Identify Threats and Vulnerabilities in an IT Infrastructure

Part 2

1. What are the differences between ZeNmap GUI (Nmap) and Nessus?

2. Which scanning application is better for performing a network discovery reconnaissance probing of an IP network infrastructure?

3. Which scanning application is better for performing a software vulnerability assessment with suggested remediation steps?

4. How many total scripts (i.e., test scans) does the Intense Scan using ZenMap GUI perform?

5. From the ZenMap GUI pdf report page 6, what ports and services are enabled on the Cisco Security Appliance device?

6. What is the source IP address of the Cisco Security Appliance device (refer to page 6 of the pdf report)?

7. How many IP hosts were identified in the Nessus® vulnerability scan? List them.

8. While Nessus provides suggestions for remediation steps, what else does Nessus provide that can help you assess the risk impact of the identified software vulnerability?

9. Are open ports necessarily a risk? Why or why not?

10. When you identify a known software vulnerability, where can you go to assess the risk impact of the software vulnerability?

11. If Nessus provides a pointer in the vulnerability assessment scan report to look up CVE-2009-3555 when using the CVE search listing, specify what this CVE is, what the potential exploits are, and assess the severity of the vulnerability.

12. Explain how the CVE search listing can be a tool for security practitioners and a tool for hackers.

13. What must an IT organization do to ensure that software updates and security patches are implemented timely?

14. What would you define in a vulnerability management policy for an organization?

15. Which tool should be used first if performing an ethical hacking penetration test and why?
