Merge pull request #308 from cisagov/v24.04.0_merge_cisagov Malcolm v24.04.0 * Features and enhancements - Zeek-extracted files scanned and preserved on a [Hedgehog Linux](https://cisagov.github.io/Malcolm/docs/malcolm-hedgehog-e2e-iso-install.html#HedgehogZeekFileExtraction) sensor can now be accessed via [the extracted files download user interface](https://cisagov.github.io/Malcolm/docs/file-scanning.html#ZeekFileExtractionUI) (idaholab#331). - Improvements to creation of index templates, dashboards, and other saved objects on startup (idaholab#208) to ensure that saved objects get created correctly upon upgrade (see [this comment](idaholab#208 (comment)) for more details on this feature). - [Populating the NetBox inventory via passively-gathered network traffic metadata](https://cisagov.github.io/Malcolm/docs/asset-interaction-analysis.html#NetBoxPopPassive) now uses network traffic logs for DNS, NTLM, and DHCP to identify assets' host names when possible for use when populating device and VM names (idaholab#415). Autopopulated devices now have their *status* field set to `Active` rather than `Stage`, and uses *tags* instead to indicated that they were created through autopopulation. - Users can now specify pruning thresholds for [carved files](https://cisagov.github.io/Malcolm/docs/file-scanning.html#ZeekFileExtraction) so that old files are deleted in order to avoid filling available storage (idaholab#453). See a new section of documentation on [Managing disk usage](https://cisagov.github.io/Malcolm/docs/malcolm-config.html#DiskUsage) for more information about this and similar settings. - Users can now specify a prefix that will be prepended to dashboards as they are imported into OpenSearch Dashboards or Kibana, allowing users who have dashboards from other sources to differentiate between those and Malcolm's (idaholab#455). - The default anomaly detectors created for the OpenSearch Anomaly Detection plugin are now created with [category fields for high cardinality](https://opensearch.org/docs/latest/observing-your-data/ad/index/#optional-set-category-fields-for-high-cardinality) to allow for better breakdown of contributing values to anomalies discovered (idaholab#464). - Include [JA4+ plugin in Arkime](https://arkime.com/settings#ja4plus). See idaholab#419 for status on upcoming full JA4+ support in Malcolm. - Hedgehog Linux sensors can now [periodically refresh](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/hedgehog-iso/interface/sensor_ctl/control_vars.conf#L75) their [Zeek inteligence files](https://idaholab.github.io/Malcolm/docs/hedgehog-config-zeek-intel.html#HedgehogZeekIntel). **NOTE**: due to an oversight, a necessary variable is missing in this release that is required for this to work. Appending the line `export INTEL_DIR=/opt/sensor/sensor_ctl/zeek/intel` to `/opt/sensor/sensor_ctl/control_vars.conf` will correct this. This will be corrected in the next Malcolm release. - Assorted documentation improvements. * Component version updates - Arkime to [v5.1.2](https://github.com/arkime/arkime/blob/bcd9d7e68be8e4a52a17c35211c5d5a7fdcc1a1c/CHANGELOG#L36-L41) - OpenSearch and OpenSearch Dashboards to [v2.13.0](https://github.com/opensearch-project/opensearch-build/blob/main/release-notes/opensearch-release-notes-2.13.0.md) - Beats to [v8.13.2](https://www.elastic.co/guide/en/beats/libbeat/current/release-notes-8.13.2.html) - Logstash to [v8.13.2](https://www.elastic.co/guide/en/logstash/current/logstash-8-13-2.html) - gunicorn to v22.0.0 to address [CVE-2024-1135](GHSA-w3h3-4rj7-4ph4). - elasticsearch-dsl to [v8.13.0](https://github.com/elastic/elasticsearch-dsl-py/releases/tag/v8.13.0) - elasticsearch-py to [v8.13.0](https://github.com/elastic/elasticsearch-py/releases/tag/v8.13.0) - idna to v3.7 to address [CVE-2024-3651](GHSA-jjg7-2v4v-x38h) - Fluent Bit to [v3.0.3](https://fluentbit.io/announcements/v3.0.3/) * Bug fixes - The documentation for [Windows host system configuration](https://cisagov.github.io/Malcolm/docs/host-config-windows.html#HostSystemConfigWindows) was out of date and has been updated for the latest version of Microsoft Windows Subsystem for Linux (idaholab#421). - An issue was fixed in which Malcolm's list of users and their password hashes could become corrupted if the file did not initially end with a newline character (idaholab#426). - The manner in which Zeek intel files are generated has been changed to avoid problems found in Kubernetes deployments when scaling out the number of `zeek-live` containers (idaholab#456). See [this comment](idaholab#456 (comment)) for more details. - Removed the version top-level element from `docker-compose.yml` files as it is [now obsolete](https://docs.docker.com/compose/compose-file/04-version-and-name/) and caused a warning message that sometimes was not handled correctly. - Fix Malcolm ISO not correctly detecting if it's in a live boot ISO environment or installed mode. - Restart live Zeek instances with `zeekctl deploy` instead of `zeekctl restart`. * Configuration changes (in [environment variables](https://cisagov.github.io/Malcolm/docs/malcolm-config.html#MalcolmConfigEnvVars) in [`./config/`](https://github.com/idaholab/Malcolm/blob/v24.04.0/config)) - `ARKIME_QUERY_ALL_INDICES` in [`arkime.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/arkime.env.example#L9-L11) can be set to control the [`queryAllIndices` setting](https://arkime.com/settings#queryAllIndices) in Arkime's `config.ini`. - `DASHBOARDS_PREFIX` in [`dashboards-helper.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/dashboards-helper.env.example#L3C1-L4C19) has been added for idaholab#455 (see above in **Features and Enhancements**). - `LOGSTASH_NETBOX_ENRICHMENT_DATASETS` in [`logstash.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/logstash.env.example#L13) has been changed to include `zeek.dhcp`, `zeek.dns`, and `zeek.ntlm` to support idaholab#415 (see above in **Features and Enhancements**). - `LOGSTASH_ZEEK_IGNORED_LOGS` in [`logstash.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/logstash.env.example#L15) has been changed to remove `capture_loss` and `stats` so that those diagnostic Zeek logs can be parsed without the user having to manually change this variable. - `ZEEK_CRON` has been removed from [`zeek-live.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/zeek-live.env.example) and `ZEEK_INTEL_REFRESH_CRON_EXPRESSION` was removed from [`zeek.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/zeek.env.example) and moved to the "offline" version of the container in [`zeek-offline.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/zeek-offline.env.example#L17-L19) for idaholab#456. - `EXTRACTED_FILE_PRUNE_THRESHOLD_MAX_SIZE`, `EXTRACTED_FILE_PRUNE_THRESHOLD_TOTAL_DISK_USAGE_PERCENT`, and `EXTRACTED_FILE_PRUNE_INTERVAL_SECONDS` were added to [`zeek.env`](https://github.com/idaholab/Malcolm/blob/bceee4616dd5676a010a3dd7b0410856257948e8/config/zeek.env.example#L32-L37) for idaholab#453.
