3 Mins read

Cybersecurity is a critical component of the digital world. With the rise of the internet, social media, and mobile devices, people have become increasingly dependent on technology in their everyday lives. However, this reliance on technology has also made them vulnerable to cyber-attacks and data breaches. Therefore, cybersecurity has become a top priority for businesses, organisations, and individuals.  

In this blog, we will define cybersecurity, investigate its various types, and discuss how you can enter or advance your career in the field.

What is Cybersecurity?

Cybersecurity refers to the practice of protecting computer systems, networks, and data from unauthorised access, theft, damage, or other malicious activities. It involves implementing various security measures, such as firewalls, encryption, antivirus software, and intrusion detection systems, to safeguard digital assets and mitigate cyber-attacks.

What are the Types of Cybersecurity?

Cybersecurity is used in various contexts, from business to mobile computing, and can be divided into several broad categories.

  • Network Security: It includes implementing hardware and software to secure computer networks from unauthorised access, modification, or disruption. This type of security assists organisations in protecting their assets from both external and internal threats.
  • Application Security: It focuses on protecting software and devices from unwanted threats. A set of functions or features are added to an organisation’s software to help prevent and rectify threats from cyberattacks, data breaches, and other sources. This can also be accomplished by constantly updating the apps to ensure they are secure from attacks. Examples include antivirus software, firewalls, and encryption programmes.
  • Critical Infrastructure Security: It refers to the protection of essential systems and assets, such as energy, water, transportation, and communication, from physical and cyber threats. The security of the critical infrastructure is crucial for maintaining public safety, national security, and economic stability.
  • Information or Data Security: It involves implementing security measures to protect data confidentiality, integrity, and availability, both in storage and in transit.
  • Mobile Security: It refers to the protection of organisational and personal data stored on mobile devices like smartphones and tablets against threats like malware, phishing, and theft.
  • Cloud Security: It protects cloud-based systems, services, and data from unauthorised access, misuse, or modification through access management, network security, and secure cloud configurations. 
  • Operational Security: It is the process of identifying, assessing and mitigating risks to protect and maintain data asset confidentiality and integrity. This includes the permissions granted to users when they connect to a network as well as the procedures that govern how and where data can be stored or shared. 
  • Internet of Things (IoT) security: It is the protection of connected devices and networks from unauthorised access, attacks, and data breaches through the implementation of secure design, encryption, and monitoring practices.

What are the Benefits of Effective Cybersecurity?

Some of the benefits of effective cybersecurity include the following:

  • Protects sensitive information and data from unauthorised access
  • Prevents cyberattacks and reduces the risk of financial loss
  • Safeguards financial assets and intellectual property
  • Maintains business continuity and reputation
  • Ensures regulatory compliance and avoids penalties
