Practical Windows Forensics

Overview of this book

Over the last few years, the wave of the cybercrime has risen rapidly. We have witnessed many major attacks on the governmental, military, financial, and media sectors. Tracking all these attacks and crimes requires a deep understanding of operating system operations, how to extract evident data from digital evidence, and the best usage of the digital forensic tools and techniques. Regardless of your level of experience in the field of information security in general, this book will fully introduce you to digital forensics. It will provide you with the knowledge needed to assemble different types of evidence effectively, and walk you through the various stages of the analysis process. We start by discussing the principles of the digital forensics process and move on to show you the approaches that are used to conduct analysis. We will then study various tools to perform live analysis, and go through different techniques to analyze volatile and non-volatile data.

Exploring logs

The most ubiquitous connectivity options of the corporate network to the Internet is to use a proxy server. Moreover, all protocols except HTTP and HTTPS are blocked by a firewall. Therefore, we consider this particular scheme. A proxy server is a server that is an intermediary between the client and server. Proxies can be used for almost any network protocol, but they are most often used for the web traffic for HTTP and HTTPS.

In this case, a forensics analyst usually has a data proxy server. Proxy logs are invaluable in analyzing what URL is accessing the corporate network machines. Analysis of the logs of the proxy server allows you to quickly identify which workstations are exposed to a malicious resource. This is done much faster than in the analysis of each client machine.

Typically, proxy logs include not only the time and IP address of the client and the URL, but they also include the status of the HTTP response and the username:

  • Unix timestamp (sec.ms)

  • Response time ...
