Spicy: Creating Robust Parsers for Dissecting Network Protocols and Files, Easily!

Speaker: Robin Sommer

Abstract

This talk presents Spicy, a new parser generator that emits robust & efficient C++ code for dissecting network data. Spicy is a bit like a “yacc for protocols”, but it’s much more than that: it’s a self-contained scripting environment that lets developers define syntax and logic for their input format using attributed, stateful grammars.

The Spicy toolchain then turns those grammars into C++ parsing code that any host application can drive. We have integrated Spicy into Zeek, a widely deployed BSD-licensed network security monitor; it will become part of the next Zeek release.

We will demonstrate how Spicy enables parser developers to dynamically add production-ready support for new protocols and file formats to Zeek without having to write a single line of C++ code themselves.
