Previously when i used the old Cisco Estreamer App to bring in Cisco firewall logs, occasionally, logs stopped coming in for whatever reason.  I would simply restart Splunk, Logs would start coming in again, and backfilling as well.  However, after migrating to the new Cisco Security Cloud app (v3.6.6), backfilling does not happen anymore.  Whenever logs stop coming in, and i restart splunk. Logs do flow in again, but it never backfills.  Does anyone know how to handle this and backfill the missing cisco logs? ... View more

Vulnerability team has flagged my Splunk instances (v9.4.9) with issues of the current version of log4j. /opt/splunk/etc/apps/splunk_archiver/java-bin/jars/thirdparty/common/log4j-core-2.17.2.jar /opt/splunk/bin/jars/thirdparty/common/log4j-core-2.17.2.jar   Installed version : 2.17.2   Fixed version     : 2.25.4  I understand you cant upgrade individual components.  But i also cant find what versions are shipped with newer versions of Splunk..  Can someone whos got the latest version, 9.4.x or 10.x.x, let me know what version of log4j is included? Thanks! ... View more

(not sure what forum location/message board to use) I currently have a non FIPS - RHEL 8 Single Site Distributed Clustered Deployment + SHC running 9.4.9.   We want to start migrating to new RHEL 9 servers but also enable FIPS.  The (wishful) plan, without going into full detail,  is to build new servers, then merge them into the existing cluster, let the SH's replicate,  decom the indexers using  offline --enforce counts,  then phase out/decom all the old RHEL 8 servers. I dont have any experience with FIPS, so my question is, can i have a mix of FIPS and non FIPS machines in a cluster?   for example, i have 3 non FIPS indexers in a cluster, can i add 3 more indexers with FIPS enabled? will they still work amongst each other? same question for SH cluster.   what about all other devices like LM, CM, SHD, DS, etc?  will a FIPS deployment server still work with devices that are NOT (yet) FIPS enabled? The end goal is to all be RHEL 9 with FIPS.. its just during the transition im not sure about, or if this is even possible. Thanks! ... View more

First time ingesting JSON logs, so need assistance on figuring out why my JSON log ingestion is not auto extracting. Environment: SHC, IDX cluster, typical management servers. I first tested a manual upload of a log sample by going to a SH then settings -> add data -> upload.   When i uploaded a log, the sourcetype _json was automatically selected. In the preview panel, everything looked good, so i saved the sourcetype as foo. i completed the upload into a index=test.  Looked at the data, everything was good, in the " interesting fields " pane on the left had the auto extractions completed. in ../apps/search/local/props.conf, an entry was created... [foo] KV_MODE = none LINE_BREAKER = ([\r\n]+) NO_BINARY_CHECK = true category = Structured description = JavaScript Object Notation format. For more information, visit http://json.org/ disabled = false pulldown_type = true BREAK_ONLY_BEFORE = INDEXED_EXTRACTIONS = json I noticed it used INDEXED_EXTRACTIONS, which is not what i wanted (have never used indexed_extractions before), but figured these are just occasional scan logs which were literally just a few kilobytes every now and then, so wasn't a big deal. I copied the above sourcetype stanza to an app in the cluster masters-manager apps folder in an app that i have a bunch of random one off props.conf sourcetype stanzas,  then pushed it out to the IDX cluster.  Then created an inputs.conf  and server class on the DS to push to the particular forwarder that monitors the folder for the appropriate JSON scan logs.   As expected, eventually the scan logs started being indexed and viewable on the Search head. Unfortunately, the auto extractions were not being parsed. The Interesting fields panel on the left only had the default fields. on the Right panel where the logs are the Fields names were highlighted in Red, which i guess means splunk recognizes the field names??  But either way the issue is i had no interesting fields. I figured maybe the issue was on the Search heads i had the " indexed extractions"  set and figure thats probably an indexer setting,    so i commented that out and tried using KV_MODE=json in its place. saved the .conf file and restarted the SH.  But the issue remains.. no interesting fields. The test upload worked just fine and i had interesting fields in the test index,  however when the logs started coming through from the UF,  I no longer had interesting fields despite using the same sourcetype. What am i missing? is there more to ingesting a JSON file then simply just using  kv_mode  or indexed_extractions?  but then why does my test upload work ? here is a sample log:   {"createdAt": "2024-09-04T15:23:12-04:00", "description": "bunch of words.", "detectorId": "text/[email protected]", "detectorName": "Hardcoded credentials", "detectorTags": ["secrets", "security", "owasp-top10", "top25-cwes", "cwe-798", "Text"], "generatorId": "something", "id": "LongIDstring", "remediation": {"recommendation": {"text": "a bunch of text.", "url": "a url"}}, "resource": {"id": "oit-aws-codescan"}, "ruleId": "multilanguage-password", "severity": "Critical", "status": "Open", "title": "CWE-xxx - Hardcoded credentials", "type": "Software and Configuration Checks", "updatedAt": "2024-09-18T10:54:02.916000-04:00", "vulnerability": {"filePath": {"codeSnippet": [{"content": " ftp_site = 'something.com'", "number": 139}, {"content": " ftp_base = '/somesite/'", "number": 140}, {"content": " ftp_filename_ext = '.csv'", "number": 111}, {"content": " ", "number": 111}, {"content": " ftp_username = 'anonymous'", "number": 111}, {"content": " ftp_password = 'a****'", "number": 111}, {"content": "", "number": 111}, {"content": " # -- DOWNLOAD DATA -----", "number": 111}, {"content": " # Put all of the data pulls within a try-except case to protect against crashing", "number": 111}, {"content": "", "number": 148}, {"content": " email_alert_sent = False", "number": 111}], "endLine": 111, "name": "somethingsomething.py", "path": "something.py", "startLine": 111}, "id": "LongIDstring", "referenceUrls": [], "relatedVulnerabilities": ["CWE-xxx"]}}   I appreciate any guidance.. ...

I have 3 standalone indexers, and another 3 indexers in a cluster.  We want to decommission the 3 standalones but first, have to move the data off the 3  onto the cluster.   I imagine the process would be something like to roll all hot buckets to warm.. then rsync the warm and cold mounts/directory to a temp directory on one of the idx cluster members? standalone 1 to idxcluster 1,, 2 to 2, then 3 to 3.. But when we do rsync the data over.. How do i get the new indexer to recognize the old imported data?  is it as simple as merging the old imported data into the appropriate index directory on the new indexer?  for example.. copy the old wineventlog index, into the same named directory on the  new indexer? would that work or is there  more to it?  Is there some kind of splunk native command to move all data from idx A to idx B? Is there a better (or correct) way to make the new idx recognize the imported data? I appreciate any help!  Thanks. ... View more

Hello, all! Im hopefully looking for an ELI5 (explain like im 5) on the best way to migrate indexer cluster database to an entirely new cluster environment. The end goal is to decommission the current setup. My current setup.  RHEL 7, physical,  splunk 8.2.4. All log sources are still flowing to this setup. 3sh cluster, 3 idx cluster, 1cm, etc. New: RHEL 8,  AWS/VM's, splunk 9.1.1. This setup is still empty with no logs/sources flowing here yet. 3sh cluster, 3 idx cluster, 1cm, etc. From what i found online.. merging the 3 new indexers into the old cluster seems to be the preferred method.  Does anyone have a link to a detailed writeup on how to do so with all the little nuances comes with it?  are differing splunk versions okay?  do i change rep factor? im sure there are a bunch of steps to this method. I appreciate any help! ... View more
