What does a cybersecurity engineer do?

While a vitally important role within any organization, it can oftentimes be unclear for the uninitiated to answer the simple question “what does a cybersecurity engineer do?” The title of cybersecurity engineer — sometimes called an information security engineer, data security engineer, or web security engineer — is someone who comes up with ways to protect devices, services, and networks from malicious digital attacks. A cybersecurity engineer also designs and implements secure networks and ensures that the network and its attendant resources (databases, printers, smartphones, etc.) are protected from cyber-attacks. 

The security engineer also regularly tests and monitors the security systems to ensure they are up to date and functioning properly. Organizations and/or individuals hire these engineers to help protect organizational data, sensitive and confidential information, financial/transactional information, and the reputation of the organization as a whole. To this end, they primarily protect data from data breaches. 

Responsibilities of a cybersecurity engineer

The responsibilities of a cybersecurity engineer have a lot of overlap with cybersecurity analysts, who are also tasked with protecting sensitive information. The duties of those in the role of cybersecurity engineering include: 

  • Planning, implementing, managing, monitoring, and upgrading security measures and infrastructure to protect organizational data and resources
  • Making sure adequate security measures and protocols are in place to secure organizational data
  • Troubleshooting network and security issues
  • Testing and identifying network and system vulnerabilities
  • Responding to security breaches with their SOC team comprised of cybersecurity analysts, pen testers, security consultants, cyber threat analysts, and sometimes compliance analysts.
  • Liaising with the appropriate departments of the organization in the course of security duties
  • Administrative duties and report writing

Job opportunities for a cybersecurity engineer 

As mentioned earlier, the big headlines about governmental and private data breaches have caught the attention of leaders and business owners across the globe.

According to statistics from the US Bureau of Labor, job opportunities in cybersecurity are projected to grow by 31% between 2019 and 2029, with unemployment in the field is nearly zero. Spending on cybersecurity is also projected to reach $6 trillion annually in 2021. 

These roles are going to be right in line for people with cybersecurity engineering skills.

Cybersecurity engineers can work as network security engineers, IT security engineers, security analysts, penetration testers, information assurance engineers, and information systems security engineers, to mention a few. All of these jobs are high-paying, future-proof careers, too.

The mean salary for security analysts nationally is ~$100k. For pen testers, that number is ~116k

Required skills of a security engineer

Cybersecurity jobs are skill-intensive. They require a high degree of training and experience to get into. As such, most organizations require at least a bachelor’s degree in cybersecurity, computer science, or a related field. Some employers give preference to applicants with a master’s degree.

A cyber or CS degree is just the starting point, though. A cybersecurity engineer requires several hard/analytical and soft skills to succeed in the field.

This includes routing protocols, subnetting, Voice over IP(VoIP), DNS, encryption techniques and technologies, Virtual Private Networks (VPN), and secure network architectures. You also need to know about network security technologies like firewalls and encryption. 

Database platforms:

Cybersecurity concerns itself with the protection of data. Therefore cyber engineers need extensive knowledge about how data is structured, stored, and disseminated will surely help in that task. 

Knowledge of operating systems: 

Software systems typically run on operating systems, with each having its own vulnerabilities and idiosyncrasies. Familiarity with the operating systems you’re analyzing is crucial for diagnosing the problem. 

The soft skills you need to become a cybersecurity engineer

In addition to the hard skills mentioned above, a security engineer needs soft skills to carry out the job well. The major ones the engineer needs are: 

Communication skills 

Security engineers often need to explain complex ideas simply. Their audiences are often laymen who have no experience or knowledge of the cybersecurity field. Though analysts are more likely to liaise with other departments, engineers are sometimes tasked with interdepartmental comms.

Problem-solving skills 

Ingenuity in the response of the security engineer to breaches and attacks are an advantage. 

Learning capacity

Cybersecurity engineers often read up on trends and vulnerabilities so they can quickly adapt and apply those skills against new threats. 

While hard skills are vital, employers hire cybersecurity engineers that showcase both hard and soft skills. These soft skills are referred to as risk-mitigating factors, making them essential for any security engineer.
