¶ … Sign-On Solutions
In any business computing environment, a business must often make a tradeoff between security and ease of use. Allowing end users access to all company systems can create a security nightmare. At the same time, restricting access by requiring separate sign-ins for each system can be time consuming, frustrating, and ultimately expensive and difficult to maintain. Multiple usernames and passwords place a heavy burden on users who must remember these, and on administration that must reset and maintain passwords and multiple authentication lists.
Single Sign-On Solutions
One common solution to the problem of balancing security and convenience is the single sign-on solution. A single sign-on solution simply refers to the ability of a user to sign onto multiple applications using a single password. This can occur in a number of scenarios, including business intranets and Internet applications. Security in this situation is maintained by creating a strong username and password combination. The company's computer system then uses this combination to allow this authentication to allow access to all...
Small companies often run on a small number of platforms, thus making the use of a single sign on solution relatively easy. Further, these companies have fewer employees, thus potentially reducing security risks for single sign on. In a larger corporate environment, a company may use tens of different systems. This often makes access using a single sign-on solution extremely difficult. As such, some systems often must be excluded from a single sigh-on solution (Tervo).
Types of Solutions
There are a number of single sign-on solutions available, beyond the simple username and password model. Smart cards and bio-identification systems offer more security are new technologies that can be effectively used in a single sign-on situation. Bio-identification can include voice, face, fingerprint, or iris pattern recognition (Jones).
Cost is an important factor in many single sign-on solutions. This is especially the…

Additionally the patient site is monitored through use of a camera. The software that has been developed is used
Target population is single parents and low-income parents in Sacramento County and Northern California. The goals are to emphasize the benefits that could be derived from raising children in two -parents households compared to a single parent home.

Again, it is not simply good enough to have a policy that addresses the need for a broad, systematic outline of changes to the telecommunications network, such as is the case with Coach, Inc. But rather, it is imperative this policy address both the broad policy issues (strategies) and the daily integrations of this new policies within various aspects of the organization (tactical)(MILLER 2003).
