Understanding Network Visibility Use Cases!
Network visibility is fast becoming a key component of network and security planning. This is because network visibility is more than just network monitoring. It is about understanding the network—how is it actually performing, are there any current problems, where do future pain points lie, and how do I optimize my resources? IT’s fundamental challenge is to ensure that the infrastructure beneath their applications is reliable, fast, and secure.
As we all know, network blind spots get in the way. Common sources of blind spots include: Silo IT organizations, SPAN port overloading, rogue IT, SSL encrypted data, data overload of monitoring equipment, and network and equipment complexity. These blind spots directly correlate to network problems and outages, increased network security risk, and potential regulatory compliance issues.
Encrypted data further exacerbates the situation. According to a Bluecoat infographic, half of all network security attacks in 2017 will use encrypted traffic to bypass controls. In addition, internal and external SLA’s and customer quality of experience have become increasingly important for IT. These requirements are forcing IT to gain an even better insight and understanding of the network to maximize performance. What no IT team wants to find out is that all of their assumptions and architecture designs are based on incorrect or missing data. When this happens, it results in higher solution costs, confusion, rework, customer dissatisfaction, performance problems, and unplanned outages.
