Active firewall policy rule properties

This table describes the rule properties shown for a firewall policy that is active on a BIG-IP device.
Column
Description
#
Specifies the evaluation order of the rule within the policy. Rules are evaluated from the lowest number to the highest. If a rule is contained within a rule list, it will be numbered after the decimal point. For example, a policy with 3 rules, followed by a rule list containing 2 rules, followed by another rule outside of the rule list, would be numbered as:
1, 2, 3, 4, 4.1, 4.2, 5
. In the example, 4 represents the rule list, and 4.1 and 4.2 are the evaluation order of the rules within that rule list.
Rule Name
Specifies the name of the rule. This contains a reference to the rule list when the row contains a rule list. You can click the rule name for more information.
Rule List Name
Specifies the name of the rule list that contains one or more rules. This is blank when the row contains a rule.
UUID
Specifies the universal unique identifier (UUID) associated with the rule. You can use the UUID to search for a rule in a policy. You must enable this feature on the BIG-IP device for UUIDs to be assigned to rules on that device.
Action
Specifies the action taken when the rule is matched, such as whether it is accepted or rejected.
Protocol
Specifies the IP protocol used by the rule to compare against the packet.
Log
Specifies whether the firewall software should write a log entry for any packets that match this rule.
State
Specifies the activity state of the rule, such as whether it is enabled or disabled.

Monitoring Firewall Rules

About firewall rule monitoring

In BIG-IQ Centralized Management, you can monitor:
  • Firewall rule statistics, such as the number of times inbound network traffic matches a firewall rule on a BIG-IP device (also referred to as a firewall rule hit count) as well as the rule overlap status.
  • Firewall rule compilation statistics for a set of rules associated with a firewall context on a BIG-IP device.

Monitoring firewall rule statistics and hit counts

You can monitor firewall rule statistics and hit counts on one or more BIG-IP devices using Network Security monitoring.
Firewall rule statistics are collected for the rules in the enforced policy associated with a firewall, but not the rules in a staged policy.
If a virtual server, route domain or self IP is created using the BIG-IQ system, firewall statistics cannot be collected until the changes are deployed to the device and reimported.
  1. Log in to the BIG-IQ system with your user name and password.
  2. At the top left of the screen, select
    Network Security
    from the BIG-IQ menu.
  3. Click
    Monitoring
    .
  4. Click
    Firewall Rule Statistics
    .
    The Firewall Rule Statistics screen opens and displays a list of firewall contexts, including their name, partition, type, and on what BIG-IP device they occur.
  5. Click the name of the firewall context to monitor.
  6. The Firewall Rule Statistics page for that firewall context displays.
    The following information is listed in the named columns for each firewall rule on the BIG-IP device:
    • Rule Name specifies the name of the rule used in the policy. If not listed, the rule is not running.
    • Rule List Name specifies the name of the rule list if the rule is in a rule list.
    • Rule specifies the name of the rule within a rule list. If the rule is not in a rule list, this field is blank.
    • Overlap Status specifies whether the rule overlaps with another rule.
    • Hit Count specifies the number of times the rule has been matched.
    • Last Hit Time specifies when the rule was last matched.

