Expanding Attack Surface Requires a Proactive Risk Operations Model
Written by AI from the linked story. Not reviewed by an editor. How this works
Organizations are struggling to reduce enterprise risk faster than adversaries — now supercharged by AI — can exploit newly discovered vulnerabilities. The attack surface has grown far beyond traditional IT into mobile, OT, and IoT environments, many of which lack mature security controls or visibility. Without a unified, proactive system for tracking and remediating risk across all asset types, security teams are perpetually reactive. The Risk Operations Center (ROC) concept addresses this by consolidating risk intelligence, remediation workflows, and cross-domain expertise into a single operating model. Failure to evolve beyond siloed, IT-centric security programs leaves critical gaps that adversaries are actively mapping and exploiting.
Tactical Insight
Immediate actions
- Conduct a comprehensive asset discovery exercise to inventory all IT, OT, IoT, and mobile assets and their associated risk exposure.
- Deploy automated vulnerability scanning tools that cover non-traditional assets such as industrial control systems and connected devices.
Long-term improvements
- Establish a Risk Operations Center (ROC) or equivalent function that unifies vulnerability intelligence, remediation tracking, and cross-domain risk reporting.
- Implement network segmentation to isolate OT and IoT environments from corporate IT networks, limiting lateral movement opportunities for attackers.
- Define and enforce SLA-based remediation timelines tied to asset criticality and vulnerability severity to outpace adversarial exploitation windows.
Detection measures
- Integrate continuous attack surface monitoring tools that provide real-time visibility into newly exposed assets and emerging vulnerabilities.
- Establish KPIs for mean time to remediate (MTTR) across all asset classes and report them to executive leadership to drive accountability.
