The IP should be on the same LAN. 192.168.10.1/24 is the Gateway IP address from the table.

Explanation
User activity reports were used to identify the security breach in the human resources department. User activity reports are records of the actions and events performed by users on a system or network, such as login/logout times, files accessed or modified, commands executed, or websites visited. User activity reports can help monitor and audit user behavior, detect and investigate security incidents, and enforce policies and compliance. User activity reports can be generated by various tools, such as log management software, security information and event management (SIEM) systems, or user and entity behavior analytics (UEBA) solutions.

To disable root login over SSH, the server administrator needs to edit the SSH configuration file located at
/etc/ssh/sshd_config. This file contains various settings for the SSH daemon that runs on the server and accepts incoming SSH connections. The administrator needs to find the line that says PermitRootLogin and change it to no or comment it out with a # symbol. Then, the administrator needs to restart the SSH service for the changes to take effect.References:https://www.howtogeek.com/828538/how-and-why-to-disable-root-login-over-ssh-on-linux/