Monitoring firewall rule compilation statistics

You can monitor rule compilation statistics on one or more BIG-IP devices using Network Security monitoring. This information is similar to what is displayed when using the
tmsh show security firewall container-stat
 command.
If a firewall context references a policy that is both staged and enforced, there will be two entries in the compilation statistics: one for the enforced policy and one for the staged policy.
  1. Log in to the BIG-IQ system with your user name and password.
  2. At the top left of the screen, select
    Network Security
     from the BIG-IQ menu.
  3. Click
    Monitoring
    .
  4. Click
    -[[Firewall ]]-+[[+[[Firewall ]]+]]+Compilation Statistics
    .
    The Firewall Compilation Statistics screen opens and displays the list of BIG-IP devices managed by the BIG-IQ system, including their network name, IP address, and BIG-IP device version.
  5. Click the name of the BIG-IP device to monitor.
  6. The Firewall Compilation Statistics page for that BIG-IP device displays.
    Depending on the version of the BIG-IP device, the following information, or a subset of this information, may be listed in the named columns for the one or more firewall rules within the specified firewall context on the BIG-IP device:
    • Context Name
       specifies the context name associated with the one or more rules, such as
      /Common/global-firewall-rules
      .
    • Context Type
       specifies the firewall context type associated with the one or more rules, such as global or self IP.
    • Policy Name
       specifies the name of the policy associated with the one or more rules.
    • Policy Type
       specifies type of policy associated with the one or more rules, such as enforced or staged.
    • Rule Count
      Specifies the number of rules compiled for this BIG-IP device context, such as 30. This count includes rules in rule lists as well as rules that are not in rule lists.
    • Compile Duration
       specifies the amount of time required to compile the rules, expressed as
      hours:minutes:seconds
      .
    • Overlap Check Duration
       specifies the amount of time required to check overlapping rules, expressed as
      hours:minutes:seconds
      .
    • Size
       specifies the size of the compiled rules in bytes.
    • Max Memory
       specifies the maximum amount of memory consumed by the rules in bytes.
    • Activation Time
       specifies when the rules are activated and available for use.

Monitoring Network Security Events

Configure viewing of Network Security events

Before you configure monitoring of Network Security events, you need to ensure that the Network Security service is running 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 Network Security service is not running, click
Activate
 to start it.
If you deactivate the Network Security 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
afm-remote-logging-pool_
big-ipname
 contains the pool member for the specified BIG-IP device.
You configure the collection and viewing of Network Security events so that you can better view and monitor information about your Network Security policies and firewalls. The BIG-IQ Centralized Management system provides a single button configuration process that creates and configures the needed configuration objects. The system creates these 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
The configuration objects are shared among the Shared Security virtual servers that were selected. The objects that are created should not be modified. Modifying these objects could affect the ability of the BIG-IP devices to send Network Security events to the DCD.
  1. Click
    Configuration
    SECURITY

        All Devices
        .
      • In the Filter field in the upper right, type a text string to use a simple text filter on the events. You can use more complex filters by clicking the filter icon to the left of the Filter field. Note that the simple text filter does not support more complex filter syntax, such as specifying time in minutes and seconds.
    • To change how often the event list is refreshed, select a value in the setting in the upper left.

Create filters for Network Security events

You create Network Security event filters so you can save the filters you use frequently to search for events, and not have to recreate them each time.
  1. Click
    Monitoring
    EVENTS
    Network Security
    Filters
    .
  2. Click
    Add
    .
  3. Type a unique
    Filter Name
    .
  4. Create the filter using the Query Parameters area or by entering the query directly into the Query Expression area.
    In most cases, you should create the filter query using the Query Parameters area and only edit it directly if you need to refine it further.
  5. If you are creating the filter using the Query Parameters area, supply those parameter settings you want to be part of the filter.
    Note that as you enter parameter settings, they are used to construct the filter query in the Query Expression area. You can also edit the filter query directly as described in the following step.
  6. 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 as
      profile_name:"MyCurrentProfile"
      .
    • You can use the following operators within a filter query.
      Operator
      Usage Example
      AND
      This:p1 AND bar:(A AND B AND "another value")
      AND NOT
      AND NOT qux:error
      OR
      name:"this is a name" OR bar:(A OR B OR C)
      OR NOT
      OR NOT qux:error
      *
      support_id:*123*
      . This operator can only be used for text fields.
    • You must enclose values with spaces with quotation marks, such as
      key:"two words"
      .
    • You can query any field for more than one value by enclosing the values with parentheses, such as
      key:(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
      .
  7. You can enter fields in the Query Expression area that are not shown in the Query Parameters area by discovering them in the user interface.
    1. Click the event row to show the event details in the lower part of the screen.
    2. Hover over a label name in that area to see the field name to use in the query expression. For example, hovering over Signature Name in the lower screen shows that the matching field is
      sig_name
      .
  8. Save your work.

