Creating Security Alert Definitions

You can create an alert definition to monitor your data in real time. You can identify issues and attacks before they impact your network.

For example, if you are an administrator, you can define a condition such that if the number of firewall deny events crosses a predefined threshold in a given time frame for a specific device, you receive an e-mail alert.

Procedure

To create a security alert definition:

  1. Select Monitor > Alerts & Alarms > Definitions/Notifications > Security Alerts Definitions.

    The Security alert definitions page appears.

  2. Click the create icon (+) or add icon (+).

    The Create an Alert Definition page appears.

  3. Complete the configuration according to the guidelines provided in Table 297.
  4. Click OK. If you want to discard the changes, click Cancel instead.

A new alert definition with the configured alert triggering condition is created. You can view the generated alerts from the alert definition to troubleshoot the issues with your system.
