Information Security has a crucial role when it comes to protecting information and business assets. It is the protection of information and system including hardware for storing and transmitting the information. As information is valuable to any organization, it needs protection to enable the safe operation of applications implemented in the organization’s systems. The main objective of information security is to combine systems, operations, and internal controls. This ensures the integrity and confidentiality of data and operation procedures in an organization. Information security also acts as a safeguard to technology and business assets in use at the organization. Overall, it protects the organization’s ability to function.

Presently, many organizations have now adopted to technology ecosystem through the openness of internet-enabled businesses. However, from an information security perspective, it is a great weakness if organizations do not implement proper security systems. With advancements in technologies, security breaches or cyber-attacks are rapidly increasing. This leads organizations to high volatile risk.

A security breach or a cyber-attack can cause serious problems and incalculable damage to an organization. Yet, many small and medium business organizations tend to neglect their information security. They fail to acknowledge that they are susceptible to being a potential target of the next attacks. So, they do not think of investing in the data or information security industry. Leveraging this advantage, many attackers have become successful to target such organizations due to their weak security systems. It even causes a potential threat or damage to their information and business assets. Ultimately resulting in financial fall-down, bankruptcy or even shutdown of organizations.

No matter the size, capital, or function of the business, today’s organizations require strong information security policies and management systems. As information security sums up people, processes, and technology, it plays an essential role in protecting information and business assets. In addition, it not only protects but also prevents the unauthorized disclosure, access, use, and modifications, of those information and business assets. Similarly, information security consists of three major principles, or three primary tenants known as the CIA triad: Confidentiality, Integrity, and Availability. These principles are highly effective when implementing an information security management system in an organization.

Data or information is very confidential when it comes to authorization to its access. In information security, confidentiality is the essential factor of the CIA triad. It allows an organization to identify the unauthorized activity that is trying to access data and will block its attempts. Confidentiality ensures that only trusted people can access the information. It also makes sure to prevent or maintain the confidentiality of information. Confidentiality has a lot to do with technology. It helps to protect data and ensures only the right people have access to the data.

In the context of information security, integrity means that data modification is not possible without authorization. It maintains the identity of data in its correct state. It also prevents information alteration from either accidental or malicious activity. Well-protected security disables unauthorized activity through infected computers like deletion of files, information theft, etc. Most of the methods that ensure confidentiality will also protect data integrity. Thus, cyber attackers or hackers cannot change the data as they cannot access it. Apart from that, version control software and frequent backups can also assist to restore data to its correct state.

By far, we know that any business or organization must make sure their data is inaccessible by unauthorized users. Nevertheless, they should also ensure that the access is not in misuse by those who have proper permissions. Consequently, availability also refer as the mirror image of confidentiality. Furthermore, the availability of information is equally important for any information system to serve its purpose. In addition, availability systems that are always available also prevent service disruption, hardware failure, and system upgrades.

Due to globalization and technology creating transformation, information and business assets need to be in a secure state. Therefore, information security is essential and acts as a guardian protector for data or information from threats and cyber-attacks.
