  • Evidence that all vulnerabilities found were ranked, corrected and the application re-evaluated after correction
  • Inventory of public-facing web applications, reconciled so none are outside the process
  • Independence evidence for the assessing party
Where this commonly fails
  • Annual assessment performed while the after each change trigger is ignored, which is where most exposure appears
  • Findings corrected without re-evaluation, so the fix is unverified
  • Application inventory incomplete, missing marketing sites and APIs that reach the same environment

  • Evidence it is actively running and up to date, with the version or ruleset in use
  • Audit logs generated by the solution, and evidence they are retained and reviewed
  • Coverage evidence reconciling protected applications against the public-facing application inventory
Where this commonly fails
  • Solution deployed in detection mode indefinitely because blocking risks false positives, so it never prevents
  • Applications reachable by a path that bypasses the solution, such as a direct origin address
  • Rulesets left at deployment defaults with no update process, so new attack classes are unaddressed

  • Review record showing the access control procedures are kept up to date
  • Evidence of use, such as access request records that follow the documented procedure
  • Distribution evidence to system owners, managers who approve access and administrators who provision it
Where this commonly fails
  • Procedures describe the joiner process while movers and leavers, where access accumulates, are thin
  • Documented for the primary application with cloud consoles, databases and administrative tooling uncovered
  • Approvers unaware of the procedure, so approvals are given without applying need to know
7.1.2
Roles and responsibilities for performing activities in Requirement 7 are documented, assigned, and understood

Roles and responsibilities for performing activities in Requirement 7 are documented, assigned, and understood

Artefacts an auditor will ask for

  • Assignment records naming who holds each role
  • Interview confirmation that assigned personnel understand their day to day access control responsibilities
  • Evidence that authority to approve privileged access is explicitly assigned and bounded
Where this commonly fails
  • Approval authority assumed by line managers with no documented assignment or limit
  • Ownership of the access control model itself unassigned, so it ages without review
  • Administrators provision access on request with nobody accountable for whether need to know was applied
7.2.1
An access control model is defined and includes granting access as follows: • Appropriate access depending on the entity's business and access needs. • Access to system components and data resources that is based

An access control model is defined and includes granting access as follows: • Appropriate access depending on the entity's business and access needs. • Access to system components and data resources that is based

Artefacts an auditor will ask for
  • The documented access control model showing access granted by business and access needs
  • Evidence access is based on job classification and function, with the role to entitlement mapping
  • Documentation of the least privileges required for each job classification
  • Access control model settings examined against the documented model to confirm they agree
  • Approval record for the model itself by authorised personnel
Where this commonly fails
  • Model documented in policy while entitlements in the system were built up historically and do not match it
  • Job classifications defined so broadly that least privilege has no meaning
  • Privileged and service accounts excluded from the model entirely
7.2.2
Access is assigned to users, including privileged users, based on: • Job classification and function. • Least privileges necessary to perform job responsibilities

  • Comparison of assigned access against the job classification for a sample of users, showing least privilege applied
  • Management confirmation that the access held by their staff is what the role requires
  • Records showing access reduced when a user changed role
Where this commonly fails
  • Access cloned from an existing user at onboarding, which propagates accumulated privilege
  • Privileged users assigned broad administrative rights because scoping them is harder than granting them
  • Role changes add new access without removing the old, so entitlement only ever grows
7.2.3
Required privileges are approved by authorized personnel

Required privileges are approved by authorized personnel

Artefacts an auditor will ask for
  • Policies and procedures defining the approval process for privileges and who is authorised to approve
  • Documented approvals for a sample of user IDs, matched against the privileges actually assigned
  • Evidence that the approval specifies the privileges granted, so assignment can be checked against it

Where this commonly fails
  • Approvals held as email threads that do not state which privileges were approved
  • Privileges assigned first and approved retrospectively, or never
  • Approver is the same person as the requester for administrative accounts
7.2.5.1

