Network Threats & Defenses for Beginners

Network Threats and Defenses for Beginners introduces foundational cybersecurity concepts for learners who already have a basic understanding of networking. The course explains common attack categories, threat actor behavior, encryption, access control, authentication, segmentation, and defensive practices that help reduce security risk. Learners review common and often overlooked security weaknesses, including poor configuration, weak credentials, limited monitoring, and exposed systems. The course helps learners understand how attackers identify and exploit these gaps, and how organizations can use layered security controls to reduce the chance of successful attacks. By connecting networking knowledge with practical security awareness, this course helps beginners understand how cyberattacks happen, why defenses must be planned in layers, and how stronger security habits support safer network operations.

Keith Bogart

Course Instructor

Keith started his networking career as customer service representative at Cisco Systems in 1996. His desire to learn more soon led him to a position as a Cisco Technical Assistance Center (TAC) engineer on the “Dial-Access” team, and within six months he had obtained his Dial-ISP CCIE. He later became a network consulting engineer and obtained his CCNA certification while teaching the technologies to Cisco employees during his lunch breaks. Keith was the first instructor on Cisco’s TAC Training team, where he taught a wide range of internetworking topics and later developed and taught other courses such as routing protocols, LAN switching, MPLS, 802.1x, and CCNA. After almost 17 years with Cisco, Keith joined a small startup and focused on 802.11 Wi-Fi technologies, during which time he obtained his CWNA certification. He is now very happy to be working with as an instructor for Routing & Switching. Keith lives in Raleigh, North Carolina, with his wife, son, and daughter. When he is not teaching Bootcamps, Keith can be found at home with his family, reading, or working in the yard.
