Structures, processes, and plans in place to counter and respond to potential attacks and to deal with the consequences of successful attacks

Introduction

To be proactive, organizations need to have structures, processes, and plans in place to counter and respond to potential attacks and to deal with the consequences of successful attacks. A suitable security management plan and well-defined security goals that support the overall goals of the organization can ensure a reasonable level of business continuity, even in the case of security incidents.

In any organization, the individuals on the IT staff must work together to support the security goals of the organization. These individuals play significant roles in detecting and preventing security incidents before they occur. In the case of successful attacks, security management professionals are tasked with acting quickly to mitigate the attack’s effects.

In this assessment, you will refer to the attached “Case Study” document, which contains details regarding a security incident at a small non-governmental organization (NGO). In part I of this task, you will analyze the security incident and provide specific examples and details from the case study to support your risk assessment. In part II, you will create a plan to effectively address the aftermath of the incident and manage the NGO’s ongoing security risks.

Part I: Incident Analysis and Response

A. Determine why the attack on Azumer Water’s infrastructure was successful, including two specific vulnerabilities that allowed the attack to occur. Provide details from the case study to support your claims.

B. Explain how Azumer Water’s operations and data have been compromised in the following areas:

confidentiality, integrity, and availability
PII (personally identifiable information)

For two of the claims, support your analysis using an industry-standard framework such as NIST or ISO 27002.

C. Identify a federal regulation this NGO violated, providing a specific example from the case study as evidence of Azumer Water’s noncompliance.

D. Recommend two immediate steps to mitigate the impact of the incident, using specific examples from the case study to justify how these steps would mitigate the impact.

E. Explain how having an incident response plan in place will benefit Azumer Water, using details from the case study to support your explanation.

Part II: Risk Assessment and Management

F. Discuss two processes to increase information assurance levels within the organization and bring Azumer Water into compliance with the violated federal regulation identified in part C.

G. Recommend two technical solutions to counter the remaining effects of the attack in the case study and to prevent future attacks.

H. Recommend an organizational structure for IT and security management, including a logical delineation of roles and adequate coverage of responsibilities, to support the efficient discovery and mitigation of future incidents.

Sample Answer

This is an excellent assessment task that requires applying cybersecurity principles to a realistic scenario. While I don’t have access to the specific “Case Study” document you mentioned, I can provide a comprehensive framework and example responses that demonstrate how to approach each part of this assessment. You can adapt this framework to the specific details in your case study.

Let’s break down each section with detailed guidance and examples:

Part I: Incident Analysis and Response

A. Determine why the attack on Azumer Water’s infrastructure was successful, including two specific vulnerabilities.

To answer this, you’ll need to identify technical and procedural weaknesses from the case study. Here’s a framework for your response:

Example Response:

The attack on Azumer Water’s infrastructure was successful due to several critical vulnerabilities that created an exploitable attack surface. Two specific vulnerabilities that allowed the attack to occur were:

Lack of Multi-Factor Authentication (MFA): The case study likely indicates that employees accessed critical systems (such as the SCADA system or customer database) using only a username and password. This is a significant vulnerability. Attackers could have obtained these credentials through methods like phishing (which might be mentioned in the case study) or by exploiting weak password policies. Without MFA, stolen credentials are sufficient to gain unauthorized access. For example, if the case study mentions an employee clicking a phishing link and entering their credentials, the lack of MFA directly enabled the attackers to use those credentials to access sensitive systems.

Unpatched or Outdated Software: The case study may reference specific systems or software that were not kept up-to-date. For instance, it might state that the organization’s Industrial Control Systems (ICS) or web server were running on outdated operating systems or applications with known vulnerabilities. Attackers actively scan for and exploit these known vulnerabilities. A specific example could be the attackers using a well-documented exploit (like EternalBlue for unpatched Windows systems) to gain initial access or escalate privileges within the network, allowing them to move laterally and reach critical operational technology (OT).

(Remember to replace these examples with specific details from your case study, such as the name of a system, the type of phishing email, or the specific consequence of the unpatched software.)

B. Explain how Azumer Water’s operations and data have been compromised.

You need to analyze the impact on the CIA triad and PII. Use a framework like NIST or ISO 27002 to structure your analysis.

Example Response:

The security incident has significantly compromised Azumer Water’s operations and data across multiple domains:

Confidentiality: The confidentiality of data has been breached as attackers gained unauthorized access to sensitive information. This likely includes internal communications, operational procedures, and customer data.
Integrity: The integrity of data and systems has been compromised. The attackers may have altered critical data, such as water quality testing results or customer billing information. More critically, they may have modified the logic or settings within the SCADA system, which controls the physical water treatment and distribution processes. This could lead to incorrect chemical dosing or improper flow rates, posing a direct public health risk.
Availability: The availability of systems has been impacted. The attack likely resulted in a Denial-of-Service (DoS) condition, either intentionally by the attackers (e.g., using ransomware to encrypt servers) or unintentionally as a side effect of their activities (e.g., crashing systems during exploitation). This disruption would prevent Azumer Water from monitoring its infrastructure, processing customer payments, or even safely operating the water treatment plant.
