Include applications stored on-site alongside cloud services that users rely on.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Automation helps you discover connected devices and apps and model device dependencies. <b>Application and network discovery tools <\/b>scan endpoints, and data flows to assess network topography.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Manually assessing network maps is also possible but time-consuming. Maps also become outdated without regular updates, while automation tools adapt as network traffic changes.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">The outcome of this exercise should be a clear map of critical data flows, including a list of device and application dependencies.<\/p><h3 class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h3__gewqv\" data-testid=\"heading\">2. Decide how to collect network traffic<\/h3><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Now, we need to create systems to extract information from data sources. There are two basic approaches: agent-based collection and agentless collection.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\"><b>Agent-based systems<\/b> deploy agents on devices. Agents are tiny apps that continually collect data about performance, availability, traffic volume, and inbound or outbound communications.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Agents are essential to monitor network traffic at the level of network packets. However, they can interfere with network speeds or lead to storage problems.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\"><b>Agentless collection<\/b> does not rely on agents to gather information. These solutions generally use protocols like the Simple Network Management Protocol (SNMP) or APIs supplied by data source vendors.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Agentless systems send monitoring queries to apps or devices. Targets respond, supplying data about their availability and security status. Agentless collection is a slightly less detailed way of analyzing network traffic. However, network traffic data is still sufficient for most monitoring purposes.<\/p><h3 class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h3__gewqv\" data-testid=\"heading\">3. Configure context-based network visibility<\/h3><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Now, set the rules for network traffic analysis. Robust network visibility is not just about collecting masses of network traffic. IT teams must also<b> consider network context<\/b> to understand the reason for data spikes or speed issues.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Contextual information includes <b>user authentication requests, app usage, or threat intelligence<\/b>. This information may explain why traffic is spiking on particular devices. The absence of contextual data could indicate an imminent threat.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Combining raw network traffic data with situational knowledge empowers security teams and technicians. The more you know about your network environment, the easier it is to identify problems and avoid security incidents.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Choose a traffic analysis solution that integrates with threat detection and response systems. Even better, opt for a network visibility solution that <i>blends<\/i> threat detection and performance monitoring.<\/p><h3 class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h3__gewqv\" data-testid=\"heading\">4. Check network restrictions<\/h3><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Before turning on network traffic monitoring, engineers must check local network restrictions and verify that monitoring will function properly.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">For example, <b>encrypted traffic <\/b>may not be visible to tracking systems without key sharing. Bandwidth restrictions may apply, and some <b>ports may be inaccessible<\/b> to monitoring protocols. <b>Monitoring cloud data <\/b>can also be challenging. Providers operate their own data restrictions, potentially compromising network visibility.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\"><b>Legacy systems<\/b> often co-exist with cloud implementations. Engineers should ensure traffic monitoring covers all data sources and replace applications or devices you cannot monitor. Firewall appliances and <a class=\"Link_inherit__NP_8V Link_medium__XEV_Z Link_noTextDecoration__GhdxD Link_aTagRoot__8wRP7 Hyperlink_link__umZi8\" href=\"\/en\/learn\/network-security\/network-segmentation\/\"><b>network traffic segmentation<\/b><\/a> can also influence data collection.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\"><b>Compliance<\/b> is another consideration. Privacy regulations prohibit the unauthorized collection of private data. Network traffic collection should not extend to user or customer identities without consent.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Finally, network traffic analysis must <b>consider malicious threats<\/b>. Can monitoring tools identify suspicious traffic and work around obfuscation techniques? If not, alternative solutions may be preferable.<\/p><h3 class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h3__gewqv\" data-testid=\"heading\">5. Decide how to collect tracking data<\/h3><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Collecting network traffic is useless without a <b>secure and accessible storage solution<\/b>. This storage facility guards your collection tools and is a reliable destination for harvested traffic.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Separating tracking systems from general network traffic is advisable. Separation protects data from external attacks or outages. The best solution is using a secure cloud-based provider to store tracking data or building separate on-premises hardware.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Virtualized storage solutions suit multi-cloud or single-cloud networks with low on-premises involvement. Hardware is ideal for traditional office networks with few cloud components.<\/p><h3 class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h3__gewqv\" data-testid=\"heading\">6. Put in place traffic analysis tools<\/h3><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">IT teams need the ability to <b>view, analyze, and use network traffic data.<\/b> Beware: not all monitoring systems include<b> visualization panels <\/b>and ways to aggregate tracking logs.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Without visualization features, engineers face libraries of text files, and it takes hard labor to extract data from tracking logs. Unless you are comfortable with those processes, choose a tracking partner that makes analysis easy.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Effective solutions allow users to<b> generate reports <\/b>for audits and investigations. They enable <b>application and user-level traffic analysis. <\/b>Automating routine security tasks and network traffic map generation are also helpful features.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Don&#8217;t forget: Systems for analyzing network traffic also need <b>alert functions<\/b> to trigger user responses. Choose network traffic analysis solutions with customized alerts and robust measures to detect false positives.<\/p><h3 class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h3__gewqv\" data-testid=\"heading\">7. Test network traffic analysis before going live<\/h3><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Deploy network traffic analysis <b>gradually<\/b>. Measured deployment gives you time to check components are functional and deliver the data you need. Rushed implementations waste resources and may lead to inadequate long-term coverage &#8211; giving you a false sense of security.<\/p><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Begin by tracking a small group of data sources. Start with a single data server or cloud-based application. Only expand network traffic analysis when you know that everything works as designed.<\/p><h2 id=\"how-nordlayer-can-help-you-achieve-network-visibility\" class=\"Heading_root__vbfeI Heading_heading20__p7mXS Heading_primary__3VZgz Heading_normal__hJuNy RichText_h2__2iijA\" data-testid=\"heading\">How NordLayer can help you achieve network visibility<\/h2><p class=\"Text_text__rSWMU RichText_paragraph__DNqK4 Text_body50___cwDR\" data-testid=\"text\">Network traffic analysis identifies performance and security problems<i> before<\/i> they impact business operations.
