Yes, they are.
But it also depends on which stage of the exam you are looking at.
They are very much relevant from the point of view of interview and mains. Since mains is in October it falls within the timeframe within that which questionscan be asked. These are also important because they are part of the syllabus in GS 2 and GS 3. It will make your answers on Security much more relevant and thorough.
For this year’s interview you should be thorough about these issues. For next year just knowing it should do. After that it won’t matter that much probably.
For prelims, you needn’t bother about these issues much.
The basic principle to keep in mind is simple. If they are testing you subjectively it matters. If not, it doesn’t.
