安全策略

虚墙拥有和根墙相同的属性，因此SSH是支持的。

1.1  配置SSH服务器

#进入系统视图

<H3C>system-view

# 生成RSA密钥对，在提示“Y/N”的时候选择“Y”。

[H3C]public-key local create rsa

The local key pair already exists.

Confirm to replace it? [Y/N]:y

The range of public key modulus is (512 ~ 2048).

If the key modulus is greater than 512, it will take a few minutes.

Press CTRL+C to abort.

Input the modulus length [default = 1024]:

Generating Keys....

Create the key pair successfully.

# 生成DSA密钥对

[H3C]public-key local create dsa

The range of public key modulus is (512 ~ 2048).

If the key modulus is greater than 512, it will take a few minutes.

Press CTRL+C to abort.

Input the modulus length [default = 1024]:

Generating Keys.....

Create the key pair successfully.

# 开启SSH服务器功能

[H3C]ssh server enable

# 配置接口GigabitEthernet1/0/4的IP地址，客户端将通过该地址连接SSH服务器。

[H3C]interface GigabitEthernet1/0/4

[H3C-GigabitEthernet1/0/4]ip address 192.168.10.1 255.255.255.0

[H3C-GigabitEthernet1/0/4]quit

# 设置SSH客户端登录用户线的认证方式为AAA认证。

[H3C]line vty 0 63

[H3C-line-vty0-63]authentication-mode scheme

[H3C-line-vty0-63]quit

# 创建设备管理类本地用户为admin，密码为admin；并设置服务类型为SSH，用户角色为network-admin。

[H3C]local-user admin

[H3C-luser-manage-admin]service-type ssh

[H3C-luser-manage-admin]authorization-attribute user-role network-admin

[H3C-luser-manage-admin]password simple admin

[H3C-luser-manage-admin]quit

1.2  防火墙域间策略配置

# 把接口GigabitEthernet1/0/1加入trust区域

[H3C]security-zone name Trust

[H3C-security-zone-Trust]import interface GigabitEthernet1/0/1

[H3C-security-zone-Trust]quit

#创建对象策略pass。

[H3C]object-policy ip pass

[H3C-object-policy-ip-pass] rule 0 pass

[H3C-object-policy-ip-pass]quit

#创建Trust到Local域的域间策略调用pass策略。

[H3C]zone-pair security source Trust destination Local

[H3C-zone-pair-security-Trust-Local]object-policy apply ip pass

[H3C-zone-pair-security-Trust-Local]quit

#创建Local到Trust域的域间策略调用pass策略。

[H3C]zone-pair security source Local destination Trust

[H3C-zone-pair-security-Local-Trust]object-policy apply ip pass

[H3C-zone-pair-security-Local-Trust]quit

1.3  限制用户SSH登录设备

#只允许内网192.168.10.0/24网段用户登录设备

#配置ACL：

[H3C]acl basic 2999

[H3C-acl-ipv4-basic-2999]rule permit source 192.168.10.0 0.0.0.255

[H3C-acl-ipv4-basic-2999]quit

#在SSH服务中调用

[H3C]SSH server acl 2999

#测试无问题后，再保存配置

[H3C]save force
