    NVT: SSL/TLS: Deprecated TLSv1.0 and TLSv1.1 Protocol Detection
    Summary
    It was possible to detect the usage of the deprecated TLSv1.0 and/or TLSv1.1 protocol on this system.
    Vulnerability Detection Result
    In addition to TLSv1.2+ the service is also providing the deprecated TLSv1.0 and
    ,→ TLSv1.1 protocols and supports one or more ciphers. Those supported ciphers c
    ,→an be found in the 'SSL/TLS: Report Supported Cipher Suites' (OID: 1.3.6.1.4.1
    ,→.25623.1.0.802067) VT.
    Impact
    An attacker might be able to use the known cryptographic aws to eavesdrop the connection
    between clients and the service to get access to sensitive data transferred within the secured
    connection.
    Furthermore newly uncovered vulnerabilities in this protocols won't receive security updates
    anymore.
    Solution:
    Solution type: Mitigation
    It is recommended to disable the deprecated TLSv1.0 and/or TLSv1.1 protocols in favor of the
    TLSv1.2+ protocols. Please see the references for more information.
    Aected Software/OS
    All services providing an encrypted communication using the TLSv1.0 and/or TLSv1.1 protocols.
    Vulnerability Insight
    The TLSv1.0 and TLSv1.1 protocols contain known cryptographic aws like:

    Vulnerability Detection Method
    Check the used TLS protocols of the services provided by this system.

解决办法：禁用已弃用的TLSv1.0和/或TLSv1.1协议,以支持TLSv1.2+协议。

TLS发展历史：

##### 1、Nginx配置 #####

如果`conf/nginx.conf`配置了ssl证书，且`default_server`的`server`域里面版本如下

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

则删除`TLS1.0 TLSv1.1`、增加TLS1.3

ssl_protocols TLSv1.2 TLSv1.3;

修改完后，执行`./sbin/nginx -s reload`重载生效。

##### 2、Apache配置 #####

修改`/usr/local/apache/conf/extra/httpd-ssl.conf`文件

vi /usr/local/apache/conf/extra/httpd-ssl.conf
