Logging DoS Protection events

Configure DoS Protection event logging on BIG-IQ

You enable DoS logging to send DoS events from your BIG-IP devices and virtual servers to your Data Collection Device (DCD).
When you provision DoS Protection on a managed BIG-IP device, you can automatically configure the necessary objects that allow BIG-IP to send DoS event messages directly to BIG-IQ. During the automated process, the following objects are created to ensure secure remote logging from the host BIG-IP device:
  • One or more Logging Profiles
  • Log Publisher
  • Log Destination
  • Pool for each device
  • Pool Members
  • Pool Monitor
To configure a log profile manually, see
Configure DoS Protection event logging.
  1. To automatically configure a logging profile to a managed BIG-IP device:
    1. Click
      Configuration
      SECURITY
      Shared Security
      DoS Protection

Configuring DoS Protection event logging over multiple DCDs

BIG-IQ receives DoS Protection events from BIG-IP via it's Data Collection Devices (DCD). To optimize the process, while ensuring high availability, it is best to load balance log events to a remote logging pool of DCDs . This will prevent data loss, in the instance that a DCD becomes unavailable, without unnecessary duplication of information.
While DoS Protection has an automated process for creating a logging profile, and its associated objects, you need manually add your DCD pool to the Log Publisher's destination list.
To complete this process for DoS Protection, you must have previously configured the following:
  • An imported and discovered BIG-IP device that hosts Dos Protection and its logging profile.
  • A remote logging pool of DCDs configured to the service port number
    8020
    .
For more information about configuring a remote pool of DCDs, see
Connect Devices to a Data Collection Device Cluster
 in the
Planning and Implementing a BIG-IQ Deployment
guide at
support.f5.com
.
If you have already created or imported your logging profile, use this process to adjust the existing settings to include the remote logging pool of DCDs.

Configure a DCD pool as a Log Destination

You must create a remote logging pool for the DCDs configured to the service port of your module. For more information see
Connect Devices to a Data Collection Device cluster
 in the
Planning and Implementing a BIG-IQ Deployment
 guide at
support.f5.com
.
Create a Remote High-Speed Log and Splunk-type Log Destination to specify that log messages are sent to your pool of DCDs.
  1. At the top of the screen, click
    Configuration
    , then, on the left, click
    LOCAL TRAFFIC
    Logs
    Log Destinations
    .
    The Log Destinations screen displays a list of the log destinations that are defined on this device.
  2. Click
    Create
    .
  3. Type a unique
    Name
    for this destination.
  4. From the
    Type
     list, select
    Remote High-Speed Log
  5. From the
    Protocol
     list, select
    TCP
    .

  7. From the
    Pool
     list, select your pool of DCDs.
  8. Click
    Save & Close
    .
    The Log Destinations screen opens.
  9. Click
    Create
    .
  10. Type a unique
    Name
     for this destination.
  11. From the
    Type
     list, select
    Splunk
    .
  12. Under the
    Forward To
     field, select
    Remote High-Speed Log
    , and select the Remote High-Speed log saved in step 8.
  13. Click
    Save & Close
    .
You have now designated your DCD pool as a remote destination for BIG-IP to send its logging data. If your system has multiple modules that require event logging, ensure that you repeat this process for the module's designated DCD pool.
Create a Log Publisher to specify that BIG-IP system sends log messages to BIG-IQ. When configuring your Log Publisher ensure you are adding the Splunk-type Log Destination.

Configure logging for DoS events

Before you configure monitoring of DoS events, you need to ensure that the DoS Protection service is enabled on the DCD.
Verify this by reviewing the services installed on the DCD on the BIG-IQ Data Collection Devices screen. Click
System
BIG-IQ DATA COLLECTION
BIG-IQ Data Collection Devices
.
If the DoS Protection service is not running, click
Activate
 to start it.
If you deactivate the DoS Protection service for a DCD, or remove a DCD with that service enabled, the associated pool member will be removed from the pool when you next deploy to the BIG-IP device (or devices). The pool
dos-remote-logging-pool_
big-ipname
contains the pool member for the specified BIG-IP device.
You configure the collection and viewing of DoS events so that you can better view and monitor information about your DoS protection. The BIG-IQ Centralized Management system provides a single-button configuration process that creates and configures the needed configuration objects. The system automatically creates the following configuration objects, if needed:
  • One or more logging profiles
  • A log publisher
  • A log destination
  • A pool for each device
  • Pool members
  • A pool monitor
  1. Click
    Configuration
