Internet security is a branch of computer security specifically related to not only Internet, often involving browser security and theWorld Wide Web^{[citation needed]}, but also network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet.^[1] The Internet represents an insecure channelfor exchanging information, which leads to a high risk of intrusion or fraud, such as phishing,^[2] online viruses, trojans, worms and more.
Many methods are used to protect the transfer of data, including encryption and from-the-ground-up engineering. The current focus is on prevention as much as on real time protection against well known and new threats.^[3]
