about more information on ping sweeps and port scans‚ I am going to provide you with some information to help you with any confusing that you may have. Port scans and ping sweeps are networking tools that admins use to perform normal and common functions such as‚ checking server to see if it is running correct or to determine with services are open so they can receive important updates. Hackers use the same function which can provide a hacker with information. Port scans‚ like I stated earlier‚ are

You reviewed a sample collection of data using NetWitness Investigator‚ connected to a remote Windows machine‚ and explored two file transfer applications‚ FileZilla and Tftpd64. You used PuTTY to connect to a Linux machine and ran several Cisco commands to display statistics for the network interfaces. Finally‚ you used Zenmap to perform a scan of the network and created a network topology chart. Lab Assessment
