π SEBIβs IT Resilience Index (ITRI)
π Why in News?
π’ SEBI has introduced the IT Resilience Index (ITRI) for Market Infrastructure Institutions (MIIs).
π What is ITRI?
π’ A quantitative regulatory scorecard to assess the technological resilience of critical capital-market infrastructure.
π’ Measures cybersecurity, fault tolerance, reliability and disaster-recovery capabilities.
π’ Similar to how capital adequacy ratios assess financial health in banking, ITRI measures digital resilience in capital markets.
π Key Features
π’ Uses a 9-parameter weighted framework to quantitatively benchmark IT resilience.
π’ Availability β 20% and Cybersecurity β 20% are the major parameters.
π’ Business Continuity β 10% and Reliability β 10% assess recovery capabilities.
π’ Scalability β 5% evaluates the ability to handle sudden transaction-volume surges.
π’ Requires an automated Early Warning System (EWS) to detect performance degradation, latency spikes and hardware stress.
π Objective
π’ Ensure trading, clearing, settlement and depository systems can withstand, absorb and recover from cyberattacks, software failures, operational shocks and transaction surges.
π Significance
π’ Shifts regulation from static compliance to measurable digital resilience.
π’ Helps prevent failures at exchanges and depositories from creating systemic financial disruptions.
π’ Complements SEBIβs technology roadmap covering AI/ML, SupTech/RegTech and quantum-safe cryptography.
π― Prelims Pointers
π’ Regulator: SEBI
π’ Index: IT Resilience Index (ITRI)

π DGFT Enables Automated Issuance of Free Sale and Commerce Certificates
π Why in News?
π’ The Directorate General of Foreign Trade (DGFT) has automated the issuance of Free Sale and Commerce Certificates (FSCs) for eligible applications, replacing manual scrutiny with rule-based processing.
π What is an FSC?
π’ An FSC certifies that a product is freely sold and commercially available in the country of manufacture.
π’ It is commonly required by importing countries for products such as food, nutraceuticals, agri-products, cosmetics, herbal preparations and chemicals.
π’ In India, FSCs are issued by DGFT Regional Authorities (RAs) for eligible items outside the Drugs & Cosmetics Act, 1940.
π What has Changed?
π’ Earlier: All applications underwent manual scrutiny by Regional Authorities, causing delays of several days to weeks.
π’ Now: Eligible applications are checked against an automated rule-set on the DGFT portal and certificates are issued immediately.
π’ Applications requiring verification are routed to the concerned RA.
π’ Auto-approved applications may later be reviewed under a risk-management framework.
π Key Shift
π’ Manual gate β Risk-based digital processing
π’ The system enables instant clearance for compliant exporters while human scrutiny is focused on risk-flagged applications.
π Significance
π’ Reduces processing time and compliance burden.
π’ Improves predictability and ease of doing business.
π’ Supports paperless and digital trade facilitation.
π’ Complements systems such as ICEGATE and SWIFT.
π’ Advances the objectives of the National Trade Facilitation Action Plan (NTFAP) and Indiaβs commitments under the WTO Trade Facilitation Agreement.
π Challenges
π’ Automation depends on a well-designed eligibility rule-set.
π’ Weak ex-post verification could reduce regulatory oversight.
π’ Small exporters may face digital-readiness challenges.
π’ Adequate support is needed to ensure that benefits also reach MSMEs and smaller exporters.
π About DGFT
π’ DGFT implements Indiaβs Foreign Trade Policy and issues IEC, Advance Authorisations, EPCG licences and trade-related certificates.
π Key Takeaway
π’ The automation of FSCs reflects a shift towards technology-driven and risk-based trade governance, with routine applications cleared digitally and regulatory scrutiny focused on higher-risk cases.
πΉ UPSC Mains Question:
βThe automation of Free Sale and Commerce Certificates reflects Indiaβs shift from front-end manual controls towards risk-based digital trade facilitation. Examine its significance and the challenges in ensuring equitable benefits for small and medium exporters.β

π Reverse Vaccinology: A New Approach to Vaccine Discovery
π Why in News?
π’ British scientists have taken an important first step towards developing a universal pneumococcal vaccine using reverse vaccinology.
π What is Reverse Vaccinology?
π’ A vaccine-discovery approach that starts in silicoβusing a pathogenβs genetic informationβrather than beginning with laboratory experiments on the pathogen itself.
π’ The term βreverse vaccinologyβ was coined by Rino Rappuoli in 2000.
π’ It integrates genomics, bioinformatics, proteomics and immunology.
π How does it work?
π’ Genome sequencing: Scientists obtain information about the pathogenβs genes and proteins.
π’ Computer-based screening: Bioinformatic tools identify genes capable of producing suitable surface proteins.
π’ Antigen selection: Proteins are selected based on accessibility to the immune system and minimal similarity to human proteins.
π’ Further assessment: Their predicted shape, stability and ability to generate a strong and lasting immune response are evaluated.
π’ Experimental validation: Promising candidates are tested through laboratory assays or in animals to determine whether they trigger immunity and provide protection.
π Why is it Significant?
π’ Faster vaccine discovery: Reduces the time required to identify suitable antigens compared with conventional approaches.
π’ Useful for difficult pathogens: Can support vaccine development where pathogens cannot be easily grown in culture.
π’ Wider coverage: Helps identify proteins shared across different serotypes, potentially enabling broad-spectrum or universal vaccines.
π’ Targeted approach: Narrows down potential vaccine targets before extensive laboratory experimentation.
π Major Applications
π’ First used for: Vaccine development against Neisseria meningitidis.
π’ COVID-19: Genome sequencing helped identify the gene encoding the spike protein for vaccine development.
π’ Pneumococcal disease: Scientists are now exploring shared protein targets to develop a universal pneumococcal vaccine.
π Limitations
π’ Cannot directly identify carbohydrates and other cellular structures that are not directly encoded by the genome.
π’ Computational predictions must ultimately be validated experimentally for safety and effectiveness.
π Prelims Takeaway
π’ Reverse Vaccinology: Starts with the genome of the pathogen β identifies potential antigens computationally β validates them experimentally.
π’ Conventional vaccinology: Traditionally begins with the pathogen itself, followed by identification of suitable antigens.
