All accounts must be assigned unique User Identification Numbers (UIDs).


Overview

Finding ID Version Rule ID IA Controls Severity
V-762 GEN000320 SV-44821r1_rule Medium
Description
Accounts sharing a UID have full access to each others' files. This has the same effect as sharing a login. There is no way to assure identification, authentication, and accountability because the system sees them as the same user. If the duplicate UID is 0, this gives potential intruders another privileged account to attack.
