说起网络安全,大家首先想到的应该是当我们在Interneth上冲浪的时候,预防其他人连接到计算机中进行破坏活动。所以很多人都采用了ZoneAlarm、天网之类的防火墙保护系统的安全。但是随着OA(办公自动化)进程的加快、单位的计算机构建成为一个小型局域网、这时如果出于工作需要共享某个文件夹之后, 别人就有可能侵入你的计算机盗取重要文件。即使你没有共享任何文件夹,只要通过木马程序的帮助,别人也可以获取你计算机中的文件。可见除了对于Internet的攻击防护之外,局域网内部的安全防护也是也非常重要的。 目前的各类防火墙大多数都仅仅针对来自于Internet的攻击进行防护,而对于内部局域网无能为力了,那么如何才能有效地斩断来自局域网中的黑手呢?各位不妨和笔者一起来看看这个大家都很熟悉的Lockdown。
When it comes to cybersecurity, the first thing that comes to mind is to prevent others from connecting to computers for sabotage while we’re surfing on Interneth. So many people have adopted ZoneAlarm, Skynet-like firewall to protect the security system. However, with the acceleration of the OA (office automation) process, the unit’s computer is built into a small local area network. When a folder needs to be shared for work, others may invade your computer to steal important files. Even if you do not have any folders, you can get the files from your computer with the help of a Trojan. Visible in addition to the Internet attack protection, LAN internal security is also very important. Most of the current types of firewalls are only for the protection from attacks on the Internet, and for the internal LAN can not do anything, then how to effectively cut off the black from the LAN? You and the author may wish to have a look at this everyone Familiar with Lockdown.
