Cisco ASA 5585-X 高密度状态式防火墙数据手册说明书
Data SheetCisco ASA 5585-X Stateful FirewallToday’s enterprise networks struggle to keep up with a mobile workforce. Users expect on-demand access from their many devices, even as applications multiply and push performance levels. And of course security remains a priority. How do you scale and still preserve the integrity of the network? Start with the Cisco® ASA 5585-X Firewall, a compact yet high-density firewall that delivers tremendous scalability, performance, and security in a two-rack-unit (2RU) footprint.Using a single firewall blade, the Cisco ASA 5585-X meets the growing needs of dynamic organizations by providing eight times the performance density, very high VPN session counts, twice as many connections per second, and four times the connection capacity of any competitive firewall.Firewall FeaturesSupport for Layer 3 and Layer 4 stateful firewall inspection features, including access control and network address translation, enables organizations to keep existing stateful inspection policies that are essential for compliance regulations and securing critical data center resources.In addition to comprehensive stateful inspection capabilities, Layer 7 next-generation policies act intelligently on contextual information. Cisco AnyConnect® technology provides information on the type and location, and endpoint posture of a mobile device before it accesses the network, so that administrators can maintain high levels of network visibility, protection and control. Threat intelligence feeds from Cisco Collective Security Intelligence (CSI) use the global footprint of Cisco security deployments to analyze approximately one-third of the world’s Internet traffic for near-real-time protection from new and emerging threats.Flexible Deployment OptionsThe Cisco ASA 5585-X supports two hardware blades in a single 2RU chassis. The bottom slot (slot 0) hosts the ASA stateful inspection firewall module, while the top slot (slot 1) can be used for adding up to two Cisco ASA 5585-X I/O modules for high interface density for mission-critical data centers that require exceptional flexibility and security.ClusteringUsing Cisco ASA Software Release 9.0 and later, customers can combine up to 16 Cisco ASA 5585-X firewall modules in a single cluster for up to 640 Gbps of throughput, 2 million connections per second, and more than 100 million concurrent connections. This “pay as you grow” model enables organizations to purchase what they need today and dynamically add more when their performance needs grow. To protect high-performance data centers from internal and external threats, the cluster can be augmented by adding IPS modules.Cisco ASA software clustering delivers a consistent scaling factor, irrespective of the number of units in the cluster, for a linear and predictable increase in performance. Complexity is reduced, as no changes are required to existing Layer 2 and Layer 3 networks. Support for data center designs based on the Cisco