Call for testing: announcing Suricata 5.0.0-beta1

We’re happy to present the first beta in the upcoming Suricata 5.0 series. In 5.0 we’re making a couple of large changes.

Rust

The most visible is that our Rust support is no longer optional. We’re convinced that Rust is a perfect match for Suricata, and we plan to increase its footprint in our code base steadily. By making it mandatory we’re able to remove parallel implementations and focus fully on making the Rust code better.

Protocol Detection

The protocol detection engine has been extended to provide better accuracy as well as support for dealing with asynchronous flows. These async flows are sometimes picked up in the wrong direction and the protocol detection engine can now reverse them.

Decoder Anomaly records in EVE

A new log record type has been added: ‘anomaly’. This logs the stream and decoder events that are set by the packet decoders. This is inspired by Zeeks (Bro) ‘weird’ log.

EVE improvements

VLAN and capture interface is now part of many more EVE records, even if they are flow records or records based on flow time out.

An option to log all HTTP headers to the EVE http records has been added.

Packet Capture

Netmap support has been rewritten so the more advanced features of netmap, such as vale switches, can be used now.

Napatech usability has been improved.

Rule language: Sticky Buffers (in progress)

As discussed at the Suricon 2018 brainstorm session, a new rule keyword scheme is being introduced. It takes the existing ‘sticky buffer’ approach with new keyword names to avoid confusion. The new scheme is <proto>.<buffer>, so for example ‘http.uri’ for the URI inspection.

A number of HTTP keywords have been added.

Unified Lua inspection mixed with the sticky buffers has also been implemented.

Python 3

With Python 2’s EOL approaching, we’ve made sure that all Suricata’s python code is Python 3 compliant.

Removals

Following our deprecation policy, we have removed the following parts: the plain text dns.log, the old files-json.log and support for the Tilera architecture.

Many more things

Time line

We’re planning the first release candidate in about a month, with the final about a month later. So early July.

Get involved

If you’re interested in helping out, we’d be happy to accept patches, documentation, test reports and other kind of feedback.

Suricata 4.1.2 released

Much sooner than planned we are releasing 4.1.2. The 4.1.1 process didn’t go as planned. First the tarball was missing the vendored Rust crates. Then we found that Suricata-Update didn’t properly function on CentOS 7, Ubunut 14.04 and other slightly older distros. Then last minute we found yet another Suricata-Update bug.

So despite it being so close to the holidays for many, we decided to push 4.1.2 out already. Apologies for the inconvenience this may cause.

Other than the issues mention above, we did also fix some additional issues. SMB logging accuracy was improved, DNS detection and logging accuracy was improved and some documentation updates are included as well.

After the holidays are over we’re going to review our QA for both Suricata and Suricata-Update, so we can avoid issue like this in the future.

Changes

  • Feature #1863: smtp: improve pipelining support
  • Feature #2748: bundle libhtp 0.5.29
  • Feature #2749: bundle suricata-update 1.0.3
  • Bug #2682: python-yaml Not Listed As Ubuntu Prerequisite
  • Bug #2736: DNS Golden Transaction ID – detection bypass
  • Bug #2745: Invalid detect-engine config could lead to segfault
  • Bug #2752: smb: logs for IOCTL and DCERPC have tree_id value of 0

Announcing the Suricata Community Council

One of the most valuable moments in the Suricata development process is the annual SuriCon brainstorm. This interaction between the team and community gives the development team a lot of input for the next year.

We hope to create similar conditions more frequently. Therefore, we would like to introduce the new Suricata Community Council – an open and two-way communication channel between the Suricata community and the development team.

The council members will:

  • Provide technical advice and feedback to the development team for major releases;
  • Report on the general state of the Suricata community;
  • Participate in quarterly calls;
  • Join us at SuriCon annually.

We will have quarterly calls as well as convene in-person at SuriCon. To avoid scaling issues, we’re limiting the group’s size and have invited some contributors and other community members to join. Also, the companies at the Platinum and Gold levels of the OISF consortium will each get a representative in the council as well.

As the council comes together we will be updating the Suricata website with bios and more information. In addition, the council will post meeting minutes and updates on https://suricata-ids.org/ and the oisf mailing lists.

For questions about this exciting new community council or becoming a member of the OISF consortium, please contact us at info@oisf.net.

Suricata 4.1 beta 1 ready for testing

We are proud to announce that the first beta release for the upcoming Suricata 4.1 is ready for testing. This release is brought to you by the OISF development team with the help 25 community contributors.
