You can create orchestration rules in USM Anywhere that automatically trigger a Box response action when alarmsAlarms provide notification of an event or sequence of events that require attention or investigation. match the criteria that you specify. For example, you can create a rule where USM Anywhere automatically disables the user when authentication to Box from a known malicious host occurs.
Warning: Be careful when automating the disabling of users because an error in the logic could result in all of your users, including administrators, being locked out. The only way to recover would be to contact Box support.
After you create a rule, new alarms that match the rule conditions will trigger the Box response action. The rule does not trigger for existing alarms.
You can create a new rule in one of two ways:
From an Applied Response Action: You can create a rule using the response action that you apply to an existing alarm. This makes it easy to set the matching conditions for the rule based on the existing item and use the same settings that you applied to that item.
In the confirmation dialog box, click Create rule for similar alarms.
From the Rules page: The Rules page provides access to all of your orchestration rules. The Orchestration Rules list includes suppression rules, alarm rules,
event rules,filtering rules, notification rules, and response action rules. You can create new rules using the specific matching conditions that you define, as well as edit, delete, and enable or disable rules. See Orchestration Rules for more information about managing orchestration rules.
In the left navigation menu, go to Settings > Rules and select Response Action Rules. Then click Create Response Action Rule to define the new rule.
To define a new Box response action rule
- Enter a name for the rule.
- In the Action Type list, select Box.
- In the App Action list, select the action you want to use.
Fill out the required fields.
At the bottom of the dialog box, set the rule condition parameters to specify the criteria for a matching alarm or event to trigger the rule.
- This section provides suggested property/value pairs from the selected alarm or event that you can use as conditions for the rule. Click the icon to delete the items that you do not want to include in the matching conditions. You can also add other conditions that are not suggested.
- If you create the rule from the Rules page, you must use the Add Condition and Add Group functions to define the property/value pairs that you want to use as conditions for the rule.
- At the bottom of the dialog box, click More to display the optional multiple occurrence and window-length parameters.
Select an operator and add one or more conditions to form the conditional expression. You can include a condition group to evaluate a subset of conditions. The Current Rule pane displays the constructed expression in standard syntax. The box displays a red border if the expression is syntactically invalid as currently specified. A valid expression is required to save the rule definition.
Select the operator used to determine the match for multiple conditions:
- AND: Match all conditions
- OR: Match any one condition
- AND NOT: Exclude items matching all conditions after the first
- OR NOT: Include all items that do not match any conditions after the first
Click Add Condition to add a condition. For each condition, specify the field name, evaluator, and value. If the evaluation returns true for the condition, it is a match.
Click Add Group to add a condition group. A new group includes a condition and its own operator used to match the conditions within the group. You can nest condition groups.Occurrences
Specify the number of event or alarm occurrences that produce a match on the conditional expression to trigger the rule. The default value is 1. You can enter the number of occurrences or use the arrow to scroll the value up or down.
USM Anywhere uses this in conjunction with the Length option to specify the number of occurrences within a time period that will trigger the rule. For example, you can define a rule to trigger for an unauthorized access attempt when a failed SSHProgram to securely log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another through Secure Copy (SCP). login occurs three times within a five-minute window.Length
Specify the length of the window to identify a match for multiple occurrences. Enter the number and choose a time unit value of seconds, minutes, or hours. This time period identifies the amount of time that transpires from the first occurrence to the last occurrence. If the number of occurrences is not met within this period, the rule does not trigger.
- Click Save Rule.
- In the confirmation dialog box, click OK.
