Network forensics refers to investigations that obtain and analyze information about a network or network events. This field, which is quite new in the field of digital forensics, involves collecting information, obtaining evidence and penetration test It covers the processes of monitoring computer networks and analyzing the data collected from the networks. Network forensics methods vary widely. Some studies monitor all traffic on a network, while others use more specific and targeted observations. Those conducting network forensics may attempt to create digital timelines for network events and collect other types of network usage facts, including IP addresses and encrypted/unencrypted messaging.
Infinitum IT expert team offers network traffic capture and analysis, network performance evaluation, detection of anomalies and misuse of resources, determination of network protocols used, analysis and protection of data collected from multiple sources, security investigations and incident response, and protection of intellectual property for companies. At the same time, our work enables a faster incident response to an attack and provides various methods for predicting future attacks by correlating attacks with traffic data records of previous attacks.
Traditionally, organizations have invested in network forensics when they realized they needed a systematic approach to resolve security and network performance issues more quickly. This is still true, but in the era of 10G and faster networks, forensic service has taken on new and even greater importance as organizations can conduct detailed analysis of the traffic passing their networks at speeds of 5Gbps or higher. Today's networks transmit so much data that the only way to monitor and troubleshoot traffic is to record it first. Therefore, while network forensics is still an invaluable tool for finding evidence of security attacks, it is now a “must have” tool for analyzing modern networks in detail.
The Network Forensic service can be applied to many situations to solve performance, security, and policy issues in today's high-speed networks. Examples include: • Finding evidence of a security attack • Troubleshooting intermittent performance issues • Monitoring user activity for compliance with IT and HR policies • Identifying the source of data leaks • Monitoring business transactions • Troubleshooting VoIP over IP and video.
Three key capabilities are required to facilitate the use of the Network Forensic service: • Data Capture and Recording: The ability to capture and store large numbers of terabytes of data from high-throughput networks, including 10G and even 40G, without dropping or missing any packets. • Data Discovery: Once the data has been saved on the storage medium, the solution will be able to identify specific items of interest eg IP address, application, context etc. It should provide a tool to filter using. To find specific network conversations or individual packets in a timely manner. • Data Analysis: Automated analysis, including expert analysis describing the context of network events, helps IT engineers quickly identify abnormal or other significant network events. Once these are identified they can go in and make the appropriate corrections.
