Published on : 18 Mar 2024


PCI DSS Requirement 12

Welcome to our latest blog post where we delve into the intricacies of the Payment Card Industry Data Security Standard (PCI DSS) Requirement 12. This requirement, which focuses on maintaining an Information Security Policy, is a cornerstone of the PCI DSS framework. It outlines the need for comprehensive policies and programs that govern and provide direction for the protection of an entity’s information assets. 

In this post, we will explore the changes introduced in the latest version, v4.0, and how they compare to the previous version, v3.2.1. From acceptable use policies for end-user technologies to managing risks associated with third-party service provider relationships, we will provide a detailed explanation of each section under Requirement 12. check out our comprehensive guide on the “12 requirements of PCI DSS.”

Whether you’re a full-time employee, a part-time worker, a temporary employee, a contractor, or a consultant with security responsibilities, this post will help you understand your role in protecting account data and the security implications of your actions. So, let’s dive in and unravel the changes from v3.2.1 to v4.0 in PCI DSS Requirement 12. 

Requirementv3.2.1 (12.4) v4.0 (12.1.3)Changes
Core RequirementSecurity policies must define information security responsibilities for everyone. Identical core requirement. No Changes.
Awareness Implies personnel awareness of responsibilities.It explicitly requires that personnel are aware of and acknowledge their responsibilities. Increased emphasis on awareness and accountability.
Testing Procedures Focuses on policy review and interviewing personnel to check understanding. Maintains policy review and interviews but adds verifying documented evidence of personnel acknowledgment. Stronger focus on formal processes and evidence.

PCI DSS v4.0 mandates active acknowledgement of security roles and responsibilities by personnel and requires documented evidence of this acknowledgement. 

Requirement v3.2.1 (12.5) v4.0 (12.1.4) Changes
Scope Requires formal assignment of overall information security responsibility and assignment of specific information security tasks.Focuses on the formal assignment of overall information security responsibility. Narrowed focus.
Responsibility Responsibility could be assigned to a "Chief Security Officer or other security-knowledgeable member of management". Explicitly states responsibility must lie with a "Chief Information Security Officer or other information security knowledgeable member of executive management."Emphasizes executive-level ownership.
Testing Procedures Focuses on verifying formal assignment of various responsibilities through policy and procedure review. Simplified testing by focusing solely on policy review for executive-level assignment. Streamlined testing.

PCI DSS v4.0 mandates that a CISO or equivalent executive owns overall information security, removes focus on individual tasks, and verifies executive responsibility through policy review. 

Requirement v3.2.1 (12.3) v4.0 (12.2.1)Changes
Scope Broadly focuses on usage policies for "critical technologies", which include wireless, remote access, laptops, tablets, etc. Narrows focus specifically on "end-user technologies".Makes scope more explicit.
Policy ElementsExtensive list: explicit approval, authentication, device lists, ownership tracking, acceptable use/locations, approved products, session disconnects, vendor access controls. Streamlined list: explicit approval, acceptable uses, approved tech list (hardware/software).Simplified policy requirements.
Testing Procedures Focuses on verifying the existence and implementation of the detailed policy requirements.Focuses on verifying that the simplified policy elements are documented and followed.Less prescriptive testing.

PCI DSS v4.0 refines technology usage policies by emphasizing applicability to commonly used technologies, reducing mandatory policy elements, and focusing on core element verification rather than specific details. 

Requirement v3.2.1 (12.3.10) v4.0 (3.4.2) Changes
Core ConceptLimiting the possibility of cardholder data being copied/moved to local drives when accessed remotely.Same core concept. No Changes.
Policy vs Technical Focus v3.2.1 focuses on having a documented policy prohibiting copying/moving, with an exception for authorized use.Shifts to explicitly requiring technical controls to prevent copying/moving by default, with authorized exceptions possible. Focus on proactive prevention.
Authorized Exceptions Requires documented business need and data protection even for authorized copying/moving.Maintains the need for authorization, business justification, and lists of approved personnel.Similar approach for handling exceptions.
Testing Procedures Focuses on policy review and verifying the policy aligns with PCI DSS requirements. Includes policy review but focuses on verifying technical controls and interviewing personnel to confirm practice aligns with authorization.Emphasizes real-world controls.

