Overview

What the CERT-IN directions require

CERT-IN is India’s national agency for incident response, designated under section 70B of the Information Technology Act, 2000. On 28 April 2022 it issued directions under section 70B(6) to strengthen incident response and the information available to investigate incidents. They took effect 60 days later and remain the core cyber security obligations for most organisations operating in India.

The directions are short but operationally demanding. Listed types of cyber incidents must be reported to CERT-IN within six hours of noticing them or being told about them. Logs of all ICT systems must be enabled and kept securely for a rolling 180 days within India. System clocks must be synchronised with the NTP servers of the National Informatics Centre or the National Physical Laboratory, or with sources traceable to them. Every covered organisation must name a point of contact for CERT-IN and act on CERT-IN’s orders for incident response.

Some providers carry extra record-keeping duties. Data centres, virtual private server providers, cloud service providers and VPN service providers must keep validated subscriber records for five years or longer. Virtual asset service providers, exchanges and custodian wallet providers must keep KYC records and transaction records for five years. CERT-IN published FAQs in May 2022 to clarify how the directions apply, and extended some timelines to 25 September 2022.

CERT-IN has since issued further guidance that sits alongside the directions, including guidelines for government entities in June 2023, technical guidelines on software and other bills of materials, and Comprehensive Cyber Security Audit Policy Guidelines in July 2025. Sector regulators also build on the directions; for example, the RBI’s CTRRAF Directions require incidents to be reported to CERT-IN as well as to RBI.

Who it applies to

The directions apply to the following, wherever an incident involves computer resources in India:

  • Service providers
  • Intermediaries
  • Data centres
  • Body corporates, meaning companies and other commercial organisations
  • Government organisations
  • Data centres, VPS, cloud and VPN service providers, for the subscriber record-keeping duties
  • Virtual asset service providers, exchanges and custodian wallet providers, for KYC and transaction records

The FAQs clarify that individual users are not covered, and that the VPN subscriber record-keeping duty does not apply to enterprise or corporate VPNs. Check the current FAQs for how the directions apply to your organisation.

Structure

How the directions are organised

Six operative directions, two annexures, and the FAQs that explain them. Later CERT-IN guidelines are summarised at the end.

Direction (i)

Clock synchronisation

All ICT systems must connect to the NTP servers of the National Informatics Centre (NIC) or the National Physical Laboratory (NPL), or to servers traceable to them, for clock synchronisation. Organisations spread across geographies may use other accurate and standard time sources, provided they do not deviate from NPL and NIC.

Direction (ii)

Reporting cyber incidents within 6 hours

Incidents of the types in Annexure I must be reported to CERT-IN within 6 hours of noticing them or of being brought to notice. CERT-IN publishes the reporting channels and format on its website. The FAQs allow initial reports with the information available, followed by further details.

Annexure I

Reportable incident types

Twenty types of incident, described here in summary.

Targeting and compromise
Targeted scanning or probing of critical networks and systems; compromise of critical systems or information; unauthorised access to IT systems or data.
Websites and malicious code
Website defacement or intrusion, including insertion of malicious code or links; malicious code attacks, such as viruses, worms, trojans, bots, spyware, ransomware and cryptominers.
Infrastructure and availability
Attacks on servers, such as database, mail and DNS, and on network devices such as routers; denial of service and distributed denial of service attacks.
Identity and deception
Identity theft, spoofing and phishing attacks.
Critical infrastructure and OT
Attacks on critical infrastructure, SCADA and operational technology systems, and wireless networks.
Applications and data
Attacks on applications such as e-governance and e-commerce; data breaches; data leaks.
Devices, payments and mobile
Attacks on IoT devices and associated systems; attacks or incidents affecting digital payment systems; attacks through malicious mobile apps; fake mobile apps.
Social media
Unauthorised access to social media accounts.
Cloud and emerging technology
Attacks or suspicious activity affecting cloud computing systems; big data, blockchain, virtual assets and their exchanges and wallets, robotics, 3D and 4D printing, additive manufacturing and drones; and artificial intelligence and machine learning systems.
Direction (iii)

CERT-IN orders and point of contact

Organisations must take action, provide information or give other assistance as CERT-IN orders for cyber incident response, mitigation and situational awareness, within the time it specifies. Each must designate a point of contact to liaise with CERT-IN, and send the details in the Annexure II format, keeping them up to date.

Direction (iv)

Logs for a rolling 180 days

Logs of all ICT systems must be enabled and maintained securely for a rolling period of 180 days within Indian jurisdiction. They must be provided to CERT-IN with an incident report or when CERT-IN orders. The FAQs give an indicative list of the logs to keep, which depends on the organisation’s systems.

Direction (v)

Subscriber records for infrastructure providers

Data centres, VPS providers, cloud service providers and VPN service providers must register and keep accurate subscriber information for five years or longer as the law requires, even after a registration is cancelled or withdrawn.

