SCR-CMM
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
Physical & Environmental Security (PES) domain capabilities are ad hoc and inconsistent. Capability criteria associated with this control may include:
▪ Policies, standards & procedures associated with PES domain capabilities provide limited coverage due to the depth and breadth of the existing documentation.
▪ Physical security-related activities are decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
▪ Physical security controls are primarily administrative in nature (e.g., policies & standards), focusing on protecting High Value Assets (HVAs).
▪ IT and/or cybersecurity personnel implement appropriate physical security practices to protect the confidentiality, integrity, availability and safety of the organization's technology assets and data.
Level 2 Planned Tracked
Physical & Environmental Security (PES) 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 PES domain capabilities are formally documented and centrally-managed by the entity.
▪ Standardized Operating Procedures (SOP) associated with PES 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 PES domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD).
▪ Physical security / facilities management-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines).
▪ Physical security / facilities management may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel.
▪ Physical security controls and technologies primarily focus on protecting High Value Assets (HVAs), including environments where sensitive/regulated data is stored, transmitted and processed.
▪ Where applicable, physical security controls and technologies are configured to generate a log entry for each access attempt through controlled ingress and egress points.
Level 3 Well Defined
Physical & Environmental Security (PES) 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 PES 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 PES domain capabilities are well-documented and kept current by process owners.
▪ A facilities management team, or similar function, is appropriately staffed and supported to implement and maintain NET domain capabilities.
▪ Technology is leveraged to enhance the efficiency and accuracy of physical and environmental security operations (e.g., facility management solution, visitor log management automation and proximity badge access).
▪ 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 PES 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 physical security capability exists to enforce physical access to critical systems or sensitive/regulated data, in addition to the physical access controls for the facility.
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.

Artikel 21
Som led i deres kontrol med rettigheder vedrørende adgangsforvaltning udvikler, dokumenterer og gennemfører finansielle enheder en politik, der indeholder alt følgende:
a)
tildeling af adgangsrettigheder til IKT-aktiver på grundlag af need to know-princippet, need to use-princippet og least privilege-princippet, herunder fjernadgang og adgang i hastetilfælde
b)
adskillelse af opgaver, der er udformet med henblik på at forhindre uberettiget adgang til kritiske data eller forhindre tildeling af kombinationer af adgangsrettigheder, der kan anvendes til at omgå kontroller
c)
en bestemmelse om brugeransvar, idet brugen af generiske og delte brugerkonti begrænses så vidt muligt og det sikres, at brugerne til enhver tid kan identificeres med hensyn til de handlinger, der udføres i IKT-systemerne
d)
en bestemmelse om begrænsning af adgangen til IKT-aktiver, der fastsætter kontrolforanstaltninger og værktøjer, som skal forhindre uautoriseret adgang
e)
procedurer for kontoforvaltning med henblik på tildeling, ændring eller tilbagekaldelse af adgangsrettigheder for brugerkonti og generiske konti, herunder generiske administratorkonti, som omfatter bestemmelser om alt følgende:
i)
tildeling af roller og ansvarsområder for tildeling, gennemgang og tilbagekaldelse af adgangsrettigheder
ii)
tildeling af privilegeret adgang, hasteadgang og administratoradgang på need to know-basis eller ad hoc-basis for alle IKT-systemer
iii)
øjeblikkelig inddragelse af adgangsretten ved ansættelsesforholdets ophør, eller når adgangen ikke længere er nødvendig
iv)
ajourføring af adgangsrettigheder, når ændringer er nødvendige, og mindst en gang om året for alle IKT-systemer, bortset fra IKT-systemer, der understøtter kritiske eller vigtige funktioner, og mindst hver sjette måned for IKT-systemer, der understøtter kritiske eller vigtige funktioner.
f)
autentificeringsmetoder, herunder alle følgende:
i)
anvendelse af autentificeringsmetoder, der svarer til den klassificering, der er fastsat i overensstemmelse med artikel 8, stk. 1, i forordning (EU) 2022/2554, og til IKT-aktivernes overordnede risikoprofil og under hensyntagen til førende praksis
ii)
anvendelse af stærke autentificeringsmetoder i overensstemmelse med førende praksis og teknikker vedrørende fjernadgang til den finansielle enheds netværk, privilegeret adgang, adgang til IKT-aktiver, der understøtter kritiske eller vigtige funktioner, eller IKT-aktiver, der er offentligt tilgængelige
g)
foranstaltninger til fysisk adgangskontrol, herunder:
