 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 incident response, unsuccessful scans and probes are typically considered a low severity level. This is because they often indicate an attempted reconnaissance rather than a successful breach or compromise. These activities are usually automated and widespread, affecting many networks, not just the targeted one. They are often the preliminary steps of an attack, trying to find vulnerabilities but not yet exploiting them. Therefore, while they should be monitored and logged, they do not usually signify an immediate threat to the network’s integrity or the confidentiality of the data.

References: The EC-Council’s Certified Network Defender (C|ND) program emphasizes a defense-in-depth security strategy, which includes continuous threat monitoring and incident response. The program outlines that not all incidents require the same level of response, and categorizing the severity of incidents is crucial for effective prioritization and resource allocation1.

Stephanie is working on ensuring data integrity for her company’s email communications. Data integrity refers to the assurance that data has not been altered or tampered with during transit. By setting up encryption, Stephanie is ensuring confidentiality, which protects the contents of the email from being read by unauthorized parties. However, to ensure that the emails have not been modified, she is implementing digital signatures. Digital signatures provide a means to verify the authenticity of the sender and to ensure that the message has not been changed, which directly relates to the concept of data integrity in cybersecurity.
