Prelims Strategy

For Prelims, a strong factual foundation is non-negotiable. Begin by memorizing the names of major foreign intelligence agencies (ISI, MSS, CIA, Mossad, SVR, MI6) and their primary countries. Crucially, understand their specific mandates and the nature of threats they pose to India.

For instance, ISI = cross-border terrorism, MSS = cyber/economic espionage. Next, focus on India's institutional responses: know the full forms, establishment year (if significant, like MAC post-Kargil), and primary functions of bodies like RAW, IB, MAC, JIC, NTRO, and NCIIPC.

Understand the legal framework: Official Secrets Act, UAPA, NSA – know their core provisions relevant to espionage and national security. Pay special attention to amendments (e.g., UAPA 2019) and landmark committee recommendations (Kargil Review Committee).

Create flashcards for key terms like HUMINT, SIGINT, OSINT, cyber espionage. Practice MCQs that test your ability to differentiate between agencies, identify correct functions of institutions, and recall legal provisions.

Vyyuha's Quick Recall mnemonic 'SPICE' will be invaluable here for categorizing threats. Focus on recent current affairs related to espionage cases or cyber attacks, linking them to the static syllabus.
