           What is cyber security  ?

Ans-Cybersecurity is the practice of protecting computer systems, networks, devices, and data from cyberattacks, unauthorized access, or damage. It involves a variety of technologies, processes, and measures designed to safeguard information and systems from threats.

Key Areas of Cybersecurity:

1. Network Security: Protecting computer networks from intrusions, whether targeted attacks or opportunistic malware.
2. Application Security: Ensuring software and apps are secure from vulnerabilities during development and deployment.
3. Information Security: Protecting the confidentiality, integrity, and availability of data.
4. Endpoint Security: Securing devices like laptops, smartphones, and IoT devices connected to the network.
5. Cloud Security: Safeguarding data and services hosted in cloud environments.
6. Identity and Access Management (IAM): Ensuring that only authorized users have access to specific resources.
7. Disaster Recovery and Business Continuity: Planning for resilience in the event of a cyberattack, ensuring minimal disruption.
8. Operational Security (OpSec): Protecting the processes and decisions involved in managing sensitive data.

Common Cybersecurity Threats:

• Malware: Malicious software, including viruses, ransomware, and spyware.
• Phishing: Deceptive emails or messages designed to trick individuals into revealing sensitive information.
• Denial of Service (DoS) Attacks: Overloading systems to make them unavailable.
• Man-in-the-Middle (MITM) Attacks: Intercepting communications between two parties.
• Social Engineering: Manipulating individuals to gain access to systems or data.
• Zero-Day Exploits: Attacks on vulnerabilities that are not yet known to the software provider.
