Visibility helps your security team understand the entities connected to the network. Network Traffic Analysis should also provide proper context- which users are on your network, what kind of data they are sharing, where they are accessing the web, what devices they are interacting with etc. This kind of context-driven visibility is critical for security teams when developing mitigation steps and forming a risk management strategy, like implementing network segmentation for zero trust.
Solutions should monitor the entire digital enterprise from the private network to multiple cloud environments, especially with the increased transition to the cloud.
An NTA solution should immediately detect advanced threats that might have originated within the business or bypassed the perimeter using multiple analytical techniques like machine learning and behavioral modeling. It should also be combined with threat intelligence to map a local threat to a global campaign for efficient mitigation by security teams.
Network Traffic Analysis should be able to analyze encrypted traffic for threats. With over 70 percent of malware being encrypted and the recent rise in encrypted traffic, this also helps ensure organizations’ cryptographic compliance. Additionally, they detect threats such as DDoS attacks, command and control attacks, insider threats, illicit crypto mining, unknown malware, and ransomware.
The advanced analytical techniques and combination of context-driven enterprise-wide visibility results in accelerated threat response. Every attack begins with early signs of suspicious activity, such as the use of restricted ports or protocols, unusual remote access, or port scanning.
Continuous network traffic analysis can detect this behavior and identify the target, where the threat has spread laterally, and where the threat originated. This allows security analysts to make immediate corrections. Lastly, NTA solutions should also integrate with existing security controls so that you can extend response and investigation across the applications, network, cloud, and endpoints.
Network traffic analysis is crucial for monitoring network activity and availability to detect attacks, maximize performance, and identify anomalies. Alongside endpoint data, log aggregation, and UEBA (User and Entity Behavior Analytics), network traffic is a core of the security analysis and comprehensive visibility to discover threats early and extinguish them fast. When choosing an NTA solution, consider the data sources you need information from, the critical points on the network where they converge, and current blind spots for efficient monitoring. As NTA complements your Security Information and Event Management (SIEM) solution, you’ll gain greater visibility into your users and environment.
