Oracle客户端安全概述** Oracle客户端是与Oracle数据库交互的软件组件。确保其安全至关重要,因为它可以作为攻击者访问数据库的入口点。Oracle客户端安全涉及保护客户端免受未经授权的访问、数据泄露和恶意软件感染。本章概述了Oracle客户端安全的重要性、常见的威胁以及保护客户端的最佳实践。 # 2. Oracle客户端配置最佳实践** **2.1 网络配置安全** **2.1.1 加密连接** **目的:**保护客户端与数据库服务器之间的通信免受窃听和篡改。 **配置步骤:** 1. 在客户端配置 TNS 监听器,启用 SSL/TLS 加密: ``` LISTENER = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) (SSL_SERVER_DN = "CN=example.com, OU=IT, O=Example Corp, L=New York, ST=New York, C=US") ) ``` 2. 在客户端应用程序中指定 SSL/TLS 连接: ```java Properties props = new Properties(); props.setProperty("oracle.net.ssl_server_dn", "CN=example.com, OU=IT, O=Example Corp, L=New York, ST=New York, C=US"); ``` **逻辑分析:** * `LISTENER` 块配置 TNS 监听器,指定 TCP 和 IPC 地址。 * `SSL_SERVER_DN` 参数指定服务器的 SSL 证书颁发者名称,客户端将验证此名称以确保连接安全。 * 客户端应用程序使用 `oracle.net.ssl_server_dn` 属性指定要连接的服务器的 SSL 证书颁发者名称。 **2.1.2 限制访问** **目的:**限制对数据库服务器的访问,仅允许授权用户连接。 **配置步骤:** 1. 在 TNS 监听器中配置访问控制列表 (ACL): ``` LISTENER = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) (ACL = (CONNECT = (USER = username))) ) ``` 2. 在客户端应用程序中指定访问控制列表: ```java Properties props = new Properties(); props.setProperty("oracle.net.authentication_services", "(ACL)"); ``` **逻辑分析:** * `ACL` 块配置访问控制列表,指定允许连接的用户名。 * 客户端应用程序使用 `oracle.net.authentication_services` 属性指定要使用的身份验证服务,在这种情况下为 ACL。 **2.2 身份验证和授权** **2.2.1 强密码策略** **目的:**实施强密码策略以防止未经授权的访问。 **配置步骤:** 1. 在数据库服务器上配置密码策略: ```sql ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED; ALTER PROFILE DEFAULT LIMIT PASSWORD_REUSE_MAX 0; ALTER PROFILE DEFAULT LIMIT PASSWORD_REUSE_TIME 0; ALTER PROFILE DEFAULT LIMIT PASS ```
