Splunk SIEM
Splunk Enterprise is a security information and event management (SIEM) platform that can be used with Bitwarden organizations. Organizations can monitor event activity with the Bitwarden app on their Splunk Enterprise dashboard.
note
The Bitwarden Splunk integration is currently supported for Splunk Enterprise on-premises.
Installing the Bitwarden app on Splunk Enterprise requires an account with Splunk Base.
Once you have a Splunk Base account, the next step is to install Splunk Enterprise. Follow the Splunk documentation to complete an install of the self-hosted Enterprise software.
note
The Bitwarden app is currently supported on Splunk Enterprise's Linux x64 architecture.
Before connecting your Bitwarden organization to Splunk Enterprise, create an index that will maintain Bitwarden data.
1. Open the Settings menu located on the top navigation bar and select Indexes.
2. Once you are on the indexes screen, select New Index.
3. A window will appear for you to create a new index for your Bitwarden app.
4. In the Index Name field, enter bitwarden_events.
note
The only required field for the index creation is Index Name. The remaining fields can be adjusted as needed.
5. When you are finished, select Save.
After your Bitwarden index has been created, navigate to the Splunk Enterprise dashboard.
1. Select the cog icon next to Apps.
2. Select Browse more apps located at the top-right on the screen.
