The White Hat Starter Pack: 5 Free Tools Every CpE Student Must Try
In the world of Computer Engineering, few fields are as mystified—and as critical—as Cybersecurity. We’ve all seen the movies: a guy in a hoodie typing furiously at a terminal, bypassing mainframes in seconds. But the reality of a “White Hat” (Ethical Hacker) is far more disciplined, technical, and frankly, interesting.
If you are a student looking to pivot into InfoSec (Information Security), you don’t need expensive licenses or proprietary hardware to start. The industry is built on powerful open-source tools. Here is your comprehensive “Starter Pack”—five free tools that you should install, learn, and master today.
1. Wireshark: Seeing the Invisible
What it is: The world’s most widely used network protocol analyzer.
Why you need it: Computer networks are the nervous system of the internet. Wireshark lets you perform “deep packet inspection.” It captures data traffic in real-time and lets you read it like a script. You can see exactly what is happening on your network—from a simple DNS request to a suspicious handshake between a server and a malware-infected device.
Learning Goal: Open Wireshark on your home network. Can you identify which packets are coming from your phone? Can you find the HTTP request when you visit a non-secure website? (Note: Only do this on networks you own!)
2. Nmap (Network Mapper): The Cartographer
What it is: A network exploration and security auditing tool.
Why you need it: Before you can secure a network, you need to know what’s on it. Nmap sends specially crafted packets to target hosts and analyzes the response. It can tell you what hosts are available, what services (application name and version) they offer, what operating systems they are running, and what type of packet filters/firewalls are in use.

What it is: A Debian-based Linux distribution aimed at advanced Penetration Testing and Security Auditing.
Why you need it: Kali isn’t just a tool; it’s a toolbox. It comes pre-installed with over 600 penetration testing programs (including Wireshark and Nmap). Installing Kali—either as a virtual machine or a dual boot—is a rite of passage for any security student. It forces you to get comfortable with the Linux command line, file permissions, and the environment where most servers live.
4. Metasploit Framework: Understanding the Attack
What it is: A penetration testing platform that enables you to find, exploit, and validate vulnerabilities.
Why you need it: To be a good defender, you must understand the attacker. Metasploit contains a massive database of known software vulnerabilities (exploits) and the code (payloads) to take advantage of them. In a controlled lab environment (like Metasploitable), you can use this to see how easily an unpatched Windows XP or Windows 7 machine can be compromised. It teaches you the critical importance of patch management.
5. Burp Suite (Community Edition): Web App Security
What it is: A platform for performing security testing of web applications.
Why you need it: Most modern “hacking” happens on the web. Burp Suite acts as a proxy between your browser and the target website. It lets you intercept, inspect, and modify the raw HTTP requests before they reach the server. This is how you find SQL Injection, Cross-Site Scripting (XSS), and logic flaws in web apps.
Final Advice: The Golden Rule
Possessing these tools grants you significant power, and with that comes the ethical responsibility to use them wisely. Never scan, probe, or attack a network or device you do not have explicit, written permission to test. Unauthorized access is a crime in the Philippines under the Cybercrime Prevention Act of 2012 (RA 10175).
