Chronicle enables you to investigate specific domains to determine if any are present within your enterprise, and what impact these outside systems might have had on your assets. Domain view is derived from the security information and data that you have forwarded to Chronicle. Make sure you are ingesting and normalizing data from devices on your network, such as EDR, firewall, web proxy, etc.
To access Domain view in Chronicle, complete the following steps:
- Enter the domain (ending with a known public suffix) or URL you need to investigate in the search bar at the top of the user interface.
- Click SEARCH. If the domain is present within your enterprise, you are taken to Domain view.
Displays the unique assets within your enterprise that have connected to a particular domain, including a summary of the first time the asset accessed the domain and the most recent time.
Chronicle displays the WHOIS information associated with the registered domain. This information can be useful when assessing a domain's reputation.
Chronicle provides a graphical representation of the historical prevalence of a given FQDN and its TLD. This graph can be used to determine whether the domain has been accessed from within the enterprise before, and can provide an indication of whether the domain is associated with a particular campaign targeting the enterprise. Typically, less prevalent domains, ones that fewer assets have connected to, might represent a greater threat to your enterprise.
4 Domain insights
Domain insights provide you with more context about domains under investigation. You can use them to determine whether a domain is benign or malicious. They also let you further investigate an indicator to determine if there is a broader compromise.
