Be very careful of such claims. While a proxy server may indeed include options for rudimentary filtering of certain communications, there have been several instances of serious security holes in low-cost, but popular, proxy software. For particular applications where the highest security is not necessary, a simple proxy server may function adequately for your needs. But if true Internet security is your goal, use firewalls in addition to, or possibly instead of, proxy servers. Encryption Regardless of the security deployed on the network, businesses on the Internet need to understand and utilize encryption technology for their sensitive business information.
Encryption is both the first and last line of Internet security.
It will preserve confidentiality for documents, data and other files even if the network security system is penetrated. Modern encryption technology is relatively easy to deploy and comparatively inexpensive. It has an added advantage of serving as a document integrity mechanism as well as maintaining security. Your business network is best protected against intrusion by technical means, but it is also protected by the law. Federal, and in many cases state, criminal statutes prohibit unauthorized access to individual computers or computer networks.
