Object permissions granted to PUBLIC must be restricted.
An XCCDF Rule
Description
<VulnDiscussion>Permissions on objects may be granted to the user group PUBLIC. Because every database user is a member of the PUBLIC group, granting object permissions to PUBLIC gives all users in the database access to that object. In a secure environment, granting object permissions to PUBLIC must be restricted to those objects that all users are allowed to access. The policy does not require object permissions assigned to PUBLIC by the installation of Oracle Database server components be revoked.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
