Administrator Interface

This package has no administrator interface. All data privacy protection rules must be added via the system configuration and executed by a console command.

Note

This feature is only available to On-Premise customers. If you are a Managed customer, this feature is taken care of by the Customer Solutions Team in OTRS. Please contact us via support@otrs.com or in the OTRS Portal.

System Configuration Settings

For security reasons, this package does not come with any pre-configured rules. Therefore the functionality does not work out-of-the-box and the rules must be configured by an administrator first.

To add a rule configuration:

  1. Go to the System Configuration screen of the administrator interface.

  2. Select OTRSDataPrivacyProtection in the Navigation widget.

  3. Navigate to Core → OTRSDataPrivacyProtection in the navigation tree.

  4. Add a rule configuration in YAML format to setting OTRSDataPrivacyProtection::RuleConfiguration.

The configuration of the individual rule sets are stored in YAML format and consists of the five options. The options marked with an asterisk are mandatory.

RuleName *

This string option has to be unique for all rules. It is a string, that is used to identify every different rule. The rule name appears in all related outputs and history entries, but does not affect any functionality.

RuleSource

This string option is just for informational usage. Different countries and regions have different types and kinds of data protection regulations, that might be part of laws and/or written papers. To identify the related original sources, the different configured rules are based on. RuleSource can be used to add names and/or descriptions, that will be added to related history entries (if available).

RuleType *

This string option describes the action, that will be executed on all objects, that were found during a search. The following actions are supported (in short format or in long format):

Anonymization or PrivacyByAnonymization

The anonymization rule type is used to anonymize data sets, as identified in the data classification fields. Anonymization means, that the different fields will be replaced by a string Anonymized.

Warning

During anonymizations, the original data sets are replaced by the mentioned string in the database. The original data is not saved and is therefore irretrievably lost!

Pseudonymization or PrivacyByPseudonymization

Like the anonymization, the pseudonymization rule type is used to remove the related data from their original fields. There is a major difference to the Anonymization rule type, as the data will be stored in a separated database table, called data_pseudonymization.

This table is not used by any other sub-system, and it is not usable via the GUI. It acts as a backup table, that can be (manually) searched by any administrator, that has access to the database or using the SQL Box module of the administrator interface.

During pseudonymizations, a universal unique identifier (UUID) will be created for the related data field, which is used to identify the original data later. The original data will then be copied to the backup table, using the UUID as the field identifier. Afterwards the original data will be replaced by just the UUID, which is effectively the same as an anonymization, but including a pointer to the stored original source data.

Deletion or PrivacyByDeletion

The deletion rule type is used to delete data sets, as identified in the data classification fields. Deletion means, that the different fields will be replaced by a string Deleted. Technically the original data will be deleted, as it will be replaced with a non-sensitive string, it therefore works equal to the Anonymization rule type.

Warning

During deletions, the original data sets are replaced by the mentioned string in the database. The original data is not saved and is therefore irretrievably lost!

DataClassification *

This list option is used to identify the data types for which the associated actions are to be applied. It contains the different fields of any data object as an array. Every object drivers provides a list of possible data classification fields, that might be used.

See also

The specific fields are described in the Drivers section below.

ObjectFilter *

This list option implements the search and filter criteria for every used driver. Every driver provides a list of possible search and filter options, that are allowed to be used.

See also

Please see the Drivers section below for more detailed information.

The different types of information represented by objects (e.g. ticket, customer user, etc.) are called object types within this package. Therefore we are talking about object types.

The modules implemented for the specific data processing, search functions and verification of such specific object types are called drivers or driver objects.

Rule Execution

Once the rules have been defined, they can be applied to the existing data sets. There is a console command Maint::DataPrivacy::Execute for this.

Execute the console command with the --help option for more information:

otrs> /opt/otrs/bin/otrs.Console.pl Maint::DataPrivacy::Execute --help

This command essentially offers three different options:

  • Checking the integrity and validity of the existing rules.

  • Test execution of existing rules without changing data records.

  • Execution of the existing rules, whereby the matching data sets are permanently changed.

The validation checks all available rules in the context of the affected drivers and object types. If certain options are missing or incorrect, the rule is declared invalid and execution is skipped for all drivers.

For security reasons, the validity of the corresponding rules is implicitly checked both before each dry run and before each execution and is either completely stopped or skipped in case of errors.

Warning

We recommend, that new rules or significant changes should be executed on test systems first to ensure that no data is accidentally changed or deleted.

Warning

We recommend that you back up the database first to ensure that untested data is not lost after rules or rule changes are executed.

Warning

Since rules are designed to change or completely delete data, it is very important to carefully check all rules in advance and execute the test runs for each rule change.

The console output of rule executions can be redirected into files to preserve the modified objects. Please see the following example:

otrs> /opt/otrs/bin/otrs.Console.pl Maint::DataPrivacy::Execute --execute-detail > rule-execution.txt

Drivers

This section describe the configuration and usage of the various drivers. In addition, this section contains sample configurations that can be copied and customized to your personal needs.

Customer Company Driver

All possible object filter parameters can be used to filter tickets and articles. Most of the attributes can be single strings or array references, like:

TicketNumber: 123546
TicketNumber:
  - 123546
  - 123666
Title: SomeText
Title:
  - SomeTest1
  - SomeTest2
States:
  - new
  - open
StateIDs:
  - 3
  - 4

The corresponding YAML code could look as follows:

RuleName: My Explanation Rule
RuleType: PrivacyByDeletion
RuleSource: GDPR
DataClassification:
  Ticket:
    - CustomerUserID
    - CustomerID
ObjectFilter:
  Ticket:
    Queue:
      - Junk
      - Raw
    Services:
      - Service A
      - Service B

This rule would find all tickets, that are located in the queue Junk or Raw and which have the service Service A or Service B assigned. The fields CustomerUserID and CustomerID would be deleted.

There are several possible filter parameters, regarding relative times and dates, like:

- ArticleCreateTimeOlderMinutes
- ArticleCreateTimeNewerMinutes
- ArticleCreateTimeNewerDate
- ArticleCreateTimeOlderDate

A filter like *\*TimeOlderMinutes* means older than X minutes.

The following statement would mean: all tickets, that have a CreateTime older than one day (1440 minutes).

TicketCreateTimeOlderMinutes: 1440

The following statement would mean: all tickets, that have a CreateTime newer than one day (1440 minutes).

TicketCreateTimeNewerMinutes: 1440

This is principal valid for all filter parameters with this syntax.

For more descriptions about the single search parameters, check the TicketSearch() in API reference.
