Security Onion Console (SOC) gives you access to our new Alerts interface. This interface gives you an overview of the alerts that Security Onion is generating and allows you to quickly drill down into details, pivot to Hunt or the PCAP interface, and escalate alerts to TheHive.
Starting in Security Onion 2.3.60, there is a new Options drop-down menu that allows you to set options such as Acknowledged/Escalated, Automatic Refresh Interval, and Time Zone.
The first option is for
- Enabling the
Acknowledgedtoggle will only show alerts that have previously been acknowledged by an analyst.
- Enabling the
Escalatedtoggle will only show alerts that have previously been escalated by an analyst to TheHive.
Automatic Refresh Interval¶
The second option is the Automatic Refresh Interval setting:
When enabled, the Alerts page will automatically refresh at the time interval you select.
Alerts will try to detect your local time zone via your browser. Starting in Security Onion 2.3.60, you can manually specify your time zone if necessary.
The query bar defaults to
Group By Name, Module which groups the alerts by
event.module. If you want to send your current Alerts query to Hunt, you can click the crosshair icon to the right of the query bar.
Under the query bar, you’ll notice colored bubbles that represent the individual components of the query and the fields to group by. If you want to remove part of the query, you can click its corresponding bubble to remove it and run a new search.
You can click the dropdown box to select other queries which will group by other fields.
By default, Alerts searches the last 24 hours. If you want to search a different time frame, you can change it in the upper right corner of the screen.
The remainder of the page is a data table that starts in the grouped view and can be switched to the detailed view. Both views have some functionality in common:
- Clicking the table headers allows you to sort ascending or descending.
- Clicking the bell icon acknowledges an alert. That alert can then be seen by selecting the
Acknowledgedtoggle at the top of the page. In the
Acknowledgedview, clicking the bell icon removes the acknowledgement.
- Clicking the blue exclamation icon escalates the alert to TheHive and creates a case. The case can then be seen in TheHive interface. If you need to find that original escalated alert in the Alerts page, you can enable the
Escalatedtoggle (which will automatically enable the
Acknowledgedtoggle as well).
- Clicking a value in the table brings up a context menu of actions for that value. This allows you to refine your existing search, start a new search, or even pivot to external sites like Google and VirusTotal.
- You can adjust the
Rows per pagesetting in the bottom right and use the left and right arrow icons to page through the table.
By default, alerts are grouped by whatever criteria is selected in the query bar. Clicking a field value and then selecting the Drilldown option allows you to drill down into that value which switches to the detailed view.
Starting in Security Onion 2.3.60, you can also click the value in the Count column to perform a quick drilldown. Note that this quick drilldown feature is only enabled for certain queries.
If you click a value in the grouped view and then select the Drilldown option, the display will switch to the detailed view. This shows all search results and allows you to then drill into individual search results as necessary. Clicking the table headers allows you to sort ascending or descending. Starting from the left side of each row, there is an arrow which will expand the result to show all of its fields. To the right of that arrow is the
Timestamp field. Next, a few standard fields are shown:
destination.port. Depending on what kind of data you’re looking at, there may be some additional data-specific fields as well.
When you click the arrow to expand a row in the Events table, it will show all of the individual fields from that event. Field names are shown on the left and field values on the right. When looking at the field names, there is an icon to the left that will add that field to the
groupby section of your query. You can click on values on the right to bring up the context menu to refine your search or pivot to other pages.
