What Is Cybersecurity?
Definition and importance of cybersecurity
Cybersecurity is the practice of protecting networks, computer systems, and sensitive data from unauthorized digital access. It is essential for organizations to protect themselves from cyber threats and data breaches. Cybersecurity professionals play a crucial role in safeguarding information and preventing cyber attacks for everyone from small companies to global organizations.
Brief history and evolution of cybersecurity
From the early days of the ARAPANET in the 1970s, the first commercial antivirus software in the 1980s, to bringing the world online in the 1990s, threats have become more diverse and common. As a result, there is a need to create advanced threat detection systems and more robust cybersecurity measures for computer systems and beyond.
Current state of the cybersecurity industry
According to Statista, the global cybersecurity industry is expected to exceed $271 billion by 2029, which means more opportunity and demand for many cybersecurity professionals. So what drives this growth? Global cyber threats continue to evolve, hacking attempts happen daily, new technologies emerge, and the digital transformation, the process in which companies incorporate digital technologies. As companies grow, there is an increasing need for advanced computer security and measures across digital platforms to protect sensitive information, data and infrastructure.
Benefits of a Cybersecurity Career
Job market demand and growth prospects
Cybersecurity careers can offer excellent job security and growth prospects. Statista notes that as of 2023, the average number of cybersecurity roles in the U.S. were around 750,000 with the largest number of openings in California and Texas.
The demand for global cybersecurity jobs is on the rise. According to a 2023 report from (ISC)², a leading global cybersecurity certification organization, it's estimated that there may be a global cybersecurity workforce gap of around 4 million unfilled jobs, underscoring the severe shortage of skilled professionals in cybersecurity careers.
As a result of the global shortage in the cybersecurity field, some roles may require more specialized cybersecurity skills such as:
- Cloud security
- Incident response
- Penetration testing and ethical hacking
- Threat intelligence
