1.僵尸网络 Botnet 是指采用一种或多种传播手段,将大量主机感染bot程序(僵尸程序)病毒,从而在控制者和被感染主机之间所形成的一个可一对多控制的网络. 2.第一个是 端口攻击 ,通过扫描端口的漏洞来进行攻击。第二个是 拒绝服务攻击 ,通过发送大量的信息来使网站瘫痪第三个是提权攻击,通过一个没有权限或者是权限很低的user用户做一些动作,绕过一些验证或者是直接通过一些系统或者网站的漏洞直接获取root(就是最高的权限)的权限,然后登陆进行一些非法的操作第四个是远程用户 攻击,一般是没有做好 远程控制 的用户 密码安全 工作所导致的漏洞,攻击者可以通过远程登陆计算机,然后用电脑的账号和弱口令来进入计算机进行操作,权限有的高有的低,这要看该漏洞电脑所开放的用户的管理权限的大小,像3389端口的远程攻击等都属于这一种。
3.恶意软件突破电脑信息系统防火墙,需要分析防火墙代码,在成功植入后需要考虑是否能够长期控制该网络,如果电脑信息安全系统识别该软件,将会建立针对该软件的防火墙,该软件此后将无法再植入,该软件需要极长的时间来制作,分析,而电脑防火墙软件会很快清理该软件. 1.Botnet refers to that uses one or more means of transmissions to infect a large number of hosts with a bot (zombie) virus, forming a one-to-many control network between the controller and the infected host. 2.The first is a port attack by scanning the loopholes in the port. The second is a denial of service of attack by sending a large amount of information. The third is a extracting attack with a user who has no privileges or very low permissions to do some actions, bypassing some certification or directly through some system or website’s loopholes to directly obtain root(the highest authority) ,and then log in and do some illegal operations. The forth is the attacks of the remote users. Generally, it is a loophole caused by the user’s password security that is not long-range controlled. The attacker can remotely log into the computers and enter the computer to operate with a computer’s account and weak password. The permissions are high and low, which depends on the size of administrative permissions of the open users of computers such as 3389-port remote attacks, belong to this category.
3. Malware breaks through the firewall of the computer information system to analyze the firewall code. After successfully implanted, it needs to consider whether it can control the network for a long time. If the the computer information system identifies the software , a firewall for the software will be established. The software will no longer be implanted, because it takes a vary long time to make and analyze. Therefore, the computer firewall software will quickly clean up the software.
