What are the pillars of information security?

Information security plays a key role in securing the data against any unauthorized access or alteration. Data leakage or any other security breach can be a reason for financial loss to the company.

The security of the company is dependent upon some crucial building blocks. They help to lower the risk of being the victim of security issues.

Security threats can be prevented by using an effective system containing all the pillars of securing the information.  There are five pillars of information security:

Pillars of Information Security

Five Pillars of Information Security:

  1. Integrity
  2. Confidentiality
  3. Availability
  4. Authenticity
  5. Non-Repudiation

1. Integrity

This pillar of information security helps to maintain the originality of the data or information. There must not be any alteration in the data without authorized access.

If an unauthorized person accesses the system of the organization it can cause inappropriate changes to the data. It results in breaching the integrity of the system. There must be a proper mechanism to maintain the integrity for securing the data from any sort of improper alterations. 

2. Confidentiality

It refers to controlling the access of the users to the system. It helps to prevent unauthorized access to the system.  Harming confidentiality can leads to issues like cyber-attacks and many more.

Password authentication can be helpful in this concern. User or admin passwords can be set to control access. Biometric scans and encryption are some other ways to attain confidentiality.

If the confidentiality of the system is breached then integrity is also at risk. So there must be comprehensive planning to keep your system away from any sort of security breach. It can never be compromised for attaining the protection of confidential or important data. 

3. Availability

Data and information must be available whenever it is required. It is another considerable factor to attain information security.

Availability needs continuous and stable access to the system without any interruption with the help of quick maintenance and debugging.

Otherwise, multiple threats can be generated like denial attacks, etc. Thus, there must be a plan or mechanism to avoid this issue.

4. Authenticity

It helps to check the validity of the information that is being sent. It also assists to check the authenticity of the senders or the receivers. This pillar of information security averts impersonation.

The user’s identity must be verified before attaining access to the system of the organization or its resources.

This process involves the email, password, biometrics, user names, etc. strong passwords must be set by the users to keep the system secure. It is also helpful in keeping the system secure from illegal access.

5. Non-Repudiation

This pillar of information security involves the surety of providing the delivery proof to the sender of information. It also includes the provision of the proof regarding sender’s identity to the receiver.

The sending, receiving, and accessing of the data can never be repudiated or denied by anyone in this manner. Adequate security ethics must be maintained to ensure the validity of the communication procedure and to verify identities.

It is quite a helpful aspect to ensure the secure delivery of the information.

The Supporting Mechanism

These practices support the five pillars of information security to propose complete frameworks to acquire the protection of the data or information.

They involve identification and authentication, access control, and non-denial. These structures help to verify whether the person who is trying to access the system is authorized or not.

Password authentication, encryption, and various other technical aspects can be considered in this concern. Thus, it helps to control the access of the users to the company’s system.

It prevents data loss or leakage and secures the complete system against any security threat. 

All the aforementioned pillars must be considered in proposing an inclusive mechanism to ensure the systems’ security. Some support practices work with these pillars to deliver the required outcomes.

We must keep all five pillars and supporting mechanisms to attain comprehensive security for the system. The financial loss of the company can be prevented by considering the main pillars of information security for proposing a complete security framework.

We can never neglect them to ensure better security of the company’s assets or resources. The access of unauthorized persons can be denied by using the efficient framework for attaining better security services.
