Network Forensics

Our skilled and experienced network forensics investigators are at your disposal.

Network forensics refers to monitoring, gathering, and analyzing network traffic to uncover the source of attacks, insider abuses, intrusions, intellectual property thefts, industrial espionage, or information leakages that occur on a network. While computer forensics focuses on static data on a seized storage device, network forensics deals with data in transit that is volatile or always changing. Solving such cases and dealing with dynamic data require the use of network forensic tools and methodologies.

Network forensics is more difficult to carry out because evidence almost always traverses the network, mostly not stored, and then may be erased forever. For that reason, if a plan is not in place to capture and store network data before any incident occurs, it wouldn’t be possible to perform a healthy network forensic investigation.

Network forensic capture and analysis tools used by DIFOSE experts enable them to monitor networks and gather required information about anomalous traffic related to incidents. Synergizing these tools with other network devices such as firewalls, IPS, IDS, SIEM and DLP solutions provides the best possible results in terms of both solving the cases and providing insight for more secure networks in the future.

Regardless of the scope and complexity of the case at hand, DIFOSE will be at your disposal with our experience, know-how, and technological capacity. Depending on the type of case, we use TAP or SPAN methods to collect data from your network. We collect your network data in PCAP format with our devices that have network monitoring or data collection capabilities without any packet loss in networks from 1Gbe to 100Gbe. After data collection, we perform DPI, flow, content, and application analysis along with cybersecurity and forensic analysis, and lastly provide you with a detailed report.
