Cybersecurity, also known as computer security or IT security, deals with protecting computer systems from theft of information; damage of hardware, software, or data; the disruption of services through denial-of-service attacks or the misdirection of services through botnets. The field of cybersecurity is rapidly growing in importance as the world increasingly relies on the Internet and wireless networks, computer systems, smart devices, and the many devices that make up the Internet of Things.

There are numerous vulnerabilities, possibilities for exposure, and attacks that companies should be aware of, including backdoors that allow bypassing of security, denial of service attacks, direct-access attacks, eavesdropping, phishing, privilege escalation, social engineering, tampering, spoofing through use of emails, IP addresses, Media Access Control addresses, and biometric samples, and the new type of multivector, polyrhythmic cyber threats, classified as fifth-generation cyber-attacks.
