The practise of protecting networks, computers, servers, mobile devices, electronic systems, and data from hostile attacks is known as cyber security. It is often referred to as electronic information security or information technology security. The phrase can be broken down into a few basic categories and is used in a wide range of applications, including business and mobile computing.


Cybersecurity is the process of preventing hostile assaults on internet-connected systems such computers, servers, mobile devices, electronic systems, networks, and data. Cybersecurity can be divided into two categories: security and cyber. Technology that incorporates systems, networks, programmes, and data is referred to as "cyber." The safeguarding of systems, networks, applications, and information is also a concern of security. It may also go by the names information technology security or electronic information security.

Types of Cybersecurity

  • Network Security: It is the process of protecting a computer network from intruders, including malicious software and targeted attacks. It involves putting in place the technology and software necessary to protect a computer network from misuse, unauthorized access, intrusion, attacks, and interruption. An organization can better safeguard its assets by using this security against both internal and external dangers.


  • Information Security: Data integrity and privacy are safeguarded while being stored and transported. To protect data integrity and privacy during both storage and transmission, a reliable data storage system must be put in place.


  • Application Security: It focuses on keeping tools and software safe from dangers. The data that an application is meant to safeguard may be accessible if it is compromised. Effective security starts at the design phase, long before a program or gadget is put into use. Update the apps frequently to keep them safe from threats to provide this security.


  • Operational Security: It consists of the procedures and choices made for managing and safeguarding data assets. This includes the policies that regulate how and where data may be stored or exchanged, as well as the permissions people have when accessing a network.


  • Mobile Security: It includes protecting against various dangerous threats to the organizational and personal data held on mobile devices like cell phones, PCs, tablets, and other comparable gadgets. These dangers include malware, unauthorized access, device loss or theft, etc.


  • Cloud Security: It includes protecting the data kept by the organization in a digital environment or cloud architecture. To maintain security against a variety of threats, it makes use of many cloud service providers like AWS, Azure, Google, etc.


  • Disaster recovery and business continuity: It describes the actions taken by a company in the event of a cyber security incident or any other occurrence that results in the loss of operations or data. Disaster recovery procedures specify how the organization restores its activities and information to resume normal business operations. The organization's backup plan, when certain resources are unavailable, is business continuity.


  • Identity Management: It deals with the method for figuring out what level of access each person has inside an organization.


  • User Education: It deals with humans as the most unpredictable factor in cyber security. Anyone who disregards sound security procedures has the potential to unintentionally introduce a virus into a system that is otherwise secure. For the security of any organization, it is crucial to teach users to delete suspicious email attachments and to avoid plugging in unknown USB drives, and other key teachings.

Importance of Cyber Security in Digital World

Today, networks, computers, and other electronic devices as well as software applications are essential to every aspect of our lives. Devices connected to the Internet are a vital component of all key infrastructure, including the banking system, healthcare system, financial institutions, governments, and manufacturing sectors. Some of their data, including intellectual property, financial information, and personal information, may be delicate and vulnerable to unauthorized access or exposure, which could have unfavorable effects. The ability to penetrate them for financial gain, extortion, political or social objectives, or even vandalism, is made possible by this information for intruders and threat actors.


The global economy could be put in jeopardy by further security breaches and the growing worldwide concern over cyberattacks that compromise systems. To safeguard sensitive data against public security breaches, it is crucial to establish a strong cybersecurity plan. Furthermore, in order to protect their sensitive customer and employee data from cyberattacks, businesses, and organizations—particularly those that deal with data pertaining to personal or public health, national security, or financial records—need to implement robust cybersecurity procedures.

Importance of Cyber Security in Business/Organizations

The target data breach is an example of how crucial cyber security is for businesses and organizations. In this instance, hackers were successful in getting access to consumer data from the target, including credit and debit card details. Target was forced to pay millions of dollars in damages as a result, and its reputation with customers suffered. The Target data breach is only one illustration of the significance of cyber security for businesses and organizations.


The WannaCry ransomware outbreak, which hit businesses and organizations around the world, is another illustration of a data breach. Many organizations lost data and money as a result of this attack, and some were even forced to shut down.


The 2014 JPMorgan Chase data breach serves as a practical illustration of the significance of cyber security for the banking industry. The names, addresses, phone numbers, and email addresses of 76 million households and 7 million small businesses were exposed to hackers in this attack. The hackers also had access to 83 million JPMorgan Chase clients' account details, including account numbers and balances.


Due to the fact that hackers were able to access a significant amount of private client information, this breach serves as a reminder of the value of cyber security for the banking industry. This information may have been misused for identity theft, fraud, or other nefarious activities if it had gotten into the wrong hands.
