These forgotten assets often go unpatched and unmonitored, making them prime targets for attackers who routinely scan the internet for exposed, vulnerable services. Novee's External Surface Testing tool highlights a critical gap: if your security team doesn't know an asset exists, it will never be included in vulnerability management cycles. This matters because attackers don't need an invitation — newly disclosed CVEs are weaponized within hours, and unknown assets are unlikely to receive emergency patches. Continuous external attack surface management combined with automated penetration testing is now essential to close this visibility gap.","**Immediate actions:**\n- Conduct an emergency external asset discovery scan to identify all internet-facing systems, including legacy and forgotten infrastructure.\n- Cross-reference discovered assets against your CMDB or asset inventory and flag any unregistered or unexpected exposures for immediate remediation.\n\n**Long-term improvements:**\n- Implement a continuous External Attack Surface Management (EASM) program that automatically discovers and inventories internet-facing assets on an ongoing basis.\n- Establish a formal asset lifecycle policy requiring that all internet-facing assets be registered, reviewed quarterly, and decommissioned through an approved process.\n- Integrate newly disclosed CVE feeds into your vulnerability management tooling so that internet-exposed assets are automatically tested against emerging threats within 24–48 hours of disclosure.\n\n**Detection measures:**\n- Schedule regular automated penetration tests against your external attack surface, prioritizing assets that have not been tested in the past 90 days.\n- Configure alerting for any new internet-facing services or ports that appear in external scans without a corresponding change-management record.",[12,13,14,15,16,17,18],"CIS Control 1: Inventory and Control of Enterprise Assets","CIS Control 7: Continuous Vulnerability Management","NIST SP 800-53 SI-2: Flaw Remediation","ISO\u002FIEC 27001:2022 A.8.8: Management of technical vulnerabilities","OWASP A06:2021 Vulnerable and Outdated Components","NIS2 Article 21(2)(b)","NIST CSF 2.0 PR.AA: Identity Management, Authentication, and Access Control",{"NIS2 Article 21(2)(b)":20,"NIST SP 800-53 SI-2: Flaw Remediation":21,"OWASP A06:2021 Vulnerable and Outdated Components":22,"CIS Control 7: Continuous Vulnerability Management":23,"CIS Control 1: Inventory and Control of Enterprise Assets":24,"ISO\u002FIEC 27001:2022 A.8.8: Management of technical vulnerabilities":25,"NIST CSF 2.0 PR.AA: Identity Management, Authentication, and Access Control":26},"NIS2 requires entities to implement measures for incident handling and risk management including asset visibility; unmanaged external assets undermine the baseline security posture NIS2 mandates for operators of essential services.","SI-2 requires organizations to identify, report, and correct information system flaws — a process that only works if all internet-facing assets are known and included in the remediation workflow.","Forgotten internet-facing assets are disproportionately likely to run outdated, unpatched components that match this risk category, making them easy targets for automated exploitation of known CVEs.","Unknown assets are excluded from vulnerability scanning cycles, meaning newly disclosed CVEs go undetected on them; CIS Control 7 requires continuous scanning of all in-scope assets including those on the external perimeter.","Forgotten internet-facing assets persist precisely because no authoritative inventory exists; CIS Control 1 mandates continuous discovery and tracking of all assets to eliminate unknown exposures.","This control explicitly requires organizations to obtain timely information about technical vulnerabilities in all assets they operate and to take appropriate measures, which presupposes a complete and current asset inventory.","Forgotten external assets often lack proper access controls and authentication hardening; the Protect function of the CSF requires that all managed assets have appropriate protective measures applied, which is impossible without full asset visibility.","published","2026-11-03T15:21:42.454703+00:00","2026-11-03T15:21:42.422+00:00",{"id":7,"url":31,"slug":32,"title":33},"https:\u002F\u002Fwww.helpnetsecurity.com\u002F2026\u002F11\u002F03\u002Fnovee-external-surface-testing\u002F","novee-puts-forgotten-internet-facing-assets-through-penetration-testing-317162","Novee puts forgotten internet-facing assets through penetration testing",[35,41],{"id":36,"name":37,"slug":38,"description":39,"color":40},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":42,"name":43,"slug":44,"description":45,"color":46},"859cf0ad-a7e9-42bb-a75d-bac6511fa5d5","Configuration Management","configuration-management","Misconfigs, default credentials, exposed services","#eab308",[],[49,52,56],{"slug":38,"name":50,"problem":51},"Vulnerability scanning and prioritisation","You know which systems are vulnerable, and which ones to fix first.",{"slug":53,"name":54,"problem":55},"attack-surface-management","External attack surface management (EASM)","You find your forgotten internet-facing systems before attackers do.",{"slug":57,"name":58,"problem":59},"penetration-testing","Penetration testing and bug bounty","Someone friendly finds the holes before someone hostile does."]
