MySQL : InnoDB Transparent Tablespace Encryption

From MySQL 5.7.11, encryption is supported for InnoDB (file-per-table) tablespaces. This is called Transparent Tablespace Encryption or sometimes referred as Encryption at Rest. This blog post aims to give the internal details of InnoDB Tablespace Encryption.

Keyring Plugin : Why What How ?

Backing up Percona Server for MySQL with keyring_vault plugin enabled

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 …

Using the keyring_vault Plugin with Percona Server for MySQL 5.7

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 enabledwalks 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 …

Encryption of the InnoDB System Tablespace and Parallel Doublewrite Buffer

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 …

Comparing Data At-Rest Encryption Features for MariaDB, MySQL and Percona Server for MySQL

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 …

Porting this Oracle MySQL feature to MariaDB would be great ;-)

Oracle has done a great technical work with MySQL. Specifically a nice job has been done around security. There is one useful feature that exists in Oracle MySQL and that currently does not exist in MariaDB. Oracle MySQL offers the possibility from within the server to generate asymetric key pairs. It is then possible use [...]

Webinar 6/28: Securing Database Servers From External Attacks

Please join Percona’s Chief Evangelist Colin Charles on Thursday, June 28th, 2018, as he presents Securing Database Servers From External attacks at 7:00 AM PDT (UTC-7) / 10:00 AM EDT (UTC-4).

A critical piece of your infrastructure is the database tier, yet people don’t pay enough attention to it judging by how many are bitten via poorly chosen defaults, or just a lack understanding of running a secure database tier. In this talk, I’ll focus on MySQL/MariaDB, PostgreSQL, and MongoDB, and cover external authentication, auditing, encryption, SSL, firewalls, replication, and more gems from over a decade of consulting in this space from Percona’s 4,000+ …

Encrypting an existing MySQL/MariaDB RDS Instance

Often it is necessary to convert an unencrypted RDS instance into an encrypted one. And it is usually expected that this process is done with minimum or no downtime. Unfortunately, one can only enable encryption when the instance is created. However, there is still hope, as there are a couple of workarounds to encrypt your existing data.

In this article, I will discuss two different solutions to achieve this result.

Solution 1: Create a snapshot and copy the snapshot to a new encrypted snapshot:

  • Create a manual snapshot of the unencrypted RDS instance
  • Go to Snapshots from the left panel and choose the snapshot just created
  • From the Actions, choose Copy snapshot option and enable encryption
  • Select the new encrypted snapshot
  • Go to Actions and …

Enabling KMS encryption for a running Amazon RDS instance

Since summer 2017, Amazon RDS supports encryption at rest using AWS Key Management Service (KMS) for db.t2.small and db.t2.medium database instances, making the feature now available to virtually every instance class and type.

Unless you are running Previous Generation DB Instances or you can only afford to run a db.t2.micro, every other instance class now supports native encryption at rest using KMS. As for the Amazon documentation:

Encryption on smaller T2 database instances is useful for development and test use cases, where you want the environment to have identical security …

MySQL Security – MySQL Enterprise Transparent Data Encryption

In this sixth episode of the MySQL Security series, we will see how data-at-rest encryption helps organizations implement stronger security controls and satisfy regulatory compliance. You will be able to protect the privacy of your information, prevent data breaches and help meet popular regulatory requirements including GDPR, PCI DSS, HIPAA with MySQL Enterprise Transparent Data Encryption aka TDE.
