The year 2017 marked another milestone for information security: more breaches, bigger losses, more coverage and more jobs and opportunities for IT and programming professionals. By the end of 2017, according to a Cyber Seek report the number of cybersecurity job openings in the USA stands at just over 285,000. Projections continue to be robust further out: CSO expects that number to hit 500,000 by 2021, with more than 3 million cybersecurity jobs open for the rest of the world that same year.

When evaluating prospective InfoSec candidates, employers frequently look to certification as an important measure of excellence and commitment to quality. We examined five InfoSec certifications we consider to be leaders in the field of information security today:

  1. CEH: Certified Ethical Hacker
  2. CISM: Certified Information Security Manager
  3. CompTIA Security+
  4. CISSP: Certified Information Systems Security Professional
  5. GSEC: SANS GIAC Security Essentials

This year's list includes entry-level credentials, such as Security+ and GIAC Security Essentials, as well as more advanced certifications, such as the CEH, CISSP and CISM. We also offer some additional certification options in the last section that covers choices outside our top five, because the field of information security is both wide and varied, with lots of other options.

Security-related job roles cover a lot of ground, such as information security specialist, security analyst, network security administrator, system administrator (with security as a responsibility) and security engineer, as well as specialized roles such as malware engineer, intrusion analyst and penetration tester. Average salaries for information security specialists and security engineers – two of the most common job roles – vary widely depending on the source. For example, Simply Hired reports $124,000 for specialist positions, whereas Glassdoor's national average is just under $78,000. For security engineers, Simply Hired reports $96,000, with Glassdoor's average at $86,000.

If you're serious about advancing your career in the IT field and are interested in specializing in security, certification is a great choice. It's an effective way to validate your skills and show a current or prospective employer that you're qualified and properly trained.

Before examining the details of the top five InfoSec certifications, check the results of our informal job board survey. The data indicates the number of job posts nationwide in which our featured certifications were mentioned on a given day. The data should give you an idea of the relative popularity of each certification.

CEH (EC-Council)
























Security+ (CompTIA)







Hackers are innovators and constantly find new ways to attack information systems and exploit system vulnerabilities. Savvy businesses proactively protect their information systems by engaging the services and expertise of IT professionals skilled in beating hackers at their own game (often called "white hat hackers" or simply "white hats"). Such professionals use the very skills and techniques hackers themselves use to identify system vulnerabilities and access points for penetration to prevent hackers' unwanted access to network and information systems.

The Certified Ethical Hacker (CEH) is an intermediate-level credential offered by the International Council of E-Commerce Consultants (EC-Council). It's a must-have for IT professionals pursuing careers in ethical hacking. CEH credential holders possess skills and knowledge on hacking practices in areas such as footprinting and reconnaissance, scanning networks, enumeration, system hacking, Trojans, worms and viruses, sniffers, denial-of-service attacks, social engineering, session hijacking, hacking web servers, wireless networks and web applications, SQL injection, cryptography, penetration testing, evading IDS, firewalls, and honeypots.

To obtain the CEH certification, candidates must pass one exam. A comprehensive five-day CEH training course is recommended, with the exam presented at the end of training. Candidates may self-study for the exam but must submit documentation of at least two years of work experience in information security with employer verification. Self-study candidates are required to pay an additional $100 application fee. Education may be substituted for experience, but this is approved on a case-by-case basis.

Because technology in the field of hacking changes almost daily, CEH credential holders are required to obtain 120 continuing education credits for each three-year cycle.
