校園資訊防護範圍
規劃建置範圍:
資訊中心 (包括中心機房主機群、辦公室、電腦教室) 安全防護系
統,能有效控制單位內部網路之存取、即時偵測及阻絕電腦病毒與
駭客攻擊…等功能。
校園網路安全 (泛指非資訊中心以外所有電腦對電腦的資訊活動) ,
控制單位內部網路之存取、即時偵測及阻絕電腦病毒與駭客攻擊…
等功能,並且包含規劃建置各校無線網路之安全傳輸與身份認證機
制,包括強化無線網路使用之安全。
規劃建置上述各項設備之統一管理平台,同時具備分散式與集中式管
理機制,以達到有效、易於管理之目的,達成區域聯防網路安全機制。

FortiGate 網路實用規劃
部署4: 金流--信用卡刷卡機IPVPN資安解決方案
(PCI DSS Compliant) (FG60M)
部署5: 證券電子交易系統資訊安全規劃架構圖
部署6: 大型產險/壽險業UTM解決方案
(HA架構) 使用虛擬防護同
時保護Inside與DMZ
狀態:
在一台設備上切分兩個虛擬保護區
,同時保護Inside與DMZ網路
備援:
兩台UTM(Fortigate)做AA(ActiveActive)備援。除了不會有設備閒置
外,管理者只需設定Master設備,
Slave會自動同步所有設定;同時提
供外部服務的DMZ區也有備援機制
故障率:
以一台以故障率10%及網路設備以
HA方式介接故障率為相乘計算,
故障率為10% X 10% + 10%= 11%
User使用效能:
三台設備=2個節點,所有 User流量
在經過FG的load balance mode後能
得到更充份利用
效益:
兩台可作HA的FG價錢並不高於一
台NS+一台FG,效能卻遠遠超出

線路備援與機動性…
• One of the basic application is to use EVDO links
as primary lnternet connection.
• FG-60B and FW-60B support the use of EVDO
as a primary or secondary link.
 What is primary and what is secondary is just a
network interface configuration setting
 Policy-based routing can be used to split the traffic
load between Wan1 and Wan2 links. EVDO can take
over for a failed load balanced ethernet link.
• FG-60B and FW-60B protect the communication.
 All the standard protection features (Firewall, VPN,
IPS, Antivirus, AntiSpam, URL Filtering) work and
apply to an EVDO link.
