When MySQL is replicating across the internet, others can steal information about MySQL's replication, which is plaintext, so there is no security, where the replicated information is encrypted via SSL. When the client does not have a fixed IP to access the server, MySQL to allow access to arbitrary addresses, server and client through certificate validation can prevent violent cracking. Before we begin, let's review the installation process for

The general FTP server is in plaintext transmission of data, security is very poor, information is easily stolen, even if it provides SSL encryption, by default may not be enabled, such as the Common Serv-u FTP server (hereinafter referred to as Serv-u). In order to ensure data security in a particular environment, it is sometimes necessary to enable SSL functionality. The following is an example of a serv-

In order to ensure data security in a particular environment, it is sometimes necessary to enable SSL functionality. The following is an example of a serv-u server that describes how to enable SSL encryption. Creating an SSL Certificate To use the Serv-u SSL feature, you will of course need the

Ssl vpn Definition The development of ssl vpn is a supplement to the existing SSL applications. It increases the access control and security level and capability of the company. Ssl vpn also helps enterprises that use remote access to the application system to reduce their security. In terms of attributes, dialing ensu

Introduction 　　 The current version of SSLv3 is version 3.1, also known as TLS. It provides a mechanism for secure data transmission over the network. It is said to meet all security needs, such as your bank account management. 　　 But here I will tell you that this is actually impossible. 　　 In this article, I will first introduce SSL, which is very important. However, we will not introduce deep issues such as how

High-risk vulnerabilities exposed by SSL 3.0 On April 9, October 15, 2014, Google researchers announced a very serious vulnerability in the SSL 3.0 protocol, which can be used by hackers to intercept encrypted data transmitted between browsers and servers, such as online banking accounts, email accounts, and personal privacy. The SSL 3.0 vulnerability allows atta

1. About OpenSSLThe OpenSSL project is a collaborative development of a robust, commercial-grade, full-featured, open-source toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a fully-powerful universal cryptographic library.2. Using SSL for Secure IOUsing SSL for Secure IO is not very different fro

Detailed tutorial on MySQL master-slave Replication Based on the SSL protocol, When mysql is replicated across the Internet, others can steal the mysql replication information, which is in plain text and therefore insecure. Here, the copied information is encrypted through ssl. When a customer wants to access the server without a fixed ip address, mysql must allow access from any address. The server and cli

SSL VPN principle If you separate the two concepts of SSL and VPN, you should know what they mean, but as a new technology, how they are combined may not be well understood. From the academic and commercial point of view, because they represent a different meaning, so often be misinterpreted. SSL (Secure Sockets Layer) protocol is a common protocol that guarant

If our site projects are not important business sites, such as personal sites, blogs or simple projects need to use the SSL security certificate, in fact, the Internet currently provides a free SSL certificate enough for us to choose and use.
