The optimized services of the internet integrating into everyday business have made possible many operations including social networking, online shopping, and mobile banking. While it certainly has provided us with an abundance of choices and options, it is not without its demerits which is the face of vulnerability that hackers may take advantage of.

Understanding the nitty-gritty of the field will enhance your knowledge of cyberspace and empower you and your organization to further employ strong cyber security measures. Let us uncover the principles of cybersecurity here in this article.

Defining cybersecurity?

The term Cyber security entails securing, safeguarding, and maintaining the cyber environment and digital information which has become an essential part of modern society.

Data is stored, transmitted, and used in an information system. After all, a criminal is looking for information. The network, servers, and machines are nothing more than data conduits. Cybersecurity that is effective decreases the danger of cyber-attacks and protects organizations and individuals against illegal use of systems, networks, and technology. People, systems, and technology are the three pillars of a strong cybersecurity deployment. As attackers get more innovative, it's more important than ever to grasp cyber security fundamentals.

The core Cyber Security Fundamentals

Cyber security is a wide phrase that is founded on three core concepts known as "The CIA Triad." Confidentiality, Integrity, and Availability are the three core principles of cyber security. This triad model is framed to guide organizations in their cyber security policies in the information security field.

Let's take a look at each of these components which forms the cyber security fundamentals.

Confidentiality Fundamental

The term "confidentiality" refers to the practice of not disclosing personal information to other parties who are not allowed to have access to it. It also entails attempting to maintain the privacy and anonymity of authorized parties involved in data sharing and storage. Poorly encrypted data, Man-in-the-Middle (MITM) attacks, and the disclosure of sensitive data are all common ways for secrecy to be jeopardized.

It establishes the rules that govern information access. The precautions taken in order to avoid cybercriminals and hackers from getting access to classified information are referred to as confidentiality.

A few of the standard measures to ensure confidentiality are:

  • Encrypting data
  • Authentication using two factors
  • Verification of biometrics
  • Tokens of security

Integrity

Integrity in information security entails prohibiting unauthorized parties or individuals from altering the information. As per the cyber security policy and law, updating of programs and Information can only be performed in a manner permitted specifically. The two major challenges that could jeopardize the integrity of the organization's system are altering computers into zombie computers and installing malware into the web pages. Integrity ensures that the data is reliable, consistent, and accurate across time. It means that data in transit should not be altered, modified, deleted, or accessed in an unauthorized manner.

A few of the standard measures to ensure Integrity are:

  • Checksums in cryptography
  • Making use of file permissions
  • Power supplies that aren't disrupted
  • Backups of data

Availability

Availability entails the capability of an authorized organization or party of accessing information in times of its necessity. Only when data is accessed accurately by appropriate personnel at the right time it becomes valuable. DDoS assaults, hardware issues, programming flaws, and human errors can all cause the information to become unavailable.

In order to ensure availability, all the necessary components like the systems, hardware, security equipment, software, devices, and networks are to be upgraded ad maintained. Availability ensures the smooth running of the system and the accessibility of data without interruption. Aside from this, sufficient bandwidth is necessary to warrant communication between the components.

Some of the standard measures to ensure availability are:

  • Data backup to external discs
  • Putting up firewalls
  • Having a power supply backup
  • Redundancy of data

All cyber threats have the propensity to jeopardize one or more of the three fundamentals of cyber security- the CIA. And the functioning of all three principles together is vital in keeping information safe and secure. Consequently, it's vital to understand the CIA Triad, how it's used to develop and implement good security policies, and the various theories that drive it.

Types of Cyber security

The types of Cyber security are generally categorized as below:

  • Security of critical infrastructure
  • Application Security
  • Cloud security
  • Network security

Security for the Internet of Things (IoT)

Any company should design a complete plan that incorporates not only these five forms of cybersecurity, but also the three components that play active roles in a cybersecurity posture: people, processes, and technology, to ensure that it covers all of its bases.

As you now have a grasp of the importance of cyber security and how it operates to safeguard and protect the digital ecosystem of any organization, a career in cyber security also forms a good prospect. A cyber security course is ideally the best way for venturing into this demanding and challenging profession. Many job positions also require a cyber security certification that validates the professional's competency. Sign up for any cyber security course and acquire the relevant skills.
