课程名称：网络安全入门套件 (CSSK) - 2023 课程概述： 本课程旨在介绍道德黑客的相关知识。道德黑客是指探索突破防御和利用计算机系统或网络弱点的方法的安全黑客。课程内容包括： 1. **摸底侦查（Foot Printing）**：这是一种侦察过程，用于收集关于目标计算机系统或网络的可能信息。 2. **端口扫描（Port Scanning）**：端口是数据进出系统的“门”。计算机使用端口号来确定将消息传递给哪个进程或应用程序。网络地址类似于街道地址，而端口号则类似于套房或房间号。 3. **网络基础（Network Fundamentals）**：计算机网络是一个数字电信网络，允许节点共享资源。互联网协议地址是分配给连接到计算机网络的每个设备的数字标签，用于使用互联网协议进行通信。网关是计算机网络中的一个节点（路由器），是数据在往返于其他网络时的关键停靠点。路由器是一种网络设备，用于在计算机网络之间转发数据包，负责互联网的流量引导功能。网络交换机则是一种计算机网络设备，通过包交换将设备连接在一起，用以接收、处理和转发数据到目标设备。 本课程为学习网络安全打下基础，适合初学者。
Introduction Ethical Hacking:-A security hacker is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network.Foot Printing:-Foot printing is a part of reconnaissance process which is used for gathering possible information about a target computer system or network.Port Scanning:-Port are the doors from which data enters & leaves the system.Computers use port numbers to determine to which process or application a message should be delivered. As network addresses are like street address, port numbers are like suite or room numbers.Network Fundamentals:-A computer network, is a digital telecommunications network which allows nodes to share resources.An Internet Protocol address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.A gateway is a node (router) in a computer network, a key stopping point for data on its way to or from other networks. Thanks to gateways, we are able to communicate and send data back and forth.A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet.A network switch is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device
