Classificació del document

La classificació i seguretat dels documents és una afer important per a les empreses i governs.

Information is exchanged between users and organizations that collaborate to pursue a business goal. Where sensitive information is involved, it is assumed that the parties will have agreed what information is sensitive and how such information will be identified and handled. Any recipient of a resource will rely upon the provider of the information to follow the agreed procedures to identify the sensitivity of the information.

LibreOffice provides standardized means for such sensitivity information to be expressed and may be used between parties if interoperable systems are to be implemented. It provides a set of standard “fields” that can be used to hold sensitivity information. It does not attempt to define what the contents of these “fields” should be. This approach is an improvement upon the only alternative that exists at the moment, which is for the provider to use an arbitrary means to express sensitivity that may not be useful to a recipient.

While this standard has been developed with the intent that it would be applicable in any domain of activity, LibreOffice retained the aerospace and defense industry nomenclature and categories, where sensitivity marking results from national security, export control and intellectual property policies.

LibreOffice implemented the open standards produced by TSCP (Transglobal Secure Collaboration Participation, Inc.) independent of a specific vendor. Two of them are interesting:

Categories del BAF

Les categories del BAF incloses per defecte amb el LibreOffice s'indiquen tot seguit.

Icona de consell

Only the Intellectual Properties category will modify the layout of the document with a watermark, fields in the header and footer and an information bar on top of the document area. Each item inserted in the document is controlled by the classification configuration file.


Propietat intel·lectual

«Propietat intel·lectual» és un terme genèric per al caràcter del contingut del document. Seleccioneu aquesta categoria per a classificar documents d'ús general.

Seguretat nacional

Selects the category of this document for the national security policy type. The selected category is saved together with the document as BAILS metadata in the file properties and no modifications is carried in the document layout or the user interface.

Control d'exportació

Selects the category of this document for the export control policy type. The selected category is saved together with the document as BAILS metadata in the file properties and no modifications is carried in the document layout or the user interface.

Icona d'avís

Refer to your corporate data security policy and information security officers for support in document classification.


Nivells predeterminats de classificació

LibreOffice provides default levels of document classification (BAILS) shown below, sorted by increasing level of business sensitivity:

Personalització dels nivells de classificació.

Amb el LibreOffice és possible personalitzar els nivells de classificació perquè s'adaptin a la vostra empresa. Per a personalitzar el nombre i el nom dels nivells, copieu el fitxer example.xml que es troba a Eines ▸ Opcions ▸ LibreOffice ▸ Camins ▸ Classificació a una carpeta local i modifiqueu-ne el contingut.

Icona de consell

Feu servir com a exemple el fitxer corresponent a la configuració local de la vostra versió del LibreOffice.


Save the file and make the adequate changes to the classification path above to access the file.

Icona de consell

Your system administrator can place the file in a network folder and make all users access the classification settings file.


Pasting contents in documents with different levels of classification.

To prevent a breach in the security policy, contents with high classification level pasted to documents with lower classification level are not allowed. LibreOffice will display a warning message wherever it detects that the contents of the clipboard have higher security classification than the target document.

Barra de classificació

La barra de classificació conté eines que us ajuden en la gestió segura de documents.

The Classification toolbar contains listboxes to help in selecting the security of the document, according to the BAF category policy and BAILS levels. LibreOffice will add custom fields in the document properties (File - Properties, Custom Properties tab) to store the classification policy as document metadata.
