What is a cybersecurity engineer?

A cybersecurity engineer is a “digital fortress builder” entrusted with the blueprints and keys to safeguard an organization’s critical infrastructure and assets from emerging threats. 

Their main duties revolve around designing and improving security infrastructure around an organization's unique environment. This includes the monitoring and customization of firewalls, VPNs, or intrusion detection/prevention systems (IDS/IPS) to build barriers against malicious cyber attacks.

 A cybersecurity engineer is also involved in:

• Incident response (IR) and recovery: Employing their expertise in network traffic analysis, cybersecurity engineers respond to incidents, investigate the root cause by (conducting forensic analysis and isolating affected systems), and remediate to restore normalcy. 

• Compliance and risk management (RM): Ensuring alignment with regulations and standards like the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), or The National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF). Cybersecurity engineers evaluate potential risks and implement measures to mitigate them. This involves continuously assessing security policies and controls and adjusting strategies to meet evolving compliance requirements.

• Vendor management and procurement: Working with external vendors, cybersecurity engineers evaluate and select the right security products and services. This involves negotiating contracts, ensuring the products align with the organization's security needs, and managing ongoing vendor relationships.

• Disaster recovery (DR) planning: Crafting and maintaining a DR plan ensures the organization is prepared to respond to any catastrophic event. This includes defining and regularly testing procedures (with tools such as tabletop exercises) to restore systems and data after a significant failure or attack.

Cybersecurity analyst vs. cybersecurity engineer

A cybersecurity engineer's responsibilities can overlap with a cybersecurity analyst's. So understanding each role's distinct functions is key to selecting your career path. 

Think of the analyst as the “security sentinel” patrolling the castle grounds, watching for any signs of trouble. On the other hand, the engineer is the “builder” or “architect”. He constructs the “castle's” defenses. And fortifies it against potential threats whilst ensuring it remains accessible to everyday residents.

 

The responsibilities of an analyst or engineer will often vary depending on the organization they work for and their seniority. So it's difficult to nail down exactly what an “analyst” or “engineer” would usually do (as I don’t really think there is or should be a “usual”).

Unfortunately, many cybersecurity engineer roles aren't entry-level, requiring at least a couple of years of IT experience.

I'm sharing this not to discourage you but to be honest and transparent. I want you to succeed, but you likely won't start as a cybersecurity engineer without prior experience. It's not impossible, but it's definitely not the industry norm right now.

The good news is that you can pivot from any IT background into a cybersecurity engineer position as long as you diligently work on your skill set. For this reason, I advise pursuing entry-level IT/cybersecurity positions as you build toward the cybersecurity engineer skill level. 

Remember, paid experience often matters more than training, certifications, and degrees combined. So seize the first paid opportunity you can find!

Here's more encouraging news: a college degree isn't a must-have. Even if a job posting mentions a degree, consider it a "nice to have," not a requirement. 

While a degree might give you an edge among applicants, don't be deterred if you lack one. Your unique skills and experience can still make you a standout candidate in any cybersecurity role.
