After you have a firm set of requirements, focus on design. This determines how you\'re going to satisfy requirements with least cost. The design should fully describe what components and configurations are necessary to satisfy the requirements. Through the design process, produce a design specification that highlights the chosen design elements and provides a diagram indicating the placement of access points within the facility. For smaller networks, you may only spend a day or so designing the solution. In larger implementations, it may take weeks or months to fully define enough technical detail before moving forward with the acquisition of hardware and installation services. These larger projects will likely benefit from simulation, prototyping, or pilot testing as part of the design to ensure you\'ve made the right choices and the requirements are fully realizable.

Keys in the Clear
 In a typical SSL installation, the server maintains credentials so that clients can authenticate the server. In addition to presenting a certificate at connection time, the server also maintains a private key, which is necessary for establishing that the server presenting a certificate is actually presenting its own certificate. Cryptographic-acceleration cards will generally store the key in hardware, making it unavailable to the actual computer.
