3. Detailed Content
3.1 Incident Description
In-depth Explanation:
This section provides a concise but comprehensive overview of the incident, outlining its nature and potential consequences.
Best Practices:
- Use clear and concise language.
- Avoid technical jargon where possible.
- Include a brief narrative explaining the incident.
Example:
"On [Date] at [Time], an unauthorized individual attempted to access the company's internal network through a phishing email. The email appeared to be from a legitimate vendor and contained a malicious link. The user clicked the link before realizing it was a phishing attempt. Fortunately, the security software detected and blocked the malicious link before any sensitive information was compromised."
Common Pitfalls:
- Vague or incomplete descriptions.
- Failure to explain the context of the incident.
- Using technical terminology that is not understood by all stakeholders.
3.2 Incident Details

This section assesses the potential or actual impact of the incident on the organization, including financial, reputational, and operational consequences.
Best Practices:
- Categorize the impact based on pre-defined levels (e.g., low, medium, high).
- Quantify the impact whenever possible (e.g., financial loss, data breaches, downtime).
- Consider the potential for long-term impacts beyond immediate consequences.
Example:
- Confidentiality: [Describe the potential or actual disclosure of confidential information, e.g., customer data, intellectual property].
- Integrity: [Describe the potential or actual alteration or corruption of data or systems].
- Availability: [Describe the potential or actual disruption of services, e.g., downtime, loss of access].
- Reputation: [Describe the potential or actual damage to the organization's reputation, e.g., negative media coverage, customer trust].
Common Pitfalls:
- Underestimating the impact of the incident.
- Failing to consider all potential consequences.
- Lack of clear and quantifiable metrics.
3.4 Evidence
In-depth Explanation:
This section documents any evidence collected or available related to the incident, including screenshots, logs, emails, and forensic reports.
Best Practices:
- Securely store all evidence in a designated location.
- Maintain a chain of custody for all evidence.
- Use forensic tools to collect and analyze evidence.
Example:
- Phishing Email: Screenshots of the phishing email, including the subject line, sender's address, and malicious link.
- System Logs: Logs from the affected system showing the attacker's actions.
- Network Logs: Logs from network devices showing suspicious traffic related to the incident.
- User Activity Logs: Logs from the user's account showing their actions before, during, and after the incident.
Common Pitfalls:
- Failure to collect or preserve evidence.
- Improper handling of evidence that compromises its integrity.
- Lack of documentation about the evidence collection process.
3.5 Actions Taken
In-depth Explanation:
This section lists the immediate steps taken to mitigate the incident, including actions taken to contain, isolate, and remediate the issue.
Best Practices:
- Document all actions taken, including the time of each action.
- Use clear and concise language to describe the actions.
- Refer to relevant procedures and guidelines.
Example:
- Containment: [Describe actions taken to prevent further damage, e.g., disconnecting affected systems, blocking attacker access, implementing temporary security measures].
- Isolation: [Describe actions taken to separate the affected systems from the rest of the network].
- Remediation: [Describe actions taken to repair the damage and restore the system, e.g., removing malware, restoring data, patching vulnerabilities].
- Communication: [Describe communication with relevant stakeholders, including management, IT staff, and affected users].
