Silicom 100G 旁路交換器Bypass Switch/TAP
Silicom 100G 旁路交換器Bypass Switch/TAP
Inline資安設備,如NGFW、IPS、WAF、DDoS、SSL、DPI,是企業避免遭受駭客或蠕蟲入侵的守門神,需要對每個封包深度檢測,確認安全無虞後,才能讓封包通過。因此繁複的工作需要大量消耗設備的CPU效能,並且軟硬體都必須有良好的搭配,而資安設備的效能也與阻擋規則的種類與多寡息息相關,能夠處理的流量並非等同於介面速度,因此難免偶而的當機或更新軟體初期系統不穩定等,導致對外網路斷線,反而造成企業立即的災難,甚至營收的損失。旁路交換器的功能,能讓這種斷線的風險,降到最低。
旁路交換器(Bypass Switch)的功用,是用來免除透通模式(Inline)的資安監控設備或頻寬管理器,所引起的網路斷線疑慮,從防護的效用來看,一般可分為三種等級:
- 普通級:Inline主機與自身斷電bypass
- 進階級:普通級功能加上 Inline主機當機、斷線bypass
- 最高級:進階級功能加上 旁路交換器自身當機bypass
IS100 100G 旁路交換器(Bypass Switch),皆屬於最高等級的防護力,具備主動與被動式旁路能力,能保護網路,不讓監控設備因維護、當機或斷電而導致網路中斷。除了可發送監控用的心跳封包(Heartbeat),監控資安主機進行旁路切換之外,也監控自己的健康狀態,自己當機或斷電也能進行旁路切換,而不會成為網路的故障點。
一般用戶的迷思,認為內聯(Inline)設備只要具備Bypass功能的網卡,發生故障時就不會造成網路中斷了,但殊不知IPS、WAF、DAM、頻寬管理器等內聯(Inline)模式設備故障,最常造成網路斷線的原因就是...當機,或者已經處於流量處理速度很慢,但卻又沒有斷線的"半死"狀態,造成用戶聯外失敗的問題;即使用了HA架構,但這種狀況發生時,卻仍需要手動切斷故障的內聯設備,才能讓全部流量順利進入HA備援機制的第二台監控設備中。此刻內聯設備內建的bypass網卡的作用,只是在設備切斷電源後,暫時讓網路流量可以通過。但如此一來,完全達不到自動化斷線防護目的,仍需要耗費人力,處理斷線的問題,且是在造成網路down time一段時間後,才能解決問題,因此越來越多用戶開始重視斷線防護等級的差異,並願意投資更有效的斷線防護方案。
Silicom IS100智慧旁路交換機採用1U標準機箱,擁有兩個模組的擴充空間;每個100G模組支援一對旁路端口(1 segment)。
再介面選擇上,IS100智慧旁路交換機除了支援單模光纖(100GBase-LR4),也支援多模光纖(100GBase-SR4, 100GBase-SR10),每個旁路模組提供兩個MPO/LC規格的網路端口連接上下端網路,以及兩個QSFP28端口連接Inline模式的資安設備。
Silicom IS100智慧旁路交換機(Intelligent Bypass Switch)支援四種旁路模式:正常內聯(Normal inline)、旁路(Bypass)、分流(TAP)與斷線(Linkdrop)等模式。
- 在正常內聯模式下(Normal),IS100引導網路流量至所連接的內聯網路設備。
- 在旁路模式中(Bypass),IS100不會將流量引導到所連接的網絡監控設備(Inline appliance),而將流量直接導回到網絡中。
- 在分流模式(TAP)中,流量直接透通NET埠,但被複製到MON埠,進入NET0端口的流量會被複製到MON0端口,進入NET1端口的流量被複製到MON1端口,網路實際流量在NET0與NET1之間傳送,不會導入連接MON0與MON1的網路設備,讓設備不會影響網路,卻又能有測試流量,以利工程師偵錯。
- 在斷線模式(Linkdrop),IS100偵測到"當機"的內聯設備,則自動關閉網絡端口(NET0, NET1)的連接讓網路中斷,讓流量可以順利導入仍在HA模式中的正常監控設備,才能真正達到全時自動化監控的效用。
IS100 bypass模組可產生心跳封包(Heartbeat),心跳封包隨著網路流量到內聯式的網路監控設備的網路端口,讓心跳封包從網路端口進入設備內部,並與其他網路流量傳輸到其他端口(橋接心跳封包),送出心跳封包。IS40 bypass模組在預設時間內檢測到返回的心跳封包,則保持內聯模式。
當IS00 bypass模組未從內聯設備端檢測到返回的心跳封包(heartbeat packet) ,則依據預先的設定,IS00自動會被切換成旁路(Bypass)、複製分流(TAP)或鏈路斷線(Linkdrop)模式。當內聯(Inline)監控網絡設備恢復正常並讓心跳封包在預設時間內返回bypass模組,IS100偵測到返回心跳封包,則恢復成正常內聯模式。通常,bypass模式會在內聯設備電源故障、鏈路故障、內聯軟體應用程序系統當機,或使用者要求時啟動。
IS100包含雙重旁路安全架構。Silicom雙重旁路安全架構基於兩個旁路路由電路:一個為主動旁路電路和被動旁路電路。如果內部偵測到主動旁路路由電路發生故障時,則啟動被動旁路路由。因此,IS100不僅監控內聯設備的健康狀態,也監控自我的旁路功能是否正常,讓用戶多一層保障。
- 簡單的CLI指令設定介面,經由序列埠console、 Telnet 或 SSH.
- 網頁圖形GUI管理介面
- SNMP Write網管自動寫入
IS100是一款1U主機系統,最多可支援兩個100G bypass模組,主機包含兩個備援110 - 220 V AC電源或兩個備援-48直流電源。