The access control system(s) is configured to enforce permissions assigned to individuals, applications, and systems based on job classification and function

The access control system(s) is configured to enforce permissions assigned to individuals, applications, and systems based on job classification and function

Artefacts an auditor will ask for
  • Vendor documentation and system settings for the access control system showing enforcement of permissions by job classification and function
  • Evidence permissions apply to individuals, applications and systems, covering non-human identities
  • Configuration showing individual rights are inherited from group membership rather than granted directly
  • Sample extracts of effective permissions demonstrating what the system actually enforces
  • Reconciliation between the enforced permissions and the documented access control model
Where this commonly fails
  • Direct individual grants layered on top of group membership, so effective access differs from the model
  • Application and system accounts assigned permissions outside the access control system
  • Enforcement verified from the configuration screen rather than from effective permission output
7.3.3
The access control system(s) is set to “deny all” by default

The access control system(s) is set to “deny all” by default

Artefacts an auditor will ask for
  • Vendor documentation and system settings showing the access control system is set to deny all by default
  • Configuration evidence for each in scope access control system, not only the primary one
  • Test evidence that an identity with no assigned permission is refused
  • Evidence that default or built-in permissive entries have been removed or restricted
  • Change control preventing the default from being relaxed
Where this commonly fails
  • Default deny at the application while the database or file share underneath grants broad read
  • Built-in groups such as everyone or authenticated users left with permissions, defeating the default
  • Deny all asserted from product documentation with no test on the actual deployment
7.2.4
All user accounts and related access privileges, including third-party/vendor accounts, are reviewed as follows: • At least once every six months. • To ensure user accounts and access remain appropriate based on job function.

Artefacts an auditor will ask for
  • Evidence that every user is assigned a unique ID before access to system components or cardholder data is allowed
  • User account lists from in scope components showing no shared or generic IDs outside approved exceptions
  • Audit logs demonstrating actions can be traced back to an individual user
  • Provisioning records showing ID assignment precedes access being granted
  • Reconciliation of accounts against the current personnel list to identify orphans
Where this commonly fails
  • Unique IDs at the application while the database, operating system or appliance is accessed through a shared administrative account
  • Contractors and third party support using a shared vendor account, so their actions are unattributable
  • Service accounts used interactively by named people, breaking attribution
8.2.2
Group, shared, or generic IDs, or other shared authentication credentials are only used when necessary on an exception basis, and are managed as follows: • ID use is prevented unless needed for an exceptional

Group, shared, or generic IDs, or other shared authentication credentials are only used when necessary on an exception basis, and are managed as follows: • ID use is prevented unless needed for an exceptional

Artefacts an auditor will ask for
  • User account lists and documentation identifying every group, shared or generic ID and other shared authentication credential in use
  • The exceptional circumstance justifying each, with management approval
  • Evidence use is prevented unless needed and limited to the time needed for that circumstance
  • Records showing individual user identity is confirmed before use of a shared ID, and the actions taken are attributable
  • Evidence shared credentials are changed when someone with knowledge of them leaves
Where this commonly fails
  • Shared administrative accounts used routinely rather than on an exception basis, with the exception rationale written once
  • Credential not changed after a holder departs, so the account remains usable by them
  • Use of the shared ID not linked back to an individual, so no attribution exists for the period of use
8.2.3
Additional requirement for service providers only: Service providers with remote access to customer premises use unique authentication factors for each customer premises

Additional requirement for service providers only: Service providers with remote access to customer premises use unique authentication factors for each customer premises

Artefacts an auditor will ask for
  • Authentication policies and procedures for service provider remote access to customer premises
  • Evidence a unique authentication factor is used for each customer premises, such as per customer credentials or certificates
  • Inventory of customer environments accessed remotely and the distinct factor used for each
  • Interview confirmation from support personnel about how they authenticate to each customer
  • Records showing a factor compromised for one customer cannot be used at another
Where this commonly fails
  • One support tool account reused across the customer base, so a single compromise reaches every customer
  • Unique accounts created per customer but sharing one password across them
  • Per customer factors issued at onboarding and never rotated as support staff change
8.2.4
Addition, deletion, and modification of user IDs, authentication factors, and other identifier objects are managed as follows: • Authorized with the appropriate approval. • Implemented with only the privileges specified on the documented approval

