About Suricata

Suricata is a high performance Network Threat Detection, IDS, IPS and Network Security Monitoring engine. Open Source and owned by a community run non-profit foundation, the Open Information Security Foundation (OISF). Suricata is developed by the OISF, its supporting vendors and the community.

Github repository move

Ever since we’ve used github for Suricata development we’ve used Victors personal repository at inliniac/suricata as the main repository. As of today this has been changed.

The new repository location is OISF/suricata, which lives in the OISF organization at github.

It is a move of Victors original repo, so the existing open pull requests moved to OISF/suricata. Existing URLs should still work, as they are automatically redirected to the OISF/suricata repository.

Other than it looking better and more professional, this move as the advantage of the use of github teams we define in the OISF organization. This means it’s going to be easier to assign reviews to team members and outside contributors. We’ll add regular contributors as ‘outside collaborators’ so PRs can be assigned to them for review.

Like with the personal repository previously at inliniac/suricata, Victor remains the only one with rights to pushing to the official branches (master and master-z.y.x). However in his absence the rest of the team can create emergency branches and releases.

In the coming weeks we’ll try to update all existing documentation references to inliniac/suricata.

Please let us know if there are any unexpected issues from this move.

Rust and Suricata

In the newly released Suricata 4.0, one of the major new features is integration of Rust. In the words of the Rust Language project, “Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.”

For those of you who were at SuriCon DC, the topic of Rust isn’t new. Pierre Chiffliers’  talk ‘Securing Security Tools’ described why switching existing C/C++ tools to partly use Rust language parsers makes sense. See his slides here: pdf. After his talk, we have started looking into the proof of concept proposed by Pierre.

Rust was new to us so the process involved learning the language.

Major Components

  1. rust language: a safe systems programming language that compiles to native code and can be linked into a C program
  2. nom: a rust macro parser generator
  3. suricata – rust layer: connection between the rust code and the Suricata API’s

Rust Usage in Suricata

Rust parsers might be used for many things:

  • simple header parsers where we’d use a rust/nom parser for a header like DNS
  • specific data types, I’m thinking mostly about ASN.1 and mime here as those are notorious for vulnerabilities
  • full application layer parsing and logging in Suricata

Experiment

After the initial testing and playing by Jason Ish and Victor Julien, we have decided to move forward with Rust. However, as the language is young and our understanding of it is even younger, we will consider it experimental at first.

The experimental phase will have to teach us a couple of things:

  1. how does it work wrt stability and performance
  2. what does it take to support Suricata with Rust extensions
  3. how mature is the Rust ecosystem

Depending on our experiences we’re planning to take between 6 and 12 months for this experimental phase. As we’re considering this experimental we’re going to be quite liberal with regards to updates to the Rust code inside our stable branch.

The initial 4.0 code contains the following parts:

  • Re-implementation of the DNS parser, which is mostly stateless.
  • A NFS parser with logging, file extraction and basic detection integration.
  • A NTP parser done by Pierre that for a significant part is an external crate

Some initial thoughts

As predicted by many, the learning curve for Rust is indeed quite steep. It’s not just the Rust language itself, which has some novel but tricky concepts around lifetimes. It’s also the ‘nom’ framework which although generally easy to work with, can emit really cryptic compiler error messages if small mistakes (like a missing comma) are made.

Rust is really nice though. In our testing it performs well, and its really nice to have code that doesn’t segfault. In Rust, if the compiler accepts the code, it usually works. Also, conditions that may lead to undefined state in C are detected by Rust which will cause the program to to abort, instead of continuing, possibly in a condition where exploitation is possible.

Pierre’s ‘Rusticata’ work

In our initial integration we’re not using much of Pierre’s work yet. The main reasons for this are:

  • Pierre is implementing parsers as external modules (Crates in Rust speak) and we want to limit the number of external dependencies we introduce
  • learning the Rust language and ecosystem all but required that we did everything ourselves, even if it meant redoing what Pierre already did (even in less efficient ways sometimes)

However we have added another layer of ‘experimental’ for including Pierre’s work step by step.

By using the –enable-rust-experimental configure flag the parser Pierre has written are enabled.

