Virtual Private Networking (VPN)
|
Information sent over the Internet is not secure. Data that is sent across the Internet without being encrypted (scrambled) can be read by just about anyone. Most people do not realize that sending an email ensures no more privacy than sending a postcard.
For a secure network connection, without the need to individually encrypt messages on an item-by-item basis, a high security encrypted V.P.N. (Virtual Private Network) system is required.
Network Box supports different kinds of VPN tunneling technologies:
Network Box also supports different kinds of encryption technologies, such as 3DES, AES 128 and AES 256 to name the most secure.
There is no limit on the number of licenses for VPN connections, on any model of Network Box. The only limit may be the physical capabilities of the hardware.
A VPN connection is treated as a virtual interface. The connection is terminated on the box itself, and routing/firewall/IDP rules and filters are applied to it as they can be applied to any physical interface.
IPSEC uses 3DES (192bit) encryption and 2048bit signatures, or AES 128 or AES 256, with support for AH, ESP and IKE (dynamic keying). Both shared secret and public-key exchange are included. It supports point-to-point, LAN-to-LAN and point-to-LAN topology, in both static and road warrior configurations. Dynamic IP addressing is also supported.
SSL uses AES 256 (Advanced Encryption Standard). It is the newest addition to our list of supported VPN, and it is a true VPN tunnel, not an SSL gateway. This VPN is optimal for roaming users because it does not have the NAT traversal issues commonly found in some IPSEC clients. It is by far the most secure because of the AES 256 encryption. The client necessary for the connection is free of charge and supports Windows, Linux and MAC. Versions for PDA are being developed.
SSL VPN also supports site to site connections and can be coupled with dynamic routing to create tunnels with failover connections between your many locations.
AES (Advanced Encryption Standard) is the successor to DES:
- In January 1997 the AES initiative was announced and in September 1997 the public was invited to propose suitable block ciphers as candidates for the AES. The AES algorithm was selected in October 2001 and the standard was published in November 2002.
- This project was intended to create a cipher that will remain secure well into this century.
- AES supports key sizes of 128 bits, 192 bits, and 256 bits, in contrast to the 56-bit keys offered by DES and 168 of 3DES.
- Over time, many implementations are expected to upgrade to AES, both because it offers a 128-bit or 256-bit key size, and because it is a federal standard.

POP3 and IMAP4 accounts are fully protected by the Network Box solution as soon as they are activated on the LAN. That is it - no setup required. Most systems cannot offer this type of protection at all. Automatic POP3 and IMAP4 email protection also allows sites which do not host their own email systems, to be protected by the Network Box. The outsourcing of email management is common, yet many traditional anti-virus email gateways cannot work with such a configuration, as they only support the SMTP protocol directly.
