13 SPAM的基本運作方式 1.Spammer取得你的Email地址: 使用 Web Spider或 Troller / Crawler
購買郵件名單(mailing list) 進行字典攻擊取得名單 Embedded Web-Beacons 2.Spammer 寄出全球百萬封垃圾信 使用『open proxies』 或暑『open relays』 使用錯誤的主旨和身份識別 同時從多個位址寄出垃圾信 DO IT AGAIN – Some Work Only 15 Hrs Month 4.部份垃圾郵件傳送至使用者的信箱中 SPAMMER低成本，賺大錢 3.大部份的ISP和企業嘗試拒絕垃圾信 利用過濾SPAM軟體 安全清單和拒絕名單 Challenge和 Response 成功地減少 80%以上的SPAM

14 智慧型垃圾郵件過濾器的作業模式 1 2 3 4 成千上萬個Hotmail 用戶自願和微軟公司對SPAM作鬥爭
正常的信件 1 成千上萬個Hotmail 用戶自願和微軟公司對SPAM作鬥爭 2 Feedback Loop Servers 這些用戶提供服務中心數百萬封垃圾信做處理 3 011001 微軟的智慧垃圾信過濾器 這些信件教導智慧過濾器如何去過濾這些信件 依據世界主要的信箱提供業者的垃圾信樣本 超過 100K以上的垃圾信特性作為判斷是否為垃圾信 4 在信件到達個人收件匣之前,智慧型郵件過濾器針對每一封信的『垃圾信可能性』評等(1~9等級)

34 AD結構規劃(三)

35 AD結構規劃(四) Inter-Org tools Free/Busy &Public Folders MIIS 2003

36 GC與DC之規劃考量(一) Domain Naming Master(網域命名操作主機)
最好與GC Server 在同一台電腦 Infrastructure Master(基礎結構主機) 儘量不與GC Server 在同台電腦 儘量與GC 伺服器在同一個站台 每個 Domain 至少應有兩台DC 負載平衡 容錯系統 Exchange Server數量:GC數量=4:1

37 GC與DC之規劃考量(二) 實體網路拓樸 使用ADSIZER工具 若考量Exchange Server每個Site至少應有兩台GC

38 講座大綱 Exchange 2003的效益分析 Exchange 2003升級的藍圖 Exchange 2003升級的規劃
結論

39 案例分析 永生公司，在美國(45人)、大陸蘇州(300人)、台北(20人)、新竹(2500)、台中(1500)共五個廠，目前在每一個點都有自己的NT4 Domain和Exchange 5.5 Site，各網域之間均互相信任，公司決定要將所有的Exchange Server 5.5升級至Exchange Server 2003，台中廠要能夠使用OMA、Exchange ActiveSync、AUTD、及RPC over HTTP、ANTI-SPAM。

54 Active Directory帳戶清理精靈
MGB 2003 Active Directory帳戶清理精靈 適用時機 當NT4網域還未升級至Windows 2003前即與某一新AD以ADC建立關係，後來才升級為該AD的成員時 形成原因 在建立收件者連線協定(Recipient Connection Agreement)後已將NT4的帳號，以disable的形式存在於AD，故俟NT4網域升級為該AD的成員時，將產生帳戶的重複，故應合併為一個帳戶 合併方法 使用Exchange 2003所提供的Active Directory帳戶清理精靈 從開始所有程式Microsoft Exchange部署執行『Active Directory帳戶清理精靈』 © 2003 Microsoft Corporation.