Addition, deletion, and modification of user IDs, authentication factors, and other identifier objects are managed as follows: • Authorized with the appropriate approval. • Implemented with only the privileges specified on the documented approval

Artefacts an auditor will ask for
  • Documented authorisations covering additions, modifications and deletions of user IDs, authentication factors and identifier objects
  • System settings and account records showing the privileges implemented match those on the documented approval
  • Evidence lifecycle events are logged, so an unauthorised change would be visible
  • A sample walk through comparing an approval to the resulting account state
  • Records showing a modification request was refused or altered before implementation
Where this commonly fails
  • Approval covers the addition while later modifications proceed on informal request
  • Implemented privileges exceed the documented approval, and nothing compares the two
  • Deletions performed without record, so it cannot be shown when access ended
8.2.5
Access for terminated users is immediately revoked

Access for terminated users is immediately revoked

Artefacts an auditor will ask for
  • Termination information source, such as the human resources leaver feed, and evidence it reaches the access administration process
  • Current user access lists for both local and remote access, checked against recent terminations
  • Evidence terminated user IDs are deactivated or removed immediately rather than at the next review
  • Records of physical authentication factors returned or disabled, such as tokens and cards
  • Timing evidence showing the interval between termination and revocation
Where this commonly fails
  • Revocation covers the directory while local accounts on servers, appliances and applications remain active
  • Contractors and third party staff not on the leaver feed, so their access survives the engagement
  • Revocation batched to a weekly job, which does not meet the immediate requirement
8.2.6
Inactive user accounts are removed or disabled within 90 days of inactivity

Inactive user accounts are removed or disabled within 90 days of inactivity

Artefacts an auditor will ask for
  • User account listing with last logon information for all in scope system components
  • Evidence accounts inactive for 90 days are removed or disabled, with the mechanism that enforces it
  • The automated or scheduled process performing the check, and its execution records
  • Handling of accounts where last logon is not recorded, so inactivity can still be determined
  • Exception records where an account is retained despite inactivity, with justification
Where this commonly fails
  • Last logon not collected for some platforms, so inactivity cannot be measured and those accounts are skipped
  • Service and application accounts exempted as a class rather than individually justified
  • Check performed manually and missed during busy periods, so the 90 day limit slips
8.2.7
Third-party access managed

Accounts used by third parties to access, support, or maintain system components via remote access are managed and monitored.

Artefacts an auditor will ask for
  • Inventory of third-party accounts and vendors
  • Procedure to enable only when needed and disable after use
  • Session monitoring logs and recordings
  • Approval tickets for each session
  • Quarterly review of third-party access

Artefacts an auditor will ask for
  • Documentation describing the authentication factors used for user and administrator access to system components
  • For each type of authentication factor, observation or configuration evidence that access is authenticated using it
  • Inventory of in scope system components and the authentication method for each
  • Evidence no access path permits access without authentication
  • Records for non-console and console access alike
Where this commonly fails
  • Authentication enforced on the main path while a management interface, API or legacy port allows unauthenticated access
  • Certificates or keys used as the factor with no control over their distribution, weakening the something you have claim
  • Component inventory incomplete, so a component authenticating differently is never assessed
8.3.10

Artefacts an auditor will ask for
  • Customer-facing guidance documents
  • Customer portal notices and FAQs
  • Sample communications to customers

