Bro Network Security Monitor

Much of Bro’s capabilities originate in academic research projects, with results often published at top-tier conferences. Bro supports a wide range of analyses through its scripting language. Yet even without further customization it comes with a powerful set of features.

  • Feature

    • Runs on commodity hardware on standard UNIX-style systems (including Linux, FreeBSD, and MacOS).
    • Fully passive traffic analysis off a network tap or monitoring port.
    • Standard libpcap interface for capturing packets.
    • Real-time and offline analysis.
    • Cluster-support for large-scale deployments.
    • Unified management framework for operating both standalone and cluster setups.
    • Open-source under a BSD license.
    • Support for many application-layer protocols (including DNS, FTP, HTTP, IRC, SMTP, SSH, SSL).
    • Default output to well-structured ASCII logs.
    • Real-time integration of external input into analyses. Live database input in preparation.
    • External C library for exchanging Bro events with external programs. Comes with Perl, Python, and Ruby bindings.
