What is Information Security?

Information Security, also known as infosec, is the practice of preventing unauthorized access, use, disclosure, modification, infection and destruction of your company’s information.

These unauthorized practices can cause grave results for your company. The whole framework of information security is built around six principles: Confidentiality, Integrity, Availability, Non- Repudiation, Authenticity and Accountability.

1) Confidentiality

This principle means that the confidential information of your company is not disclosed to individuals, entities and process.

2) Integrity

This principle means that the data or information of your company can in no way be edited without any given permission. It contributes to maintaining the accuracy of the data.

3) Availability

This principle means that the information should be available or accessible whenever required.

4) Non-Repudiation

This principle ensures that the parties involved in a contract or document transfer are unable to deny the authenticity of their signatures on the documents or that they were the originator of a particular transfer.

5) Authenticity

This principle ensures that those who claim to be who they are in actual fact who they say to be. It ensures that valid messages are received from trusted sources.

6) Accountability

This principle means that it should be possible to trace the actions performed on a system to a specific system entity such as user, process, device.

Why is Information Security Important?

Considering the importance of the role of confidential information to your company, it is best that you immediately take steps to protect your information.

You can just imagine what will happen if all your company’s confidential information was to be harmed. The results will be disastrous. Your company’s image will be affected, your plans and secrets will be exposed among many other severe consequences.

A cyber attack can cause serious damage to your company. Not only will your entire company be in danger, but also your customers and business partners as their associated data too will be vulnerable.

But keep in mind that it is not only the big companies who are vulnerable to these attacks. Small businesses generally tend to believe that their system won’t be attacked due to which they do not invest in information security system.

But this is the major reason is to why most of the attacks are usually targeted towards small businesses. The losses faced by large companies due to these attacks generate media attention even if the material stolen is small. On the other hand, for small businesses even if a fraction of their material is stolen, it can very much lead to the shutting down of their businesses. It can lead to bankruptcy as the stolen information can cause financial problems.

Therefore, information security poses to be of great importance. For this very reason, professional and skilled individuals are required to oversee the security system effectively. These individuals will stop any sort of infiltrations that initially was left undetected.

Organisations must also do their bid to ensure the implementation of an effective information security system. It is important to promote awareness of information security which can be done through training and initiatives. Security policies should also be enforced and undergo renewal regularly.
