ASA FirePOWER模块(也称为ASA SFR)提供下一代防火墙服务,包括下一代IPS (NGIPS)、应用可视性与可控性(AVC)、URL过滤和高级恶意软件防护(AMP)。您可以在单情景或多情景模式下以及在路由或透明模式下使用该模块。本文档介绍ASA 5585-X硬件模块上FirePOWER (SFR)模块的必备条件和安装过程。它还提供了向FireSIGHT管理中心注册SFR模块的步骤。
本文档中的说明要求访问特权EXEC模式。要访问特权执行模式,请输入enable命令。如果未设置密码,只需按Enter键。

要在ASA上安装FirePOWER服务,需要以下组件:
假设ASA SSM始终占用ASA 5585-X机箱中的两个插槽之一,如果您有一个除FirePOWER (SFR)服务SSP以外的硬件模块,例如SSP-CX(情景感知)或AIP-SSM(高级检查和防御安全),则必须卸载另一个模块以留出SSP-SFR的空间。在移除硬件模块之前,请运行以下命令以关闭模块:
ciscoasa# hw-module module 1 shutdown
1. 从Cisco.com将ASA FirePOWER SFR模块初始引导映像下载到可从ASA FirePOWER管理接口访问的TFTP服务器。镜像名称类似于“asasfr-boot-5.3.1-152.img”
2. 从Cisco.com将ASA FirePOWER系统软件下载到可从ASA FirePOWER管理接口访问的HTTP、HTTPS或FTP服务器。
3. 重新启动SFR模块
选项1:如果您没有SFR模块的密码,则可以从ASA发出以下命令以重新启动模块。
ciscoasa# hw-module module 1 reload
Reload module 1? [confirm]
Reload issued for module 1
选项2:如果您有SFR模块的密码,可以直接从命令行重新启动传感器。

This sensor must be managed by a Defense Center. A unique alphanumeric registration
key is always required. In most cases, to register a sensor to a Defense Center,
you must provide the hostname or the IP address along with the registration key.
'configure manager add [hostname | ip address ] [registration key ]'
However, if the sensor and the Defense Center are separated by a NAT device, you
must enter a unique NAT ID, along with the unique registration key. 'configure
manager add DONTRESOLVE [registration key ] [ NAT ID ]'
Later, using the web interface on the Defense Center, you must use the same
registration key and, if necessary, the same NAT ID when you add this
sensor to the Defense Center.

要管理ASA FirePOWER模块和安全策略,您必须向FireSIGHT管理中心注册该模块。不能使用FireSIGHT管理中心执行以下操作:
通过创建识别特定流量的服务策略,可将流量重定向至ASA FirePOWER模块。要将流量重定向至FirePOWER模块,请执行以下步骤:
首先,使用access-list命令选择流量。在以下示例中,我们重定向来自所有接口的所有流量。您还可以针对特定流量执行此操作。
ciscoasa(config)# access-list sfr_redirect extended permit ip any any
以下示例展示如何创建类映射并匹配访问列表上的流量:
ciscoasa(config)# class-map sfr
ciscoasa(config-cmap)# match access-list sfr_redirect
您可以在被动(“仅监控”)或内联部署中配置设备。您无法在ASA上同时配置仅监控模式和正常内联模式。只允许一种类型的安全策略。
在内联部署中,丢弃不需要的流量并执行策略应用的任何其他操作后,流量将返回到ASA进行进一步处理和最终传输。以下示例展示如何创建策略映射并在内联模式下配置FirePOWER模块:
ciscoasa(config)# policy-map global_policy
ciscoasa(config-pmap)# class sfr
ciscoasa(config-pmap-c)# sfr fail-open
在被动部署中,
如果要在被动模式下配置FirePOWER模块,请使用monitor-only关键字,如下所示。如果不包含关键字,则在内联模式下发送流量。
ciscoasa(config-pmap-c)# sfr fail-open monitor-only
最后一步是应用策略。您可以全局应用策略或在接口上应用策略。您可以通过对接口应用服务策略以覆盖此接口的全局策略。
global关键字将策略映射应用于所有接口,而interface将策略应用于一个接口。 仅允许有一个全局策略。在以下示例中,全局应用策略:
ciscoasa(config)# service-policy global_policy global
