Cyber security refers to protecting networks, devices, programs and data from attacks, damage or unauthorized access. It is important as more people and infrastructure rely on online systems. Major cyber security threats include viruses, malware, trojan horses, hackers and password cracking. To improve cyber security, strong passwords, antivirus software, firewalls and keeping systems updated can help prevent hacking and malware infections. Cyber security is a shared responsibility and India has seen increasing cyber crimes like ransomware attacks and an online bank robbery where over 94 crore rupees were stolen.
