerabilities.
Which of these scanners is an open-source software developed from the Nessus codebase?
A. Qualys
B. Tenable
C. OpenVAS
D. nmap - Correct Answers: C. OpenVAS
