What is Cyber Forensics blog article

Digital forensics, or cyber forensics (sometimes called computer or internet forensics) fall into several different categories. You will find everything from database forensics and disk and data capture, to mobile device, file and email analysis and network forensics. It’s a complex and hard to define subset of network security, in part because it’s a relatively new practice. Until the early 1990’s, most cyber forensics was performed using live analysis, with fingers on the keyboard. As more devices were developed, packed with complex functions and programs, the more traditional methods of eye-balling potential threat became obsolete, with businesses relying instead on automated technology.


You’d be forgiven for thinking that cyber forensics is now performed entirely independently of skilled human analysts – but this simply isn’t the case. New tools, open source or paid, are developed daily to help network security professionals keep up with threat, but there is a dire need for more skilled forensics professionals. Let’s first explore the tools, technologies and platforms available to help secure your network connections and discover any lurking threat. Then we will break down the need for more skilled forensics professionals, and where you can find the information you need to take your first step toward a new career in internet forensics.


What is Cyber Forensics?

Cyber forensics is simply the gathering and analysis of information from a computer or device, which can be used as proof of a cyber-attack.  Finding malware in the software of the device is the ultimate goal, easily discovered when professionals analyse device endpoints for entering and exiting malicious files or data. Computer forensics is critical in finding vulnerabilities, attackers and even denial of service attacks. Forensics professionals often follow a very structured process in their work.

  • Make a digital copy of the data under investigation, to ensure no data is lost in the investigation process.
  • Verify and authenticate the digital copy that was just created.
  • Ensure no data has been changed in the copying process, and track where the data came from, and where it is now stored. Ensuring the copied data is forensically appropriate.
  • Recovery of any deleted files due to attack, and tracking these changes back to their root, the cyber-attacker.
  • Using keywords to quickly search for data that might lead to discovery of the attacker or any lurking malicious software within the system.
  • Create a technical report of all findings and how to avoid this issue in the future, based on in-depth research.

Internet Forensics Tools

Usually, Sangfor Team suggest to install Sangfor NGAF which is a Next Generation Firewall NGFW, Cyber Command which is Network Detection and Response NDR tools for the enterprises, and Endpoint Secure that is Endpoint Detection and Response EDR tool. All these three tools are super powerful and give you a 360 degree holistic view on what happens at your network.


Digital forensics tools are either hardware or software designed to aid in the recovery of digital evidence of cyber-attack, and preservation of data or critical systems.


Cyber security professionals rely on technology to enable their investigations, and this need has created a massive market for forensics analysis tools. A list of the main types of digital forensics tools often includes:

  • Disk Forensic Tools
  • Network Forensic Tools
  • Wireless Forensic Tools
  • Database Forensic Tools
  • Malware Forensic Tools
  • Email Forensic Tools
  • Memory Forensic Tools
  • Mobile Phone Forensic Tools

Cyber Forensics Platforms

There are quite a few open-source forensics platforms available on the internet, and downloaded with just a few clicks. Open source forensics platforms are a great way to start your digital forensics journey, and a great stepping stone toward more powerful, professional forensic analysis tools and platforms with more features and functions. For first-timers, check out any one of these highly-rated, open-source platforms:
