Consecutive Invalid Logon Attempts, v1.0

Defines conformance and assessment criteria for compliance with minimum security requirements for consecutive invalid logon attempts as related to overall access control requirements.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Assessment Step

1
Consecutive Invalid Logon Attempts (ConsecutiveInvalidLogonAttempts)
Does the information system enforces a limit of <organization-defined number> consecutive invalid logon attempts by a user during a <organization-defined time period>?
Artifacts
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
A2
Provide the maximum number of permitted invalid login attempts. Enter 0 if there is no limit.
Parameters
Maximum Attemptsrequired
NUMBER : Provide the maximum number of unsuccessful login attempts enforced by the system.
Time Periodrequired
NUMBER : Provide the time window (in minutes) the system uses to track unsuccessful login attempts.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; <organization-defined frequency>]), the option(s) implemented by the organization must also be defined and documented.

Conformance Criteria (1)

C1
The information system must enforce a limit of <organization-defined number> consecutive invalid logon attempts by a user during a <organization-defined time period>.
