    Discover the Latest Security Features of IBMi RCAC

    Have you heard of the latest security features of IBMi RCAC?

    Every data resource is susceptible to theft or tampering in today’s hacker-infested world. Data protection can be expensive but being hacked is even more so.

    This is where the AS400 iSeries Row and Column Access Control (RCAC) comes in!

    IBMi RCAC is essential because several companies are looking for effective solutions to regulate security, specifically database security.


    IBMi RCAC enables database security managers to restrict who can access information in the database. Even better is that most of these security features can be enabled without requiring any changes to the software applications themselves.

    In this blog, you will learn why it is necessary to use IBMi RCAC and the several benefits it offers.

    Why Use Row and Column Access Control?

    Data must be protected in every business firm, and only users authorized to access that data should be able to access it. Based on the employment position, several information segments should not be accessible.

    Of course, one could apply SQL Views to a database, but this needlessly complicates and notifies users that there may be information that is not available. It also increases the difficulty of maintaining the database.

    Application logic could be employed, but it has a host of problems. However, a person might walk inside the tables and see all restricted data with either views or access permissions.

    This is not a good situation!

    Consequently, for ease of usage and implementation, we require Row and Column Access Control.

    Ways to implement RCAC

    Several older business application software was not designed with field security in mind. GDPR, CCPA, and other data security regulations emphasize the necessity for a much stronger data protection structure.

    RCAC permits a specific and accurate extension of this protection, restricting access to critical information without drastically rearranging user authorization.

    Furthermore, the initial query does not produce an error notification when authorization for a specific row or column is prohibited. Instead, asterisks are displayed. This feature ensures that the IBM iSeries application that authenticates this data continues to function appropriately; only access to protected data is affected.

    As a consequence, RCAC authorizations allow for more targeted accessibility.

    It implies that IBMi RCAC authorizations give a tailored solution for safeguarding sensitive data that does not necessitate extensively altering existing software applications.

    Implementing a new database storing orders stripped of detailed financial information and then upgrading the software to use the new table is one strategy for keeping this data secure.

    However, this strategy is more time-consuming and expensive than implementing some RCAC protections in general.

    Secure authorization to a few financial data sectors provides a clear approach for data security in this situation. And it does it without invalidating a presumably complex set of authorizations for marketing, finance, and customer support.

    This ability to protect specific information without compromising software performance opens up new possibilities for companies seeking to optimize data security without completely redesigning data access.

    As a fully integrated business technology platform, the IBM AS400 iSeries provides a compelling business model for companies seeking a decreased operational workload for IT systems.

    RCAC is appropriate for this sort of an operation since it enables a single admin to set up control quickly and easily without affecting the absolute reliability of the system.

    The IBMi RCAC implementation is intended to address where modifying data access rights for mission-critical applications can be complicated and time-consuming.

    How does IBMi RCAC Works?

    The security capabilities of IBMi RCAC become available after installing the free IBM advanced data security module:

    • Users appointed as database administrators can grant row and column-level authentication.
    • Permissions could be focused on single users or group profiles for role-based management.
    • Authorization can also be tied to conditional changes like:
      • Permissions can also be linked to conditional variables like the number of days or weeks since a particular row was entered.
      • An account’s overall size.
      • Status of an order.
    • The same database table can have unlimited criteria, allowing for overlapping regulations.

    Advantages of Using Security Features of IBMi RCAC

    Initially, only menu or option level security was supported and enabled by AS400 iSeries software applications. It essentially means that only certain menus or functionalities could be accessed.

    Advantages of Using Security Features of IBMi RCAC

    However, once a user gets access to a specific system section, no additional specific controls could be enforced without major software application changes.

    • User permissions were maintained exclusively through table-level authorization in previous versions of IBMi, but this degree of access control expanded over time to the database layer. A user would either have complete or partial access to the data in a table.
    • IBMi RCAC offers far more granular controls that can be used to augment table-level rights on a case-by-case basis. It allows IBMi access control to be expanded and enforced to individual rows and columns.
    • This feature uses SQL rules implemented directly at the database layer. When a query is made to the database, ground-level permissions are verified. If the question originates from an IBMi application software or a third-party system, it makes no difference.
    • If the user with authorization does not have access to a specific row or column, their query will not yield any information from these protected sections.
    • The row and column access control rules apply to every database user by default. These regulations apply to even higher-level authorities, such as users with data access authorization.
    • Only users with security administrator privileges can handle or supervise row and column access controls within a system. As a result, you can employ security features of IBMi RCAC to prevent Data Access authority users from freely viewing all information from the database.
    • Irrespective of how a database is accessed via SQL, database information is safeguarded. RCAC regulations apply to software applications, upgraded analytic tools, and report generation tools. The implementation is data-driven.
    • The security features of IBMi RCAC provide an added layer of data protection. No updates to the application are required to benefit from it. Access controls are developed and defined at the row and column levels in a method that is not noticeable in existing programs.
    • IBMi RCAC, on the other hand, marks a major fundamental shift in the respect that it is no more about what is being inquired but rather who is inquiring what. The response ranges for the same query differ depending on the context in which the inquiry was made. The solution’s exact goal is reflected in this outcome.

    It means that app developers and database administrators must be aware that, unless given certain rights, inquiries don’t see the complete overview of the information in the database.
