What is Cybersecurity?

Cybersecurity is the practice of protecting internet-connected systems, networks, and data from cyber threats. It involves technologies, processes, and strategies to defend against attacks like hacking, data breaches, and malware.

Types of Cybersecurity

1. Network Security – Protects networks from unauthorized access and cyber threats.
2. Application Security – Secures apps through secure coding and updates.
3. Information Security – Ensures data integrity and privacy.
4. Identity Management – Controls access levels within an organization.
5. Operational Security – Manages how data is stored and accessed.
6. Mobile Security – Protects data on mobile devices.
7. Cloud Security – Secures cloud-based data and services.
8. Disaster Recovery – Plans for recovery after cyber incidents.
9. User Education – Trains users to recognize and prevent cyber threats.

Importance of Cybersecurity

With increasing cyber threats, cybersecurity is crucial for protecting sensitive data, financial systems, government infrastructure, and personal information from unauthorized access and cyberattacks.

Cybersecurity Goals (CIA Triad)

1. Confidentiality – Ensures only authorized users access information.
2. Integrity – Prevents unauthorized modifications to data.
3. Availability – Ensures data is accessible when needed.

Common Cyber Threats

• Malware – Viruses, spyware, trojans, ransomware, worms, adware, and botnets.
• Phishing – Fraudulent emails or messages trick users into revealing sensitive data.
• MITM Attacks – Hackers intercept communications to steal data.
• DDoS Attacks – Overloading systems to disrupt operations.
• Brute Force Attacks – Guessing passwords through trial-and-error.
• SQL Injection – Injecting malicious SQL scripts to access databases.
• DNS Attacks – Redirecting users to malicious sites by exploiting DNS flaws.

Conclusion

Cybersecurity is essential in today’s digital world to protect personal, corporate, and government data from cyber threats. Strong security measures, continuous updates, and user awareness are crucial to mitigating risks.
