Mobile teleworking some solutions and information security aspects

Mobile teleworking is carried out by secure access to a company's local area network (LAN) or to a server via public networks. It can be realized by using virtual private network (VPN) technology based on the Internet protocol (IP). Another possibility is the direct access to a LAN using the public networks GSM and Euro-ISDN. These two solutions are described. Security and operational aspects are also considered. It is pointed out that the solution based on hardware encryption devices, guarantees a very high level of security.
