The MySQL Server — mysqld

The MySQL D(a)emon

The Output of the MySQL Daemon
The Available Variables within the MySQL Daemon

Basic Options

  1. The ability to specify a default file from which MySQL would read information by specifying it inside of the --defaults-file parameter or specify a file that would be read after all of the default files would be by using the --defaults-extra-file parameter.
  2. Options related to certain storage engines available inside of MySQL (InnoDB being the main one): developers can change the default directory that InnoDB stores files in by specifying the --innodb-data-home-dir parameter, files can be stored in another location specified inside of the --innodb-data-file-path location, etc.
  3. The ability to set when certain operations (think opening ports, connections, etc.) would time out.
  4. The ability to log all changes relevant to a specific storage engine into a file (the option is called log-isam=filename where filename is the name of the file, and is only relevant to the MyISAM storage engine inside of MySQL.)
  5. The ability to display a default list of options and exit.
  6. The daemon also comes with operating system-specific options that are displayed at the top. For Windows, the options look like this:

Choosing Suitable Options

MySQL and Data Breaches

  1. All developers having MySQL as their database of choice should follow basic input sanitization procedures.
  2. Developers should familiarize themselves with the “defense in depth” principle: the more security layers protect their web appliactions, the harder it gets for a hacker to penetrate them.
  3. Those developers that want to take the security measures of their web applications up a notch should consider using information security services such as web application firewalls that protect web applications from attacks like SQL injection, cross-site scripting and the like or use data breach API services that protect the employees of companies from identity theft and similar attacks — web application firewalls protect web applications from aforementioned attacks, while data breach API services help protect people from identity theft and credential stuffing attacks. One does work without the other — however, protecting your web applications does you little favor if you don’t protect your online wellbeing at the same time.
  4. Developers familiar with security measures should also familiarize themselves with the OWASP Top 10 list — the OWASP Top 10 list outlines all of the most popular flaws targeting web applications, and you can bet the attackers are well versed in all of them. Familiarize yourself with those principles, then protect your web applications accordingly.
