根据调查显示，网络安全的就业缺口达700000个，刚步入这个行业的话，薪资大约在10左右。

网络安全的行业情况：

信息安全需求的提高

随着网民身份盗用、交易诈骗、薪资滥用、网络钓鱼等安全事件频繁发生，政府、企业、个人对信息安全的关注度日益增强，政府部门、重点行业在信息安全产品和服务的投入上也不断增加，使得社会对信息安全的需求持续提升。

国家政策的支持

国家有关部门相继出台了包括《网络安全法》在内的一系列法律法规和鼓励行业发展的产业政策，信息安全工作提高到国家战略高度。国家对信息安全产业的重视度也日益提高，因为政策的大力支持使得信息安全的发展得到了政策保障。

信息安全标准化工作的推进

国家为信息安全行业制定了一系列国家标准，规范了行业的发展，为信息安全产品的选用和研发提供了标准和依据，使得安全硬件厂商、安全服务商发展方向更明确。

信息技术不断发展革新

云计算、大数据、移动以及社交网络的快速发展给信息安全行业带来了巨大的变化，基础框架的变化于要求信息安全建设能够适应新的IT基础框架，从而满足新的安全需求，这同时为信息安全带来了新的发展空间，是的行业需要不断注入新生力人才，确保发展。

IPv6与IPv4的区别主要有以下几点：
1IPv6的地址空间更大。IPv4中规定IP地址长度为32,即有2^32-1个地址；而IPv6中IP地址的长度为128,即有2^128-1个地址。夸张点说就是，如果IPV6被广泛应用以后，全世界的每一粒沙子都会有相对应的一个IP地址。
2IPv6的路由表更小。IPv6的地址分配一开始就遵循聚类(Aggregation)的原则,这使得路由器能在路由表中用一条记录(Entry)表示一片子网,大大减小了路由器中路由表的长度,提高了路由器转发数据包的速度。
3IPv6的组播支持以及对流的支持增强。这使得网络上的多媒体应用有了长足发展的机会，为服务质量控制提供了良好的网络平台。
4IPv6加入了对自动配置的支持。这是对DHCP协议的改进和扩展，使得网络(尤其是局域网)的管理更加方便和快捷。
5IPv6具有更高的安全性。在使用IPv6网络中，用户可以对网络层的数据进行加密并对IP报文进行校验，这极大地增强了网络安全。
