全球网络资产大数据
收藏资源简介:
数据公开采集,主要方式 1. 主动探测: 通过向目标主机发送数据包,分析返回的响应数据包来获取目标主机的信息。 常用的网络协议包括ARP、ICMP、TCP等。 端口扫描方式包括SYN扫描、Connect扫描、UDP扫描等。 2. 被动探测: 利用网络嗅探工具获取目标网络的数据报文,分析报文数据来获取网络资产信息。 3. 基于搜索引擎的非侵入式探测: 利用专用的网络安全搜索引擎等获取网络资产信息。 4. 流量监控: 通过监控网络流量来自动获取资产和开启的服务信息。 5. 别名解析和DNS探测: 建立IP地址和路由器的映射关系,以及IP地址和域名之间的对应
Public data collection, with the primary methods listed below: 1. Active Probing: Send data packets to target hosts, analyze returned response packets to gather information about the target hosts. Commonly used network protocols include ARP, ICMP, TCP, etc. Port scanning methods include SYN scan, Connect scan, UDP scan, etc. 2. Passive Probing: Utilize network sniffing tools to capture data packets from the target network, and analyze the packet data to obtain network asset information. 3. Non-intrusive Probing Based on Search Engines: Acquire network asset information using dedicated cybersecurity search engines and similar tools. 4. Traffic Monitoring: Automatically obtain asset information and enabled service details by monitoring network traffic. 5. Alias Resolution and DNS Probing: Establish mapping relationships between IP addresses and routers, as well as correspondences between IP addresses and domain names.
