MariaDB MySQL Security

Auditing MariaDB SQL statements and events

As part of implementing NIST Cyber Security Framework at ALight Technology And Services Limited, one of the important thing to audit / log was database server. I am currently ingesting some logs into CloudWatch. In a blog post / youtube video in the future, I would show how to ingest logs into CloudWatch.

As a one person I do multiple things, now, I digged into some DBA work 🙂

This blog post is about writing audit log for MariaDB. In this blog post MariaDB Audit Plugin would be enabled and configured.

Update conf file, usually /etc/mysql/mariadb.cnf on Ubuntu, but could be different. Add the following lines under [mysqld]:

plugin_load_add = server_audit
server_audit_file_path=/var/log/mysql/mariadb-audit.log # path to the audit log
server_audit_events = 'CONNECT,QUERY,TABLE'
server_audit_file_rotate_size=1000000 # in bytes

That’s all. The variables are pretty much self-explanatory. There are few more variables that can be used. Here is a link explaining the variables: Audit Plugin Options.

plugin_load_add – loads the plugin.

server_audit – we want the plugin to be permanently activated.

server_audit_file_path – Path to the file.

server_audit_logging – ON – we want the logging to happen

server_audit_events – We are logging connection requests, queries including failed queries and the affected tables.

server_audit_file_rotate_size – Max file for log before generating new file.

server_audit_file_rotations – Number of older files to hold before deleting.

There is an option for writing into syslog, by settingserver_audit_logging = ‘syslog’ but that’s beyond the scope of current blog post and I would prefer having a seperate file instead of getting sql log mixed into syslog – Personal preference.

These steps are very important considering rogue R&AW spies equipment capabilities and the atrocities they are committing.

I don’t have any fake aliases, nor any virtual aliases like some of the the psycho spy R&AW traitors of India.
