The Payment Card Industry Security Standards Council (PCI SSC) maintains, evolves, and promotes Payment Card Industry standards for the safety of cardholder data across the globe. The PCI SSC provides organizations with technical and operational requirements for organizations accepting or processing payment transactions, and for software developers and manufacturers of applications and devices used in those transactions.
The Payment Card Industry Data Security Standard (PCI DSS) helps entities understand and implement standards for security policies, technologies, and ongoing processes that protect their payment systems from breaches and theft of cardholder data. The standards have historically been revised on a 2-3 year cycle, but the PCI SSC is transitioning to a posture of revising the PCI DSS as required based on changes to the current threat landscape. The current standard revision is PCI DSS Version 3.2 released in April 2016. Any organization that handles payment card information has to comply with the PCI DSS and must demonstrate compliance annually. Tenable Tenable.sc Continuous View (CV) is able to help organizations monitor ongoing PCI DSS compliance by integrating with Tenable Nessus, Tenable Nessus Network Monitor (NNM), and Tenable Log Correlation Engine (LCE).
The PCI Asset Management dashboard provides security teams with detailed insight into their network and PCI security posture. Vulnerabilities and events are filtered to identify operating systems, new hosts, and unsupported products. Detailed information about patch rates and remediation opportunities is presented. Indicator matrices alert to the presence of specific device types and unsupported operating systems. By effectively managing and monitoring assets on the network, security teams can better ensure network integrity and security.
Analysts get a focused view of the organization with identification of operating systems, unsupported software, and newly discovered hosts. The information provided with the data in this dashboard gives insight into the network and helps analysts assess the current PCI security posture. With an up-to-date and accurate continual assessment of the organization, analysts can be proactive in identifying issues such as shadow IT. Organizations that use Tenable.sc CV along with Nessus, NNM and LCE can greatly benefit from a continuous view across all sensors to be aware of the changes to the organization.
With this dashboard, organizations can assess their level of adherence with PCI security requirements focusing on asset management. The PCI requirements covered within this dashboard are highly focused on the goals of PCI security requirements 4, 6, 10, and 11. The goals of these requirements address asset management and awareness of impacts to systems within the cardholder data environment. The dashboard also covers additional PCI security requirements such as 2.4, 8.3, and 9.9 to provide analysts with additional PCI security requirement coverage.
Organizations can configure repositories or asset lists in order to tailor the focus of the dashboard. When the dashboard is added from the Tenable.sc Feed, the appropriate assets, IP addresses, or repositories can be specified. Assigning one of the options to the dashboard will update all filters in the components. By creating static or combination asset lists that include all systems in the Cardholder Data Environment (CDE), each component can be filtered to display results directly related to ongoing PCI security. Using an asset list filter will also allow traffic into and out of the CDE to be monitored. In order to accurately measure an organization’s PCI security posture, asset lists need to be applied as filters to provide results focused on the CDE.
This dashboard is available in the Tenable.sc Feed, a comprehensive collection of dashboards, reports, Assurance Report Cards, and assets. The dashboard can be easily located in the Tenable.sc Feed under the category Compliance & Configuration Assessments. The dashboard requirements are:
- Tenable.sc 5.3.1
- Nessus 8.5.1
- NNM 5.9.0
- LCE 6.0.0
Tenable's Tenable.sc Continuous View (CV) provides continuous network monitoring, vulnerability identification, risk reduction, and compliance monitoring. Tenable.sc is continuously updated with information about advanced threats and zero-day vulnerabilities, and new types of regulatory compliance configuration audits. Tenable Nessus Network Monitor (NNM) performs deep packet inspection to enable discovery and assessment of operating systems, network devices, hypervisors, databases, tablets, phones, web servers, cloud applications, and critical infrastructure. Tenable Log Correlation Engine (LCE) performs deep log analysis and correlation to continuously discover and track systems, applications, cloud infrastructure, trust relationships, and vulnerabilities. By integrating with Nessus, NNM, and LCE, Tenable.sc CV’s continuous network monitoring is able to detect systems and vulnerabilities across the enterprise.
This dashboard contains the following components:
- Network Mapping - Breakdown of Devices Detected on Network: This matrix presents a breakdown of detected network systems by type
- Network Mapping - New MAC Addresses in Last 30 Days: This table lists all the new MAC addresses that have never been observed before on the network, and that were first observed in the last 30 days
- Network Mapping - Hosts Not Observed in Last 7 Days: This table lists those systems that were last passively observed on the network more than seven days ago
- CSF - Top Operating Systems: The Top Operating Systems component displays a chart of the top 10 operating systems (OS) detected within a network
- Understanding Risk - Remediation Opportunities: This table displays the top remediations for the network
- CIP - Security Patch Management (CIP-007 R2): This component assists in tracking patch management, as required by CIP-007 R2. The matrix presents vulnerability summary information in several rows and columns.
- Unsupported Product Summary - Operating Systems: This indicator matrix reports on operating systems that are no longer supported
- Unsupported Product Summary - Applications: This table displays all unsupported applications by name, sorted by severity
