Network Name (SSID) An SSID (service set identifier) is the name of a wireless local area network (WLAN). All wireless devices wishing to connect must use the same SSID in order to communicate with each other.

Security KeySecurity keys are used to exchange messages between devices. These are commonly encrypted with WEP (Wired Equivalent Privacy). This is set through the network router setup wizard. It is a sequence of hex digits chosen by a network administrator and assists with securing the network connection. As with all technology WEP has been superseded by WPA (Wi-Fi Protected Access) and WPA2 which provide greater security.

StorageYou can store data on...CD/DVD (Optical Disk)Memory CardsExternal Hard DrivesSolid State DrivesUSB/Memory SticksCloud StorageArchivingAn archive tends to be the backup of data for long-term storage. The user does not expect to retrieve this data but it is there in case they have to. In this storage the medium has to have a long shelf life.

Data Protection ActThe Data Protection Act (DPA)The Data Protection Act 1998 sets out to protect the privacy of personal information.

Possible Legal Implications if any of the 8 rules are breachedFor serious breaches organisations can be made to pay up to 500000

The organisation can be prosecuted/fined/sued if the data is stolen and not held securelyData held must be protected from lost, so if the data is lost an offence has occurred. Furthermore the organisation will need to tell the person whose data it was.
