    Security

    HTTPS - HTTP over SSL

    工作原理:

    1. 使用非對稱式加密演算法來對通訊雙方做身分認證
    2. 並交換對稱金鑰為Session Key
    3. 使用Session Key來加密C/S間的通訊內容

    缺點:

    1. 通訊內容加量，因此傳輸時間變長
    2. 加解密需消耗額外機器資源 (可由SSL acceleration加速之)

    Apache httpd建置

    win7

    1. 目錄預設檔案

      1
      2
      3
      <IfModule dir_module>
          DirectoryIndex index.php
      </IfModule>

    2. apache安裝目錄
      Define SRVROOT "D:\dvp\dev-tool\httpd-2.4.16-x64-vc11\Apache24"

    3. 網頁根目錄
      DocumentRoot "D:\dvp\workspace\classroom2001\project"
      <Directory "D:\dvp\workspace\classroom2001\project">

    4. 介紹apache認識php

      1
      2
      3
      LoadModule php5_module "D:\dvp\dev-tool\php-5.6.11-Win32-VC11-x64\php5apache2_4.dll"
      AddType application/x-httpd-php .php
      PHPIniDir "D:\dvp\dev-tool\php-5.6.11-Win32-VC11-x64"

    5. 網頁重導設定
      LoadModule rewrite_module modules/mod_rewrite.so

      1
      2
      3
      4
      5
      6
      7
      <IfModule mod_rewrite.c>
      RewriteEngine On
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteCond %{REQUEST_FILENAME} !-d
      #RewriteRule api/v1/(.*)$ phpinfo.php?request=$1 [QSA,NC,L]
      RewriteRule api/(.*)$ /api/controller.php?request=$1 [QSA,NC,L]
      </IfModule>

    6. 環境變數$PATH加入D:\dvp\dev-tool\httpd-2.4.16-x64-vc11\Apache24\bin

    7. 防止diretory listing (Production)

      1
      2
      #Options Indexes FollowSymLinks
      Options FollowSymLinks

    8. Cross-Origin Resource Sharing (Optional)，於DocumentRoot的Diretory裡設定
      LoadModule headers_module modules/mod_headers.so

      1
      2
      3
      <IfModule mod_headers.c>
        Header set Access-Control-Allow-Origin "*"
      </IfModule>

    9. 註冊到service後，可使用Apache Monitor管理
      httpd.exe -k install [-n MyServiceName]

    ※使用service開啟httpd無法載入curl，原因是apache認不到curl在PHP目錄裡的依賴包libssh2.dll
    PHP Fatal error: Call to undefined function curl_init()
    解法: 將libssh2.dll複製一份到apache/bin再重啟

    參考WebProgramSecurity.pdf，有server-side及client-side，極重要

    • SQL Injection
    • Server Configuration
    • XSS / CSRF
      – captcha: 可參考0702 Lab_CAPTCHA
      – anti CSRF token
    • ClickJacking
      – frame bustering
      – header(“X-Frame-Options: Deny”);

    ##laravel
    Application key [TlDlIaffLhhfrgA5doqNw6iecg9KjNoU] set successfully.

    win7

    1. 顯示錯誤
      display_errors = On

    2. 設置extension目錄
      extension_dir = "D:\dvp\dev-tool\php-5.6.11-Win32-VC11-x64\ext"

    3. enable extenstions
      extension=php_bz2.dll
      extension=php_curl.dll
      extension=php_gd2.dll
      extension=php_mbstring.dll
      extension=php_exif.dll
      extension=php_mysql.dll
      extension=php_mysqli.dll
      extension=php_pdo_mysql.dll

    4. 時區
      date.timezone = Asia/Taipei

    5. 環境變數$PATH加入D:\dvp\dev-tool\php-5.6.11-Win32-VC11-x64

    6. 設置最大post size - Production
      post_max_size = 1M

    OSX (extra)

    開啟xdebug

    zend_extension = "xdebug.so"

    Composer

    curl -sS https://getcomposer.org/installer | php
