The practises that are outlined in a variety of studys and referred to collectively as "cyber security" are intended to safeguard the online presence of a user or an organisation. It is responsible for coordinating the many tools and processes that are necessary to avoid harm to networks, software, and data. Another term for this grouping of technologies and processes is information technology security (IT security). The prominence of the industry is growing as a result of an increased reliance on computer systems such as smartphones, televisions, and the myriad of other tiny devices that comprise the Internet of Things. The internet has made it easier to communicate with people all over the globe in a variety of ways; but it has also presented us with an abundance of new influences that were previously unfathomable. At the same time as the world of security developed, the world of hackers also expanded. Two distinct points of view may be taken into consideration while of cyber security. One advantage is that cloud service providers focus exclusively on this area, which means that their customers can be certain that they are using the most cutting-edge encryption technology currently on the market. In the event of a cyberattack, it is being protected by internet-connected devices, which protect not just the data but also the hardware and software. Organisations take safeguards against hackers and other bad actors by using both cyber security and physical security measures for their data centres and other computerised systems. These procedures are designed to protect against the risk of unauthorised access. The goal of the cyber security subfield known as data security is to maintain the confidentiality, integrity, and accessibility of stored information. The breadth of operations that comprise cyber security includes the protection of data and infrastructure against major dangers that may be found online. There is a diverse range of these threats to consider.
