What is information security?

There has been exponential growth in technology and business in recent years, which has increased the importance of information security. There are top principles of information security, which will be discussed in this article. Cybersecurity is a primary concern, and there are several steps to improve cybersecurity within the organization. Cybersecurity requires constant attention as it is an ongoing concern towards improving and supervising systems’ current state. This can be a drawback due to the increased speed in the technology and the perimeter less organization defying the cultural boundaries and traditional controls’ ineffectiveness.

Information security is a practice that is designed to protect electronics and systems. It also protects confidential information from unauthorized access. It focuses on the confidentiality, integrity, and availability triad. In short, it is also known as infosec. In a specific context, we can call data information. But, they are terms with different meanings. A data is a single unit that contains raw and unorganized facts. Moreover, communication is a meaningful form of data, and it is arranged in a particular fashion or mode.

Why is information security necessary? 

Not only big but also small organizations need protection against security threats and cyber-attacks. The major threats to organizations which have internet spaces are malware and cybercrime. Data breaches take a lot of time, and it is expensive also. Trustworthy and right quality security providers will lead to less severe digital risk, and your system will keep working without any disruptions. However, it depends on the type of organization or the degree of data protection.

Security is necessary everywhere, be it in the home or the organization or on the internet. We went to secure our data and personal information. It would be best if you opted for a security provider to operate it from day to day and one that will fulfill your business needs. A solid relation with a security services provider will increase your organization’s productivity and lead to fewer disruptions and a better reputation.

As we know, that information is one of the most non-tangible assets, and it is the responsibility of the management to protect it. There has been a lot of cybercrime taking place, which scares the organization as organizations rely on compassionate data and customer information. In the 1980s, computers were limited, and computers were only used in limited centers, and they had limited infrastructure. When the internet was introduced, most of the works have been simplified. However, at the same time, weakness is the storage of information security. Internet services have evolved during the time due to communication among trusted groups and reliable sources.

There is also very unnecessary information that has been passed on the internet. Morris worm was the first worm that has infected more than 10% of the systems. And since then, the incidents have increased simultaneously and have become expensive and complicated. To overcome this problem, information security has increased, and many organizations have prioritized making excellent cybersecurity.

What are the benefits of information security?

The quality of the security measures the essential type of information security management provider you choose. It would be best if you were confident about the software you have adequate security that protects your data from unauthorized access and security breaches. It provides you significant benefits and also covers a considerable part of the network security-

  1. It reduces the risk of data disappearances and protects your system from the attacks of viruses.
  2. It has security controls that prevent unauthorized access to sensitive information.
  3. It helps to avoid the disruption of services, for example- denial of services attack.
  4. It protects your data from the exploitation of outsiders.
  5. It ensures the business works in continuity and ensures the protection of data of information assets.
  6. It also provides peace of mind by keeping the information secretive and safe from security threats.

What are the three principles of information security?

There are many threats one has to deal with when accessing information online. The danger is one that weakens the data and leads to the unauthorized access of an electronic system. Some significant threats lead to attacks, such as ransomware, unpatched vulnerabilities, and insider attacks.

Therefore, to minimize these threats, you need to know about the three core principles of information security that have been discussed above, they are (confidentiality, integrity, and availability). They are calculated based on the likelihood, and they impact each other.

1. Confidentiality-

As the name suggests, confidentiality protects the data from unauthorized access. It is easy to implement the restrictions so that only the authorized services can access them. Examples of data confidentiality are unauthorized disclosure, sensitive information theft, and password theft.

There have been times where privacy has been used interchangeably with confidentiality.

2. Integrity-

It protects the completeness and accuracy of the data. This principle ensures that data has not been tampered with and can be trusted. We often get confused with data integrity and data security. Data security deals with the protection of data and whereas data integrity deals with faithfulness. The alertness of data during its transfer is an example of data integrity during unauthorized access. The other concept of virtue is non-repudiation, and it refers to the ability to deny the transaction. Once the legal contract is signed, it cannot be rejected in real life. And a signature is non-repudiation ( none of the parties) can also deny it. Signatures taken digitally are examples of non-repudiation. They are combined to ensure one party to deny the authenticity and integrity of their signature that offers assurance.

3. Availability-

When the authorized user needs data, this is what is called availability of data. If the customers can’t access the data, then the devices, information, and systems are of little value. To ensure data availability, the denial of service attack is a must.

When talking about securing data, that means we need to follow these three principles. The organization may stress the information based on the objective of the business. For example, payroll data would focus on the confidentiality of the personal data which is stored. A bank’s top priority is data integrity so that it protects the data from unauthorized access.

We must keep the above principles in mind to secure data so as the private information remains private and does not get access to unauthorized users.

There is also some other principle-based on these principles, as mentioned above, which are extended to maintain data privacy. There are privacy laws such as the data protection act 2018, GDPR, etc., that are set for protection. There are other principles of GDPR,

  • Data minimization
  • Integrity and confidentiality.
  • Lawfulness, fairness, and transparency
  • Accountability
  • Accuracy
  • Limited storage.
  • Purpose limitation

What are the types of information security?

You can outsource the information given in a digital form entirely or partly.

There are three significant types of information security providers. They offer different benefits and trade-offs.

1. MSP (managed service provider)- 

Security covers a significant part when discussing the package of information technology and the services MSP offers you. This type of service will help you in one-stop shopping, and you know who you should discuss the IIT security issues. It is less expensive than any other specialized security service. However, It does not provide you with a high level of expert services. MSP services will work well with small businesses and other such organizations whose needs are moderate.

2. MSSP (a managed security service provider)-

This type of security service provides system security. It offers you a package to protect your systems from cybercrimes. They hire professionals who are well qualified and up to date in their knowledge. You can pick any of the containers which suit your needs. A good MSSP should be able to satisfy your expectations and protect the information.

3. A security firm providing custom services-

This type of information security works closely to meet your needs and to provide a unique set of services to meet them. Here also there are cybersecurity professionals who will tackle your questions quickly. But the cost of hiring such type of firm is more, but at the same time, it is useful if you expect a high salary from your firm.

Who is responsible for information security?

The workers, managers, directors who are all part of a particular organization are responsible for the information security in a business. Whoever is involved in data handling, making sure that the information is being safely delivered, and remaining vigilant to security threats like hackers are the works that are to be performed by every employee.

There are changes in the firm when some contractors and staff members who are temporary are forgotten when taking decisions as one. However, it is the company’s sole responsibility to ensure people’s participation and adequately train them on information security and awareness.


Information security is an integral part of any organization, as it ensures data safety and provides information about their company and customers. The modern world firms are dependent on the three principles, which are availability, confidentiality, and integrity, to ensure information security.
