Network Forensics

Most SMEs can not afford to buy a complete Computer Emergency Response Team (CERT). Many large companies also outsource this project. Internal or external teams will have a major impact on the first phase of the survey. We assume that we are forensic contractors. Given the most appropriate circumstances, our forensic team should include multiple titles, but some of them may be retained by the same individual. A very important position is a legal representative.

Computer forensics is to investigate the digital media stored on the computer for the purpose of investigation Mobile forensics is the collection of digital evidence from mobile devices, acquisition of evidence about network traffic, collection of information or intrusion detection For evidence collection, and forensic data analysis. Investigate the pattern of fraud using structured data. Finally, database forensics is a survey of databases and their metadata (content, log files, in-memory data survey, etc.).

Acquisition, collection, and analysis of events occurring in the network are called network forensics. It is also called packet forensic or packet mining. The basic purpose of network forensics is the same. It is to gather information about packets in network traffic, such as mail, query, browsing web content, and collect this information in one source and perform further checks (WildPackets, 2010). Network forensics can be applied mainly in two ways. The first is security-related, monitors the network for suspicious traffic and all sorts of intrusions. In this case network-based evidence may be involved in forensic analysis, since an attacker could delete all log files from infected hosts.

Computer forensics, also known as digital forensics, network forensics, or network forensics, is a rapidly evolving field that includes collection and analysis of evidence from computers and networks. Since computers and the Internet are the fastest growing technology for criminal activity, the demand for computer forensics specialists will increase in the coming years. Computer forensics experts check computer media, programs, data, and log files on computers, servers, and networks. In many fields, we employ computer forensic experts such as law enforcement agencies, criminal prosecutors, military intelligence agencies, insurance agents, and the information security department of the private sector. Computer forensics experts need to know legal knowledge, technical experience on various hardware and software products, good communication skills, motivation to learn and update skills, and problem solving.
