What Is a White Hat? The Ethical Side of Hacking

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 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:

• Reverse 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

These days, 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:

Degree types for a white hat

Although some white hat hackers develop their expertise from working with computers, many get 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 cybersecurity principles, practices, and techniques. A full-time student might obtain a master's degree in cybersecurity in one to two years. 

Alternatives to getting a degree 

If you aren't interested in going to college, you can pick up valuable ethical hacking experience by joining the military 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 $1,199 and retakes cost $450. Applying to take the exam costs $100. 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. 

Salary 

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 the United States is $113,712 (March 2022) [1].
