We all know that our online identities need to be protected. We learn tips on how to come up with efficient passwords and how to set up password verification steps to ensure no one gets access to our online accounts, yet when it comes to securing our networks, we do little to ensure these are safe.

In it, she talked about how easy it is to hack into some water/wastewater facility network. MacKenziesaid that even a "high school geek" can play around with the network's programming and affect your home water quality.

Many argued that the lack of protection and separation had its advantages, but this also left the network vulnerable to malware attacks and other cybersecurity breaches.

Changes had to be made to secure the network and a team worked together to ensure the water/wastewater facility network was secured efficiently.
