Frequently asked questions about cybersecurity courses at Flatiron School

In addition to our free introductory cybersecurity workshops, Flatiron School specializes in flagship career-change courses. Our immersive Cybersecurity Engineering course is offered for anyone looking to start a career in cybersecurity.

What does cybersecurity do?

In simple terms, cybersecurity is the practice of securing networks, resources, and systems from digital/cyberattacks. This means that any time you take measures to protect a system or network from cyberattacks, that is cybersecurity. 

Despite its superficial simplicity, cybersecurity is a lot more complex than installing antivirus or antispyware software onto your machines. It is a wide, comprehensive field consisting of different disciplines and best practices to preserve the safety, integrity, and reliability of networks and digital systems.

On a professional level, pen testerscybersecurity analystscompliance analystscyber threat analystscyber consultants, and others work together every day to protect businesses and individuals from malicious cyberattacks.

Does cybersecurity require coding?

Familiarity with and understanding of cyber-adjacent programming helps cybersecurity professionals analyze software to discover security vulnerabilities and codes.

In other words, knowing how to code makes cyber experts better at their jobs.

But different cyber roles require different skills, and, likewise, different roles rely more on programming than others. If you're an analyst, you're much less dependent on programming than if you are, say, an engineer.

If you're an engineer, the language you'd want to focus on further depends on what type of engineer you are. Some engineers focus on computer forensics while others focus more on web apps or network security.

Python, JavaScript, Golang, C, and others are all important for cyber experts in more technical roles.

If you're looking to enter the cybersecurity industry, learn more about the best cybersecurity programming languages to learn.

Does cybersecurity require math?

Cybersecurity requires a basic understanding of cyber math fundamentals, but most of the math you'd do in a cyber job is done automatically by computers — especially in cryptography.

There are, however, still a few industries or areas of cyber that will deal in manual cryptography.

Is learning cybersecurity hard?

Just like with any tech career, cybersecurity requires a strong mix of technical and soft skills.

On the technical side, cybersecurity professionals need to understand the intricacies of risk assessment and management, authentication, Linux, information systems, digital forensics, and some cybersecurity coding languages.

As far as the soft skills you need for cybersecurity goes, communication, presentation skills, management skills, problem-solving, and many others are important. It's often overlooked how much cybersecurity experts work together as a team — SOC teams are at the heart of almost any successful cybersecurity response.

Why is it important to learn about cybersecurity?

In only about 20 years, the world has been flipped upside down from an analog to a digital world. Nearly everything we do is, in some way, connected to the internet. And while there are lots of benefits to this, there are undoubtedly a lot of vulnerabilities that come along with it.

With all of the devices we use every day come passwords, credit card information, health information, PIN numbers, documents, and more — any of which, if stolen, could mean a lot of trouble for our safety and security.

LIkewise, with all of this vulnerability comes responsibility. It's not important for all of us to be professional cybersecurity experts, but it is definitely important for all of us to understand how vulnerable our information and data are, and to take steps to protect them.

Can a non-IT person learn cybersecurity?

Many skills used in other technical roles are transferrable to cybersecurity, though you might need to dust off or acquire some skills as you break into the industry, like your familiarity with security ops or information systems.

In fact, if you're looking to break into the cybersecurity field, moving from another technical role is one of the best places to start. Most of them tend to value skills and professional certifications over a degree. Some of the most relevant skills are knowledge of basic and advanced cybersecurity concepts and strong non-technical/soft skills.

Learn more about the hard and soft skills you need to join the cybersecurity industry from another technical field.

What kind of jobs could I get after completing the Cybersecurity Engineering program?

Our Cybersecurity Engineering program teaches the skills to succeed in roles such as entry-level Security Engineer, Security Analyst, and Security Consultant. Check out our Cybersecurity Engineering bootcamp for more details!
