What is Cyber Security?

In today’s world, everyone uses internet computing devices such as smart phones, laptops, and tablets. These devices are generally used by users to communicate with each other via emails or social media, and to surf the internet for online shopping or entertainment.

Overall, the internet has made our lives more comfortable and efficient. However, there can be another side to the story. Many personal data and that of our businesses and assets, which are stored in our own computers and within the system of others can be at serious risk.  Despite that, cyber security can protect, prevent, detect and respond to any cyber-attack.

Essentially, all cyber security definitions point to the security of the cyberspace; namely all:

  • Interconnected ICT hardware and software infrastructure
  • Data in transit and at rest on the networks
  • Connected users
  • Logical connections established among them

In view of the above, the following definition of cyber security being adopted by the National Cyber Security Strategy is:

It is the safeguards and actions that can be used to protect cyber domain from those threats that are associated with or that may harm its interdependent networks and information infrastructure. It strives to preserve the availability and integrity of the networks and infrastructure and the confidentiality of the information contained therein.

Cybersecurity is the preparation of securing the systems, networks and programs from digital attacks. These attacks are aimed at accessing changing, or destroying sensitive data.  Cyber security is based upon the foundations of information security, namely confidentiality, integrity and availability. Information security aims to safeguard citizens and reduce cyber space risk. The inherent interconnectedness of cyber-space exposes all of its constituents to a failure of their most vulnerable elements.

Additionally, effective cyber security cannot be reached by technological measures alone as modern cyber attacks could bypass all defence layers by exploiting human factors through techniques such as social engineering.

Hence, safeguards and actions hereby refer to ongoing and planned measures which may potentially be of technical, operational, legislative, educational, behavioural or disseminative nature.

Above all, cyber security cannot be seen from a technological aspect only. It needs to cover the needs and expectations of the state, the economy and society, all of which are increasingly active participants in an interactive digital world.
