Network Traffic Analysis
Detect suspicious traffic and quickly stop threats on your network
Network Traffic Analytics
What are network traffic analysis solutions?
Network traffic analysis (NTA) solutions provide a way for your team to detect and investigate network-based threats as well as neutralize attacks before significant damage is done.
Network activity often reveals the earliest signs of an attack. It is critical that your security team has the visibility necessary to surface potential threats in your organization’s network traffic and can analyze the data to detect and quickly respond to threats.
Components of NTA solutions:
- Real-time monitoring
- Detection of suspicious activity
- Forensics capabilities
- Machine-based analytics
- Automated and manual response options
Analyzing and detecting network-borne threats is critical — but these are just two steps to stopping a threat to your network. A full-featured network traffic analysis solution allows you to go beyond detection with comprehensive, rapid response, and mitigation capabilities to realize reduced risk to your organization.
Maximize network threat detection with NDR
LogRhythm NDR provides a machine learning (ML)-driven network threat detection and response solution and a built-in MITRE ATT&CK™ Engine that eliminates blind spots and monitors your organization’s network in real time.
Benefits of network traffic analysis solutions
Get real-time visibility into your network
NTA solutions provide visibility into threats across your entire environment — on-prem or in the cloud — that traditional perimeter defense technologies like firewalls and intrusion detection systems (IDS) can often miss. To catch threats such as malicious packets and traffic hiding within routine traffic, your team needs powerful network inspection capabilities to help you see everything that crosses your network.
An effective network security solution also provides the critical visibility you need to quickly analyze threats with real-time traffic profiling, application identification, bandwidth usage, north-south and east-west traffic observation, enriched metadata, and full packet capture.
Detect suspicious traffic with advanced network threat analytics
Unfortunately, most security tools can’t pick up on data exfiltration, lateral movement, command and control (C2), and other activities. NTA solutions, however, can detect these activities through a combination of machine learning (ML), behavioral analytics, and rule-based analytics that help you detect malicious actors on your network and get context into the nature and extent of an attack.
The ideal NTA solution will help you identify malicious network activity with deeper, more intelligent security analytics and corroborate threats through other environmental context and threat intelligence sources to ensure threats are quickly detected and mitigated.
Remediate malicious network activity quickly
NTA solutions are great at providing visibility to your network and detecting threats and suspicious activity, but this emerging solutions area often lacks in response capabilities. Gartner acknowledges the need for response assistance in their Market Guide for Network Traffic Analysis1 writing, “Although the primary use of NTA tools is detection, organizations expect more help from the tools when it comes to investigating and mitigating an incident.”
These response capabilities, often referred to as security orchestration, automation, and response (SOAR), are critical to remediating threats. Your NTA solution should offer automated investigation and response actions as well as playbooks to help your team reduce response times and stop an attack before it becomes a damaging breach.
