- Digital systems
from unauthorized access, attacks, or damage.
The main goal of cybersecurity is to keep information secure and prevent cybercriminals from stealing, modifying, or destroying data.
Cybersecurity includes multiple areas such as:
- Network Security
- Information Security
- Application Security
- Cloud Security
- Ethical Hacking
- Digital Forensics
Why Cybersecurity is Important
Technology has become a major part of everyday life.
People use digital systems for:
- Banking
- Online shopping
- Education
- Communication
- Government services
- Healthcare
As a result, huge amounts of personal and financial data are stored online.
Without proper security, hackers can:
- Steal sensitive information
- Lock systems using ransomware
- Leak private data
- Damage business operations
Cybersecurity helps reduce these risks and keeps systems safe.
Common Types of Cyber Attacks
Understanding cyber threats is an important part of cybersecurity.
1. Phishing Attacks
Phishing is a fake attempt to steal sensitive information.
Attackers may send:

to trick users into revealing passwords or bank details.
2. Malware
Malware refers to malicious software designed to damage systems.
Examples include:
- Viruses
- Worms
- Trojans
- Spyware
Malware can steal data or disrupt operations.
3. Ransomware
Ransomware locks files or systems and demands money for recovery.
Many companies and hospitals have suffered major losses because of ransomware attacks.
4. Password Attacks
Weak passwords are one of the biggest security risks.
Hackers use:
- Brute force attacks
- Credential leaks
- Password guessing
to gain unauthorized access.
5. DDoS Attacks
Distributed Denial of Service attacks overload servers with massive traffic, causing websites or applications to stop working.
