Procedure¶

Step 1: Monitoring Infrastructure Setup¶

Objective: Establish monitoring capabilities for vendor portfolio

Monitoring Data Sources: | Source | Data Type | Frequency | Cost Model | |--------|-----------|-----------|------------| | Security Ratings (BitSight, SecurityScorecard) | Security posture | Daily | Per vendor | | Threat Intelligence | Breach/incident news | Continuous | Subscription | | Financial Services (D&B, Experian) | Financial health | Monthly | Per vendor | | Regulatory Databases | Compliance actions | Weekly | Variable | | Dark Web Monitoring | Credential exposure | Continuous | Subscription | | Certificate Transparency | SSL/domain changes | Daily | Free/included |

Tier-Based Monitoring: | Tier | Security Ratings | Threat Intel | Financial | Regulatory | |------|-----------------|--------------|-----------|------------| | 1 | Daily alerts | Continuous | Monthly | Weekly | | 2 | Weekly review | Daily digest | Quarterly | Monthly | | 3 | Monthly review | Weekly digest | Annual | Quarterly | | 4 | Quarterly | N/A | N/A | Annual |

Alert Thresholds: | Signal | Critical | High | Medium | |--------|----------|------|--------| | Security score drop | >15 points | 10-15 points | 5-10 points | | Breach notification | Any confirmed | Suspected | Industry | | Financial rating drop | 2+ grades | 1 grade | Watch list | | Regulatory action | Fine/sanction | Investigation | Warning |

Duration: 4-8 hours (initial setup)

Step 2: Security Posture Monitoring¶

Objective: Track vendor security ratings and identified vulnerabilities

Daily Monitoring Activities: - [ ] Review security rating alerts - [ ] Check for new critical findings - [ ] Monitor for score drops - [ ] Review exposed assets - [ ] Check botnet/malware indicators

Security Rating Components: | Factor | Weight | Monitoring Focus | |--------|--------|-----------------| | Network security | High | Open ports, vulnerabilities | | Patching cadence | High | CVE remediation time | | Endpoint security | Medium | Malware infections | | IP reputation | Medium | Botnet participation | | Application security | Medium | Web app vulnerabilities | | DNS health | Low | Configuration issues |

Score Change Response: | Change | Action | Timeline | |--------|--------|----------| | Critical drop (>15) | Immediate vendor contact | 24 hours | | Significant drop (10-15) | Review and vendor notification | 48 hours | | Moderate drop (5-10) | Add to watch list, next review | 1 week | | Minor fluctuation (<5) | Document, monitor | Standard cycle |

Duration: 30-60 minutes daily

Step 3: Breach and Incident Monitoring¶

Objective: Detect and respond to vendor security incidents

Monitoring Sources: - [ ] Threat intelligence feeds - [ ] Security news aggregation - [ ] Vendor security notifications - [ ] Regulatory breach databases - [ ] Dark web monitoring - [ ] Social media monitoring

Incident Classification: | Incident Type | Relevance Check | Response | |---------------|-----------------|----------| | Confirmed breach | Data we share affected? | Immediate | | Ransomware attack | Service disruption? | High priority | | Vulnerability disclosure | Systems we integrate with? | Assess impact | | Third-party breach | Subcontractor we use? | Investigate | | Industry breach | Similar service/data? | Lessons learned |

Incident Response Workflow: 1. Incident detected 2. Verify incident details 3. Assess impact to organization 4. Contact vendor for information 5. Document vendor response 6. Determine if action required 7. Update risk assessment if needed 8. Report to stakeholders

Vendor Incident Questions: - [ ] What data/systems were affected? - [ ] Is our data/access impacted? - [ ] What is the root cause? - [ ] What remediation is underway? - [ ] What is the timeline for resolution? - [ ] What notification will be provided?

Duration: Variable (1-4 hours per incident)

Step 4: Compliance Status Tracking¶

Objective: Monitor vendor compliance certifications and attestations

Certification Tracking: | Certification | Renewal Period | Lead Time Alert | |---------------|---------------|-----------------| | SOC 2 Type II | Annual | 60 days | | ISO 27001 | 3 years (annual surveillance) | 90 days | | PCI DSS | Annual | 60 days | | HIPAA attestation | Annual | 60 days | | FedRAMP | Annual | 90 days | | Cyber insurance | Annual | 30 days |

Monitoring Activities: - [ ] Track certification expiration dates - [ ] Request updated reports before expiration - [ ] Monitor for regulatory actions - [ ] Track compliance findings/exceptions - [ ] Verify subcontractor compliance

Compliance Change Response: | Change | Impact | Action | |--------|--------|--------| | Certification lapsed | High | Suspend if critical | | Qualified opinion | Medium | Review findings | | New finding | Variable | Assess remediation | | Scope reduction | Variable | Assess coverage | | Regulatory action | High | Immediate review |

Duration: 2-4 hours weekly

Step 5: Financial and Operational Monitoring¶

Objective: Detect financial and operational risks affecting vendor viability

Financial Indicators: | Indicator | Source | Alert Threshold | |-----------|--------|-----------------| | Credit rating | D&B, Experian | 2+ grade drop | | Payment behavior | Trade reports | >60 days delinquent | | Litigation | Court records | Material lawsuits | | Ownership change | News/SEC | Any M&A activity | | Layoffs | News | >10% workforce |

Operational Indicators: | Indicator | Source | Alert Threshold | |-----------|--------|-----------------| | Service outages | Status pages, news | Extended downtime | | Key personnel changes | LinkedIn, news | C-suite departures | | Product discontinuation | Vendor communication | Affects our use case | | Support quality | Internal feedback | Degrading response |

Viability Risk Response: | Risk Level | Indicators | Action | |------------|-----------|--------| | Critical | Bankruptcy filing, major breach | Activate exit plan | | High | Significant financial decline | Develop contingency | | Medium | Personnel/operational issues | Increased monitoring | | Low | Minor fluctuations | Standard monitoring |

Duration: 2-4 hours monthly

Step 6: Reporting and Escalation¶

Objective: Communicate monitoring findings to stakeholders

Regular Reporting: | Report | Frequency | Audience | Content | |--------|-----------|----------|---------| | Monitoring Dashboard | Continuous | VRM Team | All alerts, scores | | Weekly Summary | Weekly | Security Team | Notable changes | | Monthly Report | Monthly | Risk Committee | Portfolio health | | Quarterly Review | Quarterly | Executive | Trends, issues |

Report Metrics: - [ ] Vendors monitored by tier - [ ] Average security scores by tier - [ ] Score changes (improved/declined) - [ ] Active alerts and issues - [ ] Certifications expiring - [ ] Incidents detected - [ ] Remediation status

Escalation Triggers: | Event | Escalation Path | Timeline | |-------|-----------------|----------| | Confirmed breach (Tier 1) | CISO, Legal | Immediate | | Critical score drop | VRM Lead, Business Owner | 24 hours | | Certification lapse (Tier 1) | Business Owner, VRM Lead | 24 hours | | Financial distress | CFO, Business Owner | 48 hours | | Regulatory action | Legal, Compliance | 24 hours |
