Firewalls and routers are essential components of the architecture that control the network’s input and output. PCI DSS Requirement 1.1.3: Create valid and current card data flow diagrams showing all cardholder data streams between systems and networks. Goals PCI DSS Requirements Build and Maintain a Secure Network and Systems 1. If insecure services, protocols, or ports are required for business purposes, the risk arising from the use of these protocols should be clearly understood and accepted by the organization. Watch this video to learn more about PCI DSS Requirement 1.1.5. The goal of PCI Requirement 1.2.1 is to limit traffic to only essential, required protocols, ports, or services and have business justification for those required elements. In progressing processes without formal approval and testing of changes, the records of the changes may not be updated as desired, which can lead to discrepancies between the network documentation and the actual configuration. What is PCI Requirement 1.3.7? PCI Requirement 3.1 states that organizations should, “Keep cardholder data storage to a minimum by implementing data retention and disposal policies, procedures, and processes…” PCI Requirement 3.1 aligns with the methodology of many other PCI requirements: If you don’t need it, get rid of it. PCI DSS Requirement 1.3.3: Apply anti-spoofing measures to detect and prevent spoofed IP addresses from entering the network. Usually, a packet originally contains the IP address of the computer that sent it, so other computers on the network know where the packet originated and came from. We would love to hear from you! This applies even where there is no PAN in the environment.

Requirement 1.3 focuses on ensuring that you prohibit direct public traffic from the Internet into the Cardholder Data Environment (CDE). The level of classification defines what an organization has to do to remain compliant. Simply installing a firewall on the network perimeter doesnt make you compliant PCI DSS Requirement 1. The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard for organizations that handle branded credit cards from the major card schemes.. PCI DSS Terminology Breakdown. Properly scoping your environment is the most important initial step of becoming PCI compliant. In order to make sure that sensitive information is only accessed by authorized individuals, all processes and systems should be configured for limited access on a need to know basis. PCI DSS Requirement 1 - Install & Maintain Firewall Requirement 1: Install and maintain a firewall configuration to protect cardholder data Simply stated - Secure networks with access to cardholder data must be protected by physical (hardware) firewalls. Thought it may seem taxing at first, but it is the best way to achieve PCI DSS compliance. This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what the Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organizations needs to know and do to become compliant. What is PCI Requirement 1.2.2? PCI DSS Requirement 1: Protect cardholder data with a firewall, PCI DSS Requirement 1.1: Set and implement firewall and router configuration standards, PCI DSS Requirement 1.1.1: Create a formal process to confirm and test all network connections, changes in firewall and router configurations. Custom configuration settings must be defined. Also, a process should be created to keep the network topology diagrams current, and the network topology diagrams should be updated to indicate the changes after the changes are made. Also, the firewall and router configuration standards should indicate that firewall and router rule sets should be reviewed at least every six months. In my job as a QSA, I found my passion and worked closely with the Audit and Compliance team. PCI DSS Requirement 1.3.5: Only allow “established” connections to the network. PCI DSS Requirement 1.5: Ensure that security policies and operational procedures for managing firewalls are documented, in use, and known to all affected parties. Allowing non-trusted systems to connect to the CDE of an organization can provide access for attackers and other malicious users. Also, firewalls can be located in sensitive areas of the internal network, and the cardholder can protect the data environment by separating it from other networks of the organization. Firewalls are devices that control traffic between the local network of the organization and untrusted external networks. PCI compliance is divided into four levels, depending on the annual amount of a business process credit or debit card transactions. When firewalls do not limit the cardholder data environment and wireless network connections, malicious attackers who gain unauthorized access to the wireless network can easily connect to the cardholder data environment and steal sensitive account information. Create a documented and implemented process to confirm and test all connections and changes in firewalls and routers; it will help prevent security problems that may arise from the improper configuration of the network, router, or firewall. Do not use vendor-supplied defaults for system passwords and other security parameters Protect Cardholder Data 3. The firewall rule base must be reviewed at least quarterly and the change management process created to add and push the policy to the firewall. PCI DSS Requirements. This requirement focuses on enforcing the security and controls surrounding your organization’s firewall and router configurations. We find that most organizations struggle with the documentation aspect of a PCI assessment. In the PCI DSS a handful of terms related to passwords have been introduced over time: Authentication – Any particular method used to verify identity for access to a system or service, typically requiring one or more credentials. The requirement 4 is further broken down into 3 sub-requirements and compliance to each is a must to achieve overall PCI DSS compliance. Firewall; Network Access Control (NAC) Managed Firewall Services; PCI DSS Requirement 2. Organizations that make many changes to firewall and router rule sets can investigate more frequently if they wish to ensure that their rule sets continue to meet the business needs. Users of portable computing devices cannot change the personal firewall. All traffic from the cardholder data environment needs to be evaluated to ensure that it meets the established authoritative rules. The known or unknown use of wireless technology within a network is a common way for malicious people to access the network and cardholder data. Although unreliable connection permissions to systems located in the demilitarized zone (DMZ) are justifiable reasons, these connection permissions should never be granted to local network systems. However, Requirements 8.1.1, 8.2, 8.5, 8.2.3 through 8.2.5, and 8.1.6 through 8.1.8 are not intended to apply to user accounts within a point-of-sale payment application that only have access to one card number at a time in order to facilitate a single transaction (such as cashier accounts). Failure to adequately implement this measure may result in the organization being vulnerable to unauthorized access by malicious individuals or software. Install and maintain a firewall configuration to protect cardholder data. Compliance to this requirement is primarily a task for the IT department and it curtails all those activities that are directly or indirectly involved in storing, processing and transmitting cardholder data through the network. Firewall rule set analysis allows companies to clear unnecessary, old, or incorrect rules at least every six months and states that all rule sets contain approved services and ports only for documented business reasons. The Payment Card Industry Data Security Standard (PCI DSS) Audit reports provide available documentation and compliance artifacts that help you demonstrate compliance with requirements of the PCI DSS. The demilitarized zone (DMZ) is the part of the network that manages connections between the internet or other unreliable networks and the services that an organization needs to be public. Vulnerabilities are often caused by unused or unsafe services and ports because overlooked, non-updated services and ports often have known vulnerabilities. Goals PCI DSS Requirements Build and Maintain a Secure Network and Systems 1. Understanding these aspects of firewall configuration are vital when trying to protect your cardholder data. PCI DSS Requirement 1.1.2: Create a network topology diagram that defines all connections between the cardholder data environment and other networks, including wireless networks. All connections must be monitored, and unauthorized connections and communications must be restricted to restrict traffic to only authorized connections and communications. Requirement 1.2.3 requires that organizations install perimeter firewalls between all wireless networks and the Cardholder Data Environment. PCI DSS Requirements 1.1.2 and 1.1.3 are all about maintaining network documentation. Please fill in your details and we will stay in touch.
