服务器系列：服务器禁用TLS1.0和TLS1.1协议使网站更安全

SSL/TLS 的版本

Nginx

1. 通常Nginx的conf/nginx.conf配置如下

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

1. 删除TLS1.0 TLSv1.1、增加TLS1.3

ssl_protocols TLSv1.2 TLSv1.3;

1. 重启Nginx使配置生效

nginx -s reload

Apache

1. 通常Apache的配置如下

SSLProtocol -ALL +TLSv1 +TLSv1.1 +TLSv1.2

1-1. 基于RedHat的发行版（CentOS，Fedora）配置文件/etc/httpd/conf/httpd.conf
1-2. 基于Debian的发行版（Ubuntu）配置文件/etc/apache2/sites-enabled/目录下

1. 删除+TLSv1 +TLSv1.1、增加TLSv1.3

SSLProtocol -ALL +TLSv1.2 +TLSv1.3  

1. 重启Apache使配置生效

# 基于RedHat的发行版（CentOS，Fedora）
systemctl restart httpd
 
# 基于Debian的发行版（Ubuntu）
service apache2 restart   

IIS服务器

1. IIS服务器需使用官方工具（IISCrypto.exe ）进行修改

IISCrypto.exe

Tomcat

1. 通常Tomcat的conf/server.xml配置如下

SSLProtocol="TLSv1+TLSv1.1+TLSv1.2"

1. 删除+TLSv1 +TLSv1.1、增加TLS1.3

SSLProtocol="TLSv1.2+TLSv1.3"

1. 重启Tomcat使配置生效

# 关闭tomcat
bin/shutdown.sh 
 
# 启动tomcat
bin/startup.sh 

• 注：以上服务器增TLS1.3需要依赖openSSL的版本以及IIS和Java的版本的支持

检测

一、测试TLS1.0协议

openssl s_client -connect www.example.com:443 -tls1  < /dev/null

CONNECTED(00000003)
write:errno=104
---
no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 0 bytes and written 0 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
No ALPN negotiated
SSL-Session:
    Protocol  : TLSv1
    Cipher    : 0000
    Session-ID: 
    Session-ID-ctx: 
    Master-Key: 
    Key-Arg   : None
    Krb5 Principal: None
    PSK identity: None
    PSK identity hint: None
    Start Time: 1633685489
    Timeout   : 7200 (sec)
    Verify return code: 0 (ok)
---

• 注： 表示使用TLS1.0协议连接不通，说明我们已经禁用了TLS1.0

二、测试TLS1.2协议

openssl s_client -connect www.example.com:443 -tls1_2  < /dev/null

CONNECTED(00000003)
