Let’s Talk About Certs, Baby

There’s more than one path into the high-demand, high-reward career field of cybersecurity. Not everyone can afford the time and cost of a traditional college education and it is not always necessary to get your foot in the door.


An alternative is to use low-cost resources to make a plan for self-study, get certifications, and create a portfolio to showcase to potential employers.


Start With the ABCs

CompTIA A+ (parts 1 and 2), Network+, and Security+. Go ahead and get yourself some basic training in Linux too.


Let’s clear something up. IT is not Cybersecurity, BUT basic knowledge about how computers work, how to use the command line, differences between Windows and Linux operating systems, and how computers communicate over the network is necessary in order to understand cybersecurity concepts like security controls, application security, vulnerability management, configuration controls, network access controls, identity and access management, and more.


With these basics under your belt you could easily qualify for a job in an entry-level IT help desk position. You don’t have to work in IT to work in cybersecurity, but it certainly doesn’t hurt. If you are ready to get your hands dirty, go for it! You will gain experience and make contacts that will help you as you continue your journey into cybersecurity.


Network, Network, Network!

Make new friends, but keep the old. Start connecting with people who work in the field and do what you aspire to do. LinkedIn is your best asset when it comes to networking and showcasing your new skills and certifications. Pro tip: Try searching for groups that align with your interests, and then interact with the folks in those groups.


Join professional associations if you can afford the membership fees, and attend conferences when you are able. Some are virtual, and some are free or low cost. Immerse yourself in the infosec culture, soak up the news, get advice, and find new resources for learning. You have to be active. Commenting, posting, and engaging will get you noticed. And don’t be afraid to connect with people!


Research & Consider Various Roles in the Field

The cybersecurity field is vast and varied. No one person working in cybersecurity knows everything. Once you’ve achieved the ABCs, it's time to figure out what role you want to play in this new world.


A great place to start learning about cybersecurity roles is the NICE Framework.


Align Career Goals With Additional Certifications to Focus Your Path

Now that you know where you want to end up, what is the best path to get there?


CompTIA offers affordable, well-respected certifications in IT and cybersecurity and it is a great place to start. Their training programs are also affordable and you can find alternative training elsewhere, like LinkedIn Learning, YouTube, and Udemy. Start with the basics and progress to more advanced certifications. Check out the CompTIA Cybersecurity Career Pathway.


IBM offers a comprehensive training program for the IBM Cybersecurity Analyst Professional Certificate that is also affordable and valued by employers. The courses can also transfer for college credit, if you choose. There are 8 courses in the program, taught by IBM Security Learning Services on Coursera. You get a 7-day free trial and then it’s $49 a month.


Create a Portfolio

Find ways to showcase your new skills to potential employers: Badges/certificates earned from CTF games, course completion certificates, a home lab project, a cloud lab project, endorsements from contacts. LinkedIn is a great place to share your accomplishments. You can also set up a personal website to showcase labs and other projects you’ve done.
