GLOSSARY

An Operating System (OS) is a program that controls a computer's hardware and software resources. The operating system (OS) is responsible for functions like as memory management, process management, and file system management. The operating system also has a user interface and is in charge of duties like maintaining user accounts and permissions. All additional software is loaded on top of the OS, which provides the essential functionality required for a computer to work.

A Virtual Private Network (VPN) is a private network that connects remote locations or people using a public network (typically the Internet). VPNs use "virtual" connections to connect the organization's private network to a remote facility or employee over the Internet. When employees operate remotely, VPNs help keep sensitive data safe from eaves-droppers and hackers. VPNs provide a higher level of security than regular public networks by encrypting data received through the VPN connection.

Multi-Factor Authentication is a security measure which ensures digital users are who they claim they are. Since the chances of some other factor being penetrated by a hacker are minimal if one of the factors has already been compromised, using several authentication factors provides a better level of assurance regarding the user's identity. Whenever you need to present more pieces of evidence to validate your identity in order to obtain access to an app or digital resource, this is known as Multi-Factor Authentication.

OTP BOT is a type of bot that is used to send one-time passwords (OTPs) to users in order to authenticate them.

TLS employs a technique known as a public key encryption, in which two keys, a public key and private key are shared with client devices via the server’s SSL certificate.

Denial of Service (DoS) is an attack in which an attacker attempts to make a system or network unavailable to its users. DoS attacks can be carried out in a number of ways, such as flooding a server with requests or traffic.
