What Is Cyber security?

- Cybersecurity is the practice of protecting systems, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It's essentially a digital defense system against a wide range of threats, including:

⦁ Hackers: 

  - Criminals who break into computer systems to steal data, install malware, or disrupt operations.

⦁ Malware: 

- Malicious software, such as viruses, worms, and ransomware, that can damage or steal data.

⦁ Phishing: 

- Deceptive emails or websites designed to trick users into revealing personal information or clicking on malicious links.

⦁ Denial-of-service (DoS) attacks: 

- Attempts to overwhelm a website or server with traffic, making it unavailable to legitimate users.

⦁ Why is Cyber Security Important?

- Cybersecurity is crucial because it safeguards all types of data against theft and loss. Sensitive data, protected health information (PHI), personally identifiable information (PII), intellectual property, personal information, data, and government and business information systems are all included. Many websites would be practically impossible to enjoy if cyber security specialists did not work ceaselessly to prevent denial-of-service attacks.
