How to become a cyber security engineer
What is a cyber security engineer?
Cyber security engineers play a vital role in protecting computer and networking systems from potential hackers and cyber attacks. They design security infrastructure, identify potential threats and work to fix vulnerabilities to protect the systems.
Technology evolves rapidly, and as security gaps in technology have become more sophisticated, demand for information security occupations has increased, too. This guide outlines the necessary education, certifications and skills to become a successful cyber security engineer (as well as how much they may be able to earn).
Types of cyber security engineers
Cyber security is a broad topic, so there are plenty of more specialized opportunities within the field. Here are some of the different types of cyber security engineers who focus on specific elements of cyber security:
Application Security Engineer: These engineers identify and address security weaknesses in applications that a business develops or uses. They implement controls, including app authentication, encryption, and authorization settings, test software, set up firewalls and scan/test applications.
Network Security Engineer: Network security engineers are responsible for maintaining the safety of a business' organizational network. They monitor the network for breaches, identify vulnerabilities and develop solutions and safeguards to protect the network against attacks.
Cloud Security Engineer: A cloud security engineer is responsible for defending a business against attacks within the cloud. The engineer is responsible for configuring the network security, building applications, identifying and addressing vulnerabilities and maintaining a secure cloud infrastructure.
According to a study by (ISC)², a nonprofit of cybersecurity professionals, the global cyber security workforce consists of approximately 4.7 million professionals, which is an all-time high. However, the study also revealed that 3.4 million more cybersecurity professionals are needed to meet the increased demand and effectively protect assets. Since businesses are increasingly relying on networks, the cloud and applications, there is significant demand for all of these types of engineers.
Cyber threats faced by information security engineers
Cyber security engineers need to be prepared to defend a business against multiple types of cyber threats. Rich Selvidge, President of SecureTrust, explains that malware, phishing, DDoS attacks, data breaches, insider threats and targeted attacks by cybercriminals are some of the most common types of threats.
Artificial intelligence and machine learning are rapidly growing in popularity, but also pose new threats including unauthorized actions, data manipulation and potential vulnerabilities from bad AI outputs.
The cyber security landscape also faces emerging threats and trends. Artificial intelligence and machine learning are rapidly growing in popularity, but also pose new threats including unauthorized actions, data manipulation and potential vulnerabilities from bad AI outputs.
The increased reliance on cloud data storage makes the cloud an attractive target for hackers. Selvidge notes that IoT botnets, cloud misconfigurations and vulnerabilities in new technologies are also concerns, and privacy regulations like GDPR and CCPA impact security strategies.
What does a cyber security engineer do?
Cyber security engineers work closely with other IT professionals to ensure comprehensive security solutions. They may collaborate with IT teams on new software and app development, network improvements, and cloud-based systems implementation and monitoring, ensuring that these systems are as secure as possible. Additionally, engineers often collaborate across multiple departments, consulting with department supervisors about technology and security needs. Engineers may report to upper-level management and stakeholders, and may create reports and recommendations for management to review and approve.
Typical job duties
During the course of a day, cyber security engineers may have multiple job duties and responsibilities:
- Design and implement security measures:
- A cyber security engineer is responsible for designing and implementing security measures to help prevent breaches and prevent problems before they occur. Depending on the engineer's role, they might be responsible for an organization's network, applications, cloud storage or all of those elements.
- Perform risk assessments:
- Regularly performing risk assessments and penetration testing allows a cyber security engineer to continuously evaluate and monitor the security measures that they have implemented. That testing helps an engineer to evaluate a system's overall security before breach or problem has occurred, so if the engineer finds weaknesses, they can take steps to fix those issues and keep the organization's system and data well-protected.
- Troubleshoot problems:
- If a cyber security engineer identifies vulnerabilities or security issues, they need to take the appropriate steps to troubleshoot those issues. That might involve identifying several remedies, proposing those solutions or identifying the best solution, and implementing a fix to address the vulnerability.
- Conduct security audits:
- Cyber security engineers may also perform security audits, during which they conduct a thorough assessment of an organization's information systems, records and activities. During the audit, the engineer will look for appropriate system controls and evaluate the security policy and procedures. Based on the audit's results, the engineer will make recommendations for improvements to heighten the organization's security, and once approved, may implement those improvements.
- Respond to security breaches:
- If security breaches do occur, a cyber security engineer needs to promptly identify and respond to the breaches. The engineer will take steps to immediately secure the company's data, then evaluate the extent of the breach. They will work to identify why the breach occurred and implement protections to prevent future breaches.
