Fast Packet Processing

Fast Packet Processing (FPP) is a technique used in cybersecurity to analyze and process network traffic in real-time. FPP involves analyzing and processing packets of data as they are transmitted over a network, allowing for the detection and prevention of security threats in real-time. Open source FPP tools are tools that are developed and maintained by a community of volunteers, rather than a commercial organization. Some popular open source FPP tools include Suricata, Bro, and Snort. These tools are often used by cybersecurity professionals and network administrators to monitor network traffic and identify potential security threats, such as malware infections, unauthorized access attempts, and network anomalies. By providing real-time monitoring and analysis of network traffic, open source FPP tools can help organizations to quickly identify and respond to potential security incidents.
