The DBMS must have the capability to limit the number of failed login attempts based upon an organization-defined number of consecutive invalid attempts occurring within an organization-defined time period.
Medium Severity
<VulnDiscussion>Anytime an authentication method is exposed, to allow for the utilization of an application, there is a risk that attempts will be made to obtain unauthorized access.
To defeat these attempts, organizations define the number of times a user account may consecutively fail a login attempt. The organization also defines the period of time in which these consecutive failed attempts may occur.
By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. Limits are imposed by locking the account.
More recent brute force attacks make attempts over long periods of time to circumvent intrusion detection systems and system account lockouts based entirely on the number of failed logins that are typically reset after a successful login.
Note that user authentication and account management must be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP This requirement applies to cases where it is necessary to have accounts directly managed by Oracle.
Note also that a policy that places no limit on the length of the timeframe (for counting consecutive invalid attempts) does satisfy this requirement.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
