What is Cyber Security and Why Does It Matter Today?

Introduction

Cyber Security Online Training, almost every aspect of our lives is connected to the internet—whether it's banking, shopping, communication, or even healthcare. While this connectivity brings convenience, it also opens doors for cyber threats. Cyber security, the practice of protecting systems, networks, and data from digital attacks, has become more important than ever. As cybercriminals develop increasingly sophisticated tactics, businesses and individuals alike must stay informed and take proactive measures to safeguard their digital assets.

What Is Cyber Security?

Cyber security refers to the strategies, technologies, and practices designed to protect computers, networks, and data from unauthorized access, attacks, or damage. It involves various measures that defend against cyber threats, including malware, phishing, ransomware, and data breaches. Cyber Security Classes

The main goals of cyber security are:

Confidentiality: limiting access to sensitive information to those who are permitted

• Integrity: Maintaining the accuracy and reliability of data.

Availability: ensuring sure systems and data are available when required..

 Types of Cyber Security Threats

Understanding the different types of cyber threats can help individuals and businesses prepare and protect themselves more effectively. Here are some common cyber threats:

1. Malware Attacks
   Malicious software, or malware, includes viruses, worms, spyware, and ransomware. Once installed on a system, malware can steal, encrypt, or delete sensitive data.
2. Phishing Scams
   Phishing attacks use deceptive emails or websites to trick users into providing personal information, such as passwords or credit card numbers. These scams often appear legitimate, making them difficult to detect.
3. Ransomware
   Ransomware locks users out of their systems or encrypts data, demanding a ransom to restore access. These attacks have targeted businesses, hospitals, and even government agencies.
4. Man-in-the-Middle Attacks
   In this attack, cybercriminals intercept communication between two parties to steal sensitive information or inject malicious content.
5. Denial-of-Service (DoS) Attacks
   DoS attacks overwhelm a system’s resources, making it unavailable to users. Distributed DoS (DDoS) attacks amplify this by using multiple systems to launch the attack simultaneously.
