How can you configure a network to allow only a single node to access the network from a particular port?
Since your job will be to project the organization's most valued asset, its data, interviewers will ask you many questions about how you do this. Once they select and hire a candidate, they entrust them to keep the organization's proprietary information and users secure. You will be asked many questions like this during the interview until the interviewer is convinced you can do this job effectively.
Knowing how to configure a network so that only a single node can access it from a specific port is a fundamental skill information security managers need to possess. If a user's system is hacked, it can be piggybacked on to gain access to the network, and bad things will happen. Your answer should demonstrate your understanding of this important issue and the methodologies you use to prevent it from happening. Describe a process you can use that, based on your research, is already being used by the organization.
"I use sicky ports to prevent multiple systems from accessing the network from a single port. This allows me to configure the network so that each port on a switch only permits authorized nodes to access the port by associating it to specific MAC addresses. Other computers attempting to access the port will shut it down."
