Your boss wants you to draft a two- to three-page vulnerability process and assessment memorandum addressing the main points of a VM process for Me

 

Your boss wants you to draft a two- to three-page vulnerability process and assessment memorandum addressing the main points of a VM process for Mercury USA. You will cover the main elements of a vulnerability management process, tailored to Mercury USA’s business in the transportation sector, evaluate the OpenVAS scanning tool, and provide recommendations for mitigating the vulnerabilities found within the OpenVAS report.

The third-party pen tester used the free tool Open Vulnerability Assessment Scanner (OpenVAS) to scan Mercury USA’s network. Review the report from the OpenVAS Scan.

As you review the scan, consider some important points from Lesson 5:

  • Priority
  • Difficulty of implementation
  • Communication/change control
  • Inhibitors to remediation
    • MOUs
    • SLAs
    • Business process interruption
    • Degrading functionality

2.1.4 Low general/tcp

Low (CVSS: 2.6) NVT: TCP timestamps

Summary The remote host implements TCP timestamps and therefore allows to compute the uptime.

Vulnerability Detection Result It was detected that the host implements RFC1323. The following timestamps were retrieved with a delay of 1 seconds in-between: Packet 1: 470603 Packet 2: 471709

Impact A side e˙ect of this feature is that the uptime of the remote host can sometimes be computed.

Solution Solution type: Mitigation To disable TCP timestamps on linux add the line ‘net.ipv4.tcp_timestamps = 0’ to /etc/sysctl.conf. Execute ‘sysctl -p’ to apply the settings at runtime. To disable TCP timestamps on Windows execute ‘netsh int tcp set global timestamps=disabled’ Starting with Windows Server 2008 and Vista, the timestamp can not be completely disabled. The default behavior of the TCP/IP stack on this Systems is to not use the Timestamp options when initiating TCP connections, but use them if the TCP peer that is initiating communication includes them in their synchronize (SYN) segment. See the references for more information.

A˙ected Software/OS TCP/IPv4 implementations that implement RFC1323.

Vulnerability Insight The remote host implements TCP timestamps, as de˝ned by RFC1323.

Vulnerability Detection Method Special IP packets are forged and sent with a little delay in between to the target IP. The responses are searched for a timestamps. If found, the timestamps are reported. Details: TCP timestamps OID:1.3.6.1.4.1.25623.1.0.80091 Version used: $Revision: 14310 $

[Your name and course number/section]

[Opening Salutation]:

Overview

In this section, provide a brief overview to establish the purpose of your memorandum. You should introduce the topics in Parts 1, 2, and 3, below. Remember that you are writing to your immediate boss to help her address the CEO’s concerns over recent cybersecurity attacks against the transportation sector. Additionally, your boss has provided you with the results of a recent pen testing engagement performed by a third party on behalf of Mercury USA.

Part 1: Vulnerability Management (VM) Process Recommendation

In this section, present a recommended VM process for Mercury USA. Highlight the major VM process components as you learned in your studies. Explain how your recommendation meets the business needs of Mercury USA. Consider the transportation sector and the overall scenario in context. The text and questions below represent specifics to focus on while writing the memorandum. Do not include the specific text of the questions in your final submission.

· What are the main elements of a VM process, tailored to Mercury USA and the transportation sector?

· How will you plan for and define the scope of a VM process?

· How will you identify the assets involved?

· How will you scan and assess vulnerabilities?

· What is/are the industry standard scanning tools? Support your findings.

· What frequency of scanning do you recommend and why?

· How will you report the results of scanning and recommended countermeasures?

Part 2: Vulnerability Scanning Tool Evaluation and Recommendations

After performing an analysis of the vulnerability report provided by the third-party penetration testers, present your evaluation of the tool and your recommendations here. The text and questions below represent the specifics to focus on while writing your memorandum. Do not include the specific text of the questions in your final submission.

· Identify the scanner used to produce the report. Is the tool open source or commercial? Do you consider the tool to be industry standard?

· What are some advantages to using the tool? Disadvantages?

· What is your overall impression of the tool’s output?

· Does the tool provide enough reporting detail for you as the analyst to focus on the correct vulnerabilities? Can you appropriately discern the most critical vulnerabilities?

· Do you think mitigations for the vulnerabilities are adequately covered in the report?

· Do you think the reports are suitable for management? Explain why or why not.

· Would you distribute the report automatically? Explain why or why not.

· Would you recommend that Mercury USA use the tool? Explain why or why not.

Part 3: Business Case Example

In this section, provide an example of what could happen if Mercury USA does not implement your recommendations for a VM process (e.g., data exfiltration, hacker intrusions, ransomware, etc.). The text and questions below represent the specifics to focus on while writing your memorandum. Do not include the specific text of the questions in your final submission.

· What are some of the outcomes to the business if your example occurred?

· How does your recommended VM process address the example you used?

· For the tool you evaluated in Part 2 above, do you think the tool will be adequate? Why or why not?

Closing

In this section, summarize the main points of your argument for a VM process, tool evaluation, and use the case example to support your recommendations. Keep in mind that you are addressing the CEO’s concerns over recent cybersecurity attacks against the transportation sector and how you can help increase Mercury USA’s overall security posture to protect the organization against attacks, breaches, and data loss.
