Security

=Security= by Mrs North

Security refers to the protection of hardware, software, machines and networks from unauthorized access. Security measures include restricted access to machines and networks for certain employees or to prevent access by hackers. The degree of security of information systems largely determines societies confidence in the information contained in the systems.
 * ITGS Definition**

Internet Banking - a new security system was put in place this summer in the UK by HSBC to enable a more secure access to personal banking online. One of the biggest issues to overcome in e-commerce (business over the internet) was ensuring systems / websites have enough security in place to prevent unauthorised users gaining access to bank details, etc.
 * Examples:**

The new security put in place by HSBC now uses a //two-factor authentication.// Bank users are now required to use a key fob in order to access their banking online.

A key fob is a type of [|security token] : a small hardware device with built-in [|authentication] mechanisms. Just as the keys held on an ordinary real-world key chain or fob control access to the owner's home or car, the mechanisms in the key fob control access to network services and information. The key fob (and similar devices, such as [|smart card] s) provide //two-factor authentication//: the user has a personal identification number ( [|PIN] ), which authenticates them as the device's owner; after the user correctly enters their PIN, the device displays a number which allows them to log on to the network. Because a key fob is a physical object, it is easy for the owner to know if it has been stolen. In comparison, a password can be stolen (or guessed) and used for an extended period before -- if ever -- the theft is detected. This definition was taken from: Fob Key - Whatis.com
