Understanding The Definition Of Information Security

The Definition and Importance of Information Security

Information security, frequently referred to as infosec, is a set of processes and measures that are designed to protect digital and non-digital information from unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction. It is deeply connected to ensuring confidentiality, integrity and availability, which are key aspects of any kind of information.

Information systems are increasingly becoming a prime target for a wide range of threats – from amateur hackers to professional cybercriminal gangs and even state-sponsored attacks. Without proper measures for protecting information, businesses and individuals alike can be made vulnerable to various types of information security breaches, with potentially disastrous consequences.

Role of Cyber Security

While cyber security consulting often comes hand in hand with information security, it is crucial to note that they are two different things. Cyber security focuses more on defending data and systems from cyber threats such as hacking, viruses, data breach, and more. Information security, on the other hand, is a broader category that includes cyber security. It is concerned with protecting all information – whether digital or physical – from unauthorized access, use, and other threats.

Components of Information Security

Information security revolves around three fundamental concepts also known as the CIA triad:

  • Confidentiality: This implies that information should be available only to those authorized to access it.
  • Integrity: This principle stipulates that only authorized parties can modify the data. From a security management perspective, it comprises both data integrity – the accuracy and constancy of data – and system integrity – the working state of systems.
  • Availability: This ensures that authorized parties can access the data whenever needed.


The complexity and scope of the challenges associated with information security mean that organizations often need to seek outside help in order to effectively address them. Fortunately, there are many companies offering cyber security consulting services to help businesses protect their critical data.

In conclusion, information security is the backbone of today’s digital world. It encompasses various protective measures and best practices designed to prevent unauthorized access, use, disclosure, disruption, modification, or destruction of information, whether that information is digital or not. By partnering with cyber security consulting firms, businesses can bolster their information security posture to minimize the likelihood of a costly and damaging breach.
