Doesn't seem to work anymore. might need a flag option for ssl_verify=false (or something more secure 🙂 ) AttributeError at "/opt/splunk/etc/apps/TA-VirusTotal/bin/virustotal.py", line 508 : 'SSLError' object has no attribute 'message'

Hi there, Is it possible to search for windows interactive logons from the Authentication data model? eg. I can do it this way: index=* source="*WinEventLog:Security" LogonType=2 OR LogonType=10 OR LogonType=11 And I'm looking for an equivalent way using a data model eg: | tstats summariesonly=true count from datamodel=Authentication by Authentication.action Authentication.app Authentication.dest Authentication.signature Authentication.src Authentication.src_user Authentication.user |search <SOME LOGIC> Thank you!

dbroggy · ‎04-22-2022

I'm not seeing this Security_ID field for the transaction in my windows logs, I understand the rest of your logic perfectly.

old topic, but SSE has changed a lot since 2020. Simple answer: SSE: Setup > Content Introspection - will auto scan your existing log sources and then provide recommendations for your security use cases. BE PATIENT! Introspection queries ALL of your data so best to use this button on a new system vs one with tons of data. I don't know a way to limit the scanning range. Plan B: Setup > Data Inventory - manually map your log sources to the long list of data source types.

I would really love to use Campus Compliance Toolkit for NIST 800-171 But I have Splunk Cloud Enterprise. Splunkbase says version 1.0.2 works, but sadly Splunk support says it doesn't. Is there any chance others like this tool and have made it work? Or is there an alternative NIST reporting app out there (that doesn't require an annual license fee)? Thank you for your feedback.

that presentation seems to just say 'get enterprise security'.

I love the simplicity of SMFS Why was it discontinued? Security Essentials isn't really suited for the same purpose.

Hi Everyone, I'm looking for some Splunk Enterprise Security tips, maybe in the form of a cheatsheeet. Specific topics of interest: 1. Recommended 'base apps' for ES, eg: CIM ESCU CIM-Validator lookup file editor knowledge object explorer more?? 2. Some sort of validator for apps/addons for all required sourcetypes, and info on which peer to install them on. eg. For Azure: SH - App and addon, HF - App and addon 3. And finally ways to quickly validate logs eg: use CIM Validator, pick a log source and match it to a datamodel - verify the required fields exist. if it fails, and the sourcetype is supposed to be CIM compliant, verify you've installed the appropriate app/addon on the SH and/or HF. or use queries like this to validate your logs, based on a table that matches the required fields: |datamodel Intrusion_Detection IDS_Attacks search|dedup sourcetype|rename IDS_Attacks.* as *|table sourcetype action category dest signature src user vendor_product I would greatly appreciate your feedback and better ways to validate your ES installation. Thanks.

none of the above queries seem to work.

dbroggy · ‎01-23-2021

Not close to a perfect solution but it works for me: Run this query to get the rules and SPL: | rest splunk_server=local count=0 /services/saved/searches |table title, search Filter down just the titles with the word 'Rule' at the end of the title. Ok so now you have the rule names and the spl for each. Then I do some messy sed/awk/grep to extract the data models associated with each - this is optional. Then I read each rule and it's usually not difficult to guess which logs sources would probably work with those rules - eg: if the rules starts with 'Access', I put os/auth/AD Endpoint - endpoint (easy) etc. etc. There's ONLY about 350 rules so take some time and you'll at least have a decent short list to focus on.

dbroggy · ‎02-13-2020

Or if you don't care to see all of those fields: | rest splunk_server=local /services/search/distributed/peers/ |table splunk_server server_roles version However this query may not list roles for any of: cluster master license server deployment server monitoring console

try saving as a report, enabling report acceleration, and then apply the report to your dashboard.

you mean this? https://splunkbase.splunk.com/app/4336/#/details

dbroggy · ‎09-10-2019

Thanks for trying, but it's not that cut and dry. There are several links leading off of the link you mentioned which point to both github and splunkbase, and some refer to BOTS 1.0 and some refer to 2.0.

dbroggy · ‎09-10-2019

Right, but on that link you mentioned it says this: BOTS 2.0 Questions and Answers We're happy to send you a copy of the BOTS 2.0 questions and answers upon request! All you have to do is register here. That link in 'here' uses this link: https://events.splunk.com/BOTS_2_0_datasets And once you fill out that form you're supposed to get access to the questions like these:

dbroggy · ‎09-10-2019

There seem to be 3 apps for the scorecard: SA-ctf_scoreboard SA-ctf_scoreboard-master SA-ctf_scoreboard_admin But scoreboard and scoreboard-master have the same app title, so if you install both of them you end up with 2 'Capture the Flag' apps listed in Splunk. is SA-ctf_scoreboard obsolete?

dbroggy · ‎09-10-2019

There's supposed to be a list of questions that can be used with the BOTS data set. From what I've read you have to fill out the form in a link. I filled out the link form, but there's no clarity on how I get the questions after that's done.

dbroggy · ‎07-02-2019

here's the command line way: splunk enable web-ssl splunk set web-port 443 splunk restart (assuming you're using the built in ssl keys)

I'm not sure what your alert is looking at but normally the trigger time would be the same time as the last event associated with your alert. I appreciate whatever is actually set as the trigger time information might not be stored in your event but generated via backend python. eg. https://answers.splunk.com/answers/293978/how-to-change-the-alert-email-trigger-time-format.html

dbroggy · ‎07-01-2019

Why don't you just add an eval function to your alert query and calculate the time difference into a new key or overwrite the trigger time key?

dbroggy · ‎07-01-2019

Unless you're using a sniffer to collect your logs (most people aren't) the logs won't be encrypted between your dns server and splunk. If they are, there should be a supported mechanism like HEC or secure syslog.

dbroggy · ‎07-01-2019

more current answer is here: https://answers.splunk.com/answers/607068/the-maximum-number-of-concurrent-historical-search.html I beleive it simply comes down to how many searches you're running vs how many cpu's you have. If you bother to change limits.conf just to remove the message it won't change the fact that you're limited by the number of cpus.

dbroggy · ‎06-23-2019

But I'm pretty sure that's the wrong syntax. "-mode slave" assigns an indexer to the indexer cluster. And search heads don't do replication to an index cluster so replication_port makes no sense. The command should be: ./splunk edit cluster-config -mode searchhead -site site0 -master_uri https://:8089 -secret pass123 Ref: https://docs.splunk.com/Documentation/Splunk/6.4.1/DistSearch/SHCandindexercluster

dbroggy · ‎06-23-2019

I don't understand why Thomas is using the cluster-config command to add a search head. should be the shcluster-config command.

dbroggy · ‎05-28-2019

those onboarding guides are terrific. is there any way to export them all or will Splunk be providing a web resource for that outside of the app? thanks.