Catalyst® 6500 Series Virtual Switching System (VSS) and the Cisco Nexus virtual PortChannel (vPC) as well as the Link Aggregation Control Protocol (LACP) provides high availability (HA) with better network integration.For operational efficiency, Cisco ASA clusters are easy to manage and troubleshoot as a single entity. Policies pushed to the master node are replicated across all the units within the cluster. The health, performance, and capacity statistics of the entire cluster, as well as individual units within the cluster, can be assessed from a single management console. Hitless software upgrades are supported for ease of device updates.Clustering supports HA in both active/active and active/passive modes. All units in the cluster actively pass traffic, and all connection information is replicated to at least one other unit in the cluster to support N+1 HA. In addition, single and multiple contexts are supported, along with routed and transparent modes. A single configuration is maintained across all units in the cluster using automatic configuration sync. Clusterwide statistics are provided to track resource usage.Cisco TrustSec IntegrationUsing Cisco ASA Software Release 9.0 and later, the Cisco ASA 5585-X provides context awareness through the integration of identity-based firewall security and Cisco TrustSec® security group tags for enhanced visibility and control. Identity-based firewall security provides more flexible access control to enforce policies based on user and group identities and the point of access. Administrators can write policies that correspond to business rules, a process that increases security, enhances ease of use, and requires fewer policies to manage. Similarly, Cisco TrustSec integration enables security group tags to be embedded into the network, providing administrators with the ability to develop and enforce better, more precise policies.Cut Costs While Improving Performance and SecurityThe Cisco ASA 5585-X Next-Generation Firewall delivers superior scalability, performance, and security to handle high data volumes without sacrificing performance. Most firewalls require up to 16RUs and 5100 watts to scale to the level of performance that the Cisco ASA 5585-X achieves with only 2RUs and 785 watts. This performance helps enterprises meet the increasing demands for network connectivity without the need to invest in additional data center space and incur the corresponding maintenance costs.Based on tests conducted by Cisco, the Cisco ASA 5585-X significantly reduces initial procurement costs by 80 percent, power consumption costs by 85 percent, and rack space requirements by 88 percent in addition to significant reductions in overall integration and management complexity and costs. In addition, you can install up to two firewall modules in a single Cisco ASA 5585-X chassis, providing scalability to 80 Gbps.Table 1 gives the capabilities of the four Cisco ASA 5585-X models.Table 1. Cisco ASA 5585-X Next-Generation Firewall