Security Researcher vs. Threat Hunter

A Comparison of Security Researcher and Threat Hunter Roles

Table of contents

The field of information security is ever-evolving, and with the increasing frequency and sophistication of cyberattacks, the demand for skilled professionals in the industry is at an all-time high. Two roles that are essential in the fight against cybercrime are Security Researchers and Threat Hunters. In this article, we will compare and contrast these two roles, their responsibilities, required skills, educational backgrounds, tools and software used, common industries, outlooks, and practical tips for getting started in these careers.

Definitions

A Security Researcher is a professional who identifies Vulnerabilities and Exploits in software, hardware, and networks. They work to uncover weaknesses in security systems and develop solutions to patch them. Security Researchers typically work for software companies, government agencies, or security consulting firms.

A Threat Hunter, on the other hand, is a professional who proactively searches for threats and malicious activity within an organization's network. They use advanced tools and techniques to identify and isolate potential threats, and work to prevent attacks before they occur. Threat Hunters typically work for large organizations or managed security service providers.

Responsibilities

The responsibilities of a Security Researcher include:

• Identifying vulnerabilities and Exploits in software, hardware, and networks
• Conducting penetration testing and vulnerability assessments
• Developing and testing security solutions to patch Vulnerabilities
• Writing reports and presenting findings to stakeholders

The responsibilities of a Threat Hunter include:

• Proactively searching for threats and malicious activity within an organization's network
• Analyzing log data and network traffic to identify potential threats
• Investigating and containing security incidents
• Developing and implementing threat hunting strategies

Required Skills

The skills required for a Security Researcher include:

• Strong programming skills in languages such as Python, C, and Java
• Knowledge of operating systems and networking protocols
• Understanding of Cryptography and Encryption
• Familiarity with penetration testing tools and techniques
• Analytical thinking and problem-solving skills

The skills required for a Threat Hunter include:

• Strong knowledge of networking protocols and security technologies
• Familiarity with SIEM (Security Information and Event Management) systems
• Knowledge of Threat intelligence and threat hunting techniques
• Experience with Incident response and Forensics
• Analytical thinking and problem-solving skills

Educational Backgrounds

A degree in Computer Science or a related field is typically required for both roles. However, it is possible to enter the field with relevant certifications and experience.

For a Security Researcher, a degree in computer science, cybersecurity, or information security is preferred. Relevant certifications include Certified Ethical Hacker (CEH), Certified Information Systems Security Professional (CISSP), and Offensive security Certified Professional (OSCP).

For a Threat Hunter, a degree in computer science, cybersecurity, or information security is also preferred. Relevant certifications include Certified Information Systems Security Professional (CISSP), Certified Ethical Hacker (CEH), and GIAC Certified Incident Handler (GCIH).

Tools and Software Used

The tools and software used by a Security Researcher include:

• Penetration testing tools such as Metasploit, Nmap, and Burp Suite
• Debugging tools such as IDA Pro and OllyDbg
• Vulnerability scanners such as Nessus and OpenVAS
• Reverse engineering tools such as Ghidra and IDA Pro

The tools and software used by a Threat Hunter include:

• SIEM systems such as Splunk and ArcSight
• Network analysis tools such as Wireshark and tcpdump
• Endpoint detection and response (EDR) tools such as Carbon Black and CrowdStrike
• Threat intelligence platforms such as ThreatConnect and Anomali

Common Industries

Security Researchers are employed by software companies, government agencies, and security consulting firms. They may also work for banks, healthcare organizations, and other industries that handle sensitive data.

Threat Hunters are typically employed by large organizations or managed security service providers. They may work in industries such as Finance, healthcare, and government.

Outlooks

The outlook for both roles is very positive. According to the Bureau of Labor Statistics, employment of information security analysts (which includes both Security Researchers and Threat Hunters) is projected to grow 31% from 2019 to 2029, much faster than the average for all occupations.

Practical Tips for Getting Started

To get started in either role, it is recommended to:

• Obtain a degree in Computer Science or a related field
• Obtain relevant certifications such as CISSP, CEH, and OSCP
• Gain experience through internships or entry-level positions
• Participate in bug bounty programs or capture the flag (CTF) competitions
• Stay up to date with the latest trends and technologies in the field

In conclusion, both Security Researchers and Threat Hunters play critical roles in the fight against cybercrime. While there are some differences in their responsibilities, required skills, and tools used, both roles require a strong technical background, analytical thinking, and a passion for cybersecurity. With the growing demand for information security professionals, these careers offer a promising outlook for those looking to enter the field.
