January 3, 2025

Organizations today are facing an overwhelming wave of cybercrime. The fast rate of digital transformation, growth of the Internet of Things (IoT), rapid increase of remote work, and poor cybersecurity practices have made organizations of all types vulnerable to cyberattacks. However, nothing puts an organization at risk of experiencing cybercrime more than the lack of in-house cybersecurity professionals, including cybersecurity engineers.

Have you ever asked yourself, “What is cybersecurity?” or “what is a cybersecurity engineer?” If so, you’ll find everything you need to know below.

What is a cybersecurity engineer? The definition

Cybersecurity engineers are IT professionals who defend organizations from intruders and the havoc they cause. As a cybersecurity engineer, you will help prevent data breaches by creating, implementing, and monitoring security systems and features. The security measures you will take and the solutions you will design, launch, and maintain prevent unauthorized users from accessing sensitive data, making cybersecurity engineers invaluable to organizations.

Roles and responsibilities of a cybersecurity engineer

Cybersecurity engineers have many duties that go beyond creating, implementing, and monitoring defensive security systems and features. Other tasks a cybersecurity engineer is responsible for include:

  • Configuring and installing firewalls and intrusion detection systems (IDS)
  • Promptly responding to data security crises
  • Overseeing any changes in facilities, software, hardware, user needs, and telecommunications
  • Performing penetration testing
  • Conducting network maintenance
  • Providing information assurance

Cybersecurity engineers also act as consultants within an organization and are responsible for suggesting specific modifications in any area that affects IT security. Some examples include technical, legal, and regulatory areas.

Essential skills and qualifications for a cybersecurity engineer

Succeeding in a cybersecurity engineering role isn’t possible without targeted skills and qualifications. The technical skills you’ll need as a cybersecurity engineer are related to:

  • TCP/IP, user datagram protocol (UDP), IP security (IPSec), HTTP, HTTPS, routing protocols and other network and web-related protocols
  • Phishing, advanced persistent threats (APT), and social engineering
  • Network access controllers (NAC)
  • Gateway anti-malware
  • Enhanced authentication

Also, although cybersecurity engineers are not ethical hackers, understanding the fundamentals of ethical hacking can help you effectively test the security solutions you create. This enables cybersecurity engineers to decrease the vulnerabilities of networks and computer systems.

Cybersecurity engineers also need soft skills, especially communication, analytical and problem-solving skills. However, cybersecurity engineers don’t come by these skills easily. These skills are gleaned through cybersecurity degrees, work experience, and cybersecurity certifications.

Most employers require cybersecurity engineers to have a bachelor’s degree in cybersecurity or a related field. Other acceptable subjects include computer science, mathematics, engineering, or information security. A master’s degree in an appropriate subject can open more job opportunities and unlock better salaries for cybersecurity professionals.

Job description and responsibilities

Not every employer writes the same job description for cybersecurity engineers. However, most job descriptions for these IT pros share commonalities. They often call for most or all the skills listed earlier.

A cybersecurity engineer’s job description also entails overseeing an organization’s most crucial digital systems and information technology (IT) infrastructure and working to protect key platforms, including critical applications, data storage, and networks that underpin all digital activity. If you’re applying for cybersecurity roles, including cybersecurity engineer jobs, don’t be discouraged if you don’t meet an employer’s educational requirements. Employers sometimes waive educational requirements for candidates with significant work experience and relevant IT skills and certifications.

For example, a cybersecurity engineering job description may call for a master’s degree. If you only have a bachelor’s degree, you should consider applying if you have several years of experience, cybersecurity certifications, and expertise in the field.

Career path and advancement

A cybersecurity engineer's career path and advancement can vary, but you can typically begin your cybersecurity career while earning a security-focused degree. It’s common to start out at the help desk as time allows and participate in a cybersecurity-related or cybersecurity engineering internship.

Once you’ve earned a suitable degree, worked an entry-level IT job, and completed an internship in cybersecurity, you’ll be ready to step into your first full-time job role. Common roles for future cybersecurity engineers include penetration tester, cybersecurity analyst, and cybersecurity architect.

To secure a job as a cybersecurity engineer, you’ll typically need at least 3 years of experience in an entry-level IT job role. Once you have your education, work and internship experience, and cybersecurity certifications, you can start applying for cybersecurity engineer jobs.
