Network Box White Paper: Securing Remote Workers
Source: Network Box
In the case of home workers, the employee must use a VPN. The three most commonly used today are PPTP, IPSEC and SSL. IPSEC and SSL are the most secure, because they can use the highest security encryption - AES 256. SSL VPNs are becoming popular as they are more robust and flexible. So, with the deployment of a VPN, the data can travel securely from the server in the office to the remote workstation. But when it gets to the workstation, it is unencrypted and can be written to the hard disk or to temporary files. When the user disconnects from the VPN, these files remain on the remote workstation unencrypted unless carefully purged by the user.
