Incident Response Masterclass

The lesson Introduction to Incident Response: Overview of Incident Response Frameworks is a crucial component of the Incident Response Masterclass: Navigate and Resolve Cyber Threats with Digital Forensics Expertise course. This lesson begins by examining the basic definition of incident response and its vital role in cyber security. We delve into the objectives of an incident response team and their organizational functions. Students will gain an overview of two leading frameworks: the National Institute of Standards and Technology (NIST) framework and the SANS Institute’s incident response cycle, emphasizing their relevance in digital forensics.

The lesson explores the six phases of incident response: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. The importance of the preparation phase is underscored for establishing a sturdy incident response plan. The identification phase is illustrated with techniques used to detect cyber incidents and strategies for effective containment to limit damage. We explain eradication methods to remove root causes and discuss recovery processes to restore normal operations post-incident. The lesson highlights the significance of the 'Lessons Learned' phase for improving future response efforts and includes an analysis of digital forensics in incident investigation.

Comparisons are made between the NIST and SANS frameworks, focusing on their differences and similarities. The session also outlines the essential skills and roles in an incident response team and the paramount importance of communication and collaboration among team members. Students will explore the common challenges encountered during incident response and strategies to tackle these hurdles. The lesson also addresses the legal and regulatory implications associated with incident response and data breaches, stressing the integration of threat intelligence to enhance response effectiveness.

Finally, the role of automated tools and technologies in supporting incident response efforts is evaluated, emphasizing the importance of continuous improvement and adaptation given the evolving nature of threats. This comprehensive exploration equips students with the foundational understanding necessary to effectively navigate and resolve cyber threats using incident response frameworks.