    .
  4. Create the filter using the Query Parameters area or by entering the query directly into the Query Expression area.
    In most cases, you should create the filter query using the Query Parameters area and only edit it directly if you need to refine it further.
  5. If you are creating the filter using the Query Parameters area, supply those parameter settings that you want to be part of the filter.
    Note that as you enter parameter settings, they are used to construct the filter query in the Query Expression area. You can also edit the filter query directly as described in the following step.
  6. 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 as
      profile_name:"MyCurrentProfile"
      .
    • You can use the following operators within a filter query.
      Operator
      Usage Example
      AND
      This:p1 AND bar:(A AND B AND "another value")
      AND NOT
      AND NOT qux:error
      OR
      name:"this is a name" OR bar:(A OR B OR C)
      OR NOT
      OR NOT qux:error
      *
      support_id:*123*
      . This operator can only be used for text fields.
    • You must enclose values with spaces with quotation marks, such as
      key:"two words"
      .
    • You can query any field for more than one value by enclosing the values with parentheses, such as
      key:(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

Managing Firewall Packet Flow Reports

About firewall packet flow reports

You create and review packet flow reports to inspect the currently active packet flows on BIG-IP devices. You can use these reports to determine if a packet flow meeting certain parameters is active on the BIG-IP devices. You can combine using the packet flow reports with packet trace reports to see if a BIG-IP device may be blocking certain flows at a firewall.
You can also review prior packet flow reports. The BIG-IQ Centralized Management Packet Flows feature is similar to the Flow Inspector feature in the Advanced Firewall Manager (AFM) on the BIG-IP device.

Viewing Web Application Security Event Logs

About event log viewing

You can view Web Application Security event logs to review applications and server activities. BIG-IQ® Centralized Management enables a single view of all filters and log entries (and details for each entry) from multiple BIG-IP® devices.
You use tags and filters to allow you to select which events to view.
  • Filters allow you to select the events to view by constructing a query that the events must match.
  • You can assign tags to events to label them, so that you can use that label in queries.
Before you can view events, event logging must be configured as follows.
  1. Discover and activate a BIG-IQ Data Collection Device.
  2. Configure a BIG-IP device to collect event logs and send them to the BIG-IQ Centralized Management Data Collection Device. Part of this configuration includes a virtual server configured with a logging profile.
  3. Configure a logging profile for Web Application Security, assign it to a virtual server, and deploy it to the BIG-IP device that has been configured to collect log events. A
    logging profile
     is used to determine which events the system logs, and where, and the format of these events. It then directs security events to a BIG-IQ Data Collection Device, and the BIG-IQ Centralized Management system retrieves them from that node.

View event logs and define filters and tags

You can review Web Application Security events on applications and servers from one or more BIG-IP devices. By default, the events are filtered to show only illegal requests. You can use the Web Application Security Event Logs screen to define tags and filters to help you find meaningful events.

Reports can be for a single BIG-IP device or can contain aggregated data for multiple BIG-IP devices (that are of the same BIG-IP device version).
Network Firewall, DoS and IP Intelligence reports can be created. Analytic reports provide detailed metrics about application performance such as transactions per second, server and client latency, request and response throughput, and sessions. Metrics are provided for applications, virtual servers, pool members, URLs, specific countries, and additional detailed statistics about application traffic running through one or more managed devices. You can view the analytics reports for a single device, view aggregated reports for a group of devices, and create custom lists to view analytics for only specified devices.

Reporting for BIG-IQ Web Application Security

You can use BIG-IQ Web Application Security Reporting to view reports for managed BIG-IP devices that are provisioned for Application Visibility and Reporting (AVR). Similar to the availability of the AVR reporting on a single device, you have the ability to get visibility into application traffic passing through a single managed BIG-IP device or an aggregated system (aggregated data for multiple BIG-IP devices.
You can generate reports and charts in the following areas:
  • Application. You can view information about requests based on applications (iApps), virtual servers, security policies, attack types, violations, URLs, client IP addresses, IP address intelligence (reputation), client countries, severities, response codes, request types, methods, protocols, viruses detected, usernames, and session identification numbers.
  • Anomalies. You can view charts of statistical information in graphs about anomaly attacks, such as brute force attacks and web scraping attacks. You can use these charts to evaluate traffic to the web application, and to evaluate the vulnerabilities in the security policy.
  • DoS. If you have configured DoS protection on the BIG-IP system, you can view charts and reports that show information about DoS attacks and mitigations in place on the system.