Timeline

  • Summer 2017: Suricata 4.0 was released with experimental Rust support, implementing DNS, NFS and NTP
  • Late Fall 2017: Suricata 4.1 with still experimental Rust support, likely adding a few protocols
  • Spring 2018: Suricata 5.0 with default non-experimental (and probably mandatory) Rust support

Trying our Rust support

If you want to play with the current support, here is a page with installation instructions.

On a modern distro, it’s really as simple as installing rustc and cargo, followed by passing –enable-rust to configure. Tested on Ubuntu, Fedora and FreeBSD.

Training

In September we’re offering the third edition of our annual Suricata developer training. In this 5-day event we’re teaching how to extend Suricata. We’re planning to spend about one day on covering the Rust integration.

See: https://suricata_events.eventbrite.com/

Common questions

Q: Are you moving to Rust completely?

A: No, not anytime soon. Time will tell how this experiment evolves.

Q: Does it make Suricata harder to use?

A: No, to end-users the Rust support is transparent other than installing the build dependencies rustc and cargo.

Q: Does it make Suricata harder to compile?

A: No, not on modern distributions. All you need is the rust compiler and cargo.

Q: Where can I learn more?

A: We’re offering a developer training at https://suricata_events.eventbrite.com/

Suricata 4.0 released!

We are thrilled to announce Suricata 4.0. This is a major new release, improving detection capabilities, adding new output options and more protocols.suri-400x400

Improved Detection

Based on valuable feedback from the rule writing teams at Emerging Threats and Positive Technologies we’ve added and improved many rule keywords for inspecting HTTP, SSH and other protocols. TLS additions were contributed by Mats Klepsland at NorCERT, including decoding, logging and matching on TLS serial numbers. Additionally, Suricata now allows rule writers to specify who’s the target in a signature. This information is used in EVE JSON logging to give more context with alerts.

TLS improved, NFS added

More on the TLS side: A major new feature is support for STARTTLS in SMTP and FTP. TLS sessions will now be logged in these cases. More goodness from Mats Klepsland. Also, TLS session resumption logging is now supported thanks to the work of Ray Ruvinskiy. Additional TLS logging improvements were done by Paulo Pacheco.

NFS decoding, logging and file extraction was added as part of the experimental Rust support. Read on for more information about Rust.

More EVE JSON

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 log data extracted from traffic using a PCRE statement in rules
  • EVE can now be rotated based on time
  • EVE was extended to optionally log the HTTP request and/or response bodies
  • the (partial) flow record is added to alert records.

The ‘vars’ facility is one of the main improvements here, as it is now possible for a signature to accurately extract information for logging. For instance, a signature can extract an advertised software version or other information such as the recipient of an email. [https://blog.inliniac.net/2016/12/20/suricata-bits-ints-and-vars/]

First Step into a Safer Future

This is the first release in which we’ve implemented parts in the Rust language using the Nom parser framework. This work is inspired by Pierre Chiffliers’ (ANSSI), talk at SuriCon 2016 (pdf). By compiling with –enable-rust you’ll get a basic NFS parser and a re-implementation of the DNS parser. Feedback on this is highly appreciated.

The Rust support is still experimental, as we are continuing to explore how it functions, performs and what it will take to support it in the community. Additionally we included Pierre Chiffliers Rust parsers work. This uses external Rust parser ‘crates’ and is enabled by using –enable-rust-experimental. Initially this adds a NTP parser.

Under the Hood

A major TCP stream engine update is included. This should lead to better performance and less configuration, especially in IPS mode. First steps in TCP GAP recovery were taken, with implementations for DNS and NFS.

For developers, this release makes extending the detection engine with high performance keywords a lot easier. Adding a new high performance keyword using multi pattern matching does now requires only a few lines of code.

Documentation

David Wharton at SecureWorks 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.

Next steps

Based on the feedback we’ll get we’re expecting to do a 4.0.1 release in a month or so. Then we’ll start work on the next major release, which is 4.1. This is planned for late fall, ETA before SuriCon in Prague.

Suricata 4.0.0-beta1 ready for testing!

suri-400x400

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.
