1、TLS问题

104743 - TLS 1.0 版协议检测
nginx使用配置选项: ssl_protocols  TLSv1.2 TLSv1.3
    
127907 - nginx 1.9.5 < 1.16.1 / 1.17.x < 1.17.3 Multiple Vulnerabilities
150154 - nginx 0.6.x < 1.20.1 1-Byte Memory Overwrite RCE
134220 - nginx < 1.17.7 Information Disclosure
升级nginx版本为1.21.1

2、ssl问题

57582 - SSL Self-Signed Certificate
51192 - SSL Certificate Cannot Be Trusted
104743 - TLS Version 1.0 Protocol Detection

443端口处理一下

3、请求方式限制

11213 - HTTP TRACE / TRACK Methods Allowed
42873 - SSL Medium Strength Cipher Suites Supported (SWEET32)
104743 - TLS Version 1.0 Protocol Detection

所有server的location中加入限制:仅允许get、post请求
     server {
         listen       80;
         server_name  paytest.org.cn;
         rewrite ^(.*)$ https://$host$1 permanent;
         location / {
             limit_except GET POST {
                 deny  all;
             }
      }

在pve中设置了443端口允许访问的白名单 

4、trace问题

11213 - HTTP TRACE / TRACK Methods Allowed

httpd的trace问题:
 vi /usr/local/apache/conf/httpd.conf
在尾部追加:TraceEnable off
重启httpd服务即可

5、TLS版本问题

104743 - TLS Version 1.0 Protocol Detection

# 原始配置
#ssl_protocols TLSv1 TLSv1.1 TLSv1.2 ;
# 修复配置
ssl_protocols TLSv1.2 TLSv1.3;

6、ssl算法问题

42873 - SSL Medium Strength Cipher Suites Supported (SWEET32)

 iptables -I INPUT -p tcp --dport 5432  -s 124.17.5.0/24  -j ACCEPT

 在nginx.conf中修改ssl的算法:
  ssl_ciphers HIGH:!aNULL:!MD5:!DES:!3DES;
