Network outages, hacking, computer viruses, and similar incidents affect our lives in ways that range from inconvenient to life-threatening. As the number of mobile users, digital applications, and data networks increase, so do the opportunities for exploitation.
Cyber Security Overview
Cyber security, also referred to as information technology security, focuses on protecting computers, networks, programs, and data from unintended or unauthorized access, change, or destruction.
Government agencies, the military, corporations, financial institutions, hospitals, and other groups collect, process, and store a great deal of confidential information on computers and transmit that data across networks to other computers. With the growing volume and sophistication of cyber attacks, ongoing attention is required to protect sensitive business and personal information, as well as safeguard national security.
Emma Garrison-Alexander, vice dean of cybersecurity and information assurance in the Graduate School, talks about her experience in the industry and how it guides her passion for teaching.
Not only am I in a very hot field, I'm also in a good company where I feel secure, and I like what I'm doing a lot. And I feel like I'm [adding] value not just to myself but to the country and to the government…. I'm heading in the right direction for my career.

When I mentioned UMUC, everybody’s eyes lit up in the room because they knew that the [cyber security] program had a good reputation in the industry.
Cate Reich, MS
The curriculum has a flexibility about it that I haven’t seen from other academic institutions. UMUC, I think, has cracked the code in terms of allowing it to be very agile and very much focused on the changing dimensions of cyber security.
President and CEO, Cyber Security Strategies
UMUC deserves the highest praise for recognizing and responding to the critical workforce need for trained professionals in the field…. It is an exciting time for cyber security, for the state of Maryland, and for UMUC.
Former Governor, State of Maryland
