Notes:

DNS

Anyone sysloging to us, goes into us goes into Splunk

AWS, O365

Working on Google Apps for EDU

Getting auth logs and user lockout

Parsing alerts that come in and what severity

Separate domains for fac/staff GAE. Don’t do much alerting on content. Use Cloudlock app for Splunk

AzureAD sign-ins?

What your own app?

            Using someone from Splunkbase – Splunk add for MS cloud services. Add-on for AzureAD

With MS, can setup SIEM exporter

One app that the sec team – blue team app for O365 and Azure

https://www.ren-isac.net/public-resources/0365resources.html

Licensing levels for logs

You can buy a single elevated license to export the data. Didn’t need to have entire number of accounts to get that data.

Custom Bluecat for IPAM

Wireless logs with locations

Tracking lost/stolen devices

Some privacy implementation

Missing DNS and flow logs – concern about if affordable

Homegrown tools to do admin things – create their own logs

            Build reporting for HD

HTTP event collector – looking for cloud deployed apps – using JSON blobs

Major application stacks logging to Splunk

Dev logs into one index and servers in another

All Vuln management logs go in using Qualys – enhanced reporting

Makes the vuln mgmt. reports easier to consume. Including relative age.


Shib app going

Correlation with Radius

There’s a Shib app for Splunk?

            Yes - https://splunkbase.splunk.com/app/4389/


Yes to Banner web. For IR. Logging of host and DB.

We do PeoplesoftWeb, servers, and DB

And Workday


Peoplesoft?

            Web, server, DB audit logs

            How do you get the log? Put universal forwarder?

            Performance issue?

            App owners have expressed concerns on performance

            We haven’t seen performance issues from universal forwarder

            Config feature X to send right IP address to Splunk

            Load balancer


Issue to get Peoplesoft logs when looking at individual systems, but showing them how to look across multiple system


We’ve had a hard time in the past to universal forwarder, but haven’t really had an issue


Just looking at physical, scada, camera, door swipes, etc – response to an audit


Discussion around HR investigations

EHR investigations

Central IT disconnected to HS

Surprising that more campuses didn’t speak-up around the physical access

We have a need to collect this in Cbord and working to get into Splunk


Student health system – shouldn’t include PII


Sakai logs – for student success logs


Standards in how fac are putting data in the system – how this difficult to do without those standards in place across the fac


Has anyone dealt with the challenge around allowing people outside IT to have access to Splunk data? Fac person interested in machine learning.

            Put into roles to give them appropriate access

            Famous athletes

            Tracking from a business perspective

            Using search filters to limit access

            Governance process

            Researcher wants access to everything – how to anonymize the data

            IRB?

           

IRB education – correlated data and re-identification

What do we have to do to protect the human subject?

IRB proposal give some strength to governance


Watson chatlogs – to enhance self-service for chatbot

Lower support costs to students

Fairly small amount of json data


Hold Data sources value for next month


What do you need to do to get the logs?


Build it and they will come

Show them the value

Make getting data in easy

Don’t do a lot of control of what to log

Try to stay out of their way to get the data in

Very distributed

Have lots of docs about how to do it


How to balance with license limits?

FW change and huge growth in log size

Sec team paying for the license

Much is reporting and detection about usage of system/size of logs

Something you need to track on a day-to-day basis

Smaller campus IT that need to discuss how it’s going to be handled

Need to control the growth to meet license

Pruning turns out to take a lot of effort in this process

Hardest logs have been the business logs because of data governance

Tech and business person working together


Finish up “What do you need to do to get the logs?” on next call
