The term white hat refers to an ethical hacker whose job involves hacking into computer systems to detect security risks. The term and its definition derive from old movie westerns, where the law-abiding heroes always wore white hats. Unlike those who break into computers to destroy or steal data, white hat hackers have good intentions.

What does a white hat do?

When a company needs to test its information system’s security, it hires white hats to attempt to hack information systems. This ethical hacking process helps detect vulnerabilities in a system. Depending on the company you work for, your duties as a white hat hacker might include:

  • Reversing engineering malware and viruses

  • Analyzing attacks and security incidents for their root causes

  • Scanning a target network with vulnerability scanners

  • Designing plans of attack to try and exploit (and then patch) vulnerabilities

  • Providing technical support

  • Reviewing and updating documentation  

Jobs for white hats

The demand for ethical hackers is higher than ever in both private and public sectors. 

Private sector vs. government jobs

There are many types of private sector companies that need stringent security for their information systems. Examples include:

  • Financial institutions like banks, credit card companies, and mortgage companies

  • Technology companies 

  • Educational institutions

  • Aerospace companies

  • Cell phone companies

  • Health care businesses

  • Utility companies

  • Large retail and wholesale establishments

  • Entertainment and media companies

  • Artificial intelligence (AI) companies

Ethical hackers who want a government job might work for the Communications Security Establishment, the Canadian Special Operations Forces Command, or the Canadian Security Intelligence Service. These are just a handful of government agencies that hire white hats to secure their information systems. 

Some common job titles for ethical hackers in the private and public sector include:

  • Data security analyst

  • Data security manager

  • Network administrator/manager

  • Network security consultant

  • Penetration tester

  • Security engineer

  • Vulnerability assessor 

Ethical hacker skills 

There are two types of skills that help with job performance: technical skills and workplace skills. Technical skills are learned through training or education, while workplace skills are those that involve your personality or work ethic. To become a white hat, plan to develop a unique combination of technical and workplace skills, including:

  • Computer programming skills

  • Databases and networks

  • Cryptography (study of encryption and decryption)

  • Web applications and wireless technologies

  • Problem-solving

  • Organization

  • Communication

  • Ability to remain calm in high-pressure situations

Degree types for a white hat

Although some white hat hackers develop their expertise from working with computers, many have bachelor's degrees as well. Degrees that might benefit ethical hackers include:

  • Computer science

  • Computer engineering

  • Information technology

  • Cybersecurity

When you're ready to apply for a position as a white hat, you'll likely need a strong working knowledge of operating systems like Linux, Kali Linux, and Windows and extensive experience writing code. Types of scripting and programming languages to learn and master include:

  • ASP

  • C

  • C++

  • HTML

  • JSP

  • JavaScript

  • PHP

  • Python

  • SQL 

Should I get a master’s degree?

You may not need a master's degree to get a job as a white hat hacker. But if you have an undergraduate degree in a field like math, physics, computer science, or engineering, you can go on to get a Master of Science in Cybersecurity. 

This program may offer opportunities to develop a deep understanding of cyber security principles, practices, and techniques. A full-time student might obtain a master's degree in cyber security in one to two years. 

Alternatives to getting a degree 

If you aren't interested in going to college, one way that you can pick up valuable ethical hacking experience is by joining the Canadian Armed Forces and advancing up a cybersecurity or intelligence track. Another bonus of joining the military is the security clearance you'll likely get while you're there. This is a valuable asset to many public and private sector employers when it's time for you to move on from the military.

Certifications for career prospects

If you're hoping to work as an ethical hacker, certifications can give you a chance to show employers that you have those skills. The Certified Ethical Hacker (CEH) Certification offered through the EC-Council (International Council of E-Commerce Consultants) is one of the most respected and comprehensive certifications in the industry. 

This program is globally recognized, and participants who complete it might get top positions as ethical hackers. To enroll in the course, you must have at least two years of experience in information security and pass a pre-enrollment exam. The CEH exam costs $1,199USD and retakes cost $450USD. Applying to take the exam costs $100USD. The class focuses on these topics and more:

  • Cryptography

  • Enumeration

  • Firewalls

  • Footprinting

  • Honeypots

  • Latest trojans, worms, and viruses

  • Penetration testing

  • Server hacking

  • Session hijacking

  • Social engineering

  • SQL injection

Part of the process of getting this certification is agreeing to the EC-Council's code of ethics, stating that participants of the program must always protect intellectual property and promise never to engage in malicious hacking activities. 


As with most jobs, your salary as an ethical hacker depends on your level of education and experience. According to Glassdoor, the average salary for an ethical hacker in Canada is $91,447 (January 2024) [1].
