Hackers usually perform an initial reconnaissance and probing scan to identify IP hosts‚ open ports‚ and services enabled on servers and workstations.

This is gained by searching the particular target online via Google search to obtain any information regarding the target. Thirdly‚ by using port scanning. We can download the tools and find the ports used by the target. Lastly‚ by using network mapping. Network mapping is the study of the physical connectivity of networks and often attempts to determine the servers and operating systems run on networks. OBJECTIVES
