Authentication Mechanisms: Any device that identifies a user with something only the user has, such as a physical security token or smart card.

Cardholder Data (CHD): Any personally identifiable information (PII) associated with a person who has a credit or debit card. Cardholder data includes the primary account number (PAN) along with any of the following data types: cardholder name, expiration date or service code. The term cardholder data is interchangeable with payment card data throughout this policy.

Cardholder Data Environment (CDE): Is a computer system or networked group of IT systems that processes, stores and/or transmits cardholder data or sensitive payment authentication data. A CDE also includes any component that directory connect to or supports this network.

Center for Internet Security (CIS): Global IT community to safeguard public and private organizations against cyber threats.

Common Weakness Enumeration/SysAdmin, Audit, Network and Security (CWE/SANS): Guidelines for dealing with the most critical software vulnerabilities.

Cross-shredding: Cutting into small "particle" pieces that renders the inability to reconstruct the document or media in readable form.

Cryptography: Cryptography involves creating written or generated codes that allow information to be kept secret. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without unauthorized entities decoding it back into a readable format, thus compromising the data. Information security uses cryptography on several levels. The information cannot be read without a key to decrypt it. The information maintains its integrity during transit and while being stored. Cryptography also aids in non-repudiation. This means that the sender and the delivery of a message can be verified.

Digital Certificate: A digital certificate is an electronic document which uses a digital signature to bind together a public key with an identity — information such as the name of a person, organization, and other attributes which uniquely identify the entity and their role. The certificate can be used to verify that a public key belongs to the entity claiming that identity.

DMZ: In computer security, a DMZ or demilitarized zone is a physical or logical sub-network that contains and exposes an organization's external-facing services to an untrusted, usually larger, network such as the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN). An external network node can access only what is exposed in the DMZ, while the rest of the organization's network is fire-walled.

Encryption Key: Specifies the transformation of plain-text into cipher-text, and vice versa for decryption algorithms. Keys also specify transformations in other cryptographic algorithms, such as digital signature schemes and message authentication codes.

Firewall: Network security system that monitors and acts on incoming and outgoing network traffic based on predetermined security rules.

Generic/Shared user ID: Authentication credentials assigned for one specific role that can be used by more than one person.

Operation System (OS) injection: Shell injection that allows attacker to execute arbitrary code on an operating system.

Payment Card Industry (PCI) Workstations: Any device that is connected to the cardholder data environment and handles cardholder data.

Personal Firewall: Software on a computer, usually a standalone system, designed to limit inbound and outbound connections.

PIN Transaction Security (PTS) Devices: Device used by a merchant at the point-of-interaction for capturing payment card data and validating approval of its use for a transaction.

Point-to-point encryption (P2PE): Encryption standard that requires encryption of payment card data immediately upon use with the merchant’s point-of-sale terminal and cannot be decrypted until securely transported to and processed by the payment processor.

Primary Account Numbers (PAN): A 14, 15- or 16-digit number generated as a unique identifier designated for a primary account.

Pulping: Crushing paper into soft, shapeless mass.

Remediation: The three (3) primary methods of remediation are (1) installation of a software patch, (2) adjustment of a configuration setting and (3) removal of affected software.

Sanitization: Process for deleting sensitive data from a file, device or system or for rendering data useless if accessed by unauthorized or malicious parties.

Secure Wipe: Also called secure delete, this is a program utility used to delete specific files permanently from a computer system.

Simple Network Management Protocol (SNMP) community strings: User ID or password that allows access to system components.

Stateful Inspection: A firewall that tracks the operating state and characteristics of network connections traversing it. The firewall is configured to distinguish legitimate network packets for different types of connections. Only packets matching a known active connection are allowed to pass the firewall. In contrast a stateless firewall does not take context into account when determining whether to allow or block packets. 

Structured Query Language (SQL): The standard language for relational database management systems.

SysAdmin Audit Network Security Institute (SANS): Private U.S. for-profit company founded that specializes in information security, cyber-security training and selling certificates.

Threats: Threats are capabilities or methods of attack developed by malicious entities to exploit vulnerabilities and potentially cause harm to a computer system or network. Common examples are scripts, worms, viruses and Trojan horses.

Trusted Key: Provides consumers and organizations with a secure digital identity solution. It offers financial institutions with secure and frictionless know-your-client solutions, password-less authentication systems, and enhanced document signing procedures.

Untrusted Network: For purposes of PCI, an untrusted network is a network situated outside the security perimeter and control of the CDE.

VOIP: Voice over Internet Protocol, also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol networks, such as the Internet.
