Analyze potential cybersecurity risks | Information Systems homework help

You are the information security manager (ISM) of a financial and  savings organization (NCU Financial Savings Bank, or NCU-FSB) with a  clientele base of 250,000 customers averaging 1.2 million transactions  per week. The IT infrastructure consists of 10 servers for each of the  three locations: five for local production and five for replication and  redundancy. After a recent vulnerability assessment performed by an  external firm, specific threats and vulnerabilities were identified and  needed to be addressed. The conceptual network diagram for NCU-FSB is  displayed in the Network Conceptual Diagram (attached)

The following findings were reported:

  • MAC address conflicts that need to be resolved between  telecommunications and network appliances (routers, switches, firewalls,  servers, etc…)
  • Security warnings coming from the proxy and email servers
  • Constant firewall alerts classified as high
  • Employee collusion in certain processes that can result in a significant financial loss to the organization
  • Inconsistencies in data transmissions
  • Attacks detected from external international sources caused by  multiple critical servers that have been compromised due to  vulnerabilities in the operating system, where the presence of  additional services, opened ports, additional dynamic link libraries  (DLLs), additional files and scripts added to the system partitions, and  critical data missing from the server issues were detected

As the newly hired ISM of the organization, you have been tasked by  the board of directors to analyze and layout a strategy to address risk  issues and what aspects or areas should be considered when performing a  security risk assessment. One of the first observations is the lack of  segregation of duties (SOD) to reduce any collusion, but you recognize  this could lead to an increase in the number of employees within your  team. Budgetary constraints are against the addition of employees in  your department.

Instructions:

For this assignment, you must write a two-column, two-page journal  article presenting the results of your analysis and initial data  discovery (eDiscovery) in which you briefly answer the following  questions:

  • What solutions can you employ to reduce or even eliminate the possibility of collusion in the financial organization?
  • How would you address the need to segregate duties (SOD) and rotate  tasks, for it is a requirement by laws applicable to financial and  savings institutions like Sarbanes Oxley (SOX) and Gramm Leach Bliley  Act (GLBA)?
  • What actions or changes in server setting and configuration must be made to avoid MAC address collision and server compromise?

A template for the journal formatting is available in the attachments (sample journal). Be sure to set all margins to 1-inch. Use single spacing and  12-point Times New Roman font.

You article must also include the following:

  • An introduction that addresses the essence of a security risk  assessment. In this introduction, you will explain and defend the  importance of having a risk management program in place, the main  elements of a risk program, and the benefits derived from incorporating  this strategy as part of the corporate security program.
  • Discussion of the primary threats enterprises are currently facing,  the impact, and a comprehensive analysis of how security must address  these threats, attacks, and vulnerabilities.
  • Different regulatory requirements that warrant a security risk analysis.
  • Taxonomy of risk elements for cyber-risk management as part of the  security risk analysis. Define the concept of taxonomy and its  importance as part of the risk assessment and management process.  Develop a table and relation diagram.
  • Information needed to initiate a security risk analysis—eDiscovery process flowchart and explanation.
  • A minimum of 3 scholarly references listed at the bottom of the paper.
  • Length: two-column, two-page journal article

The completed assignment should demonstrate thoughtful consideration  of the ideas and concepts that are presented in the course and provide  new thoughts and insights relating directly to this topic. Your response  should reflect graduate-level writing. Be sure to adhere to the Academic Integrity Policy. Proivide a plagiarism report