Capabilities and CapacitiesEdge Edge Data center Data centerUnlimited Unlimited Unlimited Unlimited1 Maximum throughput with UDP traffic measured under ideal test conditions.2“Multiprotocol” refers to a traffic profile consisting primarily of TCP-based protocols and applications like HTTP, SMTP, FTP, IMAPv4, BitTorrent, and DNS.3 Available for the firewall feature set.4 VPN throughput and maximum peers depend on the ASA device configuration and VPN traffic patterns, including average packet size.

cisco pix防火墙基本配置命令使用手册
cisco pix防火墙基本配置命令使用任何企业安全策略的一个主要部分都是实现和维护防火墙，因此防火墙在网络安全的实现当中扮演着重要的角色。
防火墙通常位于企业网络的边缘，这使得内部网络与internet之间或者与其他外部网络互相隔离，并限制网络互访从而保护企业内部网络。
设置防火墙目的都是为了在内部网与外部网之间设立唯一的通道，简化网络的安全管理。
在众多的企业级主流防火墙中，cisco pix防火墙是所有同类产品性能最好的一种。
cisco pix 系列防火墙目前有5种型号pix506，515，520，525，535。
其中pix535是pix 500系列中最新，功能也是最强大的一款。
它可以提供运营商级别的处理能力，适用于大型的isp等服务提供商。
但是pix特有的os操作系统，使得大多数管理是通过命令行来实现的，不象其他同类的防火墙通过web管理界面来进行网络管理，这样会给初学者带来不便。
本文将通过实例介绍如何配置cisco pix防火墙。
在配置pix防火墙之前，先来介绍一下防火墙的物理特性。
防火墙通常具有至少3个接口，但许多早期的防火墙只具有2个接口；当使用具有3个接口的防火墙时，就至少产生了3个网络，描述如下：ø内部区域（内网）。
内部区域通常就是指企业内部网络或者是企业内部网络的一部分。
它是互连网络的信任区域，即受到了防火墙的保护。
ø外部区域（外网）。
外部区域通常指internet或者非企业内部网络。
它是互连网络中不被信任的区域，当外部区域想要访问内部区域的主机和服务，通过防火墙，就可以实现有限制的访问。
ø停火区（dmz）。
停火区是一个隔离的网络，或几个网络。
位于停火区中的主机或服务器被称为堡垒主机。
一般在停火区内可以放置web服务器，mail服务器等。
停火区对于外部用户通常是可以访问的，这种方式让外部用户可以访问企业的公开信息，但却不允许他们访问企业内部网络。
注意：2个接口的防火墙是没有停火区的。

思科防火墙基本配置指导
思科防火墙基本配置指导下面我讲一下一般用到的最基本配置1、建立用户和修改密码跟Cisco IOS路由器基本一样。
2、激活以太端口必须用enable进入，然后进入configure模式PIX525>enablePassword:PIX525#config tPIX525(config)#interface ethernet0 autoPIX525(config)#interface ethernet1 auto在默然情况下ethernet0是属外部网卡outside, ethernet1是属内部网卡inside, inside在初始化配置成功的情况下已经被激活生效了，但是outside必须命令配置激活。
3、命名端口与安全级别采用命令nameifPIX525(config)#nameif ethernet0 outside security0PIX525(config)#nameif ethernet0 outside security100security0是外部端口outside的安全级别（0安全级别最高）security100是内部端口inside的安全级别,如果中间还有以太口，则security10，security20等等命名，多个网卡组成多个网络，一般情况下增加一个以太口作为DMZ(Demilitarized Zones非武装区域)。
4、配置以太端口IP 地址采用命令为：ip address如：内部网络为：192.168.1.0 255.255.255.0外部网络为：222.20.16.0 255.255.255.0PIX525(config)#ip address inside 192.168.1.1 255.255.255.0PIX525(config)#ip address outside 222.20.16.1 255.255.255.05、配置远程访问[telnet]在默然情况下，PIX的以太端口是不允许telnet的，这一点与路由器有区别。

Pix系列产品默认只有两个端口及0和1，DMZ端口都是另外添加的模块，DMZ端口的默认安全级别50，配置DMZ接口的地址和配置inside和outside类似
配置外接口地址
Pix(config)#ip address inside 1.1.1.1 255.255.255.0
配置内接口地址
Pix(config)#interface ethernet0 auto
激活外端口
Pix(config)#interface ethernet1 auto
激活内端口 （默认端口是出于shutdown状态的）
Pix(config)#ip address dmz 3.3.3.3 255.255.255.0
Pix(config)# interface gb-ethernet0 1000auto 激活DMZ端口，DMZ的端口号需要您用show
running-config命令查看，如：
Pix(config)#show running-config
防火墙的nat和global是同时工作的，nat定义了我们要进行转换的地址，而global定义了要被转换为的地址，这些配置都要在全局配置模式下完成，
2.2、Nat配置如下：
Pix(config)#nat (inside) 1 0 0
上面inside代表是要被转换得地址，
1要和global 后面的号对应，类似于访问控制列表号，也是从上往下执行，
Firewall(config)#access-group outside in interface outside
必须将用access-group命令将访问控制列表应用到外端口，上述完成后就可以从外网上来访问服务器了。
5、防火墙上常用的show命令
Firewall (config) #show interface 查看所有端口的状态，端口是否出于连接状态
