安全 HTTP 响应标头

您可以使用安全 HTTP 响应标头来提高 Web 应用程序的安全性。 本节专门介绍对安全 HTTP 响应标头的基于 servlet 的支持。spring-doc.cn

默认安全标头

Spring Security 提供了一组默认的安全 HTTP 响应 Headers 来提供安全的默认值。 虽然这些标头中的每一个都被视为最佳实践,但应该注意的是,并非所有客户端都使用标头,因此鼓励进行额外的测试。spring-doc.cn

您可以自定义特定的标头。 例如,假设你想要默认值,但希望为 X-Frame-Options 指定。SAMEORIGINspring-doc.cn

您可以使用以下配置执行此操作:spring-doc.cn

自定义默认安全标头
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.frameOptions(frameOptions -> frameOptions
					.sameOrigin()
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<frame-options policy="SAMEORIGIN" />
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {
    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                frameOptions {
                    sameOrigin = true
                }
            }
        }
        return http.build()
    }
}

如果您不希望添加默认值并希望明确控制应使用的内容,则可以禁用默认值。 下一个代码清单显示了如何执行此操作。spring-doc.cn

如果使用 Spring Security 的配置,则以下内容仅添加缓存控制spring-doc.cn

自定义缓存控制标头
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				// do not use any default headers unless explicitly listed
				.defaultsDisabled()
				.cacheControl(withDefaults())
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers defaults-disabled="true">
		<cache-control/>
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {
    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                // do not use any default headers unless explicitly listed
                defaultsDisabled = true
                cacheControl {
                }
            }
        }
        return http.build()
    }
}

如有必要,您可以使用以下配置禁用所有 HTTP 安全响应标头:spring-doc.cn

禁用所有 HTTP 安全标头
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers.disable());
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers disabled="true" />
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {
    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                disable()
            }
        }
        return http.build()
    }
}

缓存控制

默认情况下,Spring Security 包括 Cache Control 标头。spring-doc.cn

但是,如果你真的想缓存特定的响应,你的应用程序可以选择性地调用HttpServletResponse.setHeader(String,String)来覆盖 Spring Security 设置的 Header。 您可以使用它来确保正确缓存内容(如 CSS、JavaScript 和图像)。spring-doc.cn

当您使用 Spring Web MVC 时,这通常在您的配置中完成。 您可以在 Spring 参考文档的 Static Resources 部分找到有关如何执行此操作的详细信息spring-doc.cn

如有必要,您还可以禁用 Spring Security 的缓存控制 HTTP 响应标头。spring-doc.cn

已禁用缓存控制
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.cacheControl(cache -> cache.disable())
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<cache-control disabled="true"/>
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
       http {
            headers {
                cacheControl {
                    disable()
                }
            }
        }
        return http.build()
    }
}

内容类型选项

Spring Security 默认包括 Content-Type 标头。 但是,您可以禁用它:spring-doc.cn

内容类型选项已禁用
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.contentTypeOptions(contentTypeOptions -> contentTypeOptions.disable())
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<content-type-options disabled="true"/>
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
       http {
            headers {
                contentTypeOptions {
                    disable()
                }
            }
        }
        return http.build()
    }
}

HTTP 严格传输安全 (HSTS)

默认情况下,Spring Security 提供 Strict Transport Security 标头。 但是,您可以显式自定义结果。 以下示例显式提供 HSTS:spring-doc.cn

严格的运输安全
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.httpStrictTransportSecurity(hsts -> hsts
					.includeSubDomains(true)
					.preload(true)
					.maxAgeInSeconds(31536000)
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<hsts
			include-subdomains="true"
			max-age-seconds="31536000"
			preload="true" />
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            headers {
                httpStrictTransportSecurity {
                    includeSubDomains = true
                    preload = true
                    maxAgeInSeconds = 31536000
                }
            }
        }
        return http.build()
    }
}

HTTP 公钥固定 (HPKP)

Spring Security 为 HTTP 公钥固定提供了 servlet 支持,但不再推荐使用。spring-doc.cn

您可以使用以下配置启用 HPKP 标头:spring-doc.cn

HTTP 公钥固定
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.httpPublicKeyPinning(hpkp -> hpkp
					.includeSubDomains(true)
					.reportUri("https://example.net/pkp-report")
					.addSha256Pins("d6qzRu9zOECb90Uez27xWltNsj0e1Md7GkYYkVoZWmM=", "E9CZ9INDbd+2eRQozYqqbQ2yXLVKB9+xcprMF+44U1g=")
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<hpkp
			include-subdomains="true"
			report-uri="https://example.net/pkp-report">
			<pins>
				<pin algorithm="sha256">d6qzRu9zOECb90Uez27xWltNsj0e1Md7GkYYkVoZWmM=</pin>
				<pin algorithm="sha256">E9CZ9INDbd+2eRQozYqqbQ2yXLVKB9+xcprMF+44U1g=</pin>
			</pins>
		</hpkp>
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            headers {
                httpPublicKeyPinning {
                    includeSubDomains = true
                    reportUri = "https://example.net/pkp-report"
                    pins = mapOf("d6qzRu9zOECb90Uez27xWltNsj0e1Md7GkYYkVoZWmM=" to "sha256",
                            "E9CZ9INDbd+2eRQozYqqbQ2yXLVKB9+xcprMF+44U1g=" to "sha256")
                }
            }
        }
        return http.build()
    }
}

X 框架选项

默认情况下,Spring Security 指示浏览器使用 X-Frame-Options 来阻止反射的 XSS 攻击。spring-doc.cn

例如,以下配置指定 Spring Security 不应再指示浏览器阻止内容:spring-doc.cn

X 框架选项:SAMEORIGIN
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.frameOptions(frameOptions -> frameOptions
					.sameOrigin()
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<frame-options
		policy="SAMEORIGIN" />
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            headers {
                frameOptions {
                    sameOrigin = true
                }
            }
        }
        return http.build()
    }
}

