Alerts¶
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 PCAP, and escalate alerts to TheHive.
Toggles¶
The top of the page has toggles for Acknowledged and Escalated:
- 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¶
To the right of the toggles is the Automatic Refresh Interval setting:
When enabled, the Alerts page will automatically refresh at the time interval you select.
Query Bar¶
The query bar defaults to Group By Name, Module which groups the alerts by rule.name and 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.
Time Picker¶
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.
Data Table¶
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 theAcknowledgedview, 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 theAcknowledgedtoggle 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.
Grouped View¶
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.
Detailed View¶
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: rule.name, event.severity_label, source.ip, source.port, destination.ip, and 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.
