[Solved] Evaluating Incident Response Operations

Assignment Prompt & Instructions

Scenario
You are working as a cybersecurity analyst at FinSecure Corp, a midsize financial organization. A recent malware incident has prompted a comprehensive review of the company's incident response procedures and network security architecture. FinSecure operates primarily in an on-premises environment with some remote users connecting via VPN. As part of this review, you have been asked to evaluate how the incident was handled, assess the network architecture for vulnerabilities, and recommend adjustments to firewall and intrusion detection system (IDS) configurations to prevent future threats.
Refer to the attached "Incident and Network Security Artifacts" in the Supporting Documents section.
Requirements
A.  Evaluate the organization's response to the security incident by doing the following:
1.  Identify **three** actions the organization took in response to the incident.
2.  Evaluate the effectiveness of _each_ of the **three** actions from part A1 using a recognized incident response framework (e.g., NIST, SANS, ISO).
3.  Recommend **two** improvements to the organization’s incident response procedure that would strengthen detection, containment, or recovery efforts in future incidents, and justify why _each_ recommendation would improve the organization’s incident response effectiveness.
B.  Analyze the provided network architecture diagram and firewall configuration by doing the following:
1.  Identify **three** vulnerabilities, design flaws, or misconfigurations that create or enable security risks in the network setup.
2.  Recommend a secure network design or remediation strategy for _each_ of the **three** identified issues in part B1, and justify why _each_ recommendation would improve network security.
3.  Explain how _each_ recommendation in part B2 would improve the network's ability to resist or detect threats and support the confidentiality, integrity, or availability (CIA) of information.
C.  Review the existing firewall and IDS rule sets by doing the following:
1.  Identify **two** weaknesses or gaps in the existing firewall or IDS rule sets that create or could allow security risks.
2.  Explain how _each_ weakness or gap identified in part C1 could allow known threats to exploit the network. Support your explanation with evidence from the provided artifacts.
3.  Propose **two** updated or additional firewall or IDS rules to address the weaknesses identified in part C1, and justify how _each_ proposed rule would improve network security and help defend against the threats discussed in part C2.
D.  Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or summarized.
E.  Demonstrate professional communication in the content and presentation of your submission.
