4.B and C Only
Solution
The correct answer is A and C Only
Key Points
A. A user can assign privileges to any user on any relation.
This statement is typically false. In most database systems, a user cannot assign privileges to others on relations (tables, views, etc.) they do not own unless they have been granted specific administrative rights.
B. A user can assign privileges to any user on its own relations only.
This statement is generally true. In most database systems, users can assign privileges on the relations they own.
C. System error that leads to accessibility to the portion of database is an example of malicious attack.
This statement is false. A system error leading to unintended access is typically considered a security vulnerability or accidental exposure rather than a malicious attack. A malicious attack implies intentional actions by an attacker.
D. Passwords itself need to be secured from unauthorized access.
This statement is true. Protecting passwords from unauthorized access is a fundamental security practice.
