Security Researcher

Article summary:

A security researcher is a cybersecurity expert who identifies vulnerabilities, analyzes malware, and develops strategies to mitigate threats. Their work involves deep technical analysis, reverse engineering, and staying ahead of evolving cyber risks.

Security researcher key points:

• Role & responsibilities: Security researchers investigate vulnerabilities, analyze malware, and document threats to enhance cybersecurity defenses.
• Security research applications: Industries like national security, utilities, transportation, and healthcare rely on security research to prevent cyberattacks.
• Security researcher vs. analyst: Researchers focus on discovering vulnerabilities and developing defenses, while analysts monitor and respond to threats in real time.
• Security researcher vs. ethical Hacker: Ethical hackers test systems for weaknesses, while security researchers often work on broader vulnerability research and malware analysis.
• How to become one: A mix of education, hands-on experience, certifications, and continuous learning is essential for aspiring security researchers.

What is a security researcher?

Security researchers are skilled computer experts that use their technical knowledge to identify cybersecurity vulnerabilities within an organization or industry. A cybersecurity researcher must keep up with the latest data, developments, and trends in the cybersecurity world. Generally, they have responsibility for investigating malware, analyzing and understanding their capabilities, documenting the incidents of compromise (IOCs), and understanding the best steps for mitigation of the threat. They may also have highly specialized industry expertise.

Security researchers spent considerable time reviewing source code and malware and reviewing incident reports to understand threats better. Malware can present a difficult challenge. It takes patience and strong analytical skills to disassemble malware, reverse engineering it to know how it works, and design mitigations. The job of a security researcher is almost without scope as the variety, depth, and breadth of malware variants is massive. In addition, repacking and remanufacturing of existing malware has led to an almost exponential increase in malware. For this reason, security researchers must have a strategy to focus their efforts on the areas that will most likely reap benefits for their organization.

Examples of security research

Examples of security research are often focused on industry sectors. For instance, municipal utilities have already experienced attacks on network and operational technology systems. Serious flaws could result in the shutdown of critical infrastructures such as power generation, municipal water supplies, and more. Moreover, the number of attacks in the public domain continues to increase every year. 

Another area that has merited focused security research is the public transportation sector. Utilities such as railroads have been attacked by various cyberattackers, from criminal gangs to shadow organizations sponsored by malicious nation-states. Security research will identify and fix flaws in the internet of things (IoT) infrastructure, which is part of every modern railroad and commuter system. IoT is pervasive in communication systems and control systems within modern railroads.

Security research in medical devices has become a priority given the continued escalation in cyberattacks on healthcare institutions. In addition, recent news continues to report on massive breaches of patient records, especially as documented within the United States.

Difference between a security researcher and security analyst

The primary difference between a security researcher and a security analyst lies in their focus and responsibilities within the cybersecurity domain. 

A security researcher primarily concentrates on identifying, analyzing, and understanding vulnerabilities within systems and software, often engaging in activities such as malware analysis, source code reviews, and the development of new defensive tools and techniques. Their work is often proactive and research-oriented, aimed at advancing the understanding of security threats and improving protective measures.

In contrast, a cyber security analyst tends to focus on the operational aspect of cybersecurity, monitoring security systems for potential threats, responding to incidents, and conducting security assessments to ensure that existing measures are effective.

While both roles are crucial for safeguarding organizations against cyber threats, security researchers are more involved in exploration and innovation, whereas security analysts emphasize real-time defense and incident management.

Security researcher vs ethical hacker

The term “security researcher” is often used interchangeably with ethical hacker, white hat hacker, or hacker. These terms describe a cybersecurity professional who uses their skills to identify and address security vulnerabilities in computer systems, networks, or applications. Unlike malicious hackers (also known as black hat hackers or threat actors) who exploit vulnerabilities for unauthorized access or malicious purposes, ethical hackers work with the permission of the system owner to assess and improve security.

The primary goal of an ethical hacker is to proactively identify weaknesses in a system’s defenses before malicious actors can exploit them. Ethical hackers use various tools and techniques to simulate potential cyber attacks, assess vulnerabilities, and recommend security measures to strengthen the overall security posture of an organization. Their work helps organizations prevent data breaches, protect sensitive information, and ensure the integrity and availability of their systems. Ethical hacking is an essential component of proactive cybersecurity efforts to stay ahead of evolving threats in the digital landscape.

At Bugcrowd, we primarily use the phrase “hacker” to describe “the good guys.”

How to become a security researcher or security engineer

Becoming a cybersecurity researcher requires a blend of formal education, continuous learning, and practical experience in the field of cybersecurity. Aspiring researchers should focus on gaining a strong foundation in computer science or information security, coupled with an understanding of current threats or threat intelligence and vulnerabilities. This journey involves not only pursuing relevant academic qualifications but also actively engaging in hands-on projects, networking with professionals, and staying updated with the latest developments in malicious activities and defense mechanisms. Cultivating analytical skills and a curious mindset is essential, as security researchers must be able to scrutinize data, identify patterns, and communicate their findings effectively.

How to become a security researcher

• Earn a Relevant Degree: Pursue a Bachelor’s or Master’s degree in computer science, information technology, information security, or a related field to build foundational knowledge.
• Gain Practical Experience: Seek internships or entry-level positions in software companies or research labs to apply theoretical knowledge in real-world scenarios.
• Stay Updated: Continuously learn about the latest technologies, malware, and cybersecurity threats to remain effective in vulnerability research and defense strategies.
• Develop Analytical Skills: Cultivate strong analytical abilities and curiosity to dig deep when investigating anomalies or security concerns.
• Engage in Continuous Learning: Participate in workshops, conferences, and online courses to enhance your skills and knowledge in emerging cybersecurity trends.
• Network with Professionals: Connect with other security researchers and cybersecurity professionals to learn from their experiences and insights.
• Practice Reverse Engineering: Get hands-on experience in reverse engineering malware and software to understand their workings and potential vulnerabilities.
• Contribute to Open Source Projects: Join open-source cybersecurity projects to collaborate with other researchers and refine your skills.

Obtain Professional Certifications: Consider certifications focused on offensive operations, penetration testing, and malware analysis to validate your skills and knowledge.

Resources for security researchers

Security researchers play a critical role in the early identification, documenting, and reporting of vulnerabilities across many organizations and industries. Yet, the pool of security researchers that can be hired by anyone organization is often minimal.  Vulnerability disclosure programs and crowd-sourced penetration testing have provided an enhanced strategy for organizations to use today to leverage a broader set of security researcher resources.
