![]() Packet source selection. Network administrators should focus on collecting data from select points in the network with the most visibility into other parts - instead of connecting to and monitoring every single packet source in the network.Flexibility. Technologies used should be flexible and adapt to changes in the network on their own, so that maintenance and upgrade cycles occur less frequently.īest practices for implementing and maintaining network visibility architectures include:.Sustainability. Technologies used in a visibility architecture should be easily upgradable to accommodate increasing speeds and newer components of the network.Scalability. Network visibility tools should be able to accommodate rising network connectivity speeds and the consequent increase in packet volume, as well as the general size of the network, including new geographical locations and infrastructure.Network visibility best practicesĪ good network visibility architecture should be scalable, sustainable and flexible. Linking these elements in an efficient way and maintaining performance while also making all data visible becomes more difficult as networks become more complex and have more network segments to account for. Also, network performance monitoring tools can be overloaded when fed data they can't parse, or too much data.Ĭomplex networks. Modern networks consist of a wide spectrum of network monitoring and analysis tools such as firewalls, intrusion prevention systems, data loss prevention ( DLP) and antimalware software. Updating the physical network architecture may also make existing tools less effective, as they may lack the processing power for higher network bandwidths and throughputs. Modern network switches, for example, only come with a couple of switched port analyzer ( SPAN) ports. Visibility tool limitations. Visibility is usually maintained and monitored by a combination of network visibility tools, each with its own specific purposes and limitations. In some cases, it also conceals security vulnerabilities. ![]() This is because they may have been configured for on-premises networks before the rise of the cloud, and now cannot adapt to the new type of network.Įncrypted data. Encrypted network traffic makes up a considerable portion of modern network traffic and makes visibility more difficult. Many traditional network monitoring tools and security measures don't work as well in the cloud, such as Simple Network Management Protocol (SNMP). For example, it is difficult to measure application-level traffic to and from cloud data centers because cloud platforms often have their own communication protocols and security architecture. Visibility blind spots. While the cloud and mobile offer considerable performance advantages, they create blind spots in a network visibility architecture. Many enterprises let mobile users connect directly to the cloud, in which visibility will suffer. Software-defined WAN ( SD-WAN) presents a solution to this problem. Remote work. Virtual private networks (VPNs) enable employees to work securely from a remote location but sacrifice the visibility that on-premises employee technology offers. Below are some specific, common challenges organizations face in maintaining network visibility: Having network visibility allows the enterprise to parse noisy data environments and ensure sensitive data is accounted for and properly secured.ĭownload this entire guide for FREE now! Enterprise network visibility challengesīroad network visibility challenges involve adapting to the increasing speed and scale of modern enterprise networks without sacrificing performance. As this data becomes more complex, network monitoring becomes more difficult, and potential threats become more likely. The growing volume and variety of data that typical enterprise networks carry make network visibility an increasingly important priority.Įnterprises are accountable for the data that travels on their networks. Network visibility allows organizations to have a better awareness of the behavior of traffic on their networks, and can use it to improve the efficiency, security and performance of those networks. Network visibility allows companies to have more control over their networks and to make better decisions regarding data protection and flow. ![]() It also serves as the foundation for a healthy network security infrastructure. Taking a proactive approach to network visibility allows enterprises to better monitor network traffic and network performance. The term is often used to refer to the various tools enterprises use to increase awareness of their data and other network contents. Network visibility is an awareness of the components and data within an enterprise computer network.
