Network forensics tools and software can help forensic investigators solve cyber attack cases faster by identifying the evidence left by the adversaries. Moreover, this article will teach you how network forensics tools and software prevent more cyberattacks from occurring.
Daily, people confront cyberattacks in the world without the preparation of any security measures or data backup, which takes a lot of time and effort for professionals to get the systems and servers back to work. Let’s continue!
Network security experts and digital forensic investigators employ network forensic tools as software or hardware applications to gather, monitor, examine, and preserve digital evidence from computer networks and networked devices.
Through the analysis of network traffic, the detection of anomalies, and the recovery of important data for judicial and investigative purposes, these technologies aid in the investigation of security incidents, cybercrimes, and network-related problems.
Many different types of network forensic tools offer a wide variety of functionality for network investigation and evidence gathering.
To look into security incidents, network breaches, and other cybercrimes, network traffic and activities must be
There are several types of network forensics:
| S.No. | Types | Facilities |
| 1. | Full Packet Capture (FPC) | It entails recording and archiving all network traffic information, including packet contents, for further study.
This makes it beneficial for in-depth investigations since it enables investigators to reconstruct network sessions and study the entire transmission. |
| 2. | Session Data Analysis | The goal of this kind of network forensics is to record and examine data about network sessions, such as
a) Session Metadata, b) Session Initiation, and c) Termination Details. It aids investigators in comprehending communication patterns and flow. |
| 3. | Log Analysis | Log-based network forensics entails the examination of logs produced by various network devices, including
a) Routers, b) Firewalls, and c) Intrusion Detection Systems. These logs can offer useful information regarding security incidents and network occurrences. |
| 4. | Network Flow Analysis | Network flow data is a collection of compiled details on network connections, including
a) Source & Destination IP Addresses, b) Ports, and c) Data Transfer Rates. Network traffic abnormalities and trends can be found with the aid of flow analysis. |
| 5. | Protocol Analysis | Examining network traffic at the protocol level is the main goal of protocol analysis.
Understanding how communication works and identifying any protocol-specific anomalies or assaults, entails analyzing and understanding network protocols. |
| 6. | Payload Analysis | Payload analysis entails looking at the information included in network packets to determine
a) Malicious Payloads, b) Malware, or c) Data Exfiltration Attempts. It is especially important for identifying and reducing cyber risks. |
