PostgreSQL

:

This topic describes how to connect PostgreSQL application to PrivaceraCloud.

Prerequisites

  • Create a database in PostgreSQL and get the database name and its URL:

  • Create a database user granting all privileges to fully access the database, and then get the user credentials to connect to the database.

If you choose to enable audits for PolicySync, ensure the following prerequisites are met:

Connect application

  1. Go the Setting > Applications.

  2. In the Applications screen, select PostgreSQL.

  3. Enter the application Name and Description, and then click Save.

  4. Click the toggle button to enable Access Management for PostgreSQL.

  5. In the BASIC tab, enter the values in the given fields and click Save. For property details and description, see table below:

    Specifies whether PolicySync uses the PostgreSQL native public group for access grants whenever a policy refers to a public group. The default value is true.

    Set access control policies only on the users from managed groups

    boolean

    false

    No

    false

    No

    Specifies whether to use the data source native row filter functionality. This setting is disabled by default. When enabled, you can create row filters only on tables, but not on views.

    Enforce masking policies using secure views

    boolean

    true

    No

    Specifies whether to use secure view based masking. The default value is true.

    Because PolicySync does not support native masking for PostgreSQL, enabling this setting is recommended.

    Enforce row filter policies using secure views

    boolean

    true

    No

    Specifies whether to use secure view based row filtering. The default value is true.

    While PostgreSQL supports native filtering, PolicySync provides additional functionality that is not available natively. Enabling this setting is recommended.

    Create secure view for all tables/views

    boolean

    true

    No

    Specifies whether to create secure views for all tables and views that are created by users. If enabled, PolicySync creates secure views for resources regardless of whether masking or filtering policies are enabled.

    <MASKED>

    No

    Specifies the default masking value for text and string column types.

    Secure view name prefix

    string

    No

    Specifies a prefix string for secure views. By default view-based row filter and masking-related secure views have the same schema name as the table schema name.

    If you want to change the secure view schema name prefix, specify a value for this setting. For example, if the prefix is dev_, then the secure view name for a table named example1 is dev_example1.

    Secure view name postfix

    string

    _secure

    No

    Specifies a postfix string for secure views. By default view-based row filter and masking-related secure views have the same schema name as the table schema name.

    If you want to change the secure view schema name postfix, specify a value for this setting. For example, if the postfix is _dev, then the secure view name for a table named example1 is example1_dev.

    Secure view schema name prefix

    string

    No

    Specifies a prefix string to apply to a secure schema name. By default view-based row filter and masking-related secure views have the same schema name as the table schema name.

    If you want to change the secure view schema name prefix, specify a value for this setting. For example, if the prefix is dev_, then the secure view schema name for a schema named example1 is dev_example1.

    Secure view schema name postfix

    string

    No

    Specifies a postfix string to apply to a secure view schema name. By default view-based row filter and masking-related secure views have the same schema name as the table schema name.

    If you want to change the secure view schema name postfix, specify a value for this setting. For example, if the postfix is _dev, then the secure view name for a schema named example1 is example1_dev.

    Enable dataadmin

    boolean

    true

    No

    This property is used to enable the data admin feature. With this feature enabled you can create all the policies on native tables/views, and respective grants will be made on the secure views of those native tables/views. These secure views will have row filter and masking capability. In case you need to grant permission on the native tables/views then you can select the permission you want plus data admin in the policy. Then those permissions will be granted on both the native table/view as well as its secure view.

    Users to exclude when fetching access audits

    string

    POSTGRES_JDBC_USERNAME

    No

    Specifies a comma separated list of users to exclude when fetching access audits. For example: "user1,user2,user3".

    secure.view.name.remove.suffix.list

    string

    Specifies a suffix to remove from a table or view name. For example, if the table is named example_suffix you can remove the _suffix string. This transformation is applied before any custom prefix or postfix is applied.

    You can specify a single suffix or a comma separated list of suffixes.

    secure.view.schema.name.remove.suffix.list