查看防火墙的当前配置文件 来自二、防火墙配置简介 1、以前的防火墙的系统版本是6.3以下，在这种版本里面不能用“tab”键补齐命令，而且用“？”来查询命令也很不方便；
目前的ASA5500的系统版本为7.0以上，和路由器的命令相同，可以用“tab”键补齐命令，可以用“？”来查看参数、同样也可以在全局模式用show命令。
firewall（config）#telnet 192.168.10.0 255.255.255.0 inside 允许内网此网断内的机器Telnet到防火墙
配置从外网远程登陆到防火墙
Firewall（config）#domain-name
firewall（config）# crypto key generate rsa
CPU utilization for 5 seconds = 1%; 1 minute: 1%; 5 minutes: 1%
如果内部有终端中毒（或利用Ｐ２Ｐ下载）向网关送大量的数据包，会导致防火墙只能来处理病毒机器的请求，而无暇顾及正常流量，导致正常用户不能上网，要找到不正常终端可以利用show conn来查看
上述命令便将内部的web服务器放到了公网上面，但外面的用户并不能访问到，因为防火墙的外界口安全级别最低，从低安全级别到高安全级别主动发起的链接请求需要我们在防火墙上利用访问控制列表手动放开，如下：
Firewall(config)#access-list outside permit tcp any host 222.128.124.1 eq 80
一、Cisco Pix日常维护常用命令
1、Pix模式介绍
“>”用户模式
firewall>enable
由用户模式进入到特权模式
password:
“#”特权模式
firewall#config t
由特权模式进入全局配置模式
“（config）#”全局配置模式
firewall(config)#
firewall（config）# interface ethernet0 100full
激活外端口
firewall（config）# interface gb-ethernet0 1000auto
激活内端口
2、telnet、ssh、web登陆配置及密码配置
防火墙默认是不允许内/外网用户通过远程登陆或WEB访问的，需要相应得开启功能。
Fierwall(config)#clear arp
清除ＡＲＰ表
Firewall(config)#clear xlate
清除内部所有地址的转换项，网络中断一下
Firewall(config)#clear xlate local 192.168.40.69
清除内部具体一台机器的转换项
Firewall(config)#show runnint-config
firewall(config)#hostname firewall
设备名称
firewall（config）#ip address outside 1.1.1.1 255.255.255.0
内外口地址设置
firewall（config）#ip address inside 172.16.1.1 255.255.255.0
t
全局配置模式：当您看到（config）#时，表示现在处于全局配置模式，可以对防火墙的设置进行修改。
在“>”、“#”、“（config）#”左侧显示的为设备的名称。
2、
1）、防火墙接口配置
Pix配置
Pix>enable
进入特权模式
Pix#config
t
进入全局配置模式
Pix(config)#ip address outside 222.128.1.1 255.255.255.0
由用户模式进入特权模式的口令
firewall（config）#passrd cisco
ssh远程登陆时用的口令
firewall（config）#username Cisco password Cisco
Web登陆时用到的用户名
firewall（config）#http enable
打开http允许内网10网断通过http访问防火墙
interface ethernet0 "outside" is up, line protocol is up 端口和协议都出于“ｕｐ”状态，正常。
pixfirewall# sh cpu usage
查看ＣＰＵ的使用情况，如果ＣＰＵ的使用情况超过６０％是不正常的，说明内部有ＰＣ对外占用了设备大量资源
做完上面的配置内网用户就可以上网了，内部有３层交换机且划分了Ｖｌａｎ，若要保证每个Ｖｌａｎ都能够上网，还要在防火墙上指回到其他ＶＬａｎ的路由，如：
Firewall (config) # route inside 192.168.20.0 255.255.255.0 172.16.1.2
4、内网服务器映射
firewall（config）#ssh 0.0.0.0 0.0.0.0 outside
允许外网所有地址可以远程登录防火墙，也可以定义一格具体的地址可以从外网登陆到防火墙上，如：
firewall（config）#ssh 218.240.6.81 255.255.255.255 outside
firewall（config）#enable password cisco
防火墙的几种工作模式：
用户模式：如果您看到>那么现在代表是在用户模式下，在用户模式下只有简单的命令可以操作。由用户模式进入特权模式的命令为：enable
特权模式：如果您看到当前的位置显示#那么您处于特权模式下，在特权模式下用户可以查看所有信息，而前可以进入全局配置模式对防火墙配置进行修改。由特权模式进入全局配置模式下的命令为：config
sh run
: Saved
:
PIX Version 6.3(5)
interface ethernet0 100full
interface ethernet1 auto
interface gb-ethernet0 1000auto
新添加的DMZ端口
2）、防火墙nat设置
2.1、内网用户要上网，我们必须对其进行地址转换，将其转换为在公网上可以路由的注册地址，
fierwall(config)#nat (inside) 1 192.168.20.0 255.255.255.0
firewall (config) # global
(outside) 1 interface
对进行nat转换得地址转换为防火墙外接口地址
firewall (config) # route 0.0.0.0 0.0.0.0 1.1.1.2 指一条默认路由器到ＩＳＰ
Firewall(config)#show conn local 192.168.40.69
查看具体一个ＩＰ地址的链接项：
Firewall(config)#show version 查看防火墙的硬件信息
Firewall(config)#show xlate
查看内部地址时否转换成外端口地址来上网
3、保证防火墙能上网还要有以下的配置
firewall（config）#nat （inside）1 0 0
对内部所有地址进行ＮＡＴ转换，或如下配置，对内部固定配置的地址进行ＮＡＴ转化，未指定的不予转发
