Rule Sets

One of the most important components of the Sycope system is alerting functionality. This functionality allows the user to flexibly build Alerts based on a number of conditions and rules that operate on the data streams collected by the system.

Sycope includes many predefined Alerts created by a team of cybersecurity experts. These rules can be used as a template from which you can create your own rules. You can also create rules on your own using the wizard.

This menu [Alerts>Rules Set] can be used to create a custom rule based on the selected Streams and (optional) your own mathematical function. The system includes many of the most useful predefined rules that you can use right after installing the system.

The list of Rules is in the table with the following columns:

  • Rule name - unique Rule name
  • Rule type
  • Tactic
  • Technique
  • Score
  • Created by
  • Creation Time
  • Modified By
  • Modification Time
  • Tags
  • Active
  • Action
    • Edit - edit an existing Rule
    • Duplicate - create an editable copy of the selected Rule
    • Export - export Rule to json format
    • Delete - delete

Adding custom rule

Alarm rules are created and edited in this menu [Alerts>Rule Set].

To add a new Alert rule, click on the New rule button, then the wizard will appear.

The rule configuration wizard consists of the following sections:

  • General

    • Join - returns concatenated value of fields values.

    • Last - returns value of last field returned.

    • Max - returns maximal value.

    • Min - returns minimal value.

    • Sum - returns sum of values.

Categories​

  • Agreggation - list of operations to choose

Sorting​

Here you can define how to sort the data displayed on the graph.

    • Head
    • Tail

  • Show others switch

    • Others label

      Schedule

In this step you can specify how often the rule will be executed.

  • Interval - Set number in units Min/Hours/Days/Weeks/Months/Years defining the time interval.
  • Throttling in minutes
  • Indexed fields

Thresholds​

  • Value

    • Minor - select an operator and a value
    • Major - select an operator and a value
    • Critical - select an operator and a value

    First the Critical conditions are checked, if these conditions are not met then the Major conditions are checked, and if these conditions are not met then the Minor conditions are checked.
