Cybersecurity refers to the practice of protecting computer systems and networks from digital attacks, unauthorized access, and damage to hardware, software, or electronic data. It involves implementing various measures and technologies to ensure the confidentiality, integrity, and availability of information.
Cybersecurity is important because as technology advances, so do the threats and risks associated with online activities. Cybercriminals can exploit vulnerabilities in computer systems and networks to gain unauthorized access, steal sensitive information, disrupt operations, and cause harm to individuals, organizations, and even nations.
The scope of cybersecurity includes various areas such as network security, application security, data security, cloud security, and endpoint security. It involves implementation of firewalls, antivirus software, encryption techniques, intrusion detection/prevention systems, and security awareness training for employees.
Moreover, cybersecurity includes proactive measures like implementing patch management, conducting regular vulnerability assessments and penetration testing, developing incident response plans, and creating backups of important data.