Records to keep
Validated names of subscribers or customers hiring the services; period of hire with dates; IPs allotted and being used; email address, IP address and time stamp used at registration; purpose of hiring; validated address and contact numbers; and ownership pattern.
Direction (vi)

Virtual asset KYC and transaction records

Virtual asset service providers, exchanges and custodian wallet providers must keep KYC information and records of financial transactions for five years, in line with the KYC norms of RBI, SEBI and the Department of Telecommunications. Transaction records must be detailed enough to reconstruct each transaction, including IP addresses, time stamps and time zones, transaction IDs, public keys, addresses or accounts involved, and the nature, date and amount of the transfer.

Implementation roadmap

How to implement it, step by step

A practical route to meeting the directions. Most of the work is in detection, logging and the ability to report quickly.

  1. 1

    Confirm how the directions apply

    Decide which categories your organisation falls into, including whether you are a data centre, cloud, VPS or VPN provider, or a virtual asset service provider, which carry extra duties.

    OutputsApplicability note
  2. 2

    Name the point of contact

    Designate a point of contact and a backup, send the details to CERT-IN in the Annexure II format, and keep them current when people change.

    OutputsPoint of contact recordSubmission to CERT-IN
  3. 3

    Synchronise clocks

    Point all ICT systems, including cloud workloads and network devices, to NIC or NPL NTP servers or to sources traceable to them, and check for drift.

    OutputsTime source configurationDrift checks
  4. 4

    Enable and retain logs

    Identify the logs each system must produce, enable them, and keep them securely for a rolling 180 days within India. Test that logs can be retrieved quickly.

    OutputsLog inventoryRetention configurationRetrieval test
  5. 5

    Build the six-hour reporting process

    Map Annexure I to your incident classification, record the time each incident is noticed, define who decides and who reports, and keep the reporting format ready.

  6. 6

    Set up provider records, if applicable

    Infrastructure providers set up validated subscriber records kept for five years. Virtual asset providers set up KYC and transaction records that allow each transaction to be reconstructed.

    OutputsSubscriber record processKYC and transaction records
  7. 7

    Exercise, audit and improve

    Run incident exercises against the six-hour target, audit logging and time synchronisation, and close the gaps found.

    OutputsExercise reportsCorrective actions

Audit and evidence guide

What auditors look for, and the evidence to keep

The directions do not set up a certification. Compliance is tested when an incident happens, when CERT-IN asks for information, and through audits by sector regulators, internal audit or CERT-IN empanelled auditors.

When an incident happens

  1. Step 1

    Notice and record the time

    The six-hour window runs from noticing the incident or being told about it, so the time must be recorded.

  2. Step 2

    Classify against Annexure I

    Decide whether the event falls within one of the 20 reportable types.

  3. Step 3

    Report to CERT-IN within 6 hours

    Report through CERT-IN’s published channels with the information available, and follow up with details.

  4. Step 4

    Provide logs and information

    Provide logs and other information when reporting or when CERT-IN orders, and act on its directions within the time it sets.

What reviewers look for

  • A current point of contact registered with CERT-IN
  • Time synchronisation with NIC or NPL sources across all ICT systems
  • Logs enabled for all ICT systems, retained for 180 days within India and retrievable
  • An incident classification that covers all 20 Annexure I types
  • Records showing when each incident was noticed and when it was reported
  • Copies of reports sent to CERT-IN and follow-up correspondence
  • Responses to CERT-IN orders within the time specified
  • Subscriber records kept for five years, for infrastructure providers
  • KYC and transaction records kept for five years, for virtual asset providers

Areas that often need attention

  • No reliable record of when an incident was first noticed, so six-hour reporting cannot be shown
  • Point of contact left with someone who has moved on
  • Logs enabled on servers but not on network devices, cloud services or SaaS
  • Logs kept for less than 180 days, or kept where they cannot be retrieved quickly
  • Some systems still synchronising to default public time sources
  • Incident classification that does not cover all Annexure I types, such as fake mobile apps or social media account takeover
  • Third parties that operate systems for you not contracted to notify you fast enough to meet six hours

How Netra helps

Where each part of the work lives in Netra

Netra loads the CERT-IN directions as requirements, tasks and policies, so readiness work, checks and evidence stay on one record.

Each duty owned and checked

Task Engine

Requirements arrive as tasks with owners and due dates. Recurring tasks cover point of contact reviews, time synchronisation checks and log retention checks.

Readiness status

Compliance Centre

Status is derived from completed tasks and evidence. The same work counts towards RBI CTRRAF and other frameworks where they overlap.

Incident response and logging policies

Policy Hub

A policy library generated at onboarding, with a score that moves as the work behind each policy is completed.

Knowing which systems must log and sync time

Asset Management

Assets linked to tasks, so teams can see which systems have been checked.

Third parties that run your systems

Third-Party Risk

Find vendors from what Accounts and Purchase pay, assess them through a vendor portal and record each decision with a rating.

Audits and exercise findings

Audit Centre

Run internal and regulatory audits end to end with findings and corrective actions, with evidence in a tamper-evident vault.

Reporting to management

Dashboard & Reports

A live Posture Score and a one-click board report for the framework.

Netra organises readiness work and evidence. It is not a SIEM, a log storage service or a reporting channel to CERT-IN, and it does not by itself establish compliance. Incident reports must be made to CERT-IN through its own channels.
