Lesson 1.1  What is Cybersecurity?

Overview:
Cybersecurity is the practice of protecting computers, networks, mobile devices, and data from digital threats such as hacking, malware, and unauthorized access. It plays a vital role in ensuring that the information we use, share, and store online remains private and trustworthy.

Detailed Explanation:
In today’s world, almost everything we do involves technology  from banking and education to communication and entertainment. This digital dependence has created opportunities for criminals who exploit system weaknesses for personal gain.

Cybersecurity acts as the digital shield that defends against such threats. It combines tools, technologies, and best practices to secure systems and reduce risks.

Cybersecurity involves everyone from individuals securing personal devices to organizations protecting business operations and governments safeguarding national data. These attacks are usually carried out by hackers to:

1. Access, change, or destroy sensitive information.

2. Interrupt normal business processes.

3. Steal money or data.

In simpler terms, cybersecurity is like locking your digital doors and windows so that intruders can’t break in.

Key Takeaways:

• Cybersecurity protects against cyberattacks that can lead to financial loss or identity theft.

• It’s built on the principles of confidentiality, integrity, and availability.

• Everyone using technology has a role to play in maintaining security.
