Title: Non-privileged accounts must be utilized when accessing non-administrative functions.
Vulnerability ID: V-32241
IA Controls: None
Description: This requirement is intended to limit exposure due to operating from within a privileged account or role. The inclusion of role is intended to address those situations where an access control policy, such as Role Based Access Control (RBAC), is being implemented and where a change of role provides the same degree of assurance in the change of access authorizations for both the user and all processes acting on behalf of the user as would be provided by a change between a privileged and non-privileged account.
Audit of privileged activity may require physical separation employing information systems on which the user does not have privileged access.
To limit exposure and provide forensic history of activity when operating from within a privileged account or role, the application must support organizational requirements that users of information system accounts, or roles, with access to organization defined list of security functions or security-relevant information, use non-privileged accounts, or roles, when accessing other (non-security) system functions.
If feasible, applications should provide access logging that ensures users who are granted a privileged role (or roles) have their privileged activity logged.
Use of privileged accounts for non-administrative purposes puts data at risk of unintended or unauthorized loss, modification, or exposure. In particular, DBA accounts if used for non-administration application development or application maintenance can lead to excessive privileges where privileges are inherited by object owners. It may also lead to loss or compromise of application data where the elevated privileges bypass controls designed in and provided by applications.
Check Text: Review access logs for objects owned by application owners or other non-administrative users. If any objects owned by an application owner have been accessed by DBA/administrative users, either directly or indirectly, this is a finding.
Fix Text: Require DBAs and other administrative users perform non-administrative functions using non-administrative accounts.[divider]
