Internet security is a branch of computer security specifically related to the Internet, often involving browser security but also network security on a more general level as it applies to other applications or operating systems on a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing. Different methods have been used to protect the transfer of data, including encryption and from-the-ground-up engineering.
Internet security is a catch-all term for a very broad issue covering security for transactions made over the Internet. Generally, Internet security encompasses browser security, the security of data entered through a Web form, and overall authentication and protection of data sent via Internet Protocol.
Internet security relies on specific resources and standards for protecting data that gets sent through the Internet. This includes various kinds of encryption such as Pretty Good Privacy (PGP). Other aspects of a secure Web setup includes firewalls, which block unwanted traffic, and anti-malware, anti-spyware and anti-virus programs that work from specific networks or devices to monitor Internet traffic for dangerous attachments.
Internet security is generally becoming a top priority for the businesses. Good Internet security protects financial details and much more of what is handled by a business or agency's servers and network hardware. Insufficient Internet security can threaten to collapse an e-commerce business or any other operation where data gets routed over the Web.
The Internet provides a wealth of information and services. Many activities in our daily lives now rely on the Internet, including various forms of communication, shopping, financial services, entertainment and many others. The growth in the use of the Internet, however, also presents certain risks. Just think about all the information you send over the Internet, such as personal messages, bank account information, photographs, etc.
As a typical Internet user, you have the reasonable expectation that your communications and transactions are private and secure. When you make a video call to a family member, you expect that nobody else is watching. When you buy something online with a credit card, you expect that nobody else can get access to your credit card details.
For the most part, the Internet is indeed private and secure, but there are a number of serious security risks. This lesson will review some of those security risks and provide some practical suggestions on how to address them.

In a nutshell, the term 'internet security' is used to describe software which protects your computer, the data on it and ultimately yourself, from being exploited online. 'Internet security' is usually a compilation of different types of security tools, such as antivirus, anti spam filters, firewalls and anti spyware software.
