"Essential's required for computer security "

Computer security, or cybersecurity, involves protecting systems, networks, and data from unauthorized access, attacks, or damage. It encompasses various practices such as network security, application security, and endpoint protection, focusing on safeguarding data integrity, confidentiality, and availability. Key threats include malware, phishing, and unauthorized access, while preventive measures involve encryption, strong authentication methods, regular software updates, and user education. Effective cybersecurity also requires robust incident response plans and security protocols to mitigate risks and recover from potential breaches, ensuring overall digital safety and privacy.
