防火墙在校园出口安全方案中的应用
简介
本案例介绍了防火墙在校园出口安全方案中的应用。通过分析校园网安全面临的主要问题以及校方在网络访问管理中的常见需求，本案例给出了最典型的2个应用方案，可以解决大多数情况下的校园网安全方案部署。

方案简介
随着教育信息化的加速，高校网络建设日趋完善，在师生畅享丰富网络资源的同时，校园网络的安全问题也逐渐凸显，并直接影响学校的教学、管理、科研等活动。如何构建一个安全、高速的校园网络，已成为高校网络管理者需要迫切解决的问题。
校园网从网络层到应用层的各个层面都面临着不同的安全威胁：
网络边界防护：校园网一般拥有多个出口，链路带宽高，网络结构复杂；病毒、蠕虫的传播成为最大安全隐患；越来越多的远程网络接入，对安全性构成极大挑战。
内容安全防护：无法及时发现和阻断网络入侵行为；需要对用户访问的URL进行控制，允许或禁止访问某些网页资源，规范上网行为；需要防范不当的网络留言和内容发布，防止造成不良的社会影响。
FW作为高性能的下一代防火墙，可以部署在校园网出口，帮助高校降低安全威胁，实现有效的网络管理。FW不仅可以提供安全隔离和日常攻击防范，还具备多种高级应用安全能力，如攻击防范、IPS、防病毒、上网行为审计等，在实施边界防护的同时提供应用层防护。
如图1-1所示，FW作为安全网关部署在校园网出口，提供内、外网互访的安全隔离和防护。FW不仅可以提供传统的基于IP地址的安全策略制定和网络访问控制，还可以提供基于用户的访问控制和行为溯源。这给予了网络管理者极大的灵活性，可以依据网络实际情况选择最高效的管控策略，并减少安全维护的工作量。
图1-1 FW在校园网中的应用
方案一：基于IP地址的策略控制
典型组网
如图1-2所示，FW作为安全网关部署在校园网出口，为校内用户提供宽带服务，为校外用户提供服务器访问服务。由于校园网络是逐步、分期发展起来的，所以出口链路的带宽并不均衡，其中教育网的链路带宽为1G，ISP1的3条链路带宽分别为200M、1G和200M，ISP2的2条链路带宽均为1G。
图1-2 基于IP地址的策略控制组网图
由于学校网络的主要用途是学习和工作，所以在保证内网用户和服务器安全的同时，要合理分配带宽资源，并对网络流量进行负载分担，提升内外部用户的访问体验。校园网的主要需求如下：
负载分担
为了保证内网用户的上网体验，充分利用多条ISP链路，学校希望访问特定ISP网络的流量优先从该ISP对应的出接口转发出去，例如访问教育网的流量优先从GE1/0/1转发，访问ISP2的流量优先从GE1/0/5或GE1/0/6转发。同时，对属于同一ISP的多条链路，可以按照链路带宽或权重的比例进行流量负载分担。为提高转发的可靠性，防止单条链路流量过大导致丢包，各链路间还要实现链路备份。
各ISP链路的传输质量实际上是不同的，其中教育网和ISP2的链路质量较高，可以用来转发对时延要求较高的业务流量（例如远程教学系统的流量），ISP1的链路质量较差，可以用来转发占用带宽大、业务价值小的业务流量（例如P2P流量）。考虑到费用因素，访问其他高校服务器的流量、图书馆内用户的上网流量、所有匹配缺省路由的流量需要从教育网链路转发出去。
由于校内用户自动获得的是同一个DNS服务器地址，所以流量将从同一条ISP链路转发出去。学校希望充分利用其他链路资源，所以要分流部分DNS请求报文到其他ISP链路上。如果只是改变了报文的出接口，还是无法解决后续上网流量集中在一条链路上的问题。所以要将报文发送到不同ISP的DNS服务器上，这样解析后的地址就属于不同的ISP，达到了分流的目的。
学校内部署了DNS服务器提供域名解析服务，不同ISP的用户访问学校网站时，可以解析到属于自己ISP的地址，不会解析到其他ISP的地址，提高访问质量。
由于访问图书馆服务器的流量较大，所以需要部署2台服务器对流量进行负载分担。
地址转换
校内用户访问Internet时需要使用公网IP地址。
校内服务器使用公网IP地址同时为内、外网用户提供服务，例如图书馆服务器、Portal服务器、DNS服务器等。
安全防护
按照网络设备所处的位置划分不同区域，并对各区域间的流量进行安全隔离，控制各区域间的互访权限。例如，允许校内用户访问外网资源，只允许外网用户访问校内服务器的指定端口。
