Cyber security is the practice of protecting computers, servers, and networks from cyber attacks. It is a growing concern as the use of the internet and connected devices has increased in recent years, and cyber attacks have become more sophisticated.
There are many different types of cyber attacks, including malware, phishing, and ransomware. Phishing is a type of scam in which attackers send fake emails or messages in an attempt to trick people into revealing sensitive information, such as passwords or bank account numbers. Ransomware is a type of malware that encrypts a victim’s files, making them inaccessible until a ransom is paid to the attacker to restore access.
To protect against cyber attacks, it is important to use strong passwords and to update them regularly. It is also a good idea to use two-factor authentication, which requires an additional piece of information, such as a code sent to a phone, in addition to a password to log in. It is also important to keep software and security systems up to date, as attackers often target vulnerabilities in outdated systems.
In addition to protecting individual devices, it is important to protect networks as well.this is protect through the use of firewalls and other security systems. It is also important to have policies in place to ensure that employees are aware of the risks and are taking appropriate measures to protect company networks.
