1 Approaches to meeting the PCI Vulnerability Management and Penetration Testing Requirements Clay Keller
2 Full PCI Glossary at following url. PCI : Acronym for “Payment Card Industry.”DSS : Data Security Standards. There are 12 groups of standards.PCI-SSC : Payment Card Industry Security Standards CouncilASV : Approved Scanning VendorFull PCI Glossary at following url.https://www.pcisecuritystandards.org/documents/pci_glossary_v20.pdf
3 Goals of Presentation High Level overview of the PCI Requirements for Vulnerability ScanningPenetration TestingHow to meet those requirements.
4 Disclaimer!Always review your PCI compliance efforts with a QSA if possible and ensure you are using the most current documentation.I am not a QSA!
5 PCI-DSS Vulnerability Management Which Sections in the DSS?6.6 – Public Facing App Review11.2 – Vulnerability Scanning11.3 – Penetration Testing(11.1 Will not be covered today – Rogue Wireless Detection)
6 PCI-DSS 6.66.6 For public-facing web applications, ... ensure these applications are protected against known attacks by either of the following methods:Reviewing public-facing web applications via manual or automated application vulnerability security assessment tools or methods, at least annually and after any changesInstalling a web-application firewall in front of public-facing web applications
7 Meeting the 6.6 Requirements Focused on “Public Facing” Web Applications.Annually & After Changes.Reviewers must specialize in App securityReviewers must have Independence.Need to validate fixes!How ??Manual application testing.WebScarab, Etc..Automated Testing ToolsWebinspect. Etc..Phoenix/Tools
8 Meeting the 6.6 Requirements Contract with a 3rd Party Provider to perform testing.Setup your own testing capability.Some Vulnerability Scanners are starting to build in Application ScanningBuild in Security testing to your Q/A and pre-release testing.
9 Meeting the 6.6 Requirements Implement a Web Application Firewall (WAF)A web application firewall (WAF) is an appliance, server plugin, or filter that applies a set of rules to an HTTP conversation. Generally, these rules cover common attacks such as Cross-site Scripting (XSS) and SQL Injection.OWASP website has great information on WAF's.
10 PCI-DSS 11.211.2 Run internal and external network vulnerability scans at least quarterly and after any significant change in the network
11 Meeting 11.2 RequirementsInternal AND External Scans of your PCI Scope Networks.Must be done at least Quarterly.External Scans Must use an “ASV” to attest or approve your scan results.Must show that “changes” are being scanned.Many Vulnerability Scanning tools exist.Many ASV's exist.
12 Meeting 11.2 Requirements Internal External You Can Do This! Quarterly (at least)After ChangesExternalUse an ASV.Must run from the Internet.Must be whitelisted in IPS/IDS.
13 PCI-DSS 11.311.3 Perform penetration testing at least once a year and after any significant infrastructure or application upgrade or modification (such as an operating system upgrade, a sub-network added to the environment, or a web server added to the environment). These penetration tests must include the following:Network-layer penetration testsApplication-layer penetration tests
15 Meeting 11.3 Requirements Does not need to be an ASV. Create a “Register” or Inventory of Applications and Network devices to test to ensure complete coverage.Review testing plan with a QSA if possible.Testing Can be expensive.The PCI SSC Website has a guidance document.
16 Summary of PCI Vulnerability Management Tasks Internal Quarterly Scans.External Quarterly Scans.Internal Annual Penetration TestsExternal Annual Penetration TestsExternal Annual Web App TestingInternal Annual Application Testing.After Changes ??Need to implement process to ensure new additions to your environment are tested adequately before implementation.Strong Security Governance reduces rework!
17 Final Recommendations Have a clearly defined “Cardholder Environment.”Have QSA review your Vulnerability Management Processes.Be able to explain your methodology clearly.Ensure you are meeting the DSS standards.Security is the goal. Compliance is a minimum!
