Checkpoint is promoting its Virtual Private Network (VPN) strategy, which combines firewall software with encryption technology and access control, so that data transmissions are secured. Bennett added that VPN technology will lead to the emergence...
The second method is public key (PK) cryptography, which uses both a private and a public key. This is the fastest method, but transmitting the secret key to the recipient in the first place is not secure," said Walker.
Finally, for an even safer security set-up WLAN users should consider creating a IPsec VPN. In this configuration each device (client and network) is fully authenticated and communicates via an encrypted VPN 'tunnel'.
And, drawing a distinction between existing wi-fi-enabled phones, which can use a soft Skype client, and phones designed around Skype, Shrimpton said the latter would "undoubtedly give a more seamless user experience".
One approach is to use an IPSec (internet protocol security) VPN but the processing overhead can impact on the quality of the voice service. To prevent this we create a VPN tunnel between the user and the VoIP servers.
It's those risks at the more far-reaching end of the scale which likely account for the greatest consideration and going through appropriate due diligence is no mean feat. Naturally, the method needs to be repeatable because threats will change and...
