Revision summary
Social media is a never-closed square that can warn and also radicalise. It helps national security as early warning, official counter-narrative, community desks, and open-source intel. Encrypted plots and adversary propaganda set a hard ceiling; viral is not verified. IT Act due process, CERT-In, and staffed police cells decide whether the tool is lawful and useful. It is an auxiliary, not a substitute for classified intelligence and street policing.
Model answer
Introduction
Social media is a public square that never closes. For national security it is both a sensor and a weapon: the same feed that warns a flood or a riot can also radicalise a teenager or stampede a market. How far it helps depends on whether the State uses it as intelligence, communication, and counter-narrative — under law — rather than as a substitute for policing or as a licence for bulk surveillance.
Body
Where it strengthens security
- Early warning: open posts, geotags, and citizen video can flag a gathering, a border rumour, a disaster, or a fake terror claim faster than a beat constable’s notebook.
- Counter-narrative: official handles of MHA, PIB, and State police can kill a communal or panic rumour with a timestamped fact, which is cheaper than a curfew after the fact.
- Community policing: missing-child, traffic, and cyber-fraud desks on platforms recover people and money; trust is a security asset.
- Open-source intelligence: analysts can map protest mood, disaster needs, and sometimes a propagandist’s network — a supplement to classified intel, not a replacement.
- Recruitment and morale: the armed forces and police use the same channels to attract talent and to show a lawful face after an operation.
How far — the hard ceiling
- Encrypted closed groups and dark apps sit off the public square; the most dangerous plot may never trend.
- Adversaries use the same tools for radicalisation, deepfakes, and coordinated inauthentic behaviour; the platform is dual-use.
- A rumour can travel faster than a verification cell; 2010s lynchings and panic forwards showed that “viral” is not the same as “true.”
- Legal process (IT Act, blocking under due procedure, court warrants) must gate takedowns; a security claim without a paper trail becomes a free-speech wound that recruiters exploit.
- CERT-In incident response, cybercrime reporting (later I4C/1930 architecture), and police social-media cells work only if they are staffed and trained; a handle without a night desk is theatre.
Social media is therefore a significant auxiliary for national security — warning, narrative, and open-source — not a shield. The distance it can go is the distance of law, literacy, and a 24-hour verification room.

Conclusion
Social media can strengthen national security as early warning, counter-rumour, community desk, and open-source support. It cannot replace intelligence agencies or encrypted-plot policing. How far it helps is set by due-process takedowns, CERT-In and cybercrime cells, and public literacy against radical and panic content.

-
Can social media replace intelligence agencies?
No. It is open-source and public. Plots in closed encrypted rooms still need classical intelligence and warrants.
-
Does blocking every rumour strengthen security?
Only with due process and a verification desk. Blanket blocking without a paper trail feeds distrust and recruitment.

Explain with examples the role of science and technology in enhancing national power.
Science and technology in daily life
National power is military, economic, and legitimacy capacity; S&T now sits in all three. Nuclear and space programmes illustrate strategic autonomy after 1998 and ISRO/NavIC. Agronomy and pharma cut food and health vulnerability. Digital rails and IT enlarge fiscal reach and export skill. Power follows organised use of knowledge, not laboratory prestige alone.

Analyse corruption as a threat to internal security.
Internal security
Internal security needs order, borders, and public consent; corruption attacks all three. Bribes move arms, narcotics, and wanted persons through police and customs posts. Graft in recruitment and procurement creates insiders and hollow equipment. Lost trust in FIR and welfare is recruited by crime and extremist networks. Lokpal, CVC, DBT, e-procurement, and fast uniformed trials are security tools, not only ethics.

'Armed Forces Special Powers Act' of the Parliament of India has come under criticism by the States as being draconian and sometimes as unconstitutional. Examine analytically.
Economic planning and NITI Aayog
AFSPA 1958 notifies a disturbed area and gives armed forces fire, search, and arrest powers. Section 6 prior sanction is criticised as de facto immunity. States say law and order is theirs, yet the Army overlays policing for years. NPMHR 1997 upheld the Act with review and dos-and-don’ts; EEVFAM 2016 denied encounter immunity. Jeevan Reddy 2005 found the Act too sweeping; validity on paper is not the same as justice on the ground.
