PCI DSS 4 0: How to Ensure Full Compliance with New Requirements Qualys Security Blog

Also called “dynamic packet filtering.” Firewall capability that provides enhanced security by keeping track of the state of network connections. Programmed to distinguish legitimate packets for various connections, only packets matching an established connection will be permitted by the firewall; all others will be rejected. Abbreviation for “Secure Shell.” Protocol suite providing encryption for network services like remote login or remote file transfer. A malicious individual executes unauthorized SQL commands by taking advantage of insecure code on a system connected to the Internet. SQL injection attacks are used to steal information from a database from which the data would normally not be available and/or to gain access to an organization’s host com puters through the computer that is hosting the database. Process of identifying all system components, people, and processes to be included in a PCI DSS assessment.

Discipline of mathematics and computer science concerned with information security, particularly encryption and authentication. In applications and network security, it is a tool for access control, information confidentiality, and integrity. Acronym for “attestation of compliance.” The AOC is a form for merchants and service providers to attest to the results of a PCI DSS assessment, as documented in the Self-Assessment Questionnaire or Report on Compliance. Elevated or increased privileges granted to an account in order for that account to manage systems, networks and/or applications. Administrative access can be assigned to an individual’s account or a built-in system account.


Acronym for “Wired Equivalent Privacy.” Weak algorithm used to encrypt wireless networks. Several serious weaknesses have been identified by industry experts such that a WEP connection can be cracked with readily available software within minutes. Network that is external to the networks belonging to an organization and which is out of the organization’s ability to control or manage.

  • In addition, businesses must restrict access to cardholder data and monitor access to network resources.
  • Adequate network segmentation may reduce the scope of the cardholder data environment and thus reduce the scope of the PCI DSS assessment.
  • Acronym for “Post Office Protocol v3.” Application-layer protocol used by e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection.
  • Includes all purchased and custom software programs or groups of programs, including both internal and external (for example, web) applications.
  • Acronym for “wireless local area network.” Local area network that links two or more computers or devices without wires.

Conversely, the cost of noncompliance, both in monetary and reputational terms, should be enough to convince any business owner to take data security seriously. Affiliate membership is open to regional and national organizations that define standards and influence adoption by their constituents who process, store or transmit payment data. The AOC requirement applies to all merchants seeking to adhere to PCI DSS, regardless of compliance level. This document is signed and submitted by the merchant or service provider if they are completeing their own questionnaire, or by an assessor in the case of merchants with the Report on Compliance requirement. Every compliance level involves some permutation of just four specific requirements.

Non-Console Access

Broad industry participation is critical to the Council’s mission to help secure payment data globally. Organizations should regularly review and update their policies and procedures, while also educating employees about the importance of PCI DSS compliance and their role in protecting cardholder data. Businesses consult with QSAs, ASVs and other experts to help assess, implement and maintain PCI DSS compliance. Standards like PCI DSS are more important than ever for protecting these businesses’ consumers and their private data. Designed around modern data privacy concerns, PCI DSS have become critical and established guidelines for enterprises dealing with more and more payment data in the cloud.

The Board of Advisors represents PCI SSC Participating Organizations worldwide to ensure global industry involvement in the development of PCI Security Standards. As strategic partners, they bring market, geographical and technical insight into PCI SSC plans and projects. A Board of Advisors, representing and elected by Participating Organizations, provides input to the organization and feedback on the evolution of the PCI Standards. Unlike the SAQ, a ROC is completed by a Qualified Security Assessor (QSA), rather than the merchant. QSAs, like scanning vendors, are third parties approved by the PCI SCC to independently assess PCI DSS compliance. The AOC is simply a declaration of the final results of any PCI DSS assessment.

Card Skimmer

Also referred to as “full track data”or “magnetic-stripe data.” Data encoded in the magnetic stripe or chip used for authentication and/or authorization during payment transactions. Can be the magnetic-stripe image on a chip or the data on the track 1 and/or track 2 portion of the magnetic stripe. Abbreviation for “telephone network protocol.” Typically used to provide user-oriented command line login sessions to devices on a network.

Network Security Scan

Software of a computer system that is responsible for the management and coordination of all activities and the sharing of computer resources. Examples of operating systems include Microsoft Windows, Mac OS, Linux and Unix. Refers to logical access to a system component that occurs over a network interface rather than via a direct, physical connection to the system component.

Instead, moving to a safer card acceptance method (like Stripe Checkout, Elements, and mobile SDKs) is a much more effective way to protect your organization. The long-standing benefit this provides is that you don’t need to rely on industry baseline standards or worry about the potential failure of security controls. This approach provides agile businesses a way to https://1investing.in/ mitigate a potential data breach and avoid the emotional, time-consuming, and costly historical approach to PCI validation. Not to mention, a safer integration method is reliable every single day of the year. A variety of questionnaires exist, so merchants and service providers must determine which of the specific forms applies to them before completing the SAQ.


As businesses — like established merchants and most large service providers — continue to move from on-premises systems to the cloud, data security in general has become an increasing concern. E-commerce and online financial services are booming alongside a rise in more sophisticated online fraud and hacking practices, a dangerous combination. Finally, level 1 compliance applies to merchants processing more than six million credit or debit card transactions annually on-site.


Process by which an entity’s systems are remotely checked for vulnerabilities through use of manual or automated tools. Security scans that include probing internal and external systems and reporting on services exposed to the network. Scans may identify vulnerabilities in operating systems, services, and devices that could be used by malicious individuals. Qualys Vulnerability Management, Detection, and Response (VMDR) – VMDR is not included with Total Compliance and is a recommended foundational solution for managing CDE cyber risks (Req. 2, 5, 6, 11). It addresses the third goal for a CDE vulnerability management program and Requirement 11’s need for regularly testing the security of CDE systems and networks. VMDR excels at detecting internal and external risks and efficiently responding to vulnerabilities.

A virtual switch or router is a logical entity that presents network infrastructure level data routing and switching functionality. A virtual switch is an integral part of a virtualized server platform such as a hypervisor driver, module, or plug-in. The VMM is included with the hypervisor and is software that implements virtual machine hardware abstraction. It manages the system‹s processor, memory, and other resources to allocate what each guest operating system requires. A process of assigning version schemes to uniquely identify a particular state of an application or software.

As such, businesses benefit from getting to know the rules around PCI DSS to ensure secure card payments online and on-site. The Payment Card Industry Security Standards Council, which is made up of members from five major credit card companies, established rules and regulations known as PCI compliance. The council is responsible for mandating compliance to help ensure the security of credit card transactions in the payments industry. The standards originally applied to merchant processing, but were later expanded to encrypted internet transactions. Those requirements, known as the Payment Card Industry Data Security Standard (PCI DSS), are the core component of any credit card company’s security protocol. These protocols are designed to secure the transmission of data, like Transport Layer Security (TLS).

Network of an organization that is within the organization’s ability to control or manage. Also referred to as “Trojan horse.” A type of malicious software that when installed, allows a user to perform a normal function while the Trojan performs malicious functions to the computer system without the user’s knowledge. Acronym for “Secure Sockets Layer.” Industry standard that encrypts the channel between a web browser and web server. In the context of web session management, a session token (also referred to as a “session identifier” or “session ID”), is a unique identifier (such as a “cookie”) used to track a particular session between a web browser and a webserver.
