[网络协议]nginx 测评中低危险修复

1、检测到 RC4 密码套件、检测到 SHA-1 密码套件

在nginx的nginx.conf 文件中加入：

ssl_ciphers"ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";

ssl_prefer_server_ciphers on;

2、支持不推荐使用的 SSL 版本

将nginx.conf中的“ssl_protocols SSLv2 SSLv3 TLSv1;”改为“ssl_protocols TLSv1 TLSv1.1 TLSv1.2;”?

3、“Content-Security-Policy”头缺失或不安全

在nginx的nginx.conf 文件中加入：

add_header Content-Security-Policy "default-src 'self' localhost:8080 'unsafe-inline' 'unsafe-eval' blob: data: ;";

4、“X-Content-Type-Options”头缺失或不安全

在nginx的nginx.conf 文件中加入：add_header X-Content-Type-Options nosniff;

5、“X-XSS-Protection”头缺失或不安全

在nginx的nginx.conf 文件中加入：add_header X-XSS-Protection 1;和 add_header X-Xss-Protection: mod=block;

6、HTTP Strict-Transport-Security 头缺失或不安全

在nginx的nginx.conf 文件中加入：add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

7、发现可高速缓存的 SSL 页面

?在nginx的nginx.conf 文件中加入：add_header Cache-Control no-cache;

8、检测到隐藏目录（对禁止的资源发布“404 - Not Found”响应状态代码，或者将其完全除去）

在nginx的nginx.conf 文件中加入：error_page 403 =404 /404.html;

示例：

Server{

listen 443 ssl;

add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

add_header X-Content-Type-Options: nosniff;

add_header Content-Security-Policy "default-src 'self' 127.0.0.1:443 'unsafe-inline' 'unsafe-eval' blob: data: ;";

add_header X-XSS-Protection 1;

add_header X-Xss-Protection: mod=block;

ssl_ciphers"ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";

ssl_prefer_server_ciphers on;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_prefer_server_ciphers?? on;