PCI DSS v4.0 enhances remote access data protection by mandating technical controls as default, maintaining authorization for exceptions, and emphasizing the use of technical controls in line with authorizations. 

Requirement v3.2.1 (12.11) v4.0 (12.4.2) Changes
Core RequirementQuarterly reviews to confirm personnel follow security policies and procedures. Increases frequency to "at least once every three months" and adds requirement for reviews to be done by someone other than the person normally performing the task.More frequent, independent reviews.
ScopeSpecific list of tasks to be included in the reviews. Maintains the same list of tasks. No changes.
Documentation Requires documenting review results and sign-off by those responsible for PCI DSS compliance. Adds the requirement to document any remediation actions taken based on review findings. Focus on fixing issues, not just finding them.
Testing Procedures Focuses on policy review, interviewing personnel, and examining review records. Similar focus but adapted for the increased review frequency. Minor adjustments for frequency.

PCI DSS v4.0 enhances personnel compliance oversight in service providers by mandating tri-monthly reviews, requiring independent reviewers, and focusing on documenting required remediations. 

Requirementv3.2.1 v4.0 (12.5.1)Changes
Core RequirementHaving a system components inventory was implied as part of overall documentation practices. Explicitly requires an inventory of system components within the scope of PCI DSS, along with their function/use. Increased clarity and specificity.
Location No specific location within PCI DSS requirements. Requirement is now placed within Section 12.5, which focuses on documenting and validating the scope of PCI DSS compliance efforts. Better organization and context.
Testing ProceduresImplied you'd check this as part of general documentation review and personnel knowledge Specific testing steps focused on verifying the inventory's existence, completeness and that it's kept up to date.More focused testing guidance.

PCI DSS v4.0 enhances in-scope system component inventory management by making it an explicit requirement with detailed contents, organizing it within the PCI DSS scope context, and providing specific guidance for verifying inventory accuracy and maintenance.

Requirement v3.2.1 (12.6) v4.0 (12.6.1)Changes
Core RequirementImplement a security awareness program covering cardholder data security policies and procedures for all personnel. Emphasizes that the program must cover the entity's broader information security policy and each person's role in protecting cardholder data. Slightly broadened scope.

Requirement v3.2.1 (12.8)v4.0 (12.8)Changes
Terminology Uses the term "service provider" Shifts to "third-party service provider" (TPSP) for clarity. More specific language.
List of TPSPs Requires keeping a list with a description of services provided. Same core requirement.No changes.
Written Agreements Requires acknowledgments within the agreement that the service provider is responsible for cardholder data security.Maintains this requirement.No changes.
Due Diligence Requires an established process for engaging service providers with due diligence. Maintains this requirement.No changes.
Compliance Monitoring Requires a program to monitor service providers' PCI DSS compliance annually.Maintains this requirement but changes the frequency to at least every 12 months.Minor change to monitoring interval.
Responsibility Tracking Mandates keeping track of which PCI DSS requirements are managed by the service provider vs. the entity. Maintains this requirement. No changes.
Testing Procedures Focuses on verifying the existence of policies, agreements, and processes that are followed.Maintains a similar focus. No major changes.

PCI DSS v4.0 revises third-party relationships by replacing “service provider” with “third-party service provider” for clarity and shifting annual PCI DSS compliance monitoring of TPSPs to at least every 12 months.

Requirement v3.2.1 (12.10.1)v4.0 (12.10.1) Changes
Triggering Event Focuses on a "system breach" or "compromise".Shifts language to "suspected or confirmed security incident", expanding the scope of what triggers the plan. Broadened scope.
Plan Elements Lists required elements of the plan. Includes analysis of legal requirements, like regional data breach notification laws (California example provided).Maintains the same core elements of the plan. No changes.
Testing Procedures Focus on verifying the plan has the necessary components and that past incident responses aligned with the documented plan.Maintains a similar focus. No major changes.

PCI DSS v4.0 broadens the incident response plan scope to include a wider range of security incidents, not just breaches or compromises.
