防御保护第一次实验：安全策略配置

一、实验拓扑

在这里插入图片描述

二、实验要求

在这里插入图片描述

三、需求分析

1.创建两个vlan
2.在ENSP中配置基于时间的ACL实现对于办公区PC访问OA Server的时间限制（工作日早8到晚6）。
3.通过配置基于MAC地址的ACL来实现对于生产区PC访问Web Server的限制（除PC3外不能访问）。
4.在三层交换机上配置不同VLAN的接口IP地址，并启用路由功能，以确保不同VLAN之间能够进行通信。同时，要为OA Server和Web Server配置相应的IP地址和网关，使它们能够在网络中被正确识别和访问。

四、实验配置

1.配置vlan与access、truck接口

[sw1]vlan 2
[sw1]vlan 3
[sw1]interface GigabitEthernet 0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[sw1-GigabitEthernet0/0/1]interface GigabitEthernet 0/0/2
[sw1-GigabitEthernet0/0/2]port link-type access
[sw1-GigabitEthernet0/0/2]port default vlan 2
[sw1-GigabitEthernet0/0/2]interface GigabitEthernet 0/0/3
[sw1-GigabitEthernet0/0/3]port link-type access
[sw1-GigabitEthernet0/0/3]port default vlan 3
[sw1-GigabitEthernet0/0/3]interface GigabitEthernet 0/0/4
[sw1-GigabitEthernet0/0/4]port link-type access
[sw1-GigabitEthernet0/0/4]port default vlan 3

2.web

[FW]interface GigabitEthernet 1/0/1.1
[FW-GigabitEthernet1/0/1.1]service-manage ping permit
[FW-GigabitEthernet1/0/1.1]interface GigabitEthernet 1/0/1.2
[FW-GigabitEthernet1/0/1.2]service-manage ping permit

3.安全策略

办公区pc在工作日时间可以正常访问oa区其他时间不允许

办公区pc可以任意时刻访问web区

生产区pc可以任意时刻访问oa，但是不能访问web

使用ensp完成的方法