能够防御常见的DDoS攻击（例如SYN flood攻击）和单包攻击（例如Land攻击）。
能够对网络入侵行为进行阻断或告警。
带宽管控
由于带宽资源有限，所以学校希望限制P2P流量占用的带宽比例，并限制每个用户的P2P流量带宽。常见的P2P流量主要来源于下载软件（如迅雷、电驴、BT、Ares、Vuze）、音乐软件（如酷我音乐盒、酷狗、SoulSeek）或视频网站或软件（如百度影音、爱奇艺、搜狐影音）。
溯源审计
为了防止个别校内用户的不当网络行为对学校声誉造成伤害，并做到事后能够回溯和还原事件，需要对校内用户的网络行为进行审计，供日后审查和分析。需要审计的行为主要包括URL访问记录、BBS和微博的发帖内容、HTTP上传和下载行为、FTP上传和下载行为。
学校部署有日志服务器，需要在日志服务器上查看攻击防范和入侵检测的日志，并且能够查看NAT转换前后的IP地址。
业务规划
FW可以满足校园网的所有需求，下面给出具体功能的介绍并结合组网进行业务规划。
网络基础及访问控制配置
FW通过设置安全区域将校园网的各个区域安全隔离，并通过安全策略控制各个区域间的互访权限。
其中，校园网用户处于Trust区域，安全级别最高，可以主动访问所有安全区域；服务器也处于Trust区域，但是通过策略控制服务器仅可以访问外网区域，不可以访问Trust区域内的设备；分别为各ISP创建安全区域，这是为了方便单独控制某两个域间的策略，允许各ISP区域中的设备访问服务器区。同时，为了保证安全区域间多通道协议（例如FTP协议）的正常通信，还需要开启ASPF功能。
表1-1 网络基础配置规划
表1-2 访问控制配置规划
入侵防御
为了防止僵尸、木马、蠕虫的入侵，需要在FW上部署入侵防御功能，对入侵行为进行告警或阻断。为了更好地识别入侵行为，FW还需要定期通过安全中心平台（sec.huawei.com）更新入侵防御特征库。
表1-3 入侵防御配置规划
DNS透明代理
DNS透明代理功能可以修改DNS请求报文的目的地址，实现DNS服务器的重定向。本例中结合策略路由智能选路，可以使DNS请求报文按照链路带宽比例进行转发，由于解析后的服务器地址也属于不同的ISP，所以后续的访问流量也会分担到不同的ISP链路上。
表1-4 DNS透明代理配置规划
智能选路
为了满足校园网出口的流量转发需求，可以在FW上部署策略路由智能选路功能，结合ISP地址集即可实现按照运营商转发流量。此外，对于某些特殊流量的转发需求，可以利用单出口策略路由指导流量从固定的出接口转发。最后，对于没有命中ISP地址集的流量，可以选择链路质量最好的链路转发出去。
表1-5 智能选路配置规划
服务器负载均衡
图书馆的2台服务器对外体现为一台高性能、高可靠性的虚拟服务器，对于用户来说访问的就是虚拟服务器，而并不知道实际处理业务的是其他服务器。为了提升用户访问体验，虚拟服务器向外发布多个ISP的公网IP地址。
表1-6 服务器负载均衡配置规划
智能DNS
智能DNS是指存在私网DNS服务器的情况下，FW对于来自不同ISP的DNS请求进行智能回复，使各ISP的用户能够获得最适合的解析地址，即与用户属于同一ISP网络的服务器地址。
例如，学校内网有一台DNS服务器，上面存放了Portal服务器的域名（www.example.com）和教育网分配的公网地址1.1.15.15，并在FW的GE1/0/2接口上启用智能DNS功能，映射后的地址为ISP1分配的公网地址2.2.15.15。
当教育网下的用户访问Portal服务器地址时，由于接口GE1/0/1没有配置智能DNS功能，因此最终用户得到的Portal服务器地址就是其原本教育网分配的公网地址1.1.15.15。当ISP1下的用户访问Portal服务器地址时，DNS服务器返回给ISP1用户的DNS响应消息到达FW的GE1/0/2接口时，FW会把响应消息中原始的教育网地址1.1.15.15替换成ISP1分配的公网地址2.2.15.15，ISP1下的用户收到DNS响应消息后，就会和2.2.15.15这个地址进行通信。当然，在FW上还需要配置一条NAT Server映射，将Portal服务器的私网地址10.1.10.20和2.2.15.15进行绑定，从而实现ISP1下的用户通过ISP1的地址2.2.15.15和Portal服务器进行通信。
