Suricata 4.0.0-beta1 ready for testing!

Posted on | by inliniac

We are proud to announce that the first release for the upcoming Suricata 4.0.0-beta1 is ready for testing.

This release features our first experimental steps into using the Rust language for creating safer and easier to develop parsers. Inspired by Pierre Chiffliers talk at SuriCon 2016 (pdf). This initial integration does not yet include Pierre’s work, but this will likely change in the near future.
By compiling with –enable-rust you’ll get a basic NFSv3 parser and reimplementation of the DNS parser. Feedback on this is highly appreciated.

A major new feature is support for STARTTLS in SMTP and FTP. TLS sessions will now be logged in these cases. Decoding, logging and matching on TLS sertial numbers was also added. Great work by Mats Klepsland. Also for TLS, session resumption logging is now supported thanks to the work of Ray Ruvinskiy. TLS logging was improved by Paulo Pacheco.

Lots of new HTTP detection options were added to make matching on specific header fields easier and more efficient. New SSH keywords that are fast_pattern capable have also been added. For developers, this release makes extending the detection engine a lot easier.

A major TCP stream engine update is included. This should lead to better performance and less configuration, especially in IPS mode.

EVE is extended in several ways: in the case of encapsulated traffic both the inner and outer ip addresses and ports are logged. The ‘vars’ facility logs flowbits and other vars. This can also be used to extract data from the traffic using PCRE, and then log it. EVE can also be rotated based on time.

David Wharton has created a section in the documentation for rule writers who have a background in Snort. It documents changes that are relevant for writing rules.

Paulo Pacheco has been improving the Redis output performance.

Note that this release finally drops support for CentOS 5, and for libpcap 0.x with it.
