The Importance Of Internet Security

1. What is Internet Security?

Internet Security is a type of computer security related to the internet. It is provided through the use of multiple other schemes. Such as browser security and network security. Many applications that run on a personal computer through the use of its operating systems may want to access the Internet for add-ons or to send out information about the system this can be with or without the administrators consent. Thus Internet Security changes how and when applications are run altogether. Its a broad spectrum covering all transactions made over the Internet. It provides overall autentication and protection of ones information or data sent over the internet. Without proper Internet Security the effects can be extremely

When a server and client communicate. It ensures that no third party may eavesdrop or tamper with any of the data being transferred. Transport Layer security is the successor to the Secure Sockets Layer.

1.1.2 Secure Sockets Layer picture

Seure Sockets Layer or SSL is a standard security option for establishing an encrypted link between a server and a client. Example a web server and a browser or mail server and mail client. Through SSL we are able to transfer personal details over the Internet without te fears of any other client having access to our data (eavesdropping). The data is not sentin plain text therefore it is much more secure through encryption. This encryption uses the public key and private key system. Each key is cryptographic, able to secure data in the presence of third parties.

Public Key - its available to everyone via a publicly made directory.

Private Key - remains confidential to its respective owner.

The pairs of keys are interrelated. Thus whatever is encrypted by a public key can only be decrypted by its corresponding private key. Public keys also generate a Digital signature. A digital signature is a mathematical scheme for demonstrated the authenticity of a digital message. Https is associated with a SSL-secured

The security token keys include built in mathematical computations and manipulate numbers based on the present time built into or set on the device. Every thirty seconds there is only a certain array of numbers possible (no specific order)which would be correct to validate in order to access the online account. The website that the user is logging into would be made aware of that devices' serial number and would know the computation and correct time built into the device to verify that the number given is indeed one of the handful of six-digit numbers that works in that given 30-60 second cycle. Every 30-60 seconds the device will produce a new random six digit number in order to validate and gain access to the
