1335

Number of SAP users with password expiration

1340

CATALOG READ privilege granted to current user

1360

SQL: “HANA_Security_MiniChecks” returns potentially critical issues (C = X).

To analyze security topics which tools are there?

In SAP 1969700 the following analysis commands are available:

SQL statement

Details

SQL: “HANA_Security_CopyPrivilegesAndRoles_CommandGenerator”

From one grantee to another to copy privileges and roles GRANT commands are generated

SQL: “HANA_Security_GrantedRolesAndPrivileges”

Roles and privileges granted to roles and users are displayed(via roles either directly or indirectly)

SQL: “HANA_Security_MiniChecks”

In the SAP HANA Security Check List a subset of provided checks and from the expectation the deviations are marked as potentially critical is executed by this command(C = X).

SQL: “HANA_Security_Roles”

Overview of defined SAP HANA roles

SQL: “HANA_Security_Users”

Overview of SAP HANA users and schemas

Information about security related topics is provided by the following monitoring views and dictionary tables:

  • EFFECTIVE_APPLICATION_PRIVILEGES
  • EFFECTIVE_PRIVILEGES
  • EFFECTIVE_PRIVILEGE_GRANTEES (SAP HANA >= SPS 12)
  • EFFECTIVE_ROLES
  • EFFECTIVE_STRUCTURED_PRIVILEGES
  • GRANTED_PRIVILEGES
  • GRANTED_ROLES
  • PRIVILEGES
  • ROLES
  • STRUCTURED_PRIVILEGES
  • USERS
  • Explain the CATALOG READ privilege effect

    In SAP HANA dictionary tables (e.g. TABLE_COLUMNS or INDEXES) to what extent a user can access data is controlled by CATALOG READ. All information is visible if CATALOG READ is granted. The information for own objects only is shown if CATALOG READ is not granted. Due to the required security checks at the same time the performance can be worse for these dictionary queries.

    A missing CATALOG READ right does not result in an error unlike on other databases; the result set of dictionary queries is just restricted.
