\"PCISearchSecurity.TechTarget.com recently reported on the PCI SSC (Payment Card Industry Security Standards Council) and their first annual PCI Community Meeting to discuss the changes made in PCI DSS 3.0 that affects merchants, ecommerce and retailers that deal with credit cardholder data.<\/p>\n

In an interview with PCI SSC Gen. Manager Bob Russo and their CTO (Chief Technology Officer) Troy Leach, they highlight the most-discussed proposed changes at the meeting, including the pain points of PCI compliant hosting<\/a> outsourcing and integrating with different vendors:<\/p>\n

To that point, one of the areas we see failures is, for example, where a merchant will have good intentions to meet the requirements, but then they merge with another company, the professionals in charge of PCI change roles and new IT administrators and senior managers come in. All the while they don’t think anything has changed, but the necessary network monitoring activity is no longer being done, or more people than necessary have access to admin passwords that should have been revoked. – PCI SSC CTO, Troy Leach<\/span><\/p><\/blockquote>\n

Communication and strategic planning with the PCI requirement matrix is key to avoiding gaps in security. Organizations can still take advantage of outsourcing benefits, like reduced cost and system management time, but only if partnering with a client-focused PCI compliant host that clearly defines roles and responsibilities when it comes to compliance and data security.<\/p>\n

Leach also notes that the council’s ‘business as usual’ practices have been well-received. These practices are detailed guides to implementing the standards, and published in a document called Navigating PCI DSS<\/em>. This is a great document that really explains both the technical side and the reasoning behind the requirement – including specifically how hackers can take advantage of systems that lack the required security technology.<\/p>\n

One example is the PCI requirement:<\/p>\n

2.2.1 Implement only one primary function per server to prevent functions that require different security levels from co-existing on the same server. (For example, web servers, database servers, and DNS should be implemented on separate servers.)<\/p>\n

Note: Where virtualization technologies are in use, implement only one primary function per virtual system component.<\/p><\/blockquote>\n

Their guidance\/reasoning for this standard is to ensure your system’s configuration standards and related processes address server functions that need to have different security levels, or that may introduce security weaknesses to other functions on the same server. An example is a database sharing a server with a web application would put the database at risk since the web app needs to be open for Internet traffic.<\/p>\n

Another example is the PCI requirement:<\/p>\n

3.4.1 If disk encryption is used (rather than file- or column-level database encryption), logical access must be managed independently of native operating system access control mechanisms (for example, by not using local user account databases). Decryption keys must not be tied to user accounts.<\/p><\/blockquote>\n

The SSC explains the characteristics of disk encryption<\/a>, including the fact that disk encryption encrypts data in mass storage and automatically decrypts data when a user requests it. Disk encryption also intercepts OS read and write operations, and supplies data after a password is entered by the user. Therefore, they require that the disk encryption method can’t have a direct association with the OS, or it cannot have decryption keys associated with user accounts.<\/p>\n
