Learn about the essential steps involved in network security visualization. Jungwoo presents what is involved in the visualization steps such as deciding on requirements, thinking about the data necessary to satisfy the requirements, and preprocessing the data.
- [Instructor] To avoid an ineffective visualization…that causes misunderstanding and confusion it's crucial…to follow a step-by-step process to produce an…informative and useful interpretation of raw data.…The very first step is to decide on your requirements.…This is also referred to as the problem phase.…What story are you trying to tell…about your net of security?…Are you seeking to gain more insight on connection attempts…to a secure shell server from different clients…by their country of origin, or are you interested…in knowing the volume of incoming or…outgoing network traffic through your router?…The second step is to think about the data we need…to meet the requirements or to answer the questions…formulated during the problem definition phase.…
Do we have sufficient data?…Are firewall logs what we should look at?…Or should we be looking at something else?…In our secure shell server example, it turns out that…we need the firewall logs as well…as secure server log files.…The data items you need in the firewall logs…
