The human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us aajust to the outside world. Without our nerves and our brain, which is a system of nerves, we couldn’t know what’s happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain. But there is a way to handle pain. Look at the Indian fakir (苦行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain. The big thing in withstanding pain is our attitude toward it. If the dentist says, “This will hurts a little,” it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensafion, and sensations are the stuff of life. [共5题]

    阅读以下说明,回答问题1至问题6,将解答填入对应的解答栏内。

    [说明]

    某企业的网络拓扑结构如图4-1所示。

    防火墙使用安全区域的概念来表示与其相连接的网络。图4-1中inside、outside和dmz区域对应Trust区域、Untmst区域和dmz区域,不同区域代表了不同的可信度,默认的可信度由高到低的顺序为(1)。 (1)备选答案: A.inside、outside、dmz

    B.inside、dmz、outside

    C.outside、dmz、inside

    D.outside、inside、dmz


    正确答案:B
    B 解析:考查防火墙安全区域的概念,防火墙一般分为Trust区域、Untmst区域和DMZ区域三个安全区域,Trust区域是指位于防火墙之内的可信网络,是防火墙要保护的目标;Untmst区域是位于防火墙之外的公共开放网络,一般指因特网;DMZ也称周边网络,安全敏感度和保护强度较低,一般用来放置提供公共网络服务的设备。一般把可信度高的主机放置于Trust区域,把因特网隔离于Untrust区域,DMZ区域用于放置可信度介于内部主机和因特网的各类服务器。所以从图4-1可以看出,可信度的顺序应该是inside>dmz>outside,答案应该为B。

  • 第4题:

    为了保障内部网络安全,某公司在Internet的连接处安装了PIX防火墙,其网络结构如图12-6所示。

    完成下列命令行,对网络接口进行地址初始化配置:

    Firewall(config)ip address ins.ide ______ ______

    Firewall(config)ip address outside ______ ______

    阅读以下防火墙配置命令,为命令选择正确的解释。

    Firewall(config)global(outside)1 61.144.51.46 ______

    Firewall(config)nat(inside)1 0.0.0.0 0.0.0.0

    Firewall(config)static(inside,outside) 192.168.0.1 61.144.51.42


    正确答案:192.168.0.1 255.255.255.0 61.144.51.42 255.255.255.248 A
    192.168.0.1 255.255.255.0 61.144.51.42 255.255.255.248 A 解析:ip address inside和ip address outside命令用来完成内网和外网的配置。根据图中的ip address inside192.168.0.1 255.255.255.0表示配置掩码为255.255.255.0的IP地址,192.168.0.1为内网地址。
    ip address outside61.144.51.42.255.255.255.248表示配置掩码为255.255.255.248的IP地址,61.144.51.42为外网地址。
    global指定公网地址范围、定义地址池,表示当内网的地址访问外网时,地址统一映射为ip_address-ip_address地址段的地址。
    语法:global(if_name)nat_id ip_address-ip_address[netmakglobal_mask]
    (if_name):表示外网接口名称,一般为outside。
    nat_id:建立的地址池标识(nat要引用)
    ip_address-ip_address:表示一段IP地址范围。
    [netmakglobal_mask]:表示全局IP地址的网络掩码。
