Cybersecurity, computer safety or computer security is basically the protection of networks and computer systems against external information access, malicious attacks or destruction of their hardware, applications, or digital data, and from the unintentional disruption or distortion of their services. The attacks on computer networks come from various quarters like viruses, worms, Trojan horses, spyware, and hacker attacks, spamming, and email viruses. They can originate from an insider within a company (unauthorized employee), an external source such as a government agency, or a third party, usually a hacker. It is quite possible that no one will ever know that the cyber security has been breached, but by implementing good security practices, it will greatly help in the prevention and the reduction of cyber security risks.
