VISA Payment Card Industry (PCI) ComplianceThe new Payment Card Industry (PCI) Data Security Standard outlines best practices for credit card data that is stored, processed, or transmitted.
All major credit card issuers, including Visa, MasterCard, American Express, Diners Club, and Discover, jointly developed PCI. (It consolidates and supersedes the requirements of the previously developed Visa Cardholder Information Security Program (CISP) and the MasterCard Site Data Protection (SDP).) Most merchants are required to comply with this standard.
How does CipherOptics help? CipherOptics CipherEngine enables Secure Information Sharing, which assures the confidentiality, authenticity, and integrity of data in motion on any network. Our approach to protecting both your network and your data is to deny access to everyone, permit by exception. With that as our driving force, our solutions provide you with both encryption and authentication of all your critical information. Using powerful 256-bit AES encryption that is approved by the NSA for "sensitive" information, our security solutions authenticate networks and packets and protect data. Using the robust secure hash algorithm (SHA-1), the security gateways verify the integrity of the data, rejecting any packets that have been manipulated or altered. Secure hash can also be used to thwart unauthorized intrusion at the network level. CipherEngine's deterministic firewall feature can reject any packets that lack the proper encryption-based authentication of a trusted endpoint. This effectively turns the local network dark to all unauthenticated traffic from the outside network. CipherOptics can also help satisfy compliance requirement 3, to "protect stored data." CipherEngine protects all data on your network and authenticates anyone accessing your network; including protection of cardholder data in storage by thwarting intrusion at the network level, not at the storage level. Its deterministic firewall feature can reject any packets that lack proper encryption-based authentication. This effectively turns the storage network dark to all unauthenticated traffic from the network. Network-wide data protection is an important part of best practices - for keeping customer cardholder data confidential and for complying with PCI Data Security Standards. CipherEngine is a reliable and proven method of ensuring PCI requirements for data confidentiality, integrity, and authentication. What does CipherOptics do? CipherOptics is the leader in network-wide encryption. Offering an innovative policy and key management solution, coupled with high speed, low latency encryption technology, CipherOptics helps their customers mitigate the risk of data leakage, loss and theft over any network. Who is affected by PCI? All merchants, banks, and service providers that store, process, or transmit cardholder data must comply with the PCI Data Security Standard. This includes virtually every retail concern from the "mom and pop" retail storefront to the giant mega retailers like WalMart. Compliance validation is required for all Visa Merchant Levels 1, 2, and 3 (those processing over 20,000 credit card transactions annually) and may be required for smaller Level 4 merchants. What are the requirements of PCI? There are 12 key requirements (listed under 6 categories) that retailers must implement to be compliant: Build and Maintain a Secure Network: These security requirements apply to all "system components" which is defined as any network component, server, or application included in, or connected to, the cardholder data environment. Network components include, but are not limited to, firewalls, switches, routers, wireless access points, network appliances, and other security appliances. What are the penalties for PCI non-compliance? Merchants that fail to comply with the PCI Data Security Standard face fines of up to $500,000 and loss of the ability to accept credit cards. In August 2006, only 22% of the major retailers (approximately 290 in the United States) were PCI compliant. An even smaller percentage of mid-size and smaller retailers is compliant. How do companies comply with PCI? Encryption is a vital part of PCI compliance. Compliance requirement 4 is to "encrypt transmission of cardholder data and sensitive information across public networks." Companies should think of "public networks" as including shared, leased networks. Although service providers often refer to them as "private line" services, they are not secure. Shared, leased line services separate the data of many customers using the network, but they do not provide data security. Companies must encrypt cardholder data before sending it over third-party networks. Given the challenges of securing wireless communication, which often involves decryption at the access point, Visa tells merchants to "consider deploying it only for non-sensitive data transmission, or waiting for more secure technology." Compliance with PCI requires end-to-end encryption of wireless transmission of cardholder data and sensitive information. Companies must not only protect stored data at rest, but PCI compliance requires that stored cardholder data is encrypted when it is sent over network links to back-up storage. Whether it's for continuous data replication or electronic archival, data must be secured when it travels to offsite locations. Helpful Resources PCI Security Audit Procedures |
