I recently stubmbled upon this website that hosts a publicly available Oracle RDBMS instance running Oracle v2.3.2, which according to this Wikipedia article is the first commercially available version of Oracle.

The new protocol dissector for X Protocol in MySQL was just merged to the master branch in Wireshark.

The internet has changed to a place where most protocols like HTTP etc now use secure connections with TLS by default.

This is a follow-up for MySQL GTID tags and binlog events, but you don’t need to read that first.

Introduction Query Attributes are a relatively new feature of the MySQL Protocol.

MySQL 8.4 and newer have extended the Global Transaction ID (GTID) functionality with a new “tag” option.

In this post I will talk about release management with MySQL as example.

This story starts with a pull request for go-mysql to allow setting the collation in auth handshake that I was reviewing.

The MySQL Protocol is the network protocol that is used between a MySQL server and a client.

The code for this tutorial is available here.

I've updated the bug tide graph I made in 2016 with today's data.

Oracle recently announced a new authentication plugin: caching_sha2_password.

In conversations about SSL/TLS people often say that they either don't need TLS because they trust their network or they say it is too slow to be used in production.

Backup traffic After securing application-to-database and replication traffic, you should also do the same for backup traffic.

The mysql_sha256_password doesn't use the nonce system which is used for mysql_new_password, but instead forces the use of RSA or SSL.

In my previous blogs I told you to enable SSL/TLS and configure it to check the CA.

In my previous blogs I told you to enable SSL/TLS and force the connection to be secured.

Intro In my previous blog post I told you to use SSL/TLS to secure your MySQL network connections.

Intro In a set of blog posts I will explain to you how different attacks on the network traffic of MySQL look like and what you can do to secure your systems againt these kinds of attacks.

Running out of disk space is something which, of course, should never happen as we all setup monitoring and alerting and only run well behaved applications.

The mysql client is a tool which I use every day as a DBA.

In a recent labs release a new feature was introduced by Oracle, or actually two very related new features were introduced.

The issue On 12 September 2016 (three days ago) a MySQL security vulnerability was announced.

On the MySQL Bugs website there are some tide stats available.
