Learn what data visualization tools are available to help with network security visualization. Jungwoo shows well-known visualization tools and how they can be useful in network security visualization.
- [Instructor] Visualization is a critical piece in network security since it bridges the cognition gap between the diversity and complexity of network data and actionable intelligence for network engineers. Network security visualization comes in primarily three different flavors. One of the most common is a dashboard built into a network security product such as vulnerability management system or SIM. IBM QRadar is a good example. The second approach is using a programming language to implement your own visualization for a specific network security application.
Python is a good example for this choice. The nice thing about Python is its powerful libraries readily available for numerous programming tasks. Visualization is not an exception. There are many Python visualization libraries available free of charge including matplotlib, ggplot, et cetera. The third choice is to use is stand alone data visualization tool. Tools like Tableau offer more flexibilities and varieties in ways to visualize the same network security data.
In fact, sky is the limit when it comes to how you represent your network security data especially when you have dedicated visualization tools at your fingertips. Despite the abundance of these visualization options, what really matters is your skills and creativity as a visualization specialist. Regardless of the amount of the data you have and the number of tools you have access to, effective visualization doesn't happen without human experts who know what they're doing.
