Since you are interviewing for a position in which you will make recommendations to customers about protecting their company's network, I'm curious about what you do to protect your own network at home.

This is a 'trick' question which many applicants won't expect. You need to be prepared for this and should answer it honestly.

If you do not protect your own home as you would a client's network, then suggest to the interviewer the main reason being is that you don't work from home.

"That's a great question and one I've never been asked before. I take my family's security as serious as I do that of the companies I work with. My home network has all the same security measures I recommend to my customers at work. These include a strong firewall, user authentication, access control, and frequent audits. I also upgrade my network hardware, such as routers and NICs periodically as new security features are released."