表1-7 智能DNS配置规划
NAT
NAT Server
为保证各个ISP的用户能够访问内网服务器，需要在FW上部署NAT Server功能，将服务器的私网地址转换成公网地址。
表1-8 NAT Server配置规划
源NAT
为保证大量内网用户能够利用有限的公网IP地址访问外网，需要在FW上部署源NAT功能，将报文的私网IP地址转换成公网IP地址。
表1-9 源NAT配置规划
NAT ALG
FW配置NAT功能后，如果需要转发多通道协议报文（例如FTP协议），则必须开启该协议对应的NAT ALG功能，保证多通道协议报文可以顺利的进行地址转换。本案例中以FTP、QQ和RTSP协议为例，开启这些协议对应的NAT ALG功能。
攻击防范
攻击防范功能可以检测出多种类型的网络攻击，包括DDoS攻击和单包攻击，保护内部网络免受恶意攻击。
表1-10 攻击防范配置规划
审计策略
FW支持审计功能，通过审计策略定义需要审计的上网行为并进行记录，管理员后续可以对用户的上网行为进行审查和分析。
表1-11 审计策略配置规划
带宽管理
由于P2P流量非常耗费带宽资源，所以学校希望限制ISP1各链路上的P2P流量带宽，并针对单个IP的P2P流量带宽进行限制。带宽管理功能可以针对特定类型的流量进行整体限流或者限制每IP/每用户的流量。
表1-12 带宽管理配置规划
日志服务器设备
日志服务器可以进行日志的收集、查询和报表呈现。FW和日志服务器进行配套使用后，可以在日志服务器上查看FW输出的会话日志，其中也包含NAT转换前后的会话日志，通过这些日志即可查看到NAT转换的地址信息；也可以在日志服务器上查看FW输出的IPS日志和攻击防范日志，通过这些日志即可查询出网络中的攻击行为和入侵行为。
表1-13 对接网管设备配置规划
注意事项
1、 ISP地址集中的IP地址是否齐全直接影响智能选路、智能DNS功能的实施效果，请定期从安全中心平台（isecurity.huawei.com）更新ISP地址库。
2、多出口场景下，策略路由智能选路不能和IP欺骗攻击防范功能或URPF（Unicast Reverse Path Forwarding，单播逆向路径转发）功能一起使用。如果开启IP欺骗攻击防范功能或URPF功能，可能导致FW丢弃报文。
3、智能DNS功能需要License授权，并通过动态加载功能加载相应组件包后方可使用。
4、服务器负载均衡功能的虚拟服务器的IP地址不能和下列IP地址相同：
（1）NAT Server的公网IP地址（global IP）
（2）NAT地址池中的IP地址
（3）网关的IP地址
（4）FW的接口IP地址
5、服务器负载均衡功能的实服务器的IP地址不能和下列IP地址相同：
（1）虚拟服务器的IP地址
（2）NAT Server的公网IP（global IP）
（3）NAT Server的内网服务器IP地址（inside IP）
6、配置服务器负载均衡功能后，在配置安全策略和路由功能时，需针对实服务器的IP地址进行配置，而不是虚拟服务器的IP地址。
7、配置NAT地址池和NAT Server后，需要针对地址池中的地址和NAT Server的公网地址配置黑洞路由，防止产生路由环路。
8、只有审计管理员才能配置审计功能和查看审计日志。
9、只有支持安装硬盘且硬盘在位的设备才能在Web界面上查看和导出审计日志。
10、在报文来回路径不一致的组网环境中，审计日志记录的内容可能不完整。
配置步骤
1、配置接口和安全区域，并为参与选路的出接口配置网关地址、带宽和过载保护阈值。

15、配置系统日志和NAT溯源功能，在网管系统eSight上查看日志。
#配置向日志主机（10.1.10.30）发送系统日志（本案例发送IPS日志和攻击防范日志）。
[FW] info-center enable
[FW] engine log ips enable
[FW] info-center source IPS channel loghost log level emergencies
