PESC 105 – IP Networks & Cyber Security

As networks grow and interconnect with other networks including the internet, these networks are exposed to a greater number of security risks. Not only does the number of potential attackers grow along with the size of the network, but the tools available to these potential attackers keep increasing in terms of sophistication. In this module, learners will be introduced to network topology, cybersecurity and its components, and the various threats targeting the network security, surveillance, and physical security systems.
