In the previous chapter, we looked at various network protocol captures that define evidence in motion or data captured while in action. However, it is crucial for a network forensic investigator to have a brief knowledge of the various types of logs generated at the endpoints while traveling. These logs prove to be extremely handy when the scenario doesn't contain network captures, and it is up to the investigator to deduce and conclude the forensic investigation and reach a definitive result. Consider a situation where a company named Acme Inc. has faced a massive breach of customer data through its website, and the company hasn't kept any packet-capture files for the incoming data. In such cases, the forensic investigation solely relies on the logs generated at various endpoints, such as application servers, databases, and firewalls, as shown in...

Overview of this book
Network forensics is a subset of digital forensics that deals with network attacks and their investigation. In the era of network attacks and malware threat, it’s now more important than ever to have skills to investigate network attacks and vulnerabilities.
Hands-On Network Forensics starts with the core concepts within network forensics, including coding, networking, forensics tools, and methodologies for forensic investigations. You’ll then explore the tools used for network forensics, followed by understanding how to apply those tools to a PCAP file and write the accompanying report. In addition to this, you will understand how statistical flow analysis, network enumeration, tunneling and encryption, and malware detection can be used to investigate your network. Towards the end of this book, you will discover how network correlation works and how to bring all the information from different types of network devices together.
By the end of this book, you will have gained hands-on experience of performing forensics analysis tasks.
