I have been an IT Professional for 15 years, focusing on computer networking and telecommunications. Unprofessionally, I built my first computer in 6th grade to play Quake 2 and Mechwarrior 2. The first network I used was dial-up. My buddy and I would dial into each other's modems to play Quake 2 together.
I became interested in cybersecurity about 7 years ago when I worked for a bank. It fits my persona well because I have always been interested in personal/physical security. I participated in defensive-based pistol competitions and dabbled in MMA. I love cybersecurity and being safer in the virtual and physical world. It can be scary out there.
I have recently taken up the role of IT Security Administrator, and I am excited to share my experience with others.
Session
Discussions of network segmentation take place in many public forums like conferences and workshops relating to protecting network infrastructure. What needs to be improved is guidance on how to approach it and what steps to take to apply it. As important as the technical design, it is essential to understand the goals of network segmentation for business continuity. There are two perspectives on network segmentation. One is from the perspective of the network engineer, and one is from the perspective of the cybersecurity engineer. This presentation will highlight the different perspectives of network segmentation and share philosophies on approaching it. This presentation will also discuss segmenting network topologies with Access Control List and firewalls and the importance of designing a flexible IP schema.