Artefacts an auditor will ask for
  • Vendor documentation and system configuration showing authentication factors are rendered unreadable with strong cryptography in transmission and in storage
  • Examination of authentication factor repositories confirming stored values are not readable
  • Evidence the hashing or encryption method meets a strong cryptography definition, including the algorithm and parameters
  • Capture or configuration evidence that authentication factors are not sent in the clear on any path
  • Key or salt management evidence for the stored factors
Where this commonly fails
  • Application credentials protected while an underlying directory, database or legacy store keeps reversible or weakly hashed values
  • Transmission protected to the front end and forwarded internally in the clear
  • Legacy hash algorithms retained for old accounts because rehashing requires a reset
8.3.3
User identity is verified before modifying any authentication factor

User identity is verified before modifying any authentication factor

Artefacts an auditor will ask for
  • Procedures for modifying authentication factors, including the identity verification steps required
  • Observation of security or service desk personnel performing a modification request, showing verification before the change
  • The verification methods permitted and their strength, such as knowledge questions, callback or a second channel
  • Records of modification requests showing the verification performed
  • Evidence of a request refused because identity could not be verified
Where this commonly fails
  • Verification uses information an attacker can obtain, such as employee number or manager name
  • Self service reset relies on a channel the attacker may already control, such as the same mailbox
  • Procedure documented but not followed under pressure, with no monitoring that would show it
8.3.4
Invalid authentication attempts are limited by: • Locking out the user ID after not more than 10 attempts. • Setting the lockout duration to a minimum of 30 minutes or until the user's identity

Invalid authentication attempts are limited by: • Locking out the user ID after not more than 10 attempts. • Setting the lockout duration to a minimum of 30 minutes or until the user's identity

Artefacts an auditor will ask for
  • System configuration settings showing lockout after not more than 10 invalid authentication attempts
  • System configuration showing lockout duration of at least 30 minutes, or lockout until identity is confirmed
  • Evidence the settings apply across all in scope components, including those with their own local authentication
  • Test or log evidence showing lockout actually occurs
  • The process for confirming identity where lockout is released by an administrator
Where this commonly fails
  • Lockout configured in the directory while applications with local authentication have no limit
  • Threshold or duration relaxed for administrative accounts to avoid operational disruption
  • Lockout applied per component, so an attacker spreading attempts across systems never trips it
8.3.5
If passwords/passphrases are used as authentication factors to meet Requirement 8.3.1, they are set and reset for each user as follows: • Set to a unique value for first-time use and upon reset. •

If passwords/passphrases are used as authentication factors to meet Requirement 8.3.1, they are set and reset for each user as follows: • Set to a unique value for first-time use and upon reset. •

Artefacts an auditor will ask for
  • Procedures for setting and resetting passwords or passphrases
  • Evidence each initial and reset value is set to a unique value rather than a standard or predictable one
  • Configuration forcing a change immediately after first use
  • Observation of security personnel performing a reset, showing both elements applied
  • Records or configuration showing the delivery method for the initial value
Where this commonly fails
  • A standard welcome password used for all new accounts, which fails the unique value element
  • Forced change on first use not enforced technically, so the initial value can persist
  • Initial value delivered in the same message as the user ID over an unprotected channel
8.3.6
If passwords/passphrases are used as authentication factors to meet Requirement 8.3.1, they meet the following minimum level of complexity: • A minimum length of 12 characters (or IF the system does not support 12

If passwords/passphrases are used as authentication factors to meet Requirement 8.3.1, they meet the following minimum level of complexity: • A minimum length of 12 characters (or IF the system does not support 12

Artefacts an auditor will ask for
  • System configuration settings showing minimum length of 12 characters, or eight where the system cannot support 12
  • System configuration showing both numeric and alphabetic characters are required
  • Evidence the parameters are enforced on every system where passwords are used as the authentication factor
  • Documentation of any system limited to eight characters and the reason it cannot support 12
  • Test evidence that a non-conforming password is rejected
Where this commonly fails
  • Complexity enforced at the directory while applications with local password stores accept weaker values
  • The eight character allowance applied by default rather than only where the system genuinely cannot support 12
  • Existing passwords never brought up to the standard because the policy applies only at next change
8.3.7
Password history
