We have introduced a new policy for you to enforce on your non-privileged users. It requires their current password at the time they set a new password. It is optional and off by default. You can control it globally (for all non-privileged users) or on a per-user basis.…

If you’re here, that probably means you’re about to acquire some sensitive data to take care of. Or that you’ve already acquired it and are protecting it, and you want to see how MySQL Enterprise Data Masking and De-Identification features can help you do it in an easier, better and more efficient manner.…

The new release 8.0.13 for MySQL is available since last week.
Concerning security, this comes with a new feature already announced: the Password Verification Policy.
Let’s have a look…

This aim of this feature is to secure the attempts to change a password by specifying the old one to be replaced.
It is turned off by default:

mysql> show variables like 'password_require_current';
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| password_require_current | OFF   |
+--------------------------+-------+

and we can activate it by several ways (as for some other password features):
1. Globally, at the server level:

mysql> set persist password_require_current='ON';
mysql> show variables like 'password_require_current';
+--------------------------+-------+
| Variable_name            | Value | …

To use Percona XtraBackup with keyring_vault plugin enabled you need to take some special measures to secure a working backup. This post addresses how to backup Percona Server for MySQL with keyring_vault plugin enabled. We also run through the steps needed to restore the backup from the master to a slave.

This is the second of a two-part series on setting up Hashicorp Vault with Percona Server for MySQL with the keyring_vault plugin. First part is Using the keyring_vault plugin with Percona Server for MySQL 5.7.

Backing up from the master

First you need to install the latest Percona XtraBackup 2.4 package, in this tutorial I used this version:

[root@mysql1 ~]# xtrabackup --version
xtrabackup: recognized server arguments: --datadir=/var/lib/mysql --log_bin=mysqld-bin …

In this blog post, we review some of the important aspects of configuring and managing SSL in MySQL hosting. These would include the default configuration, disabling SSL, and enabling and enforcing SSL on a MySQL server. Our observations are based on the community version of MySQL 5.7.21.

Default SSL Configuration in MySQL

By default, MySQL server always installs and enables SSL configuration. However, it is not enforced that clients connect using SSL. Clients can choose to connect with or without SSL as the server allows both types of connections. Let’s see how to verify this default behavior of MySQL server.

When SSL is installed and enabled on MySQL server by default, we will typically see the following:

1. Presence of *.pem files in the MySQL data directory. These are the various client and server certificates and keys that are in …

This is the first of a two-part series on using the keyring_vault plugin with Percona Server for MySQL 5.7. The second part, Backing up Percona Server for MySQL with keyring_vault plugin enabled, walks through how to use Percona Xtrabackup to backup from this instance and restore to another server and set it up as a slave with keyring_vault plugin.

What is the keyring_vault plugin?

The keyring_vault is a plugin that allows the database to interface with a Hashicorp Vault server to store and secure encryption keys. The Vault server then acts as a centralized encryption key management solution which is critical for security and for compliance with various security standards.

Configuring Vault

Create SSL certificates to be used by Vault. You can use …

In my last post I compared data at-rest encryption features available for MySQL and MariaDB. As noted at the time, some of the features available for Percona Server for MySQL were in development, and the latest version (5.7.23) sees two of them released as ALPHA quality.

Encrypting the InnoDB system tablespace

The first of the new features is InnoDB system tablespace encryption via innodb_sys_tablespace_encrypt, which …

It’s 2018. Maybe now is the time to start migrating your network to IPv6, and your database infrastructure is a great place to start. Unfortunately, many legacy applications don’t offer the option to connect to MySQL directly over IPv6 (sometimes even if passing a hostname). We can work around this by using ProxySQL’s IPv6 support which was added in version 1.3. This will allow us to proxy incoming IPv4 connections to IPv6-only database servers.

Note that by default ProxySQL only listens on IPv4. We don’t recommended changing that until this bug is resolved. The bug causes ProxySQL to segfault frequently if listening on IPv6.

In this example I’ll use centos7-pxc57-1 as my database server. It’s running …

Protecting the data stored in your database may have been at the top of your priorities recently, especially with the changes that were introduced earlier this year with GDPR.

There are a number of ways to protect this data, which until not so long ago would have meant either using an encrypted filesystem (e.g. LUKS), or encrypting the data before it is stored in the database (e.g. AES_ENCRYPT or other abstraction within the application). A few years ago, the options started to change, as Alexander Rubin discussed in …
