Managing Logging Profiles in Shared Security
About logging profiles
A
logging profile
records requests to a virtual server hosted on a BIG-IP device. A
logging profile determines whether and where events are logged, and which items (such as which parts of
requests, or which type of errors) are logged. Events can be logged either locally by is configured to record the
system and viewed in the Event Logs screens, or remotely by an external logging system. The system
forwards the log messages to an external logging server using the Syslog service.The following default logging profiles are imported from the BIG-IP device:
- Log all requests
- Log illegal requests
- global-network
- local-dos
The BIG-IQ Centralized
Management system creates the following logging profiles:
- Thetemplates-defaultlogging profile is the default logging profile for application templates.
- Theafm-remote-logging-profilelogging profile can be created automatically when configuring Network Security event monitoring. For information on the configuration process, refer to theMonitoring Network Security eventstopics inF5 BIG-IQ Centralized Management: Monitoring and Reportingonsupport.f5.com.
- Thedos-remote-logging-profile-afmordos-remote-logging-profile-asm-logging profile can be created automatically when configuring DoS event monitoring. For information on the configuration process, refer to theMonitoring DoS eventstopics inF5 BIG-IQ Centralized Management: Monitoring and Reportingonsupport.f5.com.
The logging profile can be associated with multiple virtual servers from
multiple devices. Multiple logging profiles can be associated with a virtual server, but the
multiple logging profiles cannot have an overlap subset configured. For example, two logging
profiles with application security configured and enabled cannot be associated with the same
virtual server. Application security and protocol security cannot be configured on the same
logging profile or associated with the same virtual
server.
BIG-IQ Centralized Management supports importing
logging profiles with spaces in the name. An imported logging profile with spaces in the name
can be modified on the BIG-IQ system and deployed back to a BIG-IP device. However, BIG-IQ
does not support creating logging profiles with spaces in the name.
The logging publisher specified by the BIG-IQ system logging
profile should be the same as that configured on the BIG-IP device.
If a BIG-IQ system adds or removes data collection devices (DCDs), that causes a change to
be made to the remote logging event settings in the
templates-default
logging
profile on the BIG-IQ system. A subsequent deployment of that BIG-IQ configuration to a
managed BIG-IP device or a rediscovery or reimport of that BIG-IP device will show differences
for the templates-default
logging profile, since the BIG-IQ version of that
profile has changed.Create a new logging profile
You create logging profiles to
configure the kind of information to log for objects that support logging.
- Click.
- On the Logging Profiles screen, clickCreate.The New Logging Profile screen opens with the Properties displayed.
- In theNamefield, type a name for the logging profile.
- In theDescriptionfield, type an optional description for the logging profile.
- If needed, change the defaultCommonpartition in thePartitionfield.The partition with that name must already exist on the BIG-IP device. No whitespace is allowed in the partition name. Only users with access to a partition can view the objects (such as the logging profile) that it contains. If the logging profile resides in theCommonpartition, all users can access it.
- In theAvailable in Application Templatessetting, select whether the profile is available to application templates.
- To make the profile available to application templates, selectYes.
- To remove the profile from being available to application templates, selectNo.
- On the left, click the logging type that you want to use, and then select theEnabledcheck box to display the related settings.
- EnableApplication Securityto specify that the system logs traffic to the web application. You cannot enable bothApplication SecurityandProtocol Security. Refer to theConfigure for Application Security loggingsection ofBIG-IQ Centralized Management: Securityonsupport.f5.comfor configuration information.
- EnableProtocol Securityto specify that the system logs any dropped, malformed, and/or rejected requests sent through the given protocol. Refer to theConfigure for Protocol Security loggingsection ofBIG-IQ Centralized Management: Securityonsupport.f5.comfor configuration information.
- EnableNetwork Firewallto specify that the system logs ACL rule matches, TCP events, and/or TCP/IP errors sent to the network firewall. Refer to theConfigure for Network Firewall loggingsection ofBIG-IQ Centralized Management: Securityonsupport.f5.comfor configuration information.
- EnableNetwork Address Translationto specify which Network Address Translation (NAT) events the system logs, and where those events are logged. Refer to theConfigure for Network Address Translation loggingsection ofBIG-IQ Centralized Management: Securityonsupport.f5.comfor configuration information.
- EnableDoS Protectionto specify that the system logs detected DoS attacks, and where DoS events are logged.
- EnableBot Defenseto specify that the system logs bot defense events. Refer to theConfigure for Bot Defense loggingsection ofBIG-IQ Centralized Management: Securityonsupport.f5.comfor configuration information.
You must configure each enabled logging type before you can use it. You can do that now, or save the profile and configure the logging types later. See the configuration procedures for each type of logging profile below. - Specify the settings needed for each logging type you use.You can configure multiple logging types while editing the logging profile.
- When finished, save your changes.

Configure DoS Protection logging per protocol
Before you can log DoS protection events, you must first have configured DoS protection to one of more of your managed BIG-IP devices. In addition, you must have data collection devices (DCD) within your BIG-IQ
configuration. You must also activate Web Application Security for your DCD services
(
).If you are configuring a logging profile for remote logging (including sending log data to BIG-IQ), you will need to configure remote publishing objects, including a pool and pool monitor that can securely send data from the host device to your DCDs. F5 recommends you use automatic DoS Protection event logging (see
Configure DoS Protection event logging on BIG-IQ).
