🔍 What is Cybersecurity?

Cybersecurity refers to the practice of protecting systems, networks, devices, and data from unauthorized access, cyberattacks, and digital threats. The main goal is to keep information safe, secure, and private.

Cybersecurity defends against:

• Data breaches
• Identity theft
• Ransomware attacks
• Phishing scams
• Viruses and malware

💡 Simply put: Cybersecurity = digital security.

⚙️ How Does Cybersecurity Work?

Cybersecurity works by combining technology, processes, and best practices to:

1. Detect threats early
2. Prevent unauthorized access or damage
3. Respond to attacks quickly
4. Recover from security breaches

🔒 Core Components of Cybersecurity:

1. Network Security – Protects internal networks from intrusions (e.g., firewalls, VPNs)
2. Application Security – Secures software and apps from vulnerabilities
3. Information Security – Safeguards data integrity and privacy
4. Endpoint Security – Protects devices like laptops, mobiles, and tablets
5. Cloud Security – Defends cloud-based data and services
6. Operational Security (OpSec) – Ensures secure handling of data in day-to-day operations
7. Disaster Recovery – Helps restore systems and data after a breach
