What Is A Security Engineer?
The internet is a fantastic thing. Only a few times in history has there ever been a technological innovation that revolutionized virtually every aspect of human life as the internet has.
Nowadays, human beings depend on the internet for nearly everything. However, this reliance on the internet and computers brings severe risks and security threats if these systems are not secured.
These risks are exacerbated by the growth and expanded use of "smart" devices and the Internet of Things, such as Smart TVs, Smart Fridges, etc.
But that's where Security Engineers come in.
Security engineering (or cybersecurity engineering) is the discipline of engineering focused on developing secure technical systems. Security engineering is also focused on designing systems resilient to other potential causes of outages, such as natural disasters.
Hackers and other nefarious agents are always poking holes in networks, looking for any possible exploit they can use to their advantage. These cyber-attacks can come in many different forms, such as phishing, malware, ransomware, DDoS attacks, etc.
It is the job of security engineers to prevent these attacks from being successful.
What Does a Security Engineer Do?
The cybersecurity profession is a broad one. Security engineers, as a result, will likely have many different job duties in their roles.
The exact duties will also differ depending on what kind of company they are working at. For instance, a FinTech company will undoubtedly have different security needs from a social media platform.
No matter what, though, as we mentioned, security engineers develop security tools, security protocols and systems and keep computer networks secure and running.

- Conduct investigations to identify new harmful behaviors, enforce product policies, and analyze distribution trends,
- Collaborate with cross-functional groups such as Engineering, Policy, and Legal to update policies, fix product loopholes, and provide users with a better user experience.
What Are The Security Engineer Job Qualifications?
In most cases, hiring managers will want security engineering candidates with at least a bachelor's degree in computer science, engineering, or another technical field.
Beyond that, security engineers may be expected to have some of the following qualifications:
- Knowledge of security protocols, methods and procedures,
- Experience in vulnerability testing and code-level security auditing,
- The capability to assess the security ramifications of system changes,
- Up-to-date understanding of recent cybersecurity trends, especially emerging threats or innovative hacking techniques,
- Command of programming languages such as Java, Python Net, C++, and others,
- The ability to read assembly and read obfuscated code,
- The ability to reverse engineer software systems,
- Experience with static and dynamic analysis of malicious binaries.
- The ability to collaborate with cross-functional teams.
What Are the Top Security Engineer Skills?
Considering these various job duties expected of security engineers, they must have several different technical and soft skills. The most important of which are:
Security Engineer Technical Skills
Given how much cybersecurity, as a field, has to do with network security, security engineers will certainly need extensive networking skills. Most of an organization's vulnerabilities and security threats lie in its network, after all.
Security engineering requires routing protocols, encryption, firewalls, and virtual private networks (VPNs).
Security engineers will need to think like hackers when securing a company's computer systems. For example, suppose potential vulnerabilities of exploits exist in a computer system. In that case, a security engineer will need to find them before anyone else does.
They can do so with penetration testing, also known as "ethical hacking." This involves a simulated cyber-attack by the security engineer to test a system's security and integrity.
Knowledge of Operating Systems
Security engineers will likely be tasked with securing computer systems running on several different operating systems. Therefore, they will need experience and knowledge of operating systems such as Windows, MacOS, or Linux.
Computer Hacking Techniques
As we've mentioned, cybersecurity is a rapidly evolving field. Likewise, as computing technologies themselves evolve, so do their potential vulnerabilities and security threats.
Security engineers must keep up with the latest trends in cybersecurity, security tools and the newest hacking techniques.
Security engineers will likely work alongside security analysts to monitor network activity on an Intrusion Detection System or IDS. Therefore, they must have intrusion detection and prevention skills for success in their roles.
Working With Databases
Often, when a hacker attempts to infiltrate or exploit a network, they're after the system's data. Whether that means passwords or credit card numbers, most companies are sitting on large amounts of valuable and sensitive data they need to protect.
Therefore, security engineers need to have experience with working with databases and large data sets if they are to protect them adequately.
Security Engineer Soft Skills
While security engineering is undoubtedly a very technical role, security engineers still need several soft skills for their day-to-day responsibilities.
Specifically, they need communication and cross-functional collaboration skills. Security engineers will rarely work along and will likely be part of a larger security team.
Security engineers will also need to be able to communicate with other stakeholders about security concerns, findings, or recommendations. Along these lines, they will need to share what are often complex cybersecurity details with both technical and non-technical stakeholders.
What Is The Difference Between A Security Engineer and A Security Analyst?
You may find two similar roles within the security team at some companies. This is, of course, a security engineer and security analyst.
Despite the similarity of the titles, these are distinct positions that come with different responsibilities.
Cybersecurity engineers are responsible for always investigating how nefarious actors can infiltrate an organization's networks and systems.
On the other hand, security analysts must work alongside other stakeholders at the company to assess and evaluate the cybersecurity needs and shortcomings within an organization's systems and networks.
How to Become a Security Engineer
First and foremost, if you want to become a security engineer, you'll need to first develop knowledge of and gain experience in computer science and network security, primarily.
Given how vital cybersecurity is for organizations, the level of knowledge necessary for the role will likely take years to acquire.
Don't feel discouraged if you can't find a security engineer position early in your engineering career. It typically takes years for software engineer to work their way up.
However, to do so, you'll need to follow these steps:
Earn a Bachelor's Degree
Unlike some other tech roles, hiring managers may require cybersecurity candidates to have a bachelor's degree. These degrees could be computer science, cybersecurity, engineering, or information technology.
Nevertheless, it is still possible to become a security engineer without a technical degree if you have extensive practical experience.
Not only that, in many cases, security engineers enter their roles after having worked as software engineers for several years. So, don't sweat it too much if you're currently an engineer without a degree.
Gain Experience with Information Technology
Now, this step is a must. You cannot become a security engineer without gaining extensive experience with information technology.
While it's true that many security engineers were once software engineers, many others start their careers from entry-level IT positions.
Some cybersecurity professionals work their way up from database administrators, systems administrators, IT support reps, or network engineers.
It's not uncommon for these individuals to work for several years in these positions, gaining the necessary experience.
If you want to become an information security engineer, we recommend that you first get one of these or other IT jobs if you have not already.
