What is cybersecurity?

Cybersecurity (sometimes called computer security or information security) is the practice of protecting computers and networks from theft, damage, or unauthorized access.

As our interconnectivity increases, so do the opportunities for bad actors to steal, damage, or disrupt. A rise in cybercrime has fueled a demand for cybersecurity professionals. Job outlook is expected to grow by more than 30 percent between 2019 and 2029 [1].

How to choose a cybersecurity certification

Earning a certification in cybersecurity can validate your hard-earned skills and help you advance your career. Here are some things to consider when choosing which certification is right for you.

  • Your level of experience: Start with a certification that matches your current skill set. Invest in a certification you know you can achieve, and use it to advance toward more challenging certifications later in your career.

  • Cost: Getting certified typically costs several hundred dollars (or more), plus the additional fees to maintain it. The right certification can open up better job prospects or higher salaries, but it’s important to invest wisely.

Tip: Some universities and employers will help pay for your certification, so it’s always a good idea to ask first.

  • Area of focus: If you’re just getting started in cybersecurity or want to move into a managerial role, a more general certification might be a good choice. As you advance in your career, you might decide to specialize. A certification in your concentration area can validate your skills to potential employers.

  • Potential employers: Check some job listings of employers you may want to work for (or job titles you plan to apply for) to see what certifications are commonly required.

How to get into cybersecurity: First steps

Many of the most coveted certifications require (or at least recommend) some previous experience in cybersecurity or IT. If your career goals include a job in this in-demand industry, there are some steps you can take now to start gaining the experience you need.

Get a degree in computer science.

While you don’t need a degree to enjoy a successful career in cybersecurity, it can help you build a strong foundation. Many of the most prestigious certifications will waive some of the work experience requirements if you’ve earned a bachelor’s or master’s degree in computer science or a related field. 

The University of Pennsylvania offers an Ivy League Master of Computer and Information Technology degree designed especially for students without a computer science background. Try a course before you apply to see if this program is a good fit.

Start with an entry-level job in IT. 

Hands-on experience is often the most effective way to prepare for certification exams. Start accumulating work experience with an entry-level role as a cybersecurity analyst. Many cybersecurity professionals start off in more general IT roles

Get an entry-level IT certification.

Enhance your resume and make yourself more attractive to hiring managers with a certification that doesn’t require previous experience.

Entry-level IT certification options include lower-level credentials from some of the companies listed above. You can also build job-ready skills with no previous experience with the Google IT Support Professional Certificate and IBM Cybersecurity Analyst Professional Certificate through Coursera.
