SMS Firewall Screening for Fraudulent Source Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fraudulent SMS phishing attacks pose a significant threat to telecommunication networks, compromising private systems and resulting in financial losses and identity theft, with existing systems failing to effectively mitigate these risks.
Innovation Solution
A SMS firewall monitoring system that screens messages for fraudulent sources by comparing transmitting source data to stored data of potentially fraudulent sources, performing screening actions and transmitting notifications to security risk systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional message filtering systems are used, then some fraudulent messages can be blocked, but they fail to effectively mitigate SMS phishing attacks due to spoofing techniques
Solution Approach 1:
The system performs preliminary comparison of transmitting source data against stored potentially fraudulent source data before messages reach recipients. By proactively identifying and blocking messages from fraudulent sources at the network level before they can deceive users, the system prevents phishing attacks rather than merely filtering them after delivery.
Solution Approach 2:
The SMS firewall protocol acts as an intermediary between message senders and recipients, inserting a verification layer that compares transmitting source data against a database of potentially fraudulent sources. This intermediary mechanism blocks malicious messages while allowing legitimate ones to pass through, effectively mitigating phishing attacks without user intervention.
2Reliability
If comprehensive message screening is implemented across the network, then fraud protection improves, but system complexity increases
Solution Approach 1:
The SMS firewall protocol is designed as a universal screening mechanism that can be deployed across telecommunication networks to protect multiple recipients and organizations simultaneously. The same protocol and database of potentially fraudulent sources serve all message routing decisions, providing comprehensive security without requiring separate complex systems for each entity.
Solution Approach 2:
The system uses stored data copies of potentially fraudulent source information (phone numbers, message patterns, metadata) to compare against incoming messages. By maintaining and comparing against replicated databases of known fraudulent sources rather than analyzing each message in isolation, the system achieves comprehensive screening through efficient data matching.
Data Source
AI summary
Systems and methods receive a message screening subscription request to screen SMS messages from potentially fraudulent sources to reduce SMS phishing attacks, the messages to be screened by a telecommunications network via a SMS firewall protocol for a plurality of recipient telephone numbers. It is ascertained that a message is being routed to at least one telephone number of the plurality of recipient telephone numbers, and data of a transmitting source of a message is compared, using the SMS firewall protocol, to stored data of potentially fraudulent sources. Based on the source of the message matching a potentially fraudulent source of the potentially fraudulent sources, a screening action is performed for the message.
