Detect Unauthorized Assets By MAC Address
By populating the organization's assets within the assetsbystr.csv, we will be able to detect unauthorized devices that are trying to connect with the organization's network by inspecting DHCP request packets, which are issued by devices when they attempt to obtain an IP address from the DHCP server. The MAC address associated with the source of the DHCP request is checked against the list of known devices, and reports on those that are not found.
Detect Unauthorized Assets By MAC Address Help
This search uses the NetworkSessions data model shipped with Enterprise Security. It leverages the Assets and Identity framework to populate the assetsby_str.csv file located in SA-IdentityManagement, which will contain a list of known authorized organizational assets including their MAC addresses. Ensure that all inventoried systems have their MAC address populated.
