A Quick Guide To Understanding Cybersecurity

Cybersecurity has become a popular topic these days. However, do you know its importance? Today, we live in a digital age where data is of utmost importance. Private information has become more vulnerable than before. Often, we hear about identity theft cases and data breaches that affect thousands of consumers. All institutions and companies fight to protect their private data against cybercriminals and hackers. Cybersecurity is not just involved in companies, but even personal tablets, mobile phones, and computers.

What Is Cybersecurity?

The answer to the question, “What is Cybersecurity” is simple. It is a practice of protecting data, programs, networks, systems, and devices against attacks. The cyber-attacks are created to use vulnerabilities in an enterprise’s system or individual’s device to disable, destroy, control, or disrupt their infrastructure or data. Good cybersecurity includes various layers of protection for data, programs, systems, networks, and devices or an organization. A combination of best practices and technology can offer an efficient defense against the constantly growing and evolving threats of cyberspace. Such threats can include malware, phishing, code injections, ransomware, and more. Their impacts can differ based on the attack’s scope. A cyber-attack can lead to the attacker making illegal purchases with a person’s credit card or erasing a whole system by injecting malware into an enterprise’s code base. Though the best cybersecurity cannot defend against each instance or type of cyber-attack, it can assist in minimizing the impact and risk of these attacks. Now that you have understood what cybersecurity is, read on to find out what is the CIA triad and how it relates to cybersecurity.

CIA Triad

An organization’s security begins with three principles. They include Confidentiality, Integrity, and Availability. It forms CIA Triad. It has served as the standard for cyber security since mainframes.

Confidentiality – Confidentiality principles assert that authorized parties only can access sensitive and private functions and information.

Integrity – Integrity principles assert that authorized means and people only can alter, remove, or add sensitive functions and information.

Availability – Availability principles assert that data, functions, and systems should be accessible on demand as per the agreed-upon parameters.

Cybersecurity Specialities

If you are looking to pursue a career in cybersecurity, you should know about the different areas of specialization. Below are the areas of specialization in cybersecurity:

  • Access Control System and Methodology
  • Telecommunication and Network Security
  • Security Models and Architecture
  • Security Management Practices
  • Law, Ethics, and Investigation
  • System and Application Development Security
  • Computer Operations Security
  • Cryptography
  • Physical Security


Cyber-attacks can be intimidating. However, cybersecurity does not need to be. It is vital to be armed and prepared, particularly if you are handling others’ data. As the cybersecurity field continues to change and grow, introducing new vulnerabilities and threats, cybersecurity professionals should prepare themselves with the skills needed to protect the availability, integrity, and confidentiality of data.
