In other words,

Information security is defined as the practice of allowing access to individual or business information to people in an organization.

Difference between cybersecurity and information security

Many people often get confused between cybersecurity and information security. These are treated as buzzwords in security. These are used as synonyms, goes hand-in-hand in ‘Security Terminology’.

Cybersecurity is the process of protecting confidential data from third-party sources on the internet. A cybersecurity expert is responsible to provide security for – internet, intranet and servers. Also, assures that the information can be accessed by authorized people.

Information security is considered as protecting data systems from unauthorized person. It prevents the hacker from accessing, modification or stolen the information.

Businesses and individual that use laptop and desktop can describe their requirement for using information security in systems – 3 common requirements.

  • Confidentiality
  • Integrity
  • Availability


Confidentiality plays a major role in information security.

Have you just shared a legal document to an unauthorized person? Then you’re on risk. Protecting important document from a hacker is the major concern for entrepreneurs.

Confidentiality indicates to protecting important data from being accessed by a third person or unauthorized parties. Let’s keep it simple – the people who have gained authorization access to confidential information.

For example – Bank records

You’re responsible to access your bank information. Of course, the bank employee also has access to your bank details. Those employees assist you while transaction and transferring money. But nobody else can access your bank details.

Never ever share the confidential information to the third party. Because when you fail to maintain confidentiality then everything gets ruins. These type of failure is considered as a breach (remedied). When you share top-secret to untrusted person, they will reveal it to everyone. If your bank details are been posted on public sites, then everyone gets a chance to know your bank information.


Integrity indicated – assuring the authenticity of data. It simply means that information is not accessed by an unauthorized person or third parties. As a result, the data is not altered and deleted. As a result, the information is safe and secure.

You’re running an e-commerce website and you offer fashion and electronic products. Just imagine a hacker visited your website and altered the cost of your product. That means they can buy anything from your website at their price choice. In this case, the cost of your product has been modified by an unauthorized person. Ultimately when you confirm the order from the hacker, you end-up with loss.


Availability indicates that data or information is available for an authorized person at any time. If the hacker isn’t able to negotiate the first two elements (confidentiality and integrity) of information security. Then the hacker can implement other security attacks such as a “denial of service”. By implementing this attack, the server may perform low. Making the website or blog unavailable to authorised users due to lack of ‘availability’.

What is meant by security?

An attack is defined as an information security threat that involves an attempt to obtain, delete, update, modify, reveal confidential information without permission. This can happen for a small, medium and large business.

There are two types of attack in Information Security

  • Active attack

An active attack is a process of attempting to modify system resources. Also, effect their ongoing operations. It involves a few alterations of the information stream. Sometimes, an active attack can create a false statement. There are various types of active attack such as masquerade, modification of message, repudiation, reply and denial of service.

A passive attack attempt to acquire or make usage of data from the system. But the passive attack doesn’t affect system resources. These type of attacks are eavesdropping. They monitor the ongoing transmission.

The goal of passive attack is to access and alter the information that is being transmitted. Types of passive attacks are traffic analysis and release of message content.
