端口扫描。计算机开放的端口与其开放的服务相对应,渗透测试人员可以通过端口扫描大致了解目标打开了哪些服务,比如80端口与HTTP服务相对应、3306端口与MySQL数据库相对应、1433端口与MSSQL数据库相对应。分析了开放端口后,我们便可以大致了解目标网站所用到的数据库,并可以尝试进行数据库的爆破。另外,端口扫描对于后台查找和后期下载权限也很重要。还有什么是通用的端口扫描方式呢?(1)网上平台。许多平台提供了端口扫描功能,以及公共服务中默认的端口。这两步只是最常见的搜集手法,如果想要对网站或APP进行更详细的渗透测试服务的话可以到SINESAFE,鹰盾安全,绿盟,启明星辰这些安全公司来做全面的安全检测。
