Endpoint Agent for Email Threat Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cyber defense systems, including firewalls and antivirus methods, are insufficient in addressing the evolving nature of cyber threats, particularly those originating from or associated with email systems.
Innovation Solution
A cyber defense system incorporating an endpoint agent extension with multiple modules and machine learning models that integrates with email client applications to detect and respond autonomously to email threats by analyzing user behavior and email activity, preventing data exfiltration, and enforcing security policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional firewalls and antivirus methods are used, then basic security protection is provided, but they are insufficient against evolving email-based cyber threats
Solution Approach 1:
The system dynamically adapts to evolving threats by continuously learning from new email patterns and threat behaviors. The machine learning models are updated in real-time to recognize emerging threat types, allowing the security system to maintain effectiveness against evolving email-based cyber threats without requiring manual reconfiguration of traditional security rules.
Solution Approach 2:
The cyber defense system performs self-analysis and self-protection by autonomously evaluating email content, attachments, and metadata using machine learning algorithms. The system automatically identifies and blocks threats without human intervention, and continuously improves its detection capabilities by learning from analyzed threat patterns, making the security system both adaptive and self-sufficient.
2Speed
If autonomous actions are taken automatically by the system, then response time is reduced, but human control and verification are diminished
Solution Approach 1:
The system implements a feedback mechanism where autonomous actions taken against threats are monitored and evaluated. The results of these autonomous responses are fed back into the machine learning models, allowing the system to learn from its decisions and improve future autonomous actions while maintaining accountability through logged feedback loops that can be reviewed by security personnel.
Solution Approach 2:
The system performs preliminary analysis and classification of emails using machine learning models before taking autonomous actions. This preliminary evaluation prepares the system to respond quickly to confirmed threats while maintaining a record of the analysis process, allowing human operators to review decisions if needed while still benefiting from rapid automated response to clear threats.

AI summary
An endpoint agent extension of a cyber defense system for email that includes modules and machine learning models. An integration module integrates with an email client application to detect email cyber threats in emails in the email client application as well as regulate emails. An action module interfaces with the email client application to direct autonomous actions against an outbound email and/or its files when a cyber threat module determines the email and/or its files (a) to be a data exfiltration threat, (b) to be both malicious and anomalous behavior as compared to a user's modeled email behavior, and (c) any combination of these. The autonomous actions can include actions of logging a user off the email client application, preventing the sending of the email, stripping the attached files and/or disabling the link to the files from the email, and sending a notification to cyber security personnel regarding the email.
