fwknop

fwknop - 单包授权 Single Packet Authorization 简介 fwknop 实现了一种称为单包授权 SPA 的授权方案，用于强大的服务隐藏。SPA 只要求一个数据包，该数据包经过加密、不可重放，并通过 HMAC 进行身份验证，以便向隐藏在默认丢弃过滤规则的防火墙后面的服务传达所需的访问权限。SPA 的主要应用是使用防火墙丢弃所有尝试连接到 SSH 等服务的行为，从而使利用漏洞（包括 0-day 和未打补丁的代码）更加困难。由于没有开放端口，任何通过 SPA 隐藏的服务自然无法被 Nmap 扫描到。fwknop 项目支持四种不同的防火墙：Linux 上的...

zmap

ZMap：互联网扫描器 ZMap 是一个快速的无状态单包网络扫描器，专为互联网范围内的网络普查而设计。在配备千兆以太网连接的典型台式计算机上，ZMap 能够在45分钟内扫描整个公共 IPv4 地址空间的单个端口。例如，向端口25上的每个 IPv4 地址发送 TCP SYN 数据包以查找潜在的 SMTP 服务器。借助10GigE连接以及 netmap 或 PFRING，ZMap 可以在5分钟内扫描整个 IPv4 地址空间。 ZMap 可在 GNU/Linux、Mac OS 和 BSD 上运行。ZMap 已完全实现了用于 TCP SYN 扫描、ICMP、DNS 查询、UPnP、BACNET...
