3 What is PCI DSS? What is PCI DSS - Payment Card Industry Data Security Standard? Set of standards created by the PCI Security Standards Council Enforced by contract with banks that provide payment card processing Applicable to everyone who stores, processes or transmits payment card data 5/27/2016 3

4 PCI DSS Requirements High-level overview of the 12 PCI DSS Requirements Build and Maintain a Secure Network and Systems 1. Install and maintain a firewall configuration to protect cardholder data 2. Do not use vendor-supplied defaults for system passwords and other security parameters 5/27/2016 4

5 PCI DSS Requirements Protect Cardholder Data 3. Protect stored cardholder data 4. Encrypt transmission of cardholder data across open, public networks Maintain a Vulnerability Management Program 5. Protect all systems against malware and regularly update anti-virus software or programs 6. Develop and maintain secure systems and applications 5/27/2016 5

6 PCI DSS Requirements Implement Strong Access Control Measures 7. Restrict access to cardholder data by business need to know 8. Identify and authenticate access to system components 9. Restrict physical access to cardholder data 5/27/2016 6

8 PCI DSS 3.1 / 3.2 Important Dates Feb 13, 2015: PCI Announced April 15, 2015: PCI Published April 28, 2016 : PCI Announced/Published Oct 31, 2016 : PCI Retired Jan 31, 2018: PCI becomes mandatory Jan 31, 2018 : PCI s new additions go from being a best practice to a requirement June 30, 2018 : PCI Non early TLS (v1.1 or later) becomes mandatory 5/27/2016 8

9 PCI DSS 3.2 Highlights All PCI - Secure all individual non-console administrative access and all remote access to the CDE using multi-factor authentication (8.3) - Removed all note and testing procedures regarding removal of SSL/early TLS to a new Appendix A2 - Version 3.1 expires on 31 October 2016 (3.2 s new additions are a best practice until 31 January 2018) Service Providers only: - There are several new requirements that relate to Service Providers only including: Maintain a documented description of the cryptographic architecture (3.5.1) Implement a process for the timely detection and reporting of failures of critical security control systems (10.8) If segmentation is used, confirm PCI DSS scope by performing penetration testing on segmentation controls at least every six months and after any changes to segmentation controls/methods ( ) And several more Designated Entities Supplemental Validation (DESV) - Applies only to entities designated by a payment brand(s) or acquirer as requiring additional validation of existing PCI DSS requirements (Appendix A.3) 5/27/2016 9

10 PCI DSS Change Cycle 5/27/

11 Common PCI Terms 1. CHD - Card Holder Data 2. SAD - Sensitive Authentication Data 3. PAN Primary Account Number 5/27/

12 Interpretation of PCI requirements and applicability to z/os TOP PCI CHALLENGES FOR z/os 5/27/

13 Interpreting PCI DSS for z/os What is a z/os System Component? 1st Systems Programmer 2nd Systems Programmer RACF Engineer RACF Administrator Master Catalog SDSF The RACF Database Dataset Profiles APF Authorized Copies of the RACF General Resource Session Managers Datasets database Profiles LINKLIB Datasets SYS1.UADS Dataset SETROPTS Settings User ID Attributes User Catalogs WebSphere RACF CDT Group Connect Authorities RACF Database JES2 / JES3 RACF Classes Role Based Access Parmlib Datasets OMEGAMON General Resource Database Profiles Administrator Multi-User Access Systems WebSphere MQ Encryption Keys IMS Databases z/os Security Patches DFSMS Group Membership DB2 Databases System Proclibs SVC s Privileged Userids DB2 Table Trace Started Tasks CICS System Datasets RACF Exits Oracle Databases SYS1.Parmlib DB2 System RACF Classes for RACF Tables Datasets DB2 SMF Log Files IBM Comm Server IRR Prefixed Utilities IDMS System Exits Vendor Security QSA & Compliance Logging Parameters Products Officers ICSF Encryption Keys Magnetic Tape? 5/27/

14 Interpreting PCI DSS for z/os - Example PCI Deny-all Settings - Example Requirement 7: Restrict access to cardholder data by business need to know 7.2 Establish an access control system for systems components with multiple users that restricts access based on a user s need to know and is set to deny all unless specifically allowed. This access control system must include the following: PCI Testing Procedure Default deny-all settings The challenge for complying with PCI is to determine the meaning of a default deny-all setting Confirm that the access control systems have a default deny-all setting. For a RACF system, the PROTECTALL feature would be the obvious default deny-all setting However, if you stop there, you would be mis-interpreting the requirement 5/27/

15 Interpreting PCI DSS for z/os Deny-all Setting Deny-All Settings Some examples of RACF deny-all settings: Profiles - Universal Access ID(*) on an access list with READ or higher Profiles - Warning Global Access Table Inactive RACF Classes 5/27/

17 Vanguard Configuration Manager What is Vanguard Configuration Manager? Vanguard Configuration Manager Automates the Process of Testing Mainframe Security Configuration Controls to Assess their Compliance with the IBM z/os and RACF Configuration Checklist from the National Checklist Program (NCP) of the National Institute of Standards and Technology (NIST) and the Department of Homeland Security (DHS) Enhances z Systems Security by Providing Built-In Configuration Control Details Automates Testing on more than 350 z Systems Configuration Control Checks Produces Accurate Compliance Reports in Minutes 5/27/

18 How Does Vanguard Configuration Manager Address PCI DSS? Requirement 2 - Do not use vendor-supplied defaults for system passwords and other security parameters - Requirement 2.2 Develop configuration standards for all system components. Assure that these standards address all known security vulnerabilities and are consistent with industry-accepted system hardening standards Sources of industry-accepted system hardening standards may include but are not limited to: Center for Internet Security (CIS) International Organization for Standardization (ISO) SysAdmin Audit Network Security (SANS) Institute National Institute of Standards Technology (NIST). Requirement 3 - Protect stored cardholder data - See ZICS Integrated Cryptographic Service Facility section 5/27/

19 How Does Vanguard Configuration Manager Address PCI DSS? Requirement 5 - Protect all systems against malware and regularly update anti-virus software or programs - Since Malware on z/os is concerned with mainly gain access to APF libraries, check ACP00060 validates only appropriate Users have access Requirement 7 - Restrict access to cardholder data by business need to know - As well as specifying how Datasets and General Resources are to be protected, Vanguard Configuration Manager also controls what Roles are allowed to have access and what level of access Requirement 8 - Identify and authenticate access to system components - Reporting See RACF - Security Server (RACF) Settings section» Password Format» Password Attempts» Password Expiration See ZUSS UNIX System Services See AAMV - Inactivity Timers 5/27/

Prevents execution of z/os Security Server commands that do not comply with organizational-defined policies Enables enterprises to precisely control which users can execute specific commands, parameters and sub-parameters. Noncompliant commands are modified to comply with policy or prevented from executing. Enhanced logging features are provided to log command events regardless of resource-level or system-level audit settings 5/27/

28 Staying Compliant Continuous Monitoring Tools-Intrusion Prevention 1. User issues a supported RACF command Vanguard Policy Manager TM Continuous Monitoring and Policy Enforcement of RACF Commands: a) Validates that the command issuer is authorized to issue the command b) Validates that the command is compliant with user-defined policies c) Modifies commands to comply with written policies prior to execution d) Fails non-compliant commands (e.g. unauthorized changes to the PCI.CREDIT.DATA profile) e) Log all command activity to System Management Facility (SMF) 5/27/ PCI PCI PCI
