If you have administrative access, you can view the Web Application Security settings for multiple applications on the Web Application Security dashboard
Web Application Security
- Application Traffic MetricsApplication response time indicates the time (in ms) it takes an application server to respond once it receives a request.HTTP transactions include the entire process from when a client sends an HTTP request to the application server, until the client receives a response.Concurrent connections indicate the number of connections that are open at the same time, either on the client-, or server- side.You must have Web Application Security services installed on your application management devices in order to view security data. The BIG-IP device hosting these services must have AVR provisioned with version 22.214.171.124, or later, to view data.To view application health or traffic data, your application must have be managed by a BIG-IP device version 126.96.36.199 or later with the following device configuration:
BIG-IP devices earlier than version 188.8.131.52 do not collect data that supports metric alerts. Applications that are managed by earlier versions of a BIG-IP device do not receive metric alerts.

- Summary Bar FiltersClick this area to filter the list data by value in descending order.This automatically filters the screen list.
- Click the application's name to open the single application dashboard.
- Alert Concept definitionThe system triggers alerts based on stateful and stateless data that is collected from the various system elements that are monitored. Once triggered, the alert remains active until its status changes.The following alert rule set does not apply to the BIG-IP VE devices in a service scaling group. The default rules do apply to the load balancer BIG-IP device in a service scaling group.
- You can adjust the Warning and Critical threshold values for enabled metrics.A metric threshold violation must be sustained for 5 minutes to trigger an alert. A subsequent alert is triggered once another threshold is crossed (either an increase or decrease in severity, or cleared).To ensure that metric conditions are improving, metrics are declining in severity (critical to warning), or cleared, an alert is triggered only when the value is sustained for five minutes at ten percent below the threshold value. For example, if a threshold value is configured for greater than 60 percent, a declining severity must be sustained at 54 percent or less to trigger an alert.
- ClickSaveat the bottom of the screen, or clickSave & Closeto save and return to the Alert Rules screen.
- Go to.MonitoringDASHBOARDSDDoSProtection Summary

- Locate the ATTACKS area at the top left side of the screen to view a summary of all ongoing DDoS attacks.
- To isolate attacks by severity, select one of the severity levels from ATTACK SEVERITY.
- The Warning alert. The attack's details indicate that an non-mitigated attack would have a moderate impact on your protected objects.
- The Critical alert. The attack's details indicate that a non-mitigated attack would have a critical impact on your protected objects
- To filter attacks by protection mode, specify how to view them:
- ClickMitigatedto view attacks detected by a DoS profile that is configured to mitigate or block traffic recognized at an attack.
- ClickNot Mitigatedto view attacks detected by a DoS profile that is configured to monitor traffic recognized as an attack.
- Go to.MonitoringDASHBOARDSL7 SecurityThis displays all monitored objects.
- To display the attacks list, click ATTACKS at the top left of the screen.
- Select an attack from the Attack ID column.The screen displays attack details and statistics about the attack vectors, BIG-IP devices, and protected objects. By default, the statistics at the bottom of the screen display transaction data from the virtual server(s) that reported the attack.

- Go to.MonitoringDASHBOARDSSSL OrchestratorSSLO OverviewThe overview screen displays tiles with current information about your SSLO configurations.
- If you are creating the filter by directly entering text into the Query Expression area, use the following syntax for that query text.
- You express elements of the filter query as key value pairs, separated by a colon, such asprofile_name:"MyCurrentProfile".
- You can use the following operators within a filter query.OperatorUsage ExampleANDThis:p1 AND bar:(A AND B AND "another value")AND NOTAND NOT qux:errorORname:"this is a name" OR bar:(A OR B OR C)OR NOTOR NOT qux:error*support_id:*123*. This operator can only be used for text fields.
- You must enclose values that have spaces within quotation marks, such askey:"two words".
- You can query any field for more than one value by enclosing the values with parentheses, such askey:(a b "two words"). In this case, the default operator is OR.
- Only pre-defined values are allowed for fields with a type of multi-value. These values are listed in the Query Parameters area, in the list next to the relevant field.
- Values with a type of date accept valid date formats, such as'Oct 30, 2017 00:00:00'.
- Values of the date range type accept input in the format of[min_date...max_date], such as'[Oct 30, 2017 00:00:00...Oct 30, 2017 06:00:00]'. The date range might also contain only minimum without maximum, and the reverse, such as'[Oct 30, 2017 00:00:00...]'or'[...Oct 30, 2017 00:00:00]'.
- Values of the numeric range type accept input in the format of[min...max], such as'[1...100]'. The numeric range might also contain only minimum without maximum, and the reverse, such as'[1...]'or'[...100]'.
- You must include the full path to the policy in a policy name, such as/Common/MyPolicy.
You can identify the status of protected objects and BIG-IP devices that have reported DoS attacks. This way you can evaluate the performance impact of the attack, and whether changes to your security policy or DoS profile are required.
