Cybersecurity is the practice of protecting internet-connected systems, including hardware, software, and data, from cyber threats. These threats can come in various forms, such as malicious software (malware), phishing attacks, hacking, social engineering, and more. With the increasing reliance on digital technology in both personal and professional spheres, cybersecurity has become a critical concern for individuals, businesses, governments, and organizations worldwide.

The primary goal of cybersecurity is to safeguard sensitive information, maintain the integrity of systems and data, and ensure the availability of resources.

This involves implementing a range of security measures, including but not limited to:

1. Firewalls and Intrusion Detection Systems (IDS): These technologies monitor and control incoming and outgoing network traffic to prevent unauthorized access and detect suspicious activities.

2. Encryption: Encryption transforms data into a format that can only be read or understood by authorized parties. It helps protect data confidentiality, even if it is intercepted by unauthorized users.

3. Access Control: Access control mechanisms restrict user access to resources based on predefined policies. This ensures that only authorized individuals or systems can access sensitive information or perform specific actions.