[FW] info-center source ANTIATTACK channel loghost
[FW] info-center loghost 10.1.10.30
#配置会话日志功能。
[FW] security-policy
[FW-policy-security] rule name trust_edu_zone
[FW-policy-security-rule-trust_edu_zone] source-zone trust
[FW-policy-security-rule-trust_edu_zone] destination-zone edu_zone
[FW-policy-security-rule-trust_edu_zone] action permit
[FW-policy-security-rule-trust_edu_zone] session logging
[FW-policy-security-rule-trust_edu_zone] quit
[FW-policy-security] rule name trust_isp1_zone
[FW-policy-security-rule-trust_isp1_zone] source-zone trust
[FW-policy-security-rule-trust_isp1_zone] destination-zone isp1_zone1 isp1_zone2 isp1_zone3
[FW-policy-security-rule-trust_isp1_zone] action permit
[FW-policy-security-rule-trust_isp1_zone] session logging
[FW-policy-security-rule-trust_isp1_zone] quit
[FW-policy-security] rule name trust_isp2_zone
[FW-policy-security-rule-trust_isp2_zone] source-zone trust
[FW-policy-security-rule-trust_isp2_zone] destination-zone isp2_zone1 isp2_zone2
[FW-policy-security-rule-trust_isp2_zone] action permit
[FW-policy-security-rule-trust_isp2_zone] session logging
[FW-policy-security-rule-trust_isp2_zone] quit
[FW-policy-security] quit
16、配置SNMP功能，日志服务器上的SNMP参数需要与FW上保持一致。
[FW] snmp-agent sys-info version v3
[FW] snmp-agent group v3 inside_snmp privacy
[FW] snmp-agent usm-user v3 snmp_user group inside_snmp
[FW] snmp-agent usm-user v3 snmp_user authentication-mode sha cipher [email protected]
[FW] snmp-agent usm-user v3 user-name privacy-mode aes256 cipher [email protected]
日志服务器配置完成后，在日志服务器上选择“ 日志分析 > 会话分析 > IPv4会话日志”，可以查看会话日志。
结果验证
1、校内用户访问外网时，目的地址属于教育网的流量从接口GE1/0/1转发，目的地址属于ISP1的流量从接口GE1/0/2转发，目的地址属于ISP2的流量从接口GE1/0/3转发。
2、访问其他高校服务器的流量和图书馆内用户的上网流量从GE1/0/1转发。
3、查看IPS特征库的配置信息和升级信息。
#使用display update configuration命令查看当前升级特征库的配置信息。
