The evolution of system introspection from BPF to Wireshark to Falco | The Official Wireshark Blog

Falco, an open source innovation, was conceived with the vision of crafting a flexible and robust rules engine atop the Sysdig libraries. This initiative aimed to furnish a potent tool for the detection of aberrant behaviors and intrusions within modern applications, akin to the Snort paradigm but tailored to the realm of system calls and finely tuned for cloud environments. Nevertheless, it’s important to recognize that Falco and Wireshark represent distinct facets of this evolutionary process. Falco offers ongoing surveillance akin to Snort, while Wireshark specializes in interactive endpoint network traffic analysis. Introduction 🔗Part of this journey has been the emergence of cloud-native apps. From the early days of BPF (Berkley Packet Filter) and libpcap (a portable C/C++ library for network traffic capture), which laid the foundation for network packet analysis, to the familiar graphical user interface of Wireshark, our understanding of network data has undergone profound changes. This article embarks on a journey through this transformation, shedding light on how tcpdump and libpcap sparked an explosion of packet-based analysis and runtime security tools exemplified by Wireshark and Snort. Wireshark, Snort, Nmap, Kismet, ngrep, and a bunch of other tools started at around the same time and are all evolutionary branches of tcpdump and libpcap.
