The Payment Card Industry (PCI) has a Data Security Standard to which organizations accepting and storing credit card information must adhere. Since the Data Security Standard applies to all systems, one must do some interpretation to determine how the requirements apply to the System i (AS/400 or iSeries). While some specifications are clearly spelled out, such as the password requirements, others are defined by their intent. The Data Security Standard's intent is that the integrity of the data can be assured, that access to the data is restricted, and that the system's security scheme is configured to support this intent.
This is where the interpretation comes in. SkyView Risk Assessor compares your system's security configuration against security best practices for over 100 risk points. These include various i5/OS configuration items such as system values, user profile settings, TCP/IP configuration, guest user profiles, and more. Risk Assessor provides an explanation of the issue to allow you to determine whether the issue requires remediation. If remediation is required, Risk Assessor provides suggestions on how to start the remediation process.
Beyond Risk Assessor's helping you ensure that the system's configuration supports the intent of the Data Security Standard on i5/OS, here are some ways SkyView products address specific Data Security Standard requirements:
- Risk Assessor lists any i5/OS user profiles that have a default password along with the capabilities currently assigned to these profiles. SkyView Policy Minder can check user profile configurations to ensure no profiles have default passwords.
- The Data Security Standard requires "strong access controls." In i5/OS terms, this means that database files containing cardholder data be set to public authority *EXCLUDE. Policy Minder can help you change this setting as well as perform regular compliance checks to ensure the files remain secured appropriately. If users are specifically allowed access, this can also be included in the check.
- The Data Security Standard requires that inactive profiles be removed from the system at least every 90 days. Policy Minder can simplify the discovery and automate the removal of inactive profiles.
- Policy Minder templates can be used to regularly monitor user profile configuration to check the configuration of user profiles, ensuring profiles are created with the correct special authorities, group assignments, initial programs, auditing settings, etc. It can also flag new profiles that have been created, changed, or restored to have *ALLOBJ (security officer) authority. Further, it identifies profiles that are no longer active and should be removed from the system as well as ensures that all users' passwords are changed every 90 days.
- Using the Policy Minder system value category, you can check to ensure that the system's password composition rules are being enforced (must have a minimum length of seven characters, must contain a digit, must be changed every 90 days, can be reused only after four other passwords have been used, and locks the user out after six invalid password attempts). Policy Minder also ensures that i5/OS auditing remains active and is configured properly.
- Risk Assessor specifically addresses the i5/OS requirement for "an annual process that identifies threats and vulnerabilities, resulting in a risk assessment."
- Policy Minder documents the i5/OS implementation of the organization's security policy.
- To provide proof to auditors that you are regularly monitoring your security configuration, Policy Minder generates compliance-check reports. If the item being checked is in compliance, meaning that it meets the requirements of your policy, a one-page summary report is generated stating that the items are in compliance with the policy requirements. If an item is out of compliance, the report contains a detailed description of the discrepancy.
