Intermapper flows1/1/2024 Anyone working in a heavily proxied enterprise will appreciate Increasingly, content is becoming more significant. IP addresses are an important element of network traffic but, Entire methods for meeting privacy concerns are needed.Ĭhallenge 6: Mixing and matching record types. That approach is too crude to handle modern protocols, especially when a large percentage of traffic is carried Lawful intercept tools have tried to honor these restrictions by applying filters to include or exclude certain traffic. Recognize that analysts might have to limit their activities in order to meet privacy or other regulations. Too many network tools assume the user is fully privileged. Still, analysts should haveĪ way to annotate network information for their benefit and the benefit of their teams.Ĭhallenge 5: Privacy. Depending on the data set and theĬlassification involved, tagging individual items in a packet or flow record can be difficult. Knowledge? Consider the "simple" problem of applying tags to network flows. As techniques and tools derive information from network data, it's often the analyst's responsibility to derive knowledge from the information. Severe limitations when working with thousands or millions of nodes.Ĭhallenge 4: Knowledge management. Tools which comfortably depict dozens or hundreds of nodes face Some tools to digest and render network data. In truly large networks, analysts are likely to begin reaching the limits of Trying to meet the two previous challenges is likely to be possible when the Useful to network administrators and defenders.Ĭhallenge 3: Visualization at scale. Doing this in an automated way would prove extremely To visualize the network based on observed traffic patterns. By placing instruments in enough locations, it should be possible If the network baseline challenge is related to traffic passing a single monitoring point, this involves multiple locations. Regardless, there is no single accepted taxonomy for creating a network traffic baseline.Ĭhallenge 2: Topology, locating the problem. More advanced approaches try to classify traffic according to flows or even content. Just what is this supposed to mean? Simplistic approaches concentrate on bandwidth utilization over time, typically focusing on spikes and troughs. Frequently network and security practitioners hear that the start of any network-Ĭentric project is to baseline the network. Here are the top seven networking traffic monitoring challenges: Challenge 1: Network baselines. But implementing network traffic monitoring tools can also pose a series of challenges that range fromĭifficulty in creating network baselines to trouble finding the right tools and strategies for monitoring content in a proxied environment. Top seven network traffic monitoring challenges Richard Bejtlich Network traffic monitoring is often touted as a way for enterprises to meet performance, security and compliance goals. ![]() Top Seven Network Traffic Monitoring Challenges This Expert E-Guide from details the top seven challenges and how to address them. ![]() Top Seven Network Traffic Monitoring Challenges Network traffic monitoring is frequently leveraged as a way to manage performance and compliance goals, but the technique presents its own set of challenges from selecting the right tools to implementation to management.
