# Asset Merge | ||
|
||
It may be possible that your devices share a common mac address or another key field that is causing an erroneous merge of your assets. If Crowdstrike is your only data source for assets, you can disable asset merge in the global settings. | ||
It is possible that some of your devices share a common key field (`dns`, `ip`, `mac`, `nt_host`) that is causing an erroneous merge of your assets. There are a few ways to overcome this: | ||
|
||
- [Disable Asset merging](#disable-asset-merging) | ||
- [Update Asset key fields](#update-asset-key-fields) | ||
|
||
## Problem Scenario | ||
|
||
Consider you have the following assets: | ||
|
||
Host | dns | ip | mac | nt_host | ||
---- | --- | -- | --- | ------- | ||
host1 | host1.local | ==10.0.34.9== | 77:61:f5:cb:33:a7 | host1 | ||
host2 | host2.local | ==10.0.34.9== | a5:e7:5c:39:77:d1 | host2 | ||
|
||
Since these two systems share the same IP they will be merged into a single asset by default. | ||
|
||
### Default merge | ||
|
||
Asset | dns | ip | mac | nt_host | ||
----- | --- | -- | --- | ------- | ||
host1<br>host2<br>host1.local<br>10.0.34.9<br>77:61:f5:cb:33:a7<br>a5:e7:5c:39:77:d1 | host1.local<br>host2.local | 10.0.34.9 | 77:61:f5:cb:33:a7<br>a5:e7:5c:39:77:d1 | host1<br>host2 | ||
|
||
### Expected behavior | ||
|
||
<small>_see next section to accomplish this expected behavior_<small> | ||
|
||
Asset | dns | ip | mac | nt_host | ||
----- | --- | -- | --- | ------- | ||
host1<br>host1.local<br>10.0.34.9<br>77:61:f5:cb:33:a7 | host1.local | 10.0.34.9 | 77:61:f5:cb:33:a7 | host1 | ||
host2<br>host2.local<br>10.0.34.9<br>a5:e7:5c:39:77:d1 | host2.local | 10.0.34.9 | a5:e7:5c:39:77:d1 | host2 | ||
|
||
## Solutions | ||
|
||
### Disable Asset Merging | ||
|
||
If Crowdstrike is your **_only_** data source for assets, you can disable asset merge in the global settings. | ||
|
||
!!! warn "This is not recommended if you have more than one asset list configured (see next section)" | ||
|
||
1. In Enterprise Security navigate to Configure > Data Enrichment > Asset and Identity Management > Global Settings. | ||
1. Toggle off "Assets" under `Enable Merge for Assets or Identities`. | ||
|
||
Changes should reflect the next time the Asset database builds (usually 5-10 minutes). | ||
|
||
<small>\*_For more information, see [Splunk Docs](https://docs.splunk.com/Documentation/ES/latest/Admin/Merge){ target="blank" }._</small> | ||
|
||
### Update Asset Key Fields | ||
|
||
If you have more than one asset list configured you can look at disabling the common key field to prevent the default merging behavior. | ||
|
||
!!! tip "In most cases, the IP field will be field that needs to disabled as the key field." | ||
|
||
1. (In Enterprise Security) Navigate to Configure > Data Enrichment > Asset and Identity Management. | ||
1. Select the "Asset Fields" Tab. | ||
1. Select the `ip` field (or the field you want to disable) and "uncheck" it from being a Key. | ||
