下面是规划与配置
1.vlan方面:推荐一个vlan下的所有主机为一个子网网段
连接电脑和http客户端的接口配置为access接口
交换机与交换机或路由器连接的接口配置为trunk接口---也可以配置为access接口但是为了扩展性,trunk接口更佳,允许vlan10到vlan100通过
对汇聚层交换配置对应的vlanif的ip地址
两个汇聚层交换机间配置eth-trunk,模式采用静态lacp

9.端口镜像/防火墙方面:在核心层路由器连接防火墙侧配置端口镜像,使其通过流量同时复制到防火墙,用于入侵检测或者攻击分析
路由器1:
sys
observe-port interface GigabitEthernet 5/0/2
int g5/0/3
mirror to observe-port both
int g0/0/1
mirror to observe-port both
int g0/0/2
mirror to observe-port both
int g0/0/0
mirror to observe-port both
int g5/0/0
mirror to observe-port both
int g5/0/1
mirror to observe-port both
路由器2:
sys
observe-port interface GigabitEthernet 2/0/3
int g0/0/0
mirror to observe-port both
int g0/0/1
mirror to observe-port both
int g0/0/2
mirror to observe-port both
int g2/0/0
mirror to observe-port both
int g2/0/2
mirror to observe-port both
int g2/0/1
mirror to observe-port both
10.配置kali虚拟机到目标网络
配置VMware中的虚拟网卡(此配置为172.22.30.x网段),并将其连接到交换机上(注意交换机要配置端口类型为access;并确保无ip地址冲突—真机的ip地址; kali虚拟机从交换机的dhcp服务器上获取ip地址)
kali注意要先nat联网下载Dsniff套装工具集,之后再连接到ensp虚拟环境(切记不要在nat模式下使用macof)
macof的攻击指令 sudo macof
交换机2:(实际是在所有上下行接口配置,此处演示需要只在一个接口配置)
sys
int g0/0/5
port-security enable
port-security protect-action shutdown
port-security max-mac-num 50
port-security aging-time 1000
arp anti-attack entry-check fixed-all enable
arp gratuitous-arp send enable
arp gratuitous-arp send interval 1
(启用ip报文转发模式:echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward)
arp欺骗的指令:sudo arpspoof -i eth0 -t 172.22.30.199 172.22.30.254
arp –d:清理arp表
arp –a 查看arp表
第一条配置arp固化,实验中没法显示(将本来接入的正常主机替换为攻击的kali机再发送arp欺骗时,可能可以显示效果)
第二第三条,配置免费arp并设置时间间隔为0.5s,只能在一定程度上抵抗已经接入的“可信”主机
还可以配置dhcp snooping,并在其基础上配置动态arp检测,以在新主机接入时就防范于未然
还可以直接在主机上指定静态arp来预防
11.端口安全和密钥方面:vrrp中使用了md5认证,交换机2配置了端口安全用于限制mac地址最大学习数量,交换机2.5.6配置了免费arp和arp固话用于预防arp欺骗,telnet远程认证配置了aaa认证,nat配置了对应的acl
12.主机侧的http
学习到的:
1~~~导入已有的包需要设置tomcat环境,配置项目结构
2~~~leaflet的access_token已经过期,需要自己去Account | Mapbox注册账号并替换
3~~~leaflet的地图库似乎更新了,需要更换参数和导入方式
注意:要开启mysql服务
ensp虚拟环境的任意http客户端通过该网址获取内容:http://223.104.244.33:8888/Idea_war_exploded/index.html (主机记得关闭防火墙,否则ping不通)
13.telnet配置交换机和路由器
路由器1、2和交换机5-8:
sys
aaa
local-user campaus privilege level 15
local-user campaus password cipher campaus
quit
user-interface vty 0 4
authentication-mode aaa
quit
ctrl+]退出telnet界面
13.ftp:在外网服务器上直接开启ftp服务即可
14.dns:
交换机5,6:
sys
ip pool forvlan10
dns-list 223.104.244.2
ip pool forvlan20
dns-list 223.104.244.2
ip pool forvlan30
dns-list 223.104.244.2
交换机7,8:
sys
ip pool forvlan40
dns-list 223.104.244.2
ip pool forvlan50
dns-list 223.104.244.2
ip pool forvlan60
dns-list 223.104.244.2
15.m0n0wall防火墙:于172.22.70.x网段处配置了m0n0wall防火墙,可用于如流量控制,流量监控的作用
16.wireshark 统计---捕获文件属性,协议分级
snmp-agent
snmp-agent community read campaus
snmp-agent community read campaus1
snmp-agent sys-info version all
snmp-agent target-host trap-hostname zjut address 223.104.244.33 udp-port 162 trap-paramsname zjut
snmp-agent trap enable
开启步骤:主机联网并关闭防火墙(kali虚拟机端的云可能需要手动undo shutdown下)--->开启kali虚拟机和windows虚拟机(windows 7为snmp用)
有待改进的地方:
内网ospf可以划分多个区域,将核心层至出口路由器组成区域0,核心层和汇聚层间的路由器/三层交换机组成区域x
snmp-网管系统;dhcp安全àipsg(防止用户私自修改ip或防止非法用户使用静态ip地址私自接入)和dai(新开个端口接入设备模拟arp和dhcp攻击),mac地址防漂移
