Traditional approaches, often relying solely on Common Vulnerability Scoring System (CVSS) scores, can lead to alert fatigue and inefficient resource allocation. Leading Asia-Pacific Satellite Operator recognized the need to move beyond a purely technical severity rating and adopt a risk-based vulnerability management (RBVM) approach.
The core of Leading Asia-Pacific Satellite Operator’s RBVM strategy was to prioritize vulnerabilities based on their actual risk to the business, effectively applying the 80/20 rule – focusing efforts on the 20% of vulnerabilities that posed 80% of the risk. This involved a multi-faceted assessment:
- CVSS Score: The foundational technical severity rating.
- Asset Criticality: Identifying which assets were mission-critical, held sensitive data, or were internet-facing.
- Threat Intelligence: Incorporating information on whether a vulnerability was actively being exploited in the wild or had known exploit kits available.
- Exposure: Understanding the network exposure of the vulnerable asset (e.g., directly accessible from the internet).
This intelligent prioritization allowed Leading Asia-Pacific Satellite Operator to shift from a reactive, volume-driven remediation process to a proactive, impact-driven one. Vulnerabilities affecting critical satellite communication systems or customer data platforms, especially those with active exploits, were elevated to the highest priority, ensuring immediate attention and rapid remediation. This strategic shift was instrumental in achieving significant vulnerability reduction efficiently.
Phase 3: Automation and Orchestration – Streamlining the Remediation Workflow
Manual vulnerability management processes are inherently slow, error-prone, and unsustainable at enterprise scale. Leading Asia-Pacific Satellite Operator understood that achieving an 85% reduction in six months necessitated a high degree of automation and orchestration throughout the vulnerability management lifecycle. This involved integrating their vulnerability scanning tools with their IT service management (ITSM) and workflow platforms.
Key automation initiatives included:
- Automated Ticket Creation: When a new vulnerability was identified by scanning tools (e.g., leading vulnerability scanning tools), an automated ticket was created in their IT Service Management (ITSM) platforms instance. This ensured that no vulnerability fell through the cracks and that remediation tasks were immediately assigned to the relevant teams.
- Workflow-Driven Remediation: The ITSM platform was configured with predefined workflows for different types and severities of vulnerabilities. This guided remediation teams through the necessary steps, from investigation and solution identification to implementation and verification.
- Automated Patch Management: For non-critical systems and routine updates, Leading Asia-Pacific Satellite Operator implemented automated patch management solutions. This significantly reduced the manual effort required for patching, allowing teams to focus on more complex or critical vulnerabilities.
