将以下内容添加到您的 composer.json 的 require 部分中。

用法

require __DIR__ . '/vendor/autoload.php';

$config = [
    'logDirectory' => __DIR__ . "/firewall_logs",
    'logFilesCount' => 10,
    'allowAttackCount' => 5,
    'active' => true,
    'protection' => [
        'allowedRequestMethod' => [
            'active' => true
        ],
        'allowedGlobals' => [
            'active' => false
        ],
        'urlLength' => [
            'active' => true,
            'rules' => 200,
        ],
        'getProtection' => [
            'active' => true,
            'rules' => ['select', 'from'],
        ],
        'urlProtection' => [
            'active' => true,
            'rulesFile' => 'path/to/rulesFile.json'
        ],
        'whitelistIp' => [
            'active' => true,
            'rules' => ['127.0.0.1', '::1']
        ],
        'blacklistIp' => [
            'active' => true,
            'rules' => ['23.254.0.1', '22.23.22.8']
        ]
    ]
];

$firewall = new \karster\security\Firewall($config);
$firewall->run();

或者

require __DIR__ . '/vendor/autoload.php';

$protections = [
    'allowedRequestMethod' => [
        'active' => true
    ],
    'allowedGlobals' => [
        'active' => false
    ],
    'urlLength' => [
        'active' => true,
        'rules' => 200,
    ],
    'getProtection' => [
        'active' => true,
        'rules' => ['select', 'from'],
    ],
    'urlProtection' => [
        'active' => true,
        'rulesFile' => 'path/to/rulesFile.json'
    ],
    'whitelistIp' => [
        'active' => true,
        'rules' => ['127.0.0.1', '::1']
    ],
    'blacklistIp' => [
        'active' => true,
        'rules' => ['23.254.0.1', '22.23.22.8']
    ]
];

$firewall = new \karster\security\Firewall();
$firewall->setAllowAttackCount(5)
         ->setActive(true)
         ->setLogDirectory(__DIR__ . "/firewall_logs")
         ->setLogFilesCount(10)
         ->setProtection($protections)
         ->run();
  • logDirectory - string - 防火墙可写入的目录路径
  • logFilesCount - integer - 删除比特定数量更旧的日志。设置 0 以禁用
  • allowAttackCount - integer - 在黑名单之前来自同一IP地址的攻击计数(需要 logDirectory)。设置 0 以禁用
  • active - boolean - 默认 true
  • protection - array - 关联数组,其中键是保护名称,值是保护配置

保护

我们可以选择不同的保护类型

  • allowedRequestMethod
  • allowedGlobals
  • blacklistIp
  • cookieProtection
  • getProtection
  • postProtection
  • sessionProtection
  • urlLength
  • urlProtection

每个保护都包含具有参数的配置数组

  • active boolen - 默认 true
  • rules array|integer - 除了 urlLength 保护(它接受整数)之外,每个保护都接受数组
  • rulesFile string - 包含规则的json文件路径
'cookieProtection' => [
    'active' => true,
    'rules' => [
        'select', 'from', 'where'
    ],
    // or
    'rulesFile' => 'path/to/rulesFile.json'
]

如果没有设置 rulesrulesFile,则使用默认规则。
