The application of technology, procedures, and policies to safeguard systems, networks, programs, devices, and data from cyber threats is known as cyber security.
Its purpose is to reduce the danger of cyber-attacks while also protecting systems, networks, and technology against unwanted access.
Cyber security is a strategy for preventing harmful assaults on computers, servers, mobile devices, electronic systems, networks, and data. It’s also known as information technology security or electronic information security. The term is used in a variety of applications, from business to mobile computing, and it may be divided into several groups.
- The practice of securing a computer server against intruders, whether targeted hackers or opportunistic malware, is referred to as network security.
- App security is concerned with preventing threats from entering software and devices. A hacked application might provide others access to the information it was supposed to keep safe. Security starts with the planning phase, long before a program or device is deployed.
- Data integrity and privacy are protected in both storage and transit by information security.
- The activities and decisions that go into handling and protecting data assets are referred to as operational security. The protocols that regulate how and where data may be kept or exchanged, as well as the permissions people, have when accessing a network, come under this category.
- Disaster response and contingency planning are terms used to describe how a company reacts in the case of a cyber-security breach or any other catastrophe that results in the loss of operations or data. Disaster response policies define how an organization returns operations and information to the same operational capabilities as before the disaster. Contingency planning is the plan that an organization uses when it is unable to operate due to a lack of resources.
- End-user education focuses on the most unexpected aspect of cyber-security: people. By failing to follow appropriate security measures, anyone can unintentionally introduce a virus into an otherwise protected system. It is critical for every organization’s security to teach users to delete suspect email attachments, not plug in unrecognized USB drives, and a variety of other key teachings.

Cyber security breaches are becoming more expensive
Organizations that experience cyber security breaches may face large fines under privacy rules such as the GDPR (General Data Protection Regulation) and DPA (Data Protection Act) of 2018. There are other non-monetary expenses to consider, such as reputational harm.
The sophistication of cyber-attacks is increasing
Cyber attacks are becoming more sophisticated, with attackers employing a wider range of strategies. Social engineering, malware, and ransomware are examples of these.
Cyber security is a serious issue
Cyber security is a serious issue that should be addressed at the board level.
Cyber security risk oversight is becoming more difficult due to new legislation and reporting requirements. Management must assure the board that its cyber risk policies will lower the risk of attacks while also limiting financial and operational consequences.

Cybercrime is a multibillion enterprise
According to The Invisible Costs of Cyberattacks, a 2020 study conducted by McAfee and the CSIS (Centre for Strategic and International Studies) based on data gathered by Vanson Bourne, the global economy loses more than $1 trillion each year. Attackers may be motivated by political, economic, or societal reasons.
