Known Issues in Splunk Enterprise Security 3.3.3

The following are issues and workarounds for this version of the Splunk App for Enterprise Security.

Highlighted issues

Publication date	Defect number	Description
3.3.1	SOLNESS-7055	When stopping or restarting the splunkd service, the service may crash in Crashing thread: IdataDO_Collector. Workaround: Disable the introspection logging on the node experiencing the crash. Validate the inputs are disabled by searching: | rest /services/configs/conf-server | eval app='eai:acl.app' | table title disabled | search title=introspection* Note: Disabling the introspection log settings will prevent the Distributed Management Console from reporting upon the status of that node.
2015-05-28	SOLNESS-6811	The threat list spyeye_ip_blocklist has been obsoleted. To disable the input, browse to Configure > Data Enrichment > Threat Intelligence Downloads, find the spyeye_ip_blocklist threat list, and select Disable.

Hardware prerequisites

Publication date	Defect number	Description
Pre-3.2	—	A dashboard view reports: Error in 'DistributedSearchResultsCollectionManager'. Operating system thread limit reached; search could not be run. This is expected behavior when the max user processes ulimit is too restrictive for the current load on the Splunk environment. See "Errors about ulimit in splunkd.log" in the Splunk Enterprise Troubleshooting Manual.

Incident Review

Publication date	Defect number	Description
3.2.1	—	Immediately after upgrading the Enterprise Security app, the Incident Review dashboard may not display notable events. The migration process from a .csv file to the KV Store feature implements a brief wait time to initialize the system. The first time ES comes up after the post-setup restart, there is a period where Incident Review will be unusable. The dashboard will become usable in a couple minutes after the migration completes.
Pre-3.2	SOLNESS-2508	The Incident Review dashboard feature does not work on the Solaris operating system.
Pre-3.2	SOLNESS-5072	The maximum number of notable events displayed for editing is 1000, regardless of the filter options or total number of notable events. This is the expected behavior set by default in the limits.conf setting max_events_per_bucket, and can be changed as required.
2014-11-19	SOLNESS-5676	The Create Notable Event workflow action may result in a truncated notable event with missing fields.
2015-01-15	SOLNESS-6054	The format of Incident Review audit data has been optimized. To review Incident Review audit events created prior to ES 3.2.1, update your audit search as needed and add the latest extractions. Example: index=_audit sourcetype=incident_review | rex field=_raw "^(?<end_time>[^,]*),(?<rule_id>[^,]*),(?<owner>[^,]*),(?<urgency>[^,]*),(?<status>[^,]*),(?<comment>[^,]*),(?<user>[^,]*),(?<rule_name>[^,]*)"

Installation and Upgrade

Publication date	Defect number	Description
Pre-3.2	CIM-169	After installing the Enterprise Security app, the splunkd.log displays a warning message: WARN LineBreakingProcessor - Truncating line because limit of 10000 bytes has been exceeded with a line length >= 13359 - data_source="/opt/splunk/var/log/splunk/remote_searches.log", data_host="nom_nom_nom", data_sourcetype="splunkd_remote_searches" Workaround: Disable truncation on the indexers using the props.conf: [splunkd_remote_searches] TRUNCATE = 0
2016-01-21	SOLNESS-8243	App import settings are not correctly replicated across search heads in a search head cluster. When this happens, the app import settings will replicate without the import information, then update to include the correct information, then replicate again without the import information. Workaround: Set up a staging server with the apps and add-ons that should be enabled and installed in your environment. Let app_imports_update.py run once on the staging server. Use the following search to determine when the script last ran. index=_internal source="*python_modular_input.log" file="app_imports_update.py*" "Meta-data updated" | stats latest(_time) by input | `uitime(latest(_time))` Disable the app_imports_update.py script. This generates a clean and correct list of apps. Copy the contents of the etc/apps directory on the staging server to the etc/shcluster/apps directory on the SHC deployer. Deploy the configurations.

Configuration

Publication date	Defect number	Description
2016-05-23	SOLNESS-9420	Extreme search causing multiple core dump files Workaround: Filter results where the size is zero. Edit the problematic context gen search in the configuration file or on the Content Management page to include |where size > 0. For example: | tstats `summariesonly` dc(All_Traffic.src) as src_count from datamodel=Network_Traffic by _time span=30m | stats count, median(src_count) as median, stdev(src_count) as size | where size>0 | xsupdateddcontext name=src_count_30m container=network_traffic terms="minimal,low,medium,high,extreme" type=median_centered width=3 app=SA-NetworkProtection scope=app | stats count
2015-04-02	SPL-99059	Modifying a data model's acceleration settings from the Settings > Data models > Edit Acceleration UI will remove any advanced configuration settings on the selected data model, such as acceleration.manual_rebuilds and acceleration.backfill_time. Workaround: Change data model acceleration settings through direct editing of the datamodels.conf files.
2015-04-15	SOLNESS-6641	A search name containing German umlaut cannot be opened in the Edit Correlation Search view. The JS console reports: Failed to load resource: the server responded with a status 500 (Internal Server Error)..

