Colasoft Announces Release of Capsa Network Analyzer v8.2

colasoft-category-logoFebruary 23, 2016 – Colasoft LLC, a leading provider of innovative and affordable network analysis solutions, today announced the availability of Colasoft Capsa Network Analyzer v8.2, a real-time portable network analyzer for wired and wireless network monitoring, bandwidth analysis, and intrusion detection. The data flow display and protocols recognition are optimized in Capsa Network Analyzer 8.2.

Capsa v8.2 is capable of analyzing the traffic of wireless AP with 2 channels. Users can choose up to 2 wireless channels to analyze the total traffic which greatly enhances the accuracy of wireless traffic analysis. Hex display of decoded data is added in Data Flow sub-view in TCP/UDP Conversation view. Users can switch the display format between hex and text in Capsa v8.2.

Besides the optimizations of Data Flow sub-view in TCP/UDP Conversation view, with the continuous improvement of CSTRE (Colasoft Traffic Recognition Engine), Capsa 8.2 is capable of recognizing up to 1546 protocols and sub-protocols, which covers most of the mainstream protocols.colasoft-network-analyzer-v82

“We have also enhanced the interface of Capsa which improves user experience”, said Brian K. Smith, Vice President at Colasoft LLC, “the release of Capsa v8.2 provides a more comprehensive network analyze result to our customers.”

Capsa is an easy-to-use packet sniffer (network analyzer or network sniffer) for network monitoring and troubleshooting purposes. It performs real-time packet capturing, 24x7 network monitoring, reliable network forensics, advanced protocol analyzing, in-depth packet decoding, and automatic expert diagnosing. By giving you insights into all of your network's operations, Capsa makes it easy to isolate and solve network problems, identify network bottleneck and bandwidth use, and detect network vulnerabilities.

How to Detect P2P (peer-to-peer) File Sharing & Torrent Traffic & Users with Capsa Network Analyzer

capsa-network-analyzer-detect-p2p-file-sharing-torrent-traffic-1aPeer-to-Peer file sharing traffic has become a very large problem for many organizations as users engage in illegal (most times) file sharing processes that not only consumes valuable bandwidth, but also places the organization in danger as high-risk connections are made from the Internet to the internal network and malware, pirated or copyrighted material or pornography is downloaded into the organization’s systems. The fact is that torrent traffic is responsible for over 29% of US Internet's traffic in North America, indicating how big the problem is.

To help network professionals in the P2P battle, we’ll show how Network Analyzers such as Colasoft Capsa, can be used to identify users or IP addresses involved the file sharing process, allowing IT departments to take the necessary actions to block users and similair activities.

While all network analyzers capture and display packets, very few have the ability to display P2P traffic or users creating multiple connections with remote peers - allowing network administrators to quickly and correctly identify P2P activity.

One of the main traffic characteristics of P2P host traffic is that they create many connections to and from hosts on the Internet, in order to download from multiple sources or upload to multiple destinations.

Apart from using the correct tools, network administrators and engineers must also ensure they capture traffic at strategic areas within their network. This means that the network analyzer must be placed at the point where all network traffic, to and from the Internet, passes through it.

The two most common places network traffic is captured is at the router/firewall connecting the organization to the Internet or the main switch where the router/firewall device connects to. To learn how to configure these devices and enable the network analyzer to capture packets, visit the following articles:

While capturing commences, data will start being displayed in Capsa, and thanks to the Matrix display feature, we can quickly identify hosts that have multiple conversations or connections with peer hosts on the Internet.

By selecting the Matrix tab and hovering the mouse on a host of interest (this also automatically selects the host), Capsa will highlight all conversations with other IP addresses made by the selected host, while at the same time provide additional useful information such as bytes sent and received by the host, amount of peer connections (extremely useful!) and more:
