3. Cyber Security

Introduction(What is Cybersecurity?)

Computer securitycybersecurity or information technology security (IT security) is the protection of computer systems from theft or damage to their hardware, software or electronic data, as well as from disruption or misdirection of the services they provide.

In easy words, Cybersecurity is the protection of Internet-connected systems, including hardware, software and data, from cyber attacks. This is the 2nd best online courses in 2019 as the number of hackers has been increasing day by day.

Importance of Cybersecurity

  • Increasing threats: In a Cybersecurity Ventures report on cybercrimes, the firm projects that the cost of cyber threats will rise to $6 trillion annually by 2021; that amount encompasses everything from damage and destruction of data, stolen money, lost productivity, theft of intellectual property, theft of personal and financial data, embezzlement, fraud, post-attack disruption to businesses, forensic investigation, restoration and deleted hacked data and systems, to name a few.
  • The rising cost of breaches: The fact is that cyberattacks can be extremely expensive for businesses to endure. Recent statistics have suggested that the average cost of a data breach at a larger firm is £20,000.
  • Increasingly sophisticated hackers: Almost every business has a website and externally exposed systems that could provide criminals with entry points into internal networks. Hackers have a lot to gain from successful data breaches, and there are countless examples of well-funded and coordinated cyber-attacks. Ironically, even Deloitte, the globe’s largest cybersecurity consultant, was itself rocked by an attack in October last year.
  • Extensive availability of hacking tools: Well-funded and highly skilled hackers pose a significant risk to your business, the wide availability of hacking tools and programmes on the internet also means a growing threat from less-skilled individuals. The commercialisation of cybercrime has made it easy for anyone to obtain the resources they need to launch damaging attacks, such as ransomware and crypto mining.
  • A proliferation of IoT devices: More smart devices that are connected to the internet are known as the Internet of Things, or IoT, devices and are increasingly common in homes and offices. Therefore, these devices can simplify, speed up tasks, and also offer greater levels of control and accessibility. Their proliferation, however, presents a problem.
