Card System Framework for Security Investigation Playbooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security analysts face challenges in organizing, documenting, and sharing large amounts of data during investigations, leading to inefficiencies in data retrieval and reuse, as well as a lack of documented history for other analysts to build upon.
Innovation Solution
A card system framework that organizes data in a reusable card format, allowing users to interactively explore details, document their research, and share findings, while playbooks guide users through investigations with predefined steps and questions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If security analysts manually organize and document large amounts of investigation data, then complete documentation is achieved, but time consumption and operational complexity increase significantly
Solution Approach 1:
The system pre-defines investigation playbooks with standardized procedures, data collection templates, and documentation structures before investigations begin. This allows analysts to simply follow predefined steps rather than creating documentation from scratch, significantly reducing time while maintaining completeness
Solution Approach 2:
The investigation process is divided into discrete, manageable steps within playbooks, each with specific documentation requirements. This segmentation allows analysts to document incrementally throughout the investigation rather than attempting to document everything at once, reducing time pressure and improving efficiency
2Loss of information
If security analysts create detailed documentation for each investigation, then research history is preserved, but the complexity of managing and retrieving data increases
Solution Approach 1:
The system implements a universal card-based data structure that can represent different types of investigation data (alerts, indicators, findings, evidence) using the same standardized format. This universality allows consistent organization and retrieval of diverse data types without increasing management complexity
Solution Approach 2:
The system introduces an intermediary layer of standardized data models and templates between the raw investigation data and the storage/retrieval system. This intermediary structure automatically organizes data according to predefined schemas, simplifying management while preserving complete research history
3Quantity of substance
If security data is organized in traditional formats, then data storage is achieved, but data reuse across different investigations is limited
Solution Approach 1:
The system creates reusable templates and patterns for common investigation scenarios, data structures, and analysis approaches. These can be copied and adapted across different investigations, allowing analysts to leverage previous work without manually recreating structures, thereby enhancing data reuse while maintaining storage capacity
Solution Approach 2:
The standardized card-based data structure is designed to be universally applicable across different investigation types and contexts. Each data element is structured to be independently reusable, allowing data to serve multiple purposes across different investigations and analytical scenarios
4Ease of operation
If security analysts work independently without structured guidance, then investigative flexibility is maintained, but investigation quality and continuity decrease
Solution Approach 1:
The system provides dynamic playbooks that adapt to the specific investigation context while maintaining structured guidance. The playbooks can be customized and modified based on emerging threats and investigative needs, preserving flexibility while ensuring quality through standardized procedures and checklists

AI summary
Examples disclosed herein relate to playbook-based security investigations using a card system framework. Some of the examples enable receiving an indication that a playbook is selected for investigating a security alert object, the playbook comprising a plurality of cards, wherein a first object definition associated with the security alert object comprises a parameter, and wherein the playbook inherits a value of the parameter from the first object definition; causing a first card from the playbook to be displayed on a user interface, the first card comprising a first content tile that describes the security alert object; and causing a second card from the playbook to be displayed on the user interface, the second card comprising a second content tile that describes a second object, wherein a second object definition associated with the second object comprises the parameter inherited from the first object definition.
