2. How Cyber Security Works?

Cyber security works by employing a range of strategies, technologies, and practices to protect digital systems, networks, and data from unauthorized access, attacks, and vulnerabilities. It involves a multi-layered approach that combines preventive, detective, and responsive measures to ensure the confidentiality, integrity, and availability of information

Preventive measures form the first line of defense in cyber security. These include implementing strong access controls, robust authentication mechanisms, and encryption protocols to protect data in transit and at rest. Firewalls, intrusion detection and prevention systems, and antivirus software are also used to safeguard networks and systems from malicious activities.

Detective measures involve monitoring and analyzing network traffic, system logs, and user behavior to identify potential security incidents or breaches. Intrusion detection systems, security information and event management (SIEM) tools, and log analysis techniques help in detecting and responding to suspicious activities, anomalies, or indicators of compromise.

Responsive measures are taken once a security incident or breach is detected. Incident response teams are responsible for investigating, containing, and mitigating the impact of the incident. They follow predefined protocols and procedures to minimize damage, restore services, and recover affected systems.

Cyber security also involves regular vulnerability assessments and penetration testing to identify weaknesses in systems and networks. By conducting these tests, organizations can proactively address vulnerabilities and apply necessary patches or updates.

Employee training and awareness programs play a critical role in cyber security. Educating users about safe online practices, phishing attacks, and social engineering techniques helps in reducing the human factor as a vulnerability.

Cyber security involves staying updated with the latest security threats, vulnerabilities, and emerging technologies. Security professionals continuously monitor threat intelligence sources, participate in information sharing communities, and collaborate with industry peers to stay ahead of cyber threats.

3. Scope of Cyber Security

The scope of cybersecurity is rapidly expanding in response to the evolving digital landscape and the increasing frequency and sophistication of cyber threats. Cybersecurity encompasses a broad range of practices, technologies, and strategies aimed at protecting computer systems, networks, and data from unauthorized access, malicious attacks, and data breaches.
