 In the context of incident response methodology, the last step is typically referred to as ‘Post-Incident Activity’ or ‘Lessons Learned’. This step involves reviewing the incident to understand what happened, how it was handled, and how similar incidents can be prevented or mitigated in the future. It’s a critical phase where the organization can improve its security posture and response strategies. The follow-up step ensures that any residual risk is addressed, and that all documentation is completed. It also provides an opportunity for the incident response team to reflect on their actions and improve the incident handling plan for future responses.

References: The importance of the follow-up step as the last phase in the incident response methodology is supported by well-respected frameworks developed by NIST and SANS, which outline ‘Post-Incident Activity’ or ‘Lessons Learned’ as the final step123. These steps align with the objectives and documents of the EC-Council’s Certified Network Defender (CND) program.

 In the context of containerization, setting resource limits is crucial for ensuring that applications do not consume more than their fair share of system resources. Michelle can limit a container to use only 2 CPUs by using the --cpus flag when running a container. This flag allows the user to specify the amount of CPU the container is limited to use. For example, --cpus="2" would restrict the container to using no more than two CPU cores.

References: This information is based on standard practices for managing Docker containers and their resources. The --cpus flag is a well-documented feature in Docker’s command-line interface for controlling CPU usage1.

Indicators of attack (IoA) provide information about the attacker's intent, end goals, and the actions they take to execute an attack. IoAs help identify the methods and behaviors an attacker uses during the attack lifecycle. Unlike Indicators of Compromise (IoCs), which are used to detect evidence of a breach, IoAs are proactive and help in identifying and preventing potential attacks before they occur by analyzing the patterns and tactics used by attackers.

• Key risk indicators: Metrics used to signal increased risk exposure.
• Indicators of compromise: Artifacts observed on a network or in an operating system that with high confidence indicate a computer intrusion.
• Indicators of exposure: Data points or signals that reveal vulnerabilities or weaknesses that could be exploited.
