Defined Approach Requirements
1.2.2.a Examine documented procedures to verify that changes to network connections and configurations of NSCs are included in the formal change control process in accordance with Requirement 6.5.1.
1.2.2.b Examine network configuration settings to identify changes made to network connections. Interview responsible personnel and examine change control records to verify that identified changes to network connections were approved and managed in accordance with Requirement
6.5.1.
1.2.2.c Examine network configuration settings to identify changes made to configurations of NSCs. Interview responsible personnel and examine change control records to verify that identified changes to configurations of NSCs were approved and managed in accordance with Requirement
6.5.1.
Customized Approach Objective
Changes to network connections and NSCs cannot result in misconfiguration, implementation of insecure services, or unauthorized network connections.
Applicability Notes
Changes to network connections include the addition, removal, or modification of a connection.
Changes to NSC configurations include those related to the component itself as well as those affecting how it performs its security function.
Defined Approach Testing Procedures
1.2.2.a Examine documented procedures to verify that changes to network connections and configurations of NSCs are included in the formal change control process in accordance with Requirement 6.5.1.
1.2.2.b Examine network configuration settings to identify changes made to network connections. Interview responsible personnel and examine change control records to verify that identified changes to network connections were approved and managed in accordance with Requirement 6.5.1.
1.2.2.c Examine network configuration settings to identify changes made to configurations of NSCs. Interview responsible personnel and examine change control records to verify that identified changes to configurations of NSCs were approved and managed in accordance with Requirement 6.5.1.
Purpose of requirement and procedures
[No detail is provided here in the PCI DSS 4.0]
Good practice
Changes should be approved by individuals with the appropriate authority and knowledge to understand the impact of the change. Verification should provide reasonable assurance that the change did not adversely impact the security of the network and that the change performs as expected.
To avoid having to address security issues introduced by a change, all changes should be approved prior to being implemented and verified after the change is implemented. Once approved and verified, network documentation should be updated to include the changes to prevent inconsistencies between network documentation and the actual configuration.

What is the PCI DSS
The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards formed in 2004 by Visa, MasterCard, Discover Financial Services, JCB International and American Express. Governed by the Payment Card Industry Security Standards Council (PCI SSC), the compliance scheme aims to secure credit and debit card transactions against data theft and fraud.
While the PCI SSC has no legal authority to compel compliance, it is a requirement for any business that processes credit or debit card transactions. PCI certification is also considered the best way to safeguard sensitive data and information, thereby helping businesses build long lasting and trusting relationships with their customers.

What is the PCI SSC
The PCI SSC mission is to enhance global payment account data security by developing standards and supporting services that drive education, awareness, and effective implementation by stakeholders. We achieve this with a strategic framework to guide our decision-making process and ensure that every initiative is aligned with our mission and supports the needs of the global payments industry.
The four pillars of our strategic framework include:
- Increase industry participation and knowledge in the PCI Standards development process and stakeholder support for standards implementation. This ensures that standards and resources reflect and address industry needs and challenges.
- Evolve security standards and validation programs to support a range of environments, technologies and methodologies for achieving security. This ensures standards and resources that support and enable safe commerce and the flexibility to use different approaches to meet those standards.
- Secure emerging payment channels via development of PCI Standards and resources to support broader payment acceptance. This enables safe commerce in new and emerging card and card-based payment channels such as mobile and internet-of-things.
- Increase standards alignment and consistency of PCI Standards to minimize redundancy and support effective implementation.
PCI DSS certification
PCI certification ensures the security of card data at your business through a set of requirements established by the PCI SSC. These include a number of commonly known best practices, such as:
- Installation of firewalls
- Encryption of data transmissions
- Use of anti-virus software
