Cyber security is the application of technologies, processes and controls to protect systems, networks, programs, devices and data from cyber attacks. It aims to reduce the risk of cyber attacks and protect against the unauthorised exploitation of systems, networks and technologies.

what is cyber security?

Cyber Security is the practice of defending your networks, systems, and applications from cyber threats.

Cyber Security

Digital data and operations are already at the core of most modern organizations, and this trend is only increasing. But with this reliance on computerized systems comes a variety of cyberthreats. ese risks may be internal, originating with employees and contractors. They may be external, the result of activity by cybercriminals or even your own customers. They may be deliberate acts of data theft or disruption, or they may simply be caused by human error and negligence.


No matter where or why a cyberthreat originates, it has the potential to be devastating to companies, their employees, and their customers. That’s why it’s important to understand cyber security practices and tactics for effectively defending against hazards in the digital world.

The importance of cyber security

Today’s organizations face critical challenges with respect to cyber security. Data creation, processing, and storage is increasingly done at the edge, growing operational complexity and making data flows harder to track. Meanwhile, ever-greater computing power and AI are widely accessible, allowing cybercriminals to target businesses more effectively than ever before. And these criminals are highly-motivated, driven by the prospect of multi-million-dollar rewards from businesses that often can’t afford not to pay for the restoration of services or the recovery of lost data. 

Any organization that uses modern technology must contend with the risk of cyberthreats. Taking steps to address this risk is crucial for the health and operational security of businesses. Data breaches and cyber attacks against business services have the potential to cause catastrophic financial and reputational damage, and the unauthorized access of PII can have severe impacts on the lives of employees and customers.

Different types of cyber security

While cyber security often involves digital protective measures, such as antivirus software and user privilege limitations, there are also physical and offline components that can help ensure complete protection against a variety of threats in cyber security.

Some of the primary types of cyber security include:

1.Application security :

preventing data and code in business-critical security software (both in use and in development) from being stolen or hijacked, such as with penetration testing and encryption

2.Information security : 

protecting physical and digital data from unauthorized access and manipulation, both on-site and through remote systems

3.Infrastructure security 

ensuring that the structures and facilities you rely on, such as electrical grids and data centers, are access-controlled and guarded against physical harm or disruption

4.Network security 

securing internal computer networks against unauthorized access, with tools like remote access management and two-factor authentication (2FA)

5.User education

 teaching employees and customers best practices for recognizing and avoiding cyberthreats, such as malware and phishing attacks

Benefits of cybersecurity

By implementing the right cybersecurity solution, an organization can achieve the following 11 benefits:

  • Meet the security requirements of compliance regulations, such as the EU General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), Payment Card Industry Data Security Standard (PCI DSS), Health Insurance Portability and Accountability Act (HIPAA), and ISO 27001.

Why do cyber security attacks happen?

Most often, cyber attacks happen because criminals want your and cyber security recovered your data

  • business’ financial details

  • sensitive personal data
  • customers’ or staff email addresses and login credentials
  • customer databases
