Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events. Suppression of auditing could permit an adversary to evad

Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information. Therefore, it must be possible to configure auditing to do this. DBMSs typically make such information available through views or functions.

Within the database, object ownership implies full privileges to the owned object, including the privilege to assign access to the owned objects to other subjects.

Use of weak or not validated cryptographic algorithms undermines the purposes of utilizing encryption and digital signatures to protect data. Weak algorithms can be easily broken and not validated cryptographic modules may not implement algorithms correct

Any DBMS or associated application providing too much information in error messages on the screen or printout risks compromising the data and security of the system. The structure and content of error messages need to be carefully considered by the organi

Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escalated or administrative privileges) provide the regular use
