"Oracle Advanced Security提供加密和編輯兩個重要的預防性控件來保護源頭的敏感資料。
透明資料加密（TDE）透過在資料庫層中執行靜態資料加密阻止潛在攻擊者繞過資料庫，直接從存儲中讀取敏感信息。
資料編輯透過降低應用程序中未經授權的資料暴露的風險，在敏感資料離開資料庫之前對其進行編輯以補充TDE。"

加密和編輯兩個重要的控件構成Oracle深度防禦、多層資料庫安全的基礎，提供業界先進的資料庫加密解決方案，與 Oracle 資料庫的所有通訊都可以使用得以進行加密。網路中資料可透過加密保護其機密性，防止資料嗅探、丟失及攻擊。

"Memory需求，Each x86 64-bit server must have the following minimum memory:
Audit Vault Server: 8 GBFoot 1
Database Firewall: 8 GB

Disk需求，Each x86 64-bit server must have a single hard drive with a minimum of the following disk space:
Audit Vault Server: 220 GB (Recommended is 300 GB)
Database Firewall: 220 GB

Network需求，Oracle recommends the following number of network interface cards (NICs) for each x86 64-bit server on which you install the following components:
1 NIC for the Audit Vault Server
At least 1 NIC for a Database Firewall operating as a proxy
At least 2 NICs for a Database Firewall in DAM Mode (monitoring only)
At least 3 NICs for a Database Firewall in DPE Mode (monitoring and blocking. If you install the Database Firewall with fewer than 3 NICs, then you must add more NICs to make the Database Firewall DPE mode possible."
