| V-2587 | High | Oracle accounts should not have permission to view the table SYS.LINK$ which contain unencrypted database link passwords. | The SYS.LINK$ table contains unencrypted passwords to enable transparent connections to remote databases. In addition, remote database connections themselves can provide information to... |
| V-3810 | Medium | DBMS authentication should require use of a DoD PKI certificate. | In a properly configured DBMS, access controls defined for data access and DBMS management actions are assigned based on the user identity and job function. Unauthenticated or falsely... |
| V-3817 | Medium | Database accounts should not specify account lock times less than the site-approved minimum. | The FAILED_LOGIN_ATTEMPTS value limits the number of failed login attempts allowed before an account is locked. Setting this value limits the ability of unauthorized users to guess passwords and... |
| V-3815 | Medium | New passwords should be required to differ from old passwords by more than four characters. | Changing passwords frequently can thwart password-guessing attempts or re-establish protection of a compromised DBMS account. Minor changes to passwords may not accomplish this as password... |

| V-15626 | Medium | Database privileged role assignments should be restricted to IAO-authorized DBMS accounts. | Roles assigned privileges to perform DDL and/or system configuration actions in the database can lead to compromise of any data in the database as well as operation of the DBMS itself. Restrict... |
| V-15627 | Medium | Administrative privileges should be assigned to database accounts via database roles. | Privileges granted outside the role of the administrative user job function are more likely to go unmanaged or without oversight for authorization. Maintenance of privileges using roles defined... |
