Synchronized Email Threat Inspection for Targeted Attack Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing email security solutions are inadequate in effectively blocking and responding to targeted email attacks, which pose significant risks through sophisticated methods like malware and social engineering, leading to security vulnerabilities in both incoming and outgoing emails.
Innovation Solution
An email security system that synchronizes threat information from inbound and outbound emails, performing a targeted email security threat inspection and response process, including spam, malware, and social engineering threat inspections, to provide comprehensive protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive targeted email security threat inspection is performed on both inbound and outbound mails, then email security protection is improved, but system complexity increases
Solution Approach 1:
The email security system is divided into separate inspection modules for inbound mails and outbound mails, each handling specific threat types. The threat inspection unit processes different categories of threats (spam, malware, social engineering, information leakage) through dedicated inspection pathways, reducing overall system complexity while maintaining comprehensive protection
Solution Approach 2:
The threat information synchronization mechanism creates a unified security database that serves both inbound and outbound email inspections. This multi-functional approach allows the same threat intelligence to be applied across different email directions and threat types, improving security effectiveness without proportionally increasing system complexity
2Measurement precision
If threat information is synchronized between inbound and outbound email inspections, then detection accuracy is improved, but processing time increases
Solution Approach 1:
The system performs threat information synchronization in advance by maintaining an updated threat intelligence database from previous inbound and outbound inspections. This pre-computed threat information is readily available when new emails require inspection, eliminating the need for real-time cross-referencing and reducing processing delays
Solution Approach 2:
The system replaces complex real-time mechanical synchronization processes with a database-driven approach using stored threat intelligence. Instead of continuously coordinating between inspection processes, the system uses pre-stored threat information from the synchronization database, significantly reducing processing time while maintaining detection accuracy
3Adaptability or versatility
If multiple types of threat inspections are performed (spam, malware, social engineering, information leakage), then security coverage is improved, but inspection complexity increases
Solution Approach 1:
The inspection system is divided into specialized modules for different threat types: spam inspection, malware inspection, social engineering inspection, and information leakage inspection. Each module focuses on specific indicators and methodologies, making individual inspections simpler while collectively providing comprehensive security coverage
Solution Approach 2:
The threat information synchronization database acts as an intermediary that consolidates threat intelligence from multiple inspection types. This centralized repository allows different inspection modules to access unified threat data without direct complex interactions between them, simplifying the overall inspection architecture while maintaining versatile security coverage

AI summary
An operation method of an email security system comprises the steps of: configuring security threat information synchronization data by synchronizing targeted email security threat information configured by performing a targeted email security threat inspection on an inbound mail with targeted email security threat information configured by performing a targeted email security threat inspection on an outbound mail; performing a targeted email security threat inspection corresponding to a new inbound mail or a new outbound mail using the security threat information synchronization data; and performing a targeted email security threat response process according to the targeted email security threat inspection of the new inbound mail or the new outbound mail.
