ISC2 SSCP Exam - Topic 7 Question 104 Discussion

Actual exam question for ISC2's SSCP exam
Question #: 104
Topic #: 7
[All SSCP Questions]

Which of the following is used in database information security to hide information?

Show Suggested Answer Hide Answer
Suggested Answer: B

Polyinstantiation enables a relation to contain multiple tuples with the same primary keys with each instance distinguished by a security level. When this information is inserted into a database, lower-level subjects need to be restricted from this information. Instead of just restricting access, another set of data is created to fool the lower-level subjects into thinking that the information actually means something else.

Inheritance sounds familiar, but I can't recall if it's about hiding data or something else entirely.

Okay, I've got this. Polyinstantiation is the technique used to create multiple versions of the same data object with different security classifications. That's the one that hides information in a database.

I'm a bit confused on the difference between polymorphism and polyinstantiation. I'll need to review those concepts before answering this.

Polyinstantiation - that's the one that allows multiple instances of the same object with different security levels, right? I think that might be the answer here.

Hmm, this looks like a tricky one. I'll need to think carefully about the different database security concepts and which one is specifically used to hide information.

Wait, is this a trick question? Maybe they're testing if we know the difference between database design patterns and actual security measures. *chuckles*
