Scenario and Your Role
Information security incidents are stressful events for security practitioners. Inevitably, you will be faced with responding to an incident at some point in your career. Imagine that you discover that your organization’s network has been hacked. Indicators of compromise (IoC) include known hacking tools, modified file permissions, and multiple connections to an unknown network.
Root cause analysis shows that the attackers gained access to the network through the demilitarized zone (DMZ) from a compromised web server. A contributing factor in this attack is that the intrusion detection system (IDS) was misconfigured.
You must prepare a report on the incident for the CISO.
Requirements
Continue working in the same document; simply start your report on a new page with an appropriate heading.
In your report, address the following:
Outline an incident response plan for this type of attack.
Describe the concepts and strategies you would include in this plan.
Explain the purpose of a baseline analysis in an incident response plan.
Explain how you will test your incident response plan.
