    • 當今網路資訊安全的架構趨勢已由防堵(Prevention)模式轉化為偵測與立即反應 (Detection & Response) 模式

    • 此種資安運作模式必須仰賴一套整合式的資安聯結架構, 以供各種不同資安設備的佈建與擴充

    • GigaSECURE是業界首套資安訊息派送平台 (Security Delivery Platform) , 此架構將轉化現有資安服務建置的方式 – 使資安設備更有防治效益, 更自動化, 更降低成本

    應用四 : 大幅減少記錄容量

    選擇性封包裁切

    • 去除重覆封包

    • 單一session流量經由數個網路結點, 會產生多個相同而重覆的封包

    • De-Dup功能可辦識相同session流量而將重覆封包只留取一筆, 而可減少33~75%的封包量

    去除重覆封包

    • 封包裁切

    • 對不同屬性流量可裁切不同長度的封包, 可以減少側錄或大數據設備的容量

    • 平均網路流量封包長度約為800Byte, 如果依需要裁切為平均200Byte, 則可節省80%流量

    • 該科技大學因承辦技專校院招生委員會聯合會相關業務。因應教育部政策,資安等級提升為A級

    • 評估峰值流量於一年內將增加為6Gbps至8Gbps

    • 現有APT、WAF不是無對應流量之型號或是無法負荷之預算金額

    • POC測試設備時無法克服 – 核心交換器因Mirror Port過多無法負荷

    – 某些測試設備必須Inline,上線時調整線路造成斷線

    – 測試設備異常無法即時拔除

    • 設備採購成本降低 – 緩衝資安設備HA一次到位預算壓力

    – 使用Map Filter 依照條件決定流量路徑。8Gb流量也能用4Gb設備,如: • IP Dst 非Server Farm 不通過WAF設備

    • 非SSL封包不通過SSL解密設備

    • 非關鍵業務網段不通過APT設備

    • 高度彈性 – 可控制介面,依需求彈性切換使用模式不浪費

    – 依政策需求可調整個別設備故障政策(Fail Open、Fail Close)

    – 設備測試、維護及升級不斷線,提升業務持續運作成效
