In today’s hyper-connected digital world, cyber threats are more prevalent than ever, with cyberattacks occurring every 39 seconds on average, according to a study by the University of Maryland. With such staggering statistics, the need for robust cybersecurity measures has never been more urgent. But what exactly does cybersecurity entail?
Cybersecurity, as defined by the dictionary, refers to the practice of safeguarding electronic data against criminal or unauthorized use, along with the measures implemented to achieve this protection.
Join us as we explore the dynamic world of cybersecurity and its various dimensions, and the strategies employed to combat ever-evolving threats.
What is Cybersecurity?
To clarify, cybersecurity is a subset of IT security with other components like physical security and information security.
While all squares are rectangles due to their shared characteristic of having four right angles, not all rectangles are squares because squares must also have equal side lengths. Similarly, while all cybersecurity measures fall under the umbrella of IT security, not all IT security measures qualify as cybersecurity.
According to CompTIA’s Chief Technology Evangelist, James Stanger, cybersecurity specifically focuses on safeguarding electronic assets, including internet, WAN, and LAN resources, utilized for storing and transmitting information.
These electronic assets are targeted by hackers with malicious intent, seeking to exploit vulnerabilities and steal proprietary data through data breaches.
Why Is Cybersecurity Important?
The cybersecurity market is anticipated to grow to $300 billion by 2024. In a world where our lives are intertwined with technology, the buzz about cybersecurity isn’t just another tech jargon.
