Network Forensics involves recording, capturing, and analyzing network packets to determine where security assaults originate. In addition to identifying intrusion patterns, a network forensics study also looks into the tactics used during attacks. Data collection from multiple websites and network devices like firewalls and intrusion detection systems is necessary for network traffic analysis. Additionally, possible threats can be tracked, avoided, and studied via network forensics. A network forensic investigation is useful when finding leaks, suspicious traffic network activity, or thefts. This kind of inquiry tries to find and analyze network activity on a system that is thought to have been compromised by cybercriminals. Thus, these types of networks create a positive influence on the global network forensic market. According to a research report by Astute Analytica, the Global Network Forensic Market growing at a compound annual growth rate (CAGR) of ~18.9% over the projection period from 2021 to 2027. Types of Network Forensic Ethernet: The information on this layer can be used by the user to filter events. Only if they are left unencrypted during transmission or receipt is it feasible to recreate email, attachments, website pages, and other network data. Due to the data’s direct connection to a host, data collection at this level is advantageous Encrypted Traffic Analytics: An encrypted traffic analysis examines communication to check for malicious traffic, such as that malware or other threats, by looking for suspicious TLS features, like those coming from unusual networks or servers. Making databases of fingerprints based on generated data is another approach to decrypting encrypted traffic, although it has drawn criticism for being unreliable and open to a hacker attack. TCP/IP: TCP packets are directed through networks (for example, the Internet) by network layer protocols like Internet Protocol (IP), which combine source and destination information before sending it to the routers dispersed throughout the network. Because cellular packet networks like GPRS employ identical protocols, the IP approaches are also applicable to them. The Internet: The Internet can be used to gather several kinds of digital evidence, such as email, online browsing, newsgroups, synchronous chat, and peer-to-peer communication. Web server logs can be examined to determine when (or if) suspects accessed information that is relevant to a crime. Email headers are easily falsified and can therefore include important evidence, making it possible to use email forensics to verify the precise origin of damning materials. By employing network forensics, it is possible to identify the user of a specific computer by extracting information about the user account from the traffic on a networking service. North America and Europe anticipate making their biggest profits from vendors of network forensics solutions. The main cause of it is the increased global focus on security technology and research and development (R&D), especially in the developed nations of the United States and Canada. Asia Pacific is likely the market’s fastest growth. Bring Your Device (BYD) rules and increasing Internet of Things device use in organizations are driving this region’s growth. In the upcoming years, the Network Forensics Market is anticipated to expand significantly due to the rising significance of cloud-based solutions, machine learning, artificial intelligence (AI), integrated security solutions, and security team cooperation.