X-XSS 保护

默认情况下,Spring Security 指示浏览器通过使用<<headers-xss-protection,X-XSS-Protection头>来禁用 XSS 审计器。 但是,您可以更改此默认值。 例如,以下配置指定 Spring Security 指示兼容的浏览器启用过滤, 并阻止内容:spring-doc.cn

X-XSS-Protection 定制
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.xssProtection(xss -> xss
					.headerValue(XXssProtectionHeaderWriter.HeaderValue.ENABLED_MODE_BLOCK)
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<xss-protection headerValue="1; mode=block"/>
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        // ...
        http {
            headers {
                xssProtection {
                    headerValue = XXssProtectionHeaderWriter.HeaderValue.ENABLED_MODE_BLOCK
                }
            }
        }
        return http.build()
    }
}

内容安全策略 (CSP)

Spring Security 默认情况下不添加内容安全策略,因为如果不了解应用程序的上下文,就不可能知道合理的默认值。 Web 应用程序作者必须声明安全策略(或多个策略)以强制实施或监控受保护的资源。spring-doc.cn

请考虑以下安全策略:spring-doc.cn

内容安全策略示例
Content-Security-Policy: script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/

根据上述安全策略,您可以启用 CSP 标头:spring-doc.cn

内容安全策略
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.contentSecurityPolicy(csp -> csp
					.policyDirectives("script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/")
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<content-security-policy
			policy-directives="script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/" />
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                contentSecurityPolicy {
                    policyDirectives = "script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/"
                }
            }
        }
        return http.build()
    }
}

要启用 CSP 标头,请提供以下配置:report-onlyspring-doc.cn

仅内容安全策略报告
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.contentSecurityPolicy(csp -> csp
					.policyDirectives("script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/")
					.reportOnly()
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<content-security-policy
			policy-directives="script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/"
			report-only="true" />
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                contentSecurityPolicy {
                    policyDirectives = "script-src 'self' https://trustedscripts.example.com; object-src https://trustedplugins.example.com; report-uri /csp-report-endpoint/"
                    reportOnly = true
                }
            }
        }
        return http.build()
    }
}

					.policy(ReferrerPolicy.SAME_ORIGIN)
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<referrer-policy policy="same-origin" />
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                referrerPolicy {
                    policy = ReferrerPolicy.SAME_ORIGIN
                }
            }
        }
        return http.build()
    }
}

	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                featurePolicy("geolocation 'self'")
            }
        }
        return http.build()
    }
}

权限策略

默认情况下,Spring Security 不添加 Permissions Policy 标头。 请考虑以下标头:Permissions-Policyspring-doc.cn

Permissions-Policy 示例
Permissions-Policy: geolocation=(self)

您可以使用以下配置启用上述权限策略标头:spring-doc.cn

权限策略
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http

			.headers(headers -> headers
				.permissionsPolicy(permissions -> permissions
					.policy("geolocation=(self)")
				)
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<permissions-policy policy="geolocation=(self)" />
	</headers>
</http>
@Configuration
@EnableWebSecurity

        http {
            // ...
            headers {
                permissionPolicy {
                    policy = "geolocation=(self)"
                }
            }
        }
        return http.build()
    }
}

清除站点数据

            }
        }
        return http.build()
    }
}

自定义标头

Spring Security 具有一些机制,可以方便地将更常见的安全 Headers 添加到您的应用程序中。 但是,它还提供了 hook 来启用添加自定义标头。spring-doc.cn

静态标头

有时,您可能希望将不支持的自定义安全标头注入到您的应用程序中。 请考虑以下自定义安全标头:spring-doc.cn

X-Custom-Security-Header: header-value

给定前面的标头,您可以使用以下配置将标头添加到响应中:spring-doc.cn

静态标头写入器
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.addHeaderWriter(new StaticHeadersWriter("X-Custom-Security-Header","header-value"))
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<header name="X-Custom-Security-Header" value="header-value"/>
	</headers>
</http>
@Configuration
@EnableWebSecurity
class SecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            // ...
            headers {
                addHeaderWriter(StaticHeadersWriter("X-Custom-Security-Header","header-value"))
            }
        }
        return http.build()
    }
}

标头写入器

当命名空间或 Java 配置不支持所需的标头时,您可以创建自定义实例,甚至可以提供 .HeadersWriterHeadersWriterspring-doc.cn

下一个示例使用 的自定义实例。 如果要显式配置 X-Frame-Options,可以使用以下配置来实现:XFrameOptionsHeaderWriterspring-doc.cn

标头写入器
@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.headers(headers -> headers
				.addHeaderWriter(new XFrameOptionsHeaderWriter(XFrameOptionsMode.SAMEORIGIN))
			);
		return http.build();
	}
}
<http>
	<!-- ... -->

	<headers>
		<header ref="frameOptionsWriter"/>
	</headers>
</http>
<!-- Requires the c-namespace.

            headers {
                addHeaderWriter(XFrameOptionsHeaderWriter(XFrameOptionsMode.SAMEORIGIN))
            }
        }
        return http.build()
    }
}

委托RequestMatcherHeaderWriter

有时,您可能希望仅为某些请求编写标头。 例如,也许您只想保护登录页不被框定。 您可以使用 来执行此操作。DelegatingRequestMatcherHeaderWriterspring-doc.cn

以下配置示例使用:DelegatingRequestMatcherHeaderWriterspring-doc.cn

DelegatingRequestMatcherHeaderWriter Java 配置
@Configuration
@EnableWebSecurity
