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.
- To automatically configure a logging profile to a managed BIG-IP device:
- Click.The Device DoS Configurations screen opens.
- Select one or more devices for DoS logging.
- Click more anConfigure DoS Logging.
- ClickContinue.The system will generate the listed objects to your BIG-IP device, as required for remote logging to the primary DCD in your system setup. To view these objects, select the device's row in the Device DoS Configurations screen, and the connected objects to your selection will appear in the panel at the bottom of the screen.
- To automatically configure a logging profile to a Shared Security virtual server:
- Click.
- Select one or more virtual servers for DoS logging.
- ClickMoreand selectConfigure DoS Logging.
- ClickContinue.The system will generate the listed objects to your virtual server, as required for remote logging to the primary DCD in your system setup. To view these objects, select the device's row in the Virtual Servers screen, and the connected objects to your selection will appear in the Logging Profiles area of th panel at the bottom of the screen.
- You can disable active existing logging configurations by selecting the check box next to the device or virtual server clickDisable DoS Logging(or ).
To view or manage your logging profile, go to
and select your DoS logging profile name.For managed devices running versions earlier than 13.1.0.5, you can only view events from
screens.To ensure that data is load balanced among
your DCD devices, you must change the remote log destination. For more information see
Edit log publisher destinations
. Once you have completed this process, ensure that all your changes to
your Local Traffic and Shared Security virtual servers are deployed over the host
BIG-IP device. You can deploy your changes by going to,
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 number8020.
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.
- At the top of the screen, clickConfiguration, then, on the left, click .The Log Destinations screen displays a list of the log destinations that are defined on this device.
- ClickCreate.
- Type a uniqueNamefor this destination.
- From theTypelist, selectRemote High-Speed Log
- From theProtocollist, selectTCP.
- From theDevicelist, select the BIG-IP device that hosts your service module's policy or profile.
- From thePoollist, select your pool of DCDs.
- ClickSave & Close.The Log Destinations screen opens.
- ClickCreate.
- Type a uniqueNamefor this destination.
- From theTypelist, selectSplunk.
- Under theForward Tofield, selectRemote High-Speed Log, and select the Remote High-Speed log saved in step 8.
- ClickSave & 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
.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_
contains the pool member for the specified BIG-IP
device.big-ipname
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
- Click.
- In the list, select the check box to the left of the object that will host the logging profile.
- ClickManage Loggingand selectConfigure DoS Logging.The DoS Logging Configuration dialog box opens.
- In the dialog box, clickContinue.The dialog box shows the configuration status, including which objects were created.
- ClickClose.
- Use the Deployment screens to deploy the BIG-IP device associated with the virtual server using the Local Traffic service using these steps.
- Click.
- In the Deployments area, clickCreate.
- Specify aNameandDescription, and select the appropriate deployment options.
- In the Target Device(s) area, select the device used by the application and clickCreate.
The deployment causes some of the objects created by the DoS logging configuration process to be deployed to the device. - Deploy the same BIG-IP device using either the Network Security or Web Application Security service using these steps.You can use either service since both include the Shared Security objects.
- Clickor .
- In the Deployments area, clickCreate.
- Specify aNameandDescription, and select the appropriate deployment options.
- In the Target Device(s) area, select the device used by the application and clickCreate.
The deployment causes the rest of the objects created by the DoS logging configuration process to be deployed to the device.
You have now configured your logging profile to send
DoS Protection events from the BIG-IP devices associated with the virtual servers. Once
you have deployed your changes, you can view these events on
screens. To ensure that data is load balanced among
your DCD devices, you must change the remote log destination. For more information see
Edit log publisher destinations
. Once you have completed this process, ensure that all your changes to
your Local Traffic and Shared Security virtual servers are deployed over the host
BIG-IP device. You can deploy your changes by going to,
Edit a Log Publisher Log Destination
You must have created the log destination before you
can add it to the an existing Log Publisher. For more information see
