Cyber security.
Cyber security is the application of technologies, processes and controls to protect systems, networks, programs, devices and data from cyber attacks. It aims to reduce the risk of cyber attacks and protect against the unauthorised exploitation of systems, networks and technologies.
Computer security.
security, cybersecurity, or information technology security (IT security) is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.[1]

While most aspects of computer security involve digital measures such as electronic passwords and encryption, physical security measures such as metal locks are still used to prevent unauthorized tampering.
The field is becoming increasingly significant due to the continuously expanding reliance on computer systems, the Internet[2] and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of "smart" devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is also one of the significant challenges in the contemporary world, due to its complexity, both in terms of political usage and technology. Its primary goal is to ensure the system's dependability, integrity, and data privacy.[3][4]
History of cyber security.
Cybersecurity began in the 1970s when researcher Bob Thomas created a computer programme called Creeper that could move across ARPANET's network, leaving a breadcrumb trail wherever it went. Ray Tomlinson, the inventor of email, wrote the programme Reaper, which chased and deleted Creeper.
what is reaper?
Reaper was the very first example of antivirus software and the first self-replicating programme, making it the first-ever computer worm.
1980s: Birth of the commercial antivirus
1987 was the birth year of commercial antivirus although there were competing claims for the innovator of the first antivirus product. Andreas Lüning and Kai Figge released their first antivirus product for the Atari ST – which also saw the release of Ultimate Virus Killer in 1987. Three Czechoslovakians created the first version of the NOD antivirus in the same year and in the US, John McAfee founded McAfee and released VirusScan.
firewalls and antivirus programmes had to be produced on a mass basis to protect the public.
2000s: Threats diversify and multiply.
In the early 2000s crime organisations started to heavily fund professional cyberattacks and governments began to clamp down on the criminality of hacking, giving much more serious sentences to those culpable. Information security continued to advance as the internet grew as well but, unfortunately, so did viruses.
2021: The next generation.
The cybersecurity industry is continuing to grow at the speed of light. The global cybersecurity market size is forecast to grow to $345.4bn by 2026 according to Statista. Ransomware is one of the most common threats to any organisation's data security and is forecast to continue to increase.
