To prevent the plugin from being removed at runtime, add the -audit-log option under the option group in the MySQL configuration file (/etc/my.cnf) with a setting of FORCE_PLUS_PERMANENT. The value for audit_log should return ACTIVE. Verify the plugin installation by running: Shell> bin/mysql -u root -p < /usr/local/mysql/share/audit_log_filter_linux_install.sql This can be determined by running – select example if the basedir is /usr/local/mysql Run the audit_log_filter_linux_install.sql script located in the sharedirectory of your MySQL installation.
Use this process to ensure auditable events are captured:Ĭonfigure MySQL database server 8.0 for auditing and configure audit settings to include required events as part of the audit record. If no audit event is returned for the auditable actions just performed, this is a finding.Ĭonfigure DBMS auditing to audit standard and organization-defined auditable events, with the audit record to include what type of event occurred. To confirm that MySQL audit is capturing sufficient information to establish the identity of the user/subject or process, perform a successful auditable action and an auditable action that results in an SQL error, and then view the results in the audit file, whichever is in use. If there are no audit log files, then organizational auditable events are not being audited, and this is a finding. If more permissive than "750", this is a finding. Next, verify the log files have set permissions for the log_destination: Run following command to verify the directory permissions and review its output:ĭrwxr-x- _mysql _mysql 1760 Apr 26 09:55 data If they do not, this means they are in plaintext, and this is a finding. If the file is more permissive than "640", this is a finding.Ĭheck that the files end with the ".enc" file extension. If the group owner is not "mysql", this is a finding. If the user owner is not "mysql", this is a finding. Next, verify the log files have set permissions the log_destination: Run the following command using the audit log location from above and review its output:įor example, if the values returned by - "select " are /usr/local/mysql/data/, audit.log Review the audit files in the file systems.
If nothing is returned or the value for audit_log_encryption is not AES, this is a finding. WHERE VARIABLE_NAME LIKE 'audit_log_encryption' Next, determine if the audit log is encrypted: If the results are not 'audit_log' and plugin_status='ACTIVE', this is a finding. SELECT PLUGIN_NAME, plugin_status FROM INFORMATION_SCHEMA.PLUGINS
#MYSQL ENTERPRISE RULES CODE#
Verify, using vendor and system documentation if necessary, that the Database Management System (DBMS) is configured to use MySQL auditing features, or that a third-party product or custom code is deployed and configured to satisfy this requirement.Ĭheck MySQL auditing to determine whether organization-defined auditable events are being audited by the system. Oracle MySQL 8.0 Security Technical Implementation Guideĭetails Check Text ( C-38316r623411_chk ) The log contents include when clients connect and disconnect, and what actions they perform while connected, such as which databases and tables they access. When installed, the audit plugin enables MySQL Server to produce a log file containing an audit record of server activity.
MySQL provides auditing using the MySQL Enterprise Audit Log Plugin. If event type information is not recorded and stored with the audit record, the record itself is of very limited use. This requires specific information regarding the event type to which an audit record refers. It is important, for accurate forensic analysis, to know exactly what actions were performed.

Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.Īudit record content that may be necessary to satisfy the requirement of this policy includes, for example, time stamps, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked.Īssociating event types with detected events in the application and audit logs provides a means of investigating an attack recognizing resource utilization or capacity thresholds or identifying an improperly configured application.ĭatabase software is capable of a range of actions on data stored within the database. Information system auditing capability is critical for accurate forensic analysis.
