无论是2台PC机相连的办事处,还是10万个节点的网络,每一项业务都需要防火墙的保护,因为任何挂接在Internet上的计算机都是易于浏览和可攻击的。只要把探测器安置在您的调制解调器的电缆上,就可以了解探测器的扫描过程会占用多长时间。 当然,重要的设备常常是昂贵的,无论是软件防火墙还是硬件防火墙无一例外。除了已知的有效维护和安装费用概算外,企业还必须承担培训费用或雇佣有防火墙经验的人。由于网络的安全范围的扩展已超过了防火墙的范围,在决定防火墙的安全配置之前,企业必须制定安全策略、分析和定义网络用法及安全响应过程、检查业务处理进程。 在评估了这一需求之后,一些公司决定建立他们自己的防火墙,而另一些公司则要外包管理服务。但是,即使一个企业使用了现有的最好的解决方案,并且雇佣了有丰富安全经验的人,也不能保证其网络不会中断。 下面我们将详细讨论相对于内部服务而言的外包服务的正反面理由。
Whether it’s two PCs connected offices or a 100,000-node network, every business needs firewall protection because any computer attached to the Internet is easy to navigate and attack. Just place the detector on your modem’s cable to see how long it takes for the detector’s scanning process. Of course, important equipment is often expensive, no matter whether it is a software firewall or a hardware firewall. In addition to the known cost estimates for effective maintenance and installation costs, businesses must also afford training costs or hire someone with a firewall experience. Because the security of the network extends beyond the scope of the firewall, organizations must make security policies, analyze and define network usage and security response processes, and examine the business processes before deciding on the security configuration of the firewall. After assessing this demand, some companies decided to set up their own firewalls while others outsourced management services. However, even if a company uses the best available solution and hires people with rich security experience, there is no guarantee that its network will not be interrupted. Below we discuss in detail the pros and cons of outsourcing services relative to internal services.
