Network Activity Monitoring for Remote Sites

Network activity monitoring for remote sites is a task often expected of IT teams where no local IT support exists. However, installing client or agent software on devices in remote sites can be a costly and time-consuming process. It can also be an ineffective solution for public access or BYOD networks where IT teams are unable to install agent software onto end users´ devices.

Several agent-free solutions exist to monitor network activity on remote sites. IT teams can gather network activity information using SNMP or WMI, but these services are limited to alerts or high level information and fail to provide the analysis required to troubleshoot LAN and link problems associated with remote sites. This leaves two solutions – flow analysis tools and network packet capture.

Flow analysis tools provide visibility into traffic travelling through the network at remote sites but fail to provide information about what is contained within packet payloads. By comparison, network packet capture solutions extract metadata from network packets so that IT teams can drill down into the metadata to see what protocols and applications are being used, who is using them, and from where.

How Network Packet Capture Solutions Work

Network packet capture solutions work using wire data analytics to extract metadata from network packets. The extracted data is presented in readable format to IT teams, who can drilldown through the data in order to:

  • Search and monitor network activity from every location.
  • Monitor network performance and utilization in real time.
  • Troubleshoot network issues and identify security threats.
  • Monitor bandwidth usage to identify bottlenecks.
  • Identify redundant or unused network resources.

When a network packet capture solution is monitoring a LAN (Local Area Network), the solution connects to the network via the core switch and a monitoring port in order to collect traffic data and deliver it in readable format to a “Central Management” device – typically a computer with a network traffic database and web server connected to the network.

Network activity monitoring for remote sites follows the same process with sensors deployed on physical or virtual platforms at remote sites. Data from the remote sites is stored centrally to provide a single reference point for all traffic and security information across local and remote networks. IT teams can log into the Central Management device to see what is happening within their remote networks.

With network activity monitoring for remote sites, IT teams can monitor the whole network. Alerts can be sent when specific network events occur and historical reports can be scheduled by username, user group, IP address, subnet, file name or web address – historical data used to conduct network forensics and identify trends that cannot be identified using real time data alone.

Network Activity Monitoring for Remote Sites from LANGuardian

LANGuardian from NetFort is an agent-free network packet capture solution that is an ideal tool for IT teams tasked with network activity monitoring for remote sites. Quick to install and easy to configure, LANGuardian drills down to the minutest detail to provide detailed network traffic visibility and analysis, without being obtrusive or affecting network performance.

Suitable for multiple network security and operational use cases, LANGuardian provides a single point of reference for network and user activity monitoring, and includes key features such as a versatile search engine, fast alert mechanisms and robust reporting tools. With LANGuardian, IT teams can list and track servers, applications and users on a network and pinpoint the causes of poor network performance.

In addition to monitoring traffic to file shares and SQL databases to provide compliant audit trails, LANGuardian identifies applications using random port numbers, or standard port numbers for non-standard purposes in order to enhance network security. LANGuardian can also mitigate the risk of a ransomware attack by allowing IT teams to configure alerts for file rename trends.
