Everyone will agree to the fact that information assets are critical to any business and paramount to the survival of any organization in today's global market. As there has been a rise in the cyber crimes, such as hacking, data thefts, data losses and virus attacks in the networking and software related jobs, the need of information security is growing by leaps and bounds.

Components of Information Security

Typically information security comprises of five components, such as:

1. Confidentiality

Information security ensures that information is shared only among authorized persons, within or outside the organization. Breaches of confidentiality happen due to improper handling of data through printing, copying, e-mailing or creating documents, etc.

2. Integrity

With proper information security, there is also the assurance of the information being authentic and complete. The term 'integrity' is regarded as the indicators of information security or lack of it. The integrity of data is not just restricted towards the correctness of data but it also verifies whether the data can be trusted and relied upon.

3. Availability

In information security, the person in charge of it makes sure that the systems can be accessed by authorized people whenever needed. It helps in delivering, storing and processing data in a responsible manner.

4. Accountability

Since there are different departments in an organization, confidential information needs to be protected and secured with utmost care. Most organizations build a culture of confidence in their employees, and all employees, particularly in senior and responsible positions understand that internal information and data is not to be shared or divulged to unauthorized persons. Some organizations also have specific departments where the people are entrusted with the responsibility of protecting the assets and confidential data .

5. Audit-ability

This component of information security has got two parts. Firstly, any system must be able to backtrack as that one can determine the positioning of the system during any emergency. Secondly, with auditing it becomes sure that the systems have all the necessary documented requirements.
