Attack Kill Chain Generation for Threat Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer security products fail to effectively leverage information from security reports and data across multiple diverse security products, leading to a lack of holistic view of attack campaigns, inadequate remediation of vulnerabilities, and absence of automated end-to-end validation and remediation cycles.
Innovation Solution
A method for generating an attack kill chain through receiving and mapping security events from multiple security operations to an attack repository, determining attack execution operations, sequencing them into a kill chain, and generating a visual representation for threat analysis and remediation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If security reports from multiple security products are analyzed in isolation, then individual security events can be detected, but a holistic view of attack campaigns cannot be achieved
Solution Approach 1:
The patent combines security events from multiple diverse security products into a unified attack kill chain representation. By merging data from antivirus, web application firewalls, intrusion prevention systems, and other security products, the system creates a comprehensive view of attack campaigns that individual products cannot provide alone.
Solution Approach 2:
The attack kill chain framework serves as a universal structure that can accommodate and integrate events from various types of security products. This multi-functional approach allows different security products with different event formats to be unified under a common analytical model.
2Reliability
If users remediate only highly severe vulnerabilities, then critical security risks are addressed, but weakly protected assets remain vulnerable without remediation
Solution Approach 1:
The system applies different levels of attention and remediation priority to different parts of the attack kill chain. Critical vulnerabilities that enable major attack steps receive higher priority remediation, while weaker protection points are identified and addressed with appropriate remediation strategies, creating a differentiated but comprehensive remediation approach.
Solution Approach 2:
By visualizing the complete attack kill chain, the system enables preliminary identification of weakly protected assets before attackers can exploit them. Security teams can proactively remediate vulnerabilities at various stages of the kill chain, preventing attacks before they reach critical systems.
3Extent of automation
If automated end-to-end validation and remediation cycles are not implemented, then manual security processes can be maintained, but feedback loops between security controls and remediation are absent
Solution Approach 1:
The system implements automated feedback loops where security events are continuously monitored, analyzed, and fed back into the remediation process. The attack kill chain visualization provides real-time feedback on security posture, enabling automated validation of remediation effectiveness and triggering of additional remediation actions when needed.
Solution Approach 2:
The automated system performs validation and remediation cycles without requiring constant manual intervention. Security controls automatically detect attacks, validate remediation effectiveness, and trigger appropriate responses, enabling the security infrastructure to serve itself in maintaining security posture.

AI summary
The present disclosure relates to methods, systems, and computer program products for generating an attack kill chain for threat analysis. The method comprises receiving a first security event captured by a first security operation associated with a computing device, and receiving a second security event captured by a second security operation associated with the computing device. The first security event and the second security event are associated with an attack campaign. The method further comprises mapping the first security event to first security data in an attack repository, and mapping the second security event to second security data in the attack repository. The method also comprises determining based on the mapping, one or more attack execution operations for executing the attack campaign associated with the first security event and the second security event. Additionally, the method sequences the one or more attack execution operations to form an attack kill chain.
