How Is Measurement Accomplished?

• Tenable Security Center Vulnerability Scanning– Used to measure systems for vulnerabilities in Operating Systems and

common applications

– Uses credentialed scans to unobtrusively log into systems to analyze patch status

• Tenable Security Center Compliance Scanning– Uses industry standard or custom audit files to measure system

configurations

– Uses credentialed scans to unobtrusively log into systems

What Are The First Steps?• Measuring systems that store or process HRCI (PII) against 10 points of

the HEISP:– Private IP addressing

– Host-based firewall

– Vulnerability Scanning and Patching program

– External logging (Splunk)

– Active, up-to-date Anti-Virus software

– Unique credentials, default passwords changed, shared accounts disabled

– Password length and complexity

– Brute force credential lock-outs

– Logging of successful and unsuccessful login attempts

21

What Are The Next Steps?

• Establish a process for ongoing compliance scanning, reporting and remediation

• Expand the service offering to comply with other regulatory standards

– HIPAA

– PCI

• Define standard build audit files to scan for deviation