For logging bot requests from BIG-IP devices version 14.1 or later, see
Configure Bot Defense logging.
You need to configure DoS protection
logging profiles to determine the kind of
information that is logged.
You can
do this configuration when initially creating a logging profile (in which case go
directly to step 5), or perform the configuration later in a logging profile that
already exists.
- Click.
- On the Logging Profiles screen, click the name of the logging profile to configure.The logging profile properties are displayed.
- On the left, clickDoS Protection.The DoS Protection configuration screen opens.
- ForStatus, select theEnabledcheck box.The screen displays the DoS Protection properties.
- Supply the DoS Application Protection settings to configure where DoS application protection events are logged.
- EnableLocal Publisherto specify that the system logs DoS events to the local database (on the host BIG-IP device).
- Select aRemote Publisherto specify the name of the log publisher used for logging events. Select a log publisher configured in your system. This option includes publishing to BIG-IQ. Ensure you select this option to view data in central management.If your system contains multiple Data Collection Devices (DCDs), F5 recommends to load balance events, which provides high availability. For configuring high availability seeDoS Protection event logging over multiple DCDs.
- In the DNS DoS Protection area, configure where DNS DoS protection events are logged: Select aPublisherto specify the name of the log publisher used for logging events. Select a log publisher configured in your system.
- For the SIP DoS Protection area, configure where SIP DoS protection events are logged: Select aPublisherto specify the name of the log publisher used for logging events. Select a log publisher configured in your system.
- For the Network DoS Protection area, configure where Network DoS protection events are logged: Select aPublisherto specify the name of the log publisher used for logging events. Select a log publisher configured in your system.
- When you are finished, save your changes.

Manually configure logging for Bot Defense requests
Before you can log bot
requests, you must first have the following:
- One or more BIG-IP devices that are provisioned to have Bot Defense.
- A remote logging pool of your DCDs that is connected to a virtual server deployed over a load balancing BIG-IP device.
- Web Application Security is active for DCD services (see)
The following procedure is for Bot
Defense profiles configured to BIG-IP devices version 14.1 or later. For logging bot
request information from earlier versions of BIG-IP, see
Configuring logging for DoS Protection and Network
Security
.You
can view bot request information by attaching a logging profile to the virtual servers
that host your Bot Defense profile. To access Bot Defense information, you need to configure the
BIG-IP system to send log information to BIG-IQ. This is done by:
- Creating a log publisher and pin it to your BIG-IP device(s)
- Creating and attaching a bot request logging profile in Shared Security
- Deploying your changes over your BIG-IP device(s)
For more details about specific settings within the logging profile, see Configure logging for Bot Defense requests
.
- Click.
- ClickCreateto create a remote bot logging profile.
- Type a uniqueNamefor this logging profile.
- On the left, clickBOT DEFENSE.
- ForStatus, select theEnabledcheck box.The screen displays the Bot Defense request logging properties.
- From theRemote Publisherlist, select the logging publisher for your DCD pool.
- Enable the for the appropriate request types of logging in the remaining fields.
- When you are done, clickSave & Close.
- Attach the new logging profile to a Shared Security virtual server.
- Go to.
- Select the virtual server that hosts your Bot Defense profile.
- From theLogging Profilesfield, select the logging profile created in step 6, and use the arrow to move it to theSelectedlist.
- ClickSave & Close.
- Repeat step 6 for any additional virtual servers that host Bot Defense profiles.
- Deploy your new pool, log destinations and log publisher over your BIG-IP device.
- Go to.
- In theDeploymentslist at the bottom half of the screen and clickCreate.
- In theNamefield add a unique name.
- Ensure thatSourceandSource Scopefields are markedCurrent ChangesandAll Changes, respectively.
- From the Target Devices list, select the host BIG-IP device(s) over which to deploy changes.
- ClickCreate.The deployment is added the to Evaluations list.
- Once the evaluation is complete, click the box next to the deployment name and clickDeploy.
The new local traffic objects are deployed over the BIG-IP device. - Deploy changes to your Shared Security virtual server.
- Go to.
- Repeat steps 10b-g.The new logging profile on your Shared Security virtual server is now deployed over the BIG-IP device.
You can now monitor detected bot requests from the bot
request log, from
.Edit logging profiles
You can edit logging profiles to change the kind of
information the system should log for objects that support logging.
- Click.
- Click the name of a logging profile on the Logging Profiles screen.The logging profile properties screen opens.
- Modify the properties as needed.Logging profile properties are described in theCreate logging profilessection ofBIG-IQ Centralized Management: Securityonsupport.f5.comfor configuration information.
- If the Device Specific area is shown, click the name of a default logging profile for a particular BIG-IP device to review its settings.This area is displayed only for default logging profiles on the BIG-IP device, such asLog all requestsandglobal-network.
- If the Device Specific area is shown, click theglobal-networklogging profile for an individual BIG-IP device to modify the logging profile settings for that device.The settings you can modify are a subset of those available when you are creating a logging profile. You can modify only theglobal-networklogging profile in this way.
- Review and add or modify the other logging profile properties as appropriate.The other logging profile properties are described in theCreate logging profilessection ofBIG-IQ Centralized Management: Securityonsupport.f5.com.
