"PKI was an important part of my role and responsibility. I had to ensure that digital certificates were managed properly so that users would be able to have access to approved sites locally and remotely. I made sure that all information on our website wasn't getting into the wrong hands. Without PKI, all our confidential information could be hacked easily using simple passwords. I made sure that we had a high level of security in place for authentication and access to important information to prevent such attacks from happening. I've been working within a Public Key Infrastructure for a while and have learned that data encryption is at the heart of authentication and password protection."

"In my current role, I had to look up the public key of a receiver and a sender to ensure that both keys matched before allowing access to our systems. In other words, I perform a higher level of authentication than just typing in a password to further ensure protection. Our corporate policy dictates that we need to follow a structured framework for hardware and software data encryption to ensure trust for all parties. I strongly believe that having PKI in place to optimize cyber security is essential for every serious website owner. I was also one of the team members who made a contribution to writing our encryption policy."

Public Key Infrastructure or PKI is an essential technique cyber security professionals use to protect the organization's information.
