網路安全測試平台(Testbed@TWISC, T@T)整合美國Utah大學所授權的Emulab軟體、國產硬體以及自行研發設計的軟體與韌體，可克服時間與空間的限制，利用簡單的Web介面，提供國內資訊安全研究與實驗所需的隔離性、封閉性、可紀錄性、可控制性與可儲存性之完整環境。
Testbed@TWISC目前擁有1台Boss Server、1台OPS Server、1台Control Switch、3台Experiment Switch、155台實驗節點、21台電源控制器、3台SerialPort Controller、1組環境監控設備等設備，待98年12月底將更新至198台實驗節點供使用。網路設備的傳輸，至少一半以上採以10/100/1000Mbit傳輸，提供給需做相關網路實驗之使用者選用
Testbed@TWISC所有實驗節點皆為真實的實體機器，並非以Virturl Machine模擬出來的機器。每一台實驗節點皆可執行任意軟體、simulated router、traffic-shaping或是traffic generators。當實驗建立好後，每位使用者可獨自控制所有資源，包含擁有root權限。我們提供的預設作業系統為Fedora Core 6。每一台實驗節點預設的設定包含同一個Project成員的帳號存取、root權限、DNS服務。使用者除了上述提及的可任意安裝軟體外，亦可根據實驗需求，隨時更換網路拓樸。

Emulab is a universally available time- and space-shared network emulator which achieves new levels of ease of use. Several hundred PCs in racks, combined with secure, user-friendly web-based tools, and driven by ns-compatible scripts or a Java GUI, allow you to remotely configure and control machines and links down to the hardware level. Packet loss, latency, bandwidth, queue sizes-all can be user-defined. Even the OS disk contents can be fully and securely replaced with custom images by any experimenter; Emulab can load ten or a hundred disks in less than two minutes. Emulab strives to preserve the control and ease of use of simulation, without sacrificing the realism of emulation and live network experimentation.
