Importance of Cyber Security in Internet Age.
The modern-day internet is a very important part of human civilization.The use of the Internet is seen in every sector like professional work, education sectors, the entertainment world, shopping, lifestyle, online business, monitory transaction, and many.
To maintain everything properly it is important to protect devices, which are responsible for connecting to the internet (computer, laptop, smartphones).
Cyber Security is the technique to protect users' digital components like data, networks, the computer system (files), online financial information from unauthorized access by unethical hackers or crackers.
Term Cyber means internet-related resources or information and security means protecting techniques, so cybersecurity stands for protecting digital resources on a person or an organization.
Crackers or illegal hackers use different techniques to break into the system of a person or an organization to gain unauthorized access to data or information. Their main motive is tampering with data or monitory gain.
Here are few ways to get access to a system illegally
Virus based attacks
A virus is a destructive computer program. spyware,malware, trojan, adware, worms are types of virus attacks that may occur while downloading content unauthorized websites from the internet.
Phishing attacks
In a phishing attack, hackers send attractive Email offers, duplicate links (of known websites), or any suspicious link ( with an embedded virus in it) send to users to still their data, personal info, login, or financial credential.
