what is cyber security

Cybersecurity is the practice of protecting computer systems, networks, and data from unauthorized access, theft, damage, or disruption. It involves the use of technologies, processes, and policies to secure systems and data from cyber attacks, which can take the form of malware, phishing, social engineering, and other malicious activities.

The goal of cybersecurity is to ensure the confidentiality, integrity, and availability of sensitive information and systems. This is important for organizations and individuals alike, as cyber attacks can result in the loss of sensitive data, financial losses, reputational damage, and other negative outcomes.

Cybersecurity encompasses a wide range of technologies and practices, including:

• Firewalls: Devices that control incoming and outgoing network traffic based on pre-defined security rules.

• Encryption: The conversion of sensitive data into an unreadable form that can only be decrypted by authorized users.

• Antivirus software: Programs that detect and remove malicious software from computer systems.

• Access control: The process of granting or denying access to resources based on predefined policies.

• Network security: The protection of networked systems and data from unauthorized access or disruption.

• Incident response: The process of preparing for and responding to cyber attacks, including the identification of the attack, containment of the damage, and recovery of systems and data.

Cybersecurity is an ever-evolving field, and it is important for organizations and individuals to stay informed about the latest threats and best practices in order to effectively protect their systems and data from cyber attacks.
