碩士 === 逢甲大學 === 資訊工程所 === 98 === Protective measures for server invasions should not solely focus on events before an invasion occur. Recording and monitoring successful server invasions with endless streams of security mechanisms should be employed attentively to reduce the loss of data due to successful intrusion attacks on most of system. Overlooking this will inevitably lead to detrimental data loss and stray away from the key issue of limiting the time an unauthorized user has on the system. The thesis presents an implementation of embedded system technology developed in a host control module group in which the entire server achieves coordinated group allocation of resources combined with a larger number of group hosts designed to meet demand. The proposed secure server switching system (4S) uses server load balancing to prevent system failures, errors, and interruptions, accompanied with the ever so important theory of fault-tolerance for grace degradation purposes. The prototype described in this study is comprised of 8 servers with 2 hosts housing those servers to meet service demand .In addition, these virtual machines (VMs) to host relationship allows 4S to recover from attacks rapidly by allowing the improvised service on server the ability of being back to normal in a very short time.
