Learn how to select your network visualization targets. Jungwoo provides examples such as host monitoring, interactions between internal and external hosts, host activities, and attack patterns.
- [Instructor] Once you have gathered enough data,…deciding what to visualize is the natural next step.…Fortunately, in the context of network security,…there are some obvious targets for visualization.…The first area of visualization is host monitoring.…The goal here is to present a big picture view of how…healthy your own network is by showing the status…of the individual hosts that make it up.…This view can entail details such as CPU…or memory consumption and suspicious or unusual activities…on the internal servers and clients.…
Another visualization target is the interactions…between internal and external hosts.…Compared to the internal host monitoring,…the complexity of this kind of visualization increases…an order of magnitude, due to the additional number…of external hosts, whose interactions with their…internal counterparts are also tracked in this scenario.…We can also drill down to narrow the scope…of our visualization much further and focus on a specific…aspect of host activities.…
For example, you can pick a host and monitor it's port…
