Cybersecurity is one of the most sought-after skills in the modern era. With such a large information pool, and an even larger network of nodes, Cybersecurity has gained a lot of importance nowadays.
This cybersecurity tutorial is designed for beginners as well as professionals. In this tutorial, you will learn all essential skills, tools, and strategies regarding cybersecurity. This cybersecurity tutorial covers the topics from basic concepts to advanced techniques.
What is Cybersecurity?
Cybersecurity is the branch of Information Security that handles the protection and safeguard of networks and data from illegal access or damage. In other words, Cybersecurity is the layer of protection which protects the networks and peripheral data from cyber-attacks and/or information leakage.
Importance of Cybersecurity
Nowadays, most organizations have internal and external networks established to run smoothly and transfer data and other information from one node to another. These network edges and nodes are prone to frequent attacks and data leakage from both intrinsic and extrinsic sources.
Hence, many organizations fund a lot of money to protect their internal information systems. So, why should you study Cybersecurity?
Cybersecurity offers many features, and its importance can be reflected in the following points −
- Protecting our Digital Lives − From your online banking to your social media, your personal information is valuable. Cyberattacks can steal your identity, money, or even ruin your reputation.
- Safeguarding Business − Companies rely on computers and networks to operate. A cyberattack can cause financial loss, damage reputation, and even put people's jobs at risk.
- Defending Nations − Governments and critical infrastructure like power plants, transportation, and healthcare depend on computers. Protecting these systems is crucial for national security.
- Exciting and Rewarding Career − Cybersecurity is a growing field with high demand for skilled professionals. You can work for big tech companies, banks, governments, or even start your own cybersecurity business.
