The technology involved is very secure. Crackers who wish to access your data without compromising your certificate files and/or passwords will find the task to be very difficult. The VPN will automatically generate new encryption keys every hour, so the cracker will have to record a copy of all your traffic throughout a period of one hour - then let a super computer work for a significant period of time to crack the encryption for that hour. Your traffic during the next hour will have to be cracked separately. It is much easier for criminals to use more direct means to get access to your information.
Statistically, the main threats to your VPN security are
- Unauthorized changes made to your workstations' network configuration,
- Certificate files that fall into the wrong hands and
- Passwords that fall into the wrong hands.
To ensure the security of your network:
- Do not allow unauthorized people (such as your children,) to install or remove software or hardware from your secured workstations,
- Find out about and respect the security procedures related to your VPN. In particular, make sure you quickly report any possible compromise of your certificate files or your passwords so that the associated privileges can be revoked and replacement certificates issued.
