What is "internet security"?
Communication on the internet is constantly under the threat of attack from such sources as unauthorized access and message modifications. Internet security is the avoidance of unauthorized access and/or damage to computer systems via internet access.
What is the need for internet security?
There is a need to protect your PC from viruses and spyware that can delete files or corrupt your computer. In today’s complex and ever changing world, the need for Internet security increased dramatically, due to a variety of fraudulent activities related to password management, such as identity theft, phishing attacks and so on. This is due to the fact that most people can only remember a handful of passwords and therefore use the same combination of username and password for all protected web access. This leads, however, to low system security.
How to counter internet security threats?
Even if your computer isn't used for anything critical you need to run security software such as an antivirus and a firewall. These programs will keep your computer "hidden" from prying eyes over the internet, as well as protected from viruses and other malware that can be spread through email or other methods. You also need to make sure you're familiar with the different types of security threats so you can deal with them if they ever come up.
