Topsec Full Traffic Threat Traceability System by Topsec Network Security is a high-performance platform designed for collecting, storing, and analyzing all network traffic. It offers comprehensive data retention, session analysis, protocol parsing, communication analysis, and statistical analysis. It deeply analyzes data packets while capturing traffic, linking the results with traffic data for future retrieval and analysis. It is capable of storing all data traffic in PCAP format, capturing real-time traffic 24/7, ensuring no data is missed, and providing legally valid traffic session records for user access. It analyzes all fields in traffic for relationship mapping, clearly displaying source-destination relationships and session details to accurately trace data flow in the network. It utilizes Elasticsearch technology for rapid data retrieval, enabling queries on millions of data points in seconds. The system includes a view retrieval module and tagging feature for efficient traffic backtracking. The most common deployment method is bypass mirroring, which mirrors bidirectional network traffic from target network switches to collect all network communication data without altering the existing network topology. It allows for flexible deployment to meet compliance requirements without changing network structure, allowing for full traffic retention and access to original data packets, helping users comply with security regulations and reducing legal and political risks from network attacks. It provides complete traceability and forensics through full traffic retention for comprehensive retrospective analysis, extracting legally effective evidence. During the HW period, it enables timely detection of attack threats, tracing complete data packets, and improving network protection scores. Efficient retrieval and precise localization using over twenty search mechanisms quickly find specific attack packets in massive data, displaying payload content, accurately locating issues, and further analyzing and controlling impact scope to mitigate losses. Complete recording of network transmission provides data support for security incident investigation and forensics.