During their work, cyber security engineers also need to be aware of the many ethical and legal considerations involved in cyber security engineering. According to Future of Tech, a few of the unique ethical issues that cyber security engineers face include:
How to appropriately and sensitively handle sensitive personal, private or proprietary information, and how to keep that information confidential.
How to implement security measures to protect the privacy of others, such as when a company collects personal data about clients and then becomes responsible for protecting the data.
Additionally, cyber security engineers need to ensure that their organization stays in compliance with regulations like GDPR and CCPA. According to Securiti, these regulations help to ensure data privacy and protection, and they instituted strict standards such as requiring businesses to inform users when their data is being collected and requiring businesses to haw a lawful basis for processing customer data. Cyber security engineers need to consider compliance and work with Data Protection Officers to implement applicable regulations when designing processes and installing appropriate security protections.
Education and training
There are several different educational and training paths that you might take to become a cyber security engineer.
Associate degrees
An associate degree in cyber security provides you with knowledge about basic cyber security issues, computer programming languages and ethics in cyber security. You can complete an associate degree in just two years, and earning your associate degree requires less of a financial investment than longer degree programs. Keep in mind that an associate degree may qualify you for an entry-level position, but you will likely need additional education if you want to pursue more advanced career opportunities.
Bachelor's degrees
It's fairly common for employers to look for a security engineer who has at least a bachelor's degree in cyber security or computer science.

- Critical thinking: Cyber security engineers need to be able to think critically, including asking thoughtful questions, evaluating data and identifying and assessing solutions.
- Communication skills: Written and verbal communication skills are important in most cyber security roles. Most importantly, an engineer needs to not only be able to communicate with IT professionals, but to also explain complex and technical topics to staff members who don't have an IT background.
- Collaboration talents: An engineer needs to be able to work with an IT team and to collaborate with other organization members, including supervisors and potentially public relations professionals.
While it's helpful to naturally have some of these soft skills, you can develop many of these soft and technical skills through education, training and on-the-job experience. "Internships and work experience are extremely valuable when starting out as a cybersecurity engineer," says Selvidge. "These provide hands-on experience and allow you to apply classroom knowledge."
Perhaps most importantly, cyber security engineers need to continue to learn about new industry advancements. "Ongoing training is essential, as threats and technologies continuously evolve," Selvidge says. "Attending security conferences, taking new courses and participating in capture the flag competitions help you to stay current." Capture the flag competitions challenge teams of individuals to find text strings hidden in vulnerable websites or software, honing their skills. Pursuing this and other continuing education and professional development opportunities will help an engineer to stay aware of new threats, new protections and new best practices, helping them to better protect their organizations.
Tools and technologies
Cyber security engineers use several common tools and technologies to perform their work:
Firewalls function as a barrier between an internal network and the public internet. They monitor and filter network traffic and can be customized with an organization's security policies to ensure maximum protection.
Vulnerability scanners automatically scan an organization's networks, hardware, software and systems. Thes scanners look for potential risks and vulnerabilities, like misconfigurations, patching issues and risky ports.
Intrusion detection systems (IDS) and intrusion prevention systems (IPS) monitor a network constantly. They help to identify potential security incidents, stop the incidents and record information about each incident that an engineer can then review and address.
Penetration testing tools simulate cyberattacks in an attempt to breach an organization's digital systems. These tools help to identify and test vulnerabilities so that an engineer can address those vulnerabilities before an attack occurs.
Security Information and Event Management (SIEM) tools analyze applications and network hardware to provide real-time security alerts, allowing an engineer to promptly implement threat remediation.
What is the median salary of a cybersecurity engineer?
According to the Bureau of Labor Statistics (BLS), the median annual wage for cyber security engineers (called information security analysts by the BLS) is $112,000. Income can vary depending on industry, too. Engineers in the information industry earned a median wage of $165,110, while those in scientific research and development earned $136,810. Engineers in computer systems design earned $122,430.
The BLS projects that employment of cyber security engineers should grow by 31.5% through 2032. Approximately 19,500 openings are projected to become available each year, which is much faster growth than what is average across all occupations. That growth is due to increasing demand for security engineers, which is prompted by the growth of cyber attacks and an increased focus on cyber security. The growth in digital health services also means increased data security risks and a growing need for cyber security engineers.
