Surviving the #Vulnami: Operationalizing CERT-In’s 12-Hour AI Defence Blueprint

Surviving the Vulnami and operationalizing CERT-In's 12-hour defense blueprint

As artificial intelligence accelerates the discovery of vulnerabilities, organizations face an overwhelming surge in cyber risk. Learn how to adapt your defensive strategies to meet rapid mitigation mandates and transition to a continuous exposure management program.

[00:00:00] Introduction to the Vulnami and CERT-In's defense blueprint

We outline the critical turning point facing cybersecurity professionals as threat actors compress exploitation timelines.

• The Vulnami effect: Automated exploits and AI-generated code are creating a massive tsunami of vulnerabilities.
• Obsolete processes: The traditional 30-day scan and patch cycle is no longer effective for modern cyber exposure.
• Survival mechanisms: National frameworks, like CERT-In's blueprint, mandate rigorous 12-hour mitigation and response windows.

[00:06:42] The surge of vulnerabilities and the role of artificial intelligence

We explore how frontier AI models are driving an unprecedented volume of vulnerability disclosures.

• Exponential growth: Disclosures are expected to increase tenfold over the next 18 months as more organizations gain access to AI tools.
• Breaking records: The number of CVEs discovered in 2024 has already surpassed historical yearly totals, projecting up to 100,000 vulnerabilities annually.
• Strategic necessity: Scaling your security team operationally is not enough; managing this volume requires a fundamental shift in strategy.

[00:13:04] Shrinking time to exploit and shifting initial access vectors

We highlight how threat actors are weaponizing vulnerabilities faster than ever before.

• Negative timelines: The mean time to exploit has shrunk from 2.3 years in 2018 to negative 16 hours today, meaning exploits often exist before vulnerabilities are officially disclosed.
• Exploit survival curve: Over 88% of exploitable vulnerabilities are targeted within the first 24 hours of disclosure.
• Initial access shift: Vulnerability exploitation has now surpassed credential abuse as the primary initial access vector in modern cyber attacks.

[00:25:53] CERT-In's vulnerability and patch management recommendations

We break down the specific strategies advised by CERT-In to defend against AI-assisted cyber threats.

• Continuous management: Siloed, periodic vulnerability scanning is no longer sufficient; organizations must move to continuous exposure management.
• Prioritizzazione in base al rischio: Focus on exploitability and business risk rather than relying solely on CVSS severity scores.
• Comprehensive visibility: Expand your assessments beyond traditional IT infrastructure to include cloud APIs, internet-facing assets, and external attack surfaces.

[00:34:05] Meeting the aggressive 12-hour mitigation mandate

We discuss CERT-In's strict timelines for containment, mitigation, and remediation.

• 12-hour window: CISA Known Exploited Vulnerabilities found on internet-facing assets and crown jewels require immediate mitigation or patching within 12 hours.
• Internal network timelines: Known exploited vulnerabilities affecting internal systems must be patched within one day.
• High-severity flaws: All high-severity vulnerabilities require remediation within five days, highlighting the need for highly prioritized, automated workflows.

[00:44:00] Transitioning to continuous exposure management with Tenable One

We show how the Tenable One platform helps you secure your modern attack surface and meet regulatory timelines.

• Unified visibility: Consolidate your IT assets, cloud workloads, operational technology, and Active Directory environments into a single platform.
• Proactive discovery: Transition from reactive security measures to proactive, continuous discovery across your entire infrastructure.
• Seamless integration: Leverage hundreds of native integrations with incident response and patch management solutions to build automated remediation workflows.

[00:54:02] Prioritizing cyber risk with Vulnerability Priority Rating and Attack Path Analysis

We explain how Tenable translates overwhelming vulnerability counts into actionable, business-aligned tasks.

• Vulnerability Priority Rating: Reduce the noise of CVSS critical alerts by up to 98% by focusing purely on actionable, exploitable cyber threats.
• Attack Path Analysis: Map relationships between assets to identify vulnerabilities that create lateral movement paths toward your crown jewels.
• Agentic automation: Utilize Tenable One's Hexa assistant to dynamically query your cyber exposure data, tag assets, and automate ticketing workflows to accelerate your response times.

[01:01:37] Q&A: Factoring crown jewels into vulnerability prioritization

We address audience questions on combining asset criticality with threat intelligence.

• Asset Criticality Rating: Assign strict business context values to your systems to ensure your most important assets are prioritized.
• Asset exposure score: Combine your vulnerability ratings with asset criticality to create a holistic metric for evaluating true cyber exposure.
