Assignment 3: Incident Response And Strategic Decisions

Assignment 3 Incident Response Ir Strategic Decisions

Suppose that you have been alerted of a potential incident involving a suspected worm spreading via buffer overflow techniques, compromising Microsoft IIS Web servers. As the IR Team leader, it is your responsibility to determine the next steps. Write a two to three (2-3) page paper in which you: Explain in detail the initial steps that would need to be made by you and the IR team in order to respond to this potential incident. Construct a process-flow diagram that illustrates the process of determining the incident containment strategy that would be used in this scenario, and identify which containment strategy would be appropriate in this case, through the use of graphical tools in Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length. Construct a process flow diagram to illustrate the process(es) for determining if / when notification of the incident should be relayed to upper management, and explain how those communications should be structured and relayed through the use of graphical tools in Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length. Detail the incident recovery processes for the resolution of this incident. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources. Your assignment must follow these formatting requirements: Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The detection of a worm leveraging buffer overflow techniques to compromise Microsoft IIS Web servers necessitates a swift and strategic incident response. As the Incident Response (IR) team leader, the priority is to contain the threat while minimizing operational disruption. The initial steps involve establishing a clear incident scope, gathering relevant intelligence, and coordinating an immediate response. The IR team must first verify the alert through preliminary analysis, including checking system logs, IIS server activity, and network traffic for signs of exploitation. This verification step prevents false positives and ensures that efforts are appropriately directed.

Following confirmation of the incident, the team should implement immediate containment measures. These include isolating affected servers by disconnecting them from the network to prevent further spread, applying patches or updates to address known vulnerabilities, and disabling compromised accounts or services. During this phase, it is also essential to preserve forensic evidence by creating image copies of impacted systems and maintaining logs for later analysis.

Communication is vital throughout this process. Establishing a communication plan that involves informing upper management when certain thresholds of compromise are reached is crucial. A process-flow diagram can aid in visualizing decision points such as: has the incident been verified? Is the containment adequate? Is escalation necessary? These steps determine the timing and manner of notifying upper management, enabling structured and effective communication channels. Typically, initial reporting occurs once verification confirms a credible threat, followed by regular updates depending on the incident progression.

After containment, the focus shifts to incident eradication and recovery. Eradication involves removing the worm, patching vulnerabilities, and ensuring the system is clean. Recovery includes restoring services from clean backups, validating system integrity, and monitoring for any signs of residual malicious activity. It is essential to perform post-incident analysis, documenting lessons learned to improve future response strategies. Implementing these steps systematically helps ensure an effective resolution while maintaining organizational resilience.
