Top 3 Tools for Computer Forensics and Security Professionals

Top 3 Tools for Computer Forensics and Security ProfessionalsComputer forensics and security is an emerging profession. Computer security experts use a number of tools to identify vulnerabilities in computer networks and fix them before hackers strike. If you're considering a career in computer forensics, you'll most certainly become familiar with one or all of these tools as part of your study or career. 

1. Nmap

Nmap, or network mapper, is a tool that scans computers or entire networks for open ports and discrete information. Using Nmap, you can determine which services are running on any computer and even discover the operating system of the computer in question. Nmap helps computer forensics professionals accomplish the following tasks:

  • Discovering weaknesses in network firewalls
  • Identifying services running on each computer in a network
  • Determining if a computer reveals more information about itself than it should

2. Wireshark

Wireshark is an application which sniffs all the traffic on a computer network. Computer security experts use Wireshark to locate if any data is being sent in the clear. If passwords are being sent in clear text, hackers can get on your network and acquire people's passwords just by running this application. Wireshark can:

  • Determine if any sensitive information is being sent across the network in clear text
  • Impersonate other computers on the network in order to locate vulnerable points in network architecture
  • Detect odd behavior on the network that could signify a break in

3. Nessus

As a computer forensics student and professional, you'll most certainly use Nessus. It's a software suite that, much like antivirus software, contains a database of the most up to date hacks available. Using Nessus, you can:

  • Scan a computer or a network for potential vulnerabilities
  • Apply security patches which can fix any security holes on your network
  • Simulate a break-in in order to protect your network from intruders

These three tools are important weapons for any computer security expert. A computer forensics course at IADT will give students the skills and techniques necessary to understand this software and know what to do with the data they reveal.
