VPM-16: Acceptable Discoverable Information
Mechanisms exist to define what information is allowed to be discoverable by adversaries and take corrective actions to remediate non-compliant Technology Assets, Applications and/or Services (TAAS).
Renumbered: Formerly VPM-06.8 in SCF 2025.4.
Control Question: Does the organization define what information is allowed to be discoverable by adversaries and take corrective actions to remediate non-compliant Technology Assets, Applications and/or Services (TAAS)?

Capability Maturity Model
Level 0 — Not Performed
Practices are non-existent, based on the inability to demonstrate an implemented and operational capability. A reasonable person would conclude the control is not being performed.
Level 1 — Performed Informally
Vulnerability & Patch Management (VPM) domain capabilities are ad hoc and inconsistent. Capability criteria associated with this control may include: ▪ Policies, standards & procedures associated with VPM domain capabilities provide limited coverage due to the depth and breadth of the existing documentation. ▪ Attack Surface Management (ASM)-related activities are decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
Level 2 — Planned & Tracked
Vulnerability & Patch Management (VPM) capabilities are requirements-driven, but are not standardized across the entity (e.g., local/regional level consistency). Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Policies and standards associated with VPM domain capabilities are formally documented and centrally-managed by the entity. ▪ Standardized Operating Procedures (SOP) associated with VPM domain capabilities are documented and maintained by process owners. ▪ IT and/or cybersecurity personnel work with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with VPM domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD). ▪ Vulnerability management-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines). ▪ Vulnerability management may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel.
Level 3 — Well Defined
Vulnerability & Patch Management (VPM) capabilities are standardized across the entity for applicability to People, Processes, Technologies, Data and/or Facilities (PPTDF) to ensure consistency for Technology Assets, Applications, Services and/or Data (TAASD). Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Policies and standards associated with VPM domain capabilities are formally documented and centrally-managed by the entity's Governance, Risk & Compliance (GRC) team, or similar function. ▪ Standardized Operating Procedures (SOP) associated with VPM domain capabilities are well-documented and kept current by process owners. ▪ A vulnerability management team, or similar function, is appropriately staffed and supported to implement and maintain VPM domain capabilities. ▪ Technology is leveraged to enhance the efficiency and accuracy of vulnerability management operations (e.g., patch management solution and vulnerability scanning solution). ▪ The entity's Governance, Risk & Compliance (GRC) team, or similar function, works with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with VPM domain capabilities to address Minimum Compliance Requirements (MCR) (e.g., applicable statutory, regulatory and/or contractual requirements) and Discretionary Security Requirements (DSR) (e.g., entity-required controls). ▪ An implemented and operational capability exists to define what information is allowed to be discoverable by adversaries and take corrective actions to remediate non-compliant Technology Assets, Applications and/or Services (TAAS).
Level 4 — Quantitatively Controlled
Utilize SCR-CMM Level 3 criteria definitions: ▪ There are no defined Level 4 criteria, since it is reasonable to assume a quantitatively-controlled process is not necessary to operationalize this control. ▪ While it may be possible to develop “metrics-driven” capabilities for this control, the criteria would be organization-specific to define.
Level 5 — Continuously Improving
Utilize SCR-CMM Level 3 or Level 4 (if available) criteria definitions: ▪ There are no defined Level 5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to operationalize this control. ▪ Level 5 capabilities should be considered “world-class” where the control builds on Level 4 capabilities, but are continuously improving through Artificial Intelligence (AI) and/or Machine Learning (ML) technologies. ▪ While it may be possible to develop responsive capabilities for this control through the use of AI and/or ML technologies, the criteria would be organization-specific to define.
Assessment Objectives
- VPM-16_A01 corrective actions to be taken if information about the system is discoverable are defined.
- VPM-16_A02 corrective actions are taken when information about the system is confirmed as discoverable.
- VPM-16_A03 information about the system is discoverable.
Technology Recommendations
Micro/Small
- Limit what information is visible about Technology Assets, Applications and/or Services (TAAS) on the internet
Small
- Minimize publicly discoverable information about Technology Assets, Applications and/or Services (TAAS) (banners, versions)
Medium
- Formal acceptable discoverable information policy
- Remove unnecessary Technology Assets, Applications and/or Services (TAAS) banners and version info
Large
