What senior security engineer skills would you recommend for someone trying to advance their career?

Kermit Burley M.Ed.

Program Coordinator of Information Technology and Cybersecurity Analytics and Operations, Pennsylvania State University - Lehigh Valley

In my fields of Cyber and Information Technology we truly need the abilities to be always learning and always preparing for the next great breakthrough or the next big threat. So, adaptability and a willingness to always be learning are essential for success. Of course, our greatest challenge now and certainly in the next 3-5 years will be AI. (Artificial Intelligence) It is already upon us and has the potential to revolutionize our field and the entire landscape of what we do. The ability to stay ahead of that very steep hill will require constant innovation and an ability to accurately anticipate what is coming just around the corner. What I also see is an increased need for "people" skills, the ability to lead a team of people to achieve goals and budgetary requirements. All too often graduates in Cyber and IT are stereotyped as not having any people skills at all and preferring to work alone. This stereotype must end and those graduates who possess people skills will be in great demand not only in the next 3-5 years, but for decades to come.

What soft skills should all senior security engineers possess?

Dr. Steven MacMartin

Director, Associate Professor, Medaille College

Absolutely - writing and oral presentation. A secondary skill that is helpful is academic research skills. But definitely writing skills.
