What Is Cyber Security | How It Works? | Cyber Security In 7 Minutes

What You Will Learn

• Understand the concept of cyber security and its importance in protecting digital components, networks, and systems from unauthorized access.
• Identify common types of cyber attacks, such as malware, phishing, and man-in-the-middle attacks.
• Learn basic cyber security practices to prevent future attacks, including the use of firewalls, honeypots, and unique passwords.

Key Concepts

Cyber security refers to the techniques used to secure digital components, networks, and systems from unauthorized access. A cyber attack is an attempt by a hacker to gain access to a system or network, often to steal sensitive data or install malware. Phishing attacks involve sending fraudulent emails that appear to be from a legitimate source, in order to steal sensitive data or install malware. Firewalls act as a virtual wall between a computer and the internet, filtering incoming and outgoing traffic to safeguard the network. Honeypots are dummy computer systems that are made to look vulnerable, in order to attract and deceive attackers.
