Bluetooth
Bluetooth is a short-range wireless information transfer technology aimed
at replacing cables between mobile phones and peripheral devices, among
others. Bluetooth-equipped devices at a close proximity to each other
can establish a wireless connection between them. For example, a mobile
phone’s button headset can operate wirelessly via Bluetooth.
IMEI code
The IMEI code is the mobile phone’s serial number. You get the code
(often with 15 digits) on the display by pressing *#06#. Normally, the
IMEI code is also given on a white sticker located under the phone’s
battery. The owner of the mobile phone can prevent the use of his/her
mobile phone by reporting the phone’s IMEI code to the operator.
PIN code request
The PIN (Personal Identification Number) code (4–8 digits) protects
the SIM card against unauthorised use. The PIN code normally comes with
the SIM card. If a wrong PIN code is given three consecutive times, the
mobile phone locks itself.
SIM card
A mobile phone subscriber always receives a personal SIM (Subscriber Identity
Module) card. It is a chip card, which has an embedded computer with an
operating system and applications on it. The SIM card is used for identifying
and locating the subscriber of the mobile phone subscription. If the mobile
phone has been switched off, based on the SIM card, the location where
the phone was when switched off can be identified. The use and content
of the card can be protected by using a PIN code.
Trojans
A Trojan is a malicious software disguised as an innocent game or other useful program. Usually, a trojan performs a simple task, which activates a mobile phone virus or other vulnerability. It may also destroy the mobile phone details. A trojan will not spread from device to device by itself.

Virus
A virus is a malicious software which infects software or a document by spreading via it to another target.
Wireless Local Area Network, WLAN
A wireless local area network is a local area network, e.g., in an
office, at an airport, or in a hotel, to which the devices in that
area are wirelessly connected. The network is based on a standardised
WLAN technology.
Several state-of-the-art terminals, e.g., laptop computers, handheld
PCs and mobile phones, include the possibility for WLAN. However,
the WLAN is connected to a fixed network, not to a mobile phone network.
Therefore, the security guidelines for the use of a fixed network
should be complied with also in WLAN connections.
The
Finnish Communications Regulatory Authority’s (FICORA’s)
guidelines on wireless local area network (WLAN) security.
Worm
A worm is software containing malicious characteristics that spreads via e-mail or networks. |
