Additionally, after transition to an electronic-based system, confidentiality of information and authentication of system users will be key requirements. Access to information should be protected using the most powerful electronic techniques available and economically feasible. Information Security Information security requires that both the system storing the information and the media conveying the information provide appropriate protection of the information content and access to it. Information residing on a networked computer system cannot be guaranteed to remain secure. No technology is able to provide such a guarantee.
Technology can only provide a probability of security of information.
This is of course subject to the system that incorporates the technology being designed appropriately. Sensitive information held by governments and military organizations is usually protected by high grade, hardware-based encryption products. So too, is financial information held and transferred by banks. Software techniques provide a level of protection, but will never be as secure as a system whose boundaries are guarded by hardware access and encryption products. The most common forms of communication are voice and facsimile.
