Questions and Answers

What does the unit "Introduction to security incidents" cover?

It covers the basic concepts of cyberincidents and incident management by reviewing its key areas, such as classifications, categories, levels of criticality, and a general understanding of the stages and principles of incident management according to the NIST model.

What are the three core principles of information security?

  • Confidentiality, Integrity, Security
  • Security, Integrity, Availability
  • Confidentiality, Availability, Trust
  • Confidentiality, Integrity, Availability (correct)
  • A Denial-of-Service (DoS) attack aims to gain access to a system.

    False

    What is a "Trojan horse" in the context of cybersecurity?

    <p>A &quot;Trojan horse&quot; is a type of malicious code disguised as legitimate software to trick users into installing it. Once installed, it can perform malicious actions, such as stealing data or granting remote access to attackers.</p> Signup and view all the answers

    Why is it crucial to keep offline copies of important documents related to incident response?

    <p>In case of a cyber incident, access to computer files might be compromised. Having physical backups ensures that critical information and plans remain readily accessible for incident management and mitigation.</p> Signup and view all the answers

    It's recommended to ensure that backup copies are closely linked to the primary system for easy retrieval.

    What is the primary objective of the "containment" stage of incident management?

    <p>To minimize the impact of a cyber incident and prevent further damage to the organization's systems and data.</p> Signup and view all the answers

    What is the most important aspect to consider when making decisions during incident containment?

    <p>The organization must have predetermined strategies and procedures in place for containing the incident. This helps to make decisions more efficient and effective, especially in high-pressure situations.</p> Signup and view all the answers

    Study Notes

    Topic 2.1 Introduction to Cybersecurity Incidents

    • Cybersecurity Incident Framework: The unit introduces core concepts of cybersecurity incidents and their management.
    • Incident Taxonomy: Defines key concepts, types, and classifications of cybersecurity incidents to establish a framework for efficient response. Crucially, it determines the level of criticality.
    • Incident Management: Details basic principles for managing incidents, covering the lifecycle from preparation to post-incident activities. This uses the NIST model as a reference. Key metrics for organizational maturity are also included.
    • Incident Response Centers (CERT-CSIRT-SOC): Introduces incident response hubs, explaining their role, capabilities, and divisions (proactive/reactive services). Organizational structures are highlighted.
    • Incident Action Procedures: Presents key procedures for managing incidents, notably emphasizing the preparatory phases in technology, operations, legal and communication aspects.
    • Information Exchange and Labeling: Displays fundamental information sources and tools, including threat intelligence platform MISP, and discusses standard formats for exchanging cybersecurity information and tagging incidents.

    Topic 2.2 Cybersecurity Incident Taxonomy

    • Definition of a Cybersecurity Incident: A cybersecurity incident is a compromise or violation of a firm's IT assets (information, services, infrastructure elements like servers, computers, networks, smartphones, etc.). This can encompass electrical/hardware failures, policy violations, and malicious activity (including disgruntled employees.)
    • Fundamental Security Principles: The consequence of a cybersecurity incident compromises fundamental security principles: confidentiality, integrity and availability of information.

    Topic 2.3 Cybersecurity Incident Management: Phases

    • Cybersecurity Event: A significant cybersecurity change that may impact organizational operations (mission, capabilities, reputation, etc.).
    • Cybersecurity Incident: One or more unexpected/undesirable cybersecurity events, potentially compromising organizational operations.
    • Incident Management: Comprehensive processes for preparing, detecting, reporting, evaluating, and responding to security incidents, while continuously improving the response plan.
