網路服務資料安全有以下特性：

完整性(Integrity)

機密性(confidentiality)

確認性(authentication)

可稽核性(accountability) :
帳戶辨識記錄能力：系統辨識使用者及記與安全性相關活動能力
借由稽核紀錄追蹤非法使用者

不可否認性(non-repudiation)

Really wanna to have a house for the heart.

Two similar guys show up.

I couldn't commit anything for one of them.

I know they are good men.

I think to fall in love really needs some "guts" for me.

I am not sure if I could love again.

Sometimes I just wanna ask : is the possbility so rare to meet the right guy??

Once in the TV show that singer coco said that :

....when you meet the right one,you will know it.

He will bring out the good side of you and just trust yourself.Trust your feeling.

Love is simple.

True love is simple.

Wish my heart will lead me to find the adopest one.

Yes, I think I have to try,to take chances for it.

Thanks for Celine::

I really like what this song told.

What do you say?

I have to admit that I am still waiting.

I need guts, you need ,too!!

Inprovement:

2-weeks study in NCTU lib makes me find my study feeling, though the facial surgery makes me pain and stop me to go to the lib.
I could concentrate in my dooroom , I think the weather is getting cold do help me a lot.

schedule:

1. KM ~ Ch7 (stiil need to get more familiar for KM)
2. Java~ Array(not yet)

reflections:

things getting better and better as long as I don't always think about dark side.
everything has it's own steps and every step just like SDLC, we can't avoid any stage of it.
must be strong and then God will help you.
Beleive and insist. It's easy to say,but not easy to act.
I feel uncertain,but trying to keep my words.

SISP的關鍵成功因素

2009-09-08T09:47:00.001+08:00

1.策略
2.系統效能

02【資訊系統開發模式】

2009-09-07T12:01:00.001+08:00

瀑布模式(waterfall = SDLC):

三階段瀑布模式:分析(可行性，需求，系統分析)→設計(概念性，細部設計)→實施(程式編輯，單元測試，整合測試，安裝與系統測試，教育訓練及操作維護)
強調系統開發過程須有完整規劃，分析設計，測試及文件管理與控制。
[ 缺點 ] ::

2.螺旋模式 spiral model

3.雛形模式 prototype model

01概論

2009-09-04T12:01:00.000+08:00

資安目的->維護 C.I.A :: 保密性，完整性，可用性
木馬:偽裝成別的程式進入系統或網路
邏輯炸彈:被放置在受害系統中的軟體程式，被設定在某條件下啟動一些破壞性功能
社交工程:
DES(對稱式加密):

優點: 運算速度快，加密法強度高，軟硬體建置不難
缺點: 加解密使用同把key，key 管理的複雜性，

AES::使用128bit 狀態表
雜湊:將任意長度訊息字串轉化成固定長度之輸出字串(hash value)
數位簽章:非對稱加密+hash→ 保證文件完整性與傳送方向不可否認性。
PKI:

憑證管理中心(CA)::負責發行，撤銷，配送數位憑證
註冊管理中心::
RSA::
數位憑證(digital certificate)::

5.PGP: 電子郵件加密系統的一種自由軟體
6.SSH: 一種安全通道協定，VPN之外的一種選擇，

電子郵件客戶端- SSH通道 - SSH伺服器 - 郵件伺服器。

   7.HTTPS:在客戶端與伺服器間建立SSL安全管道。
   8.IPsec: VPN的一種加密標準。大部分網路平台都支援此協定。IPv6必備功能。
   9.防火牆

封包過濾型::依據封包來源/目的IP位址，資訊流常指來源與目的間的網路通訊協定，可能包含傳輸層訊息，可能包含來源與目的路由器介面訊息
狀態檢查型::
應用代理閘道型::

ch8 無線通訊網路

2009-09-03T14:15:00.000+08:00

Def. :利用無線電波連接包括電腦在內的各種設備。
Protocol:: IEEE802.11 ，0.0192Mbps~20Mbps