Dashboards and Reports

Publication date	Defect number	Description
Pre-3.2	—	When using a drilldown from any dashboard panel, the drilldown displays results slower than the dashboard. This is expected behavior. A drilldown runs a historical search across all indexed events mapped to the data model, where the dashboard view uses only accelerated data model objects for a faster visual response.
Pre-3.2	SOLNESS-3536	In any Individual Reports window, selecting a real-time Time Range such as: 24 hour window, 30 minute window, etc. will cause a display error: Error in 'tstats' command: This command is not supported in a real-time search. Workaround: Use a relative "Time Range" such as: Last 24 hours or Last 15 minutes.
Pre-3.2	SOLNESS-4387	When adding a report to a custom dashboard in the Enterprise Security app, the report's drilldown search may not produce the desired behavior. This includes pre-defined reports included with the Enterprise Security app. The drilldown behavior is dependent on the structure of the search, and the search commands being used. Workaround: Test all report drilldown behaviors on custom dashboards, and use Simple XML to define the drilldown search for each report as desired.
Pre-3.2	SOLNESS-4631	When using Advanced Threat dashboards, some dashboard views display a yellow warning sign triangle even if the view displays results. The warning reports: Empty csv lookup file (contains only a header) for table 'ppf_http_category': /splunk/etc/apps/DA-ESS-NetworkProtection/lookups/ppf_http_user_agent.csv Empty csv lookup file (contains only a header) for table 'ppf_url_length': /splunk/etc/apps/DA-ESS-NetworkProtection/lookups/ppf_new_domains.csv This is expected behavior and is harmless. The lookup files referenced in the warning message manages the per-panel filtering feature in Enterprise Security. Per-panel filtering is used to filter or whitelist items out of dashboard views that are deemed unimportant or non-threatening. Until the per-panel filter lookup is used, the file is empty and contains only a header. This status does not affect the functioning of the dashboard panel. For more information, see "Edit the Per-Panel Filter list" in the Enterprise Security User Manual.

Inputs

Publication date	Defect number	Description
Pre-3.2	SOLNESS-4254	While configuring or editing a modular input for a threat list, the "Interval" parameter cannot be specified through the UI. Workaround: Configure all other input parameters through the UI, and change the interval setting by editing the inputs.conf directly.
2015-12-28	SOLNESS-7659	The libtaxii library used by Enterprise Security does not support authenticated proxies. As a workaround, use an unauthenticated proxy if possible.
2016-08-04	SOLNESS-10052	lxml out-of-memory condition when parsing large TAXII feed documents Workaround: Change the earliest time for the TAXII feed to pull documents with less information, or the maxsize parameter for the threat intelligence manager to allow for a larger byte size of documents in the DA-ESS-ThreatIntelligence/local/inputs.conf file. For example: [threatlist://hailataxii_torexit] description = Hail a TAXII.com TOR LIST disabled = false interval = 86400 post_args = collection="blutmagie_de_torExits" earliest="-1y" taxii_username="guest" taxii_password="guest" earliest="-1w" type = taxii url = http://hailataxii.com/taxii-data [threat_intelligence_manager://sa_threat_local] directory = $SPLUNK_HOME/etc/apps/SA-ThreatIntelligence/local/data/threat_intel disabled = true maxsize = 52428800 sinkhole = false

Search Head Pooling

Publication date	Defect number	Description
Pre-3.2	—	Any stanza in inputs.conf that references an object in the shared pool mount must use an absolute path. In Enterprise Security, an audited lookup table requires an input. That input stanza must be updated when using search head pooling since /etc/apps/* resides on the pool, and is no longer tied to the relative path $SPLUNK_HOME. Example: In SA-ThreatIntelligence/local/inputs.conf [monitor://$SPLUNK_HOME/etc/apps/SA-ThreatIntelligence/lookups/incident_review.csv] disabled = true Lookup is on the search head pool shared storage. Changed path below: [monitor:///the/shared/storage/etc/apps/SA-ThreatIntelligence/lookups/incident_review.csv] disabled = false index = _audit sourcetype = incident_review
