What Does CERT-In Actually Require?

CERT-In's directions of 28 April 2022 apply to every organisation in India that operates an ICT system, with limited exceptions. The core obligations are: report cyber incidents to CERT-In within six hours of noticing them, including suspected incidents; keep logs of ICT system transactions for 180 days; implement an Information Security Management System; and have that system audited by a CERT-In empanelled auditor, at least once every three years, and after every major change. Virtual assets, cloud, and supply chain are all in scope.

Key takeaways

  • The 28 April 2022 directions require incident reporting within six hours of noticing an incident, and CERT-In has itself said that uncertainty about the full facts is not a reason to delay the first report.
  • Logs must be retained for 180 days, which in practice means shipping them off your servers to a write-once store or a SIEM, because disk retention on a single host is the usual failure point.
  • An ISMS is required, and it is not a document exercise: CERT-In's auditor checklist expects a written policy set, asset inventory, access control, incident management and continuous monitoring.
  • Audits must be done by a CERT-In empanelled auditor, at least once every three years, and again after any significant change to the ICT system.
  • Service providers and cloud data centres have their own obligations under the directions, including synchronised clocks and customer log access on demand.

Who do the CERT-In directions actually apply to?

The 28 April 2022 directions reach broadly: every organisation with an ICT system in India, in the public and private sector alike, and they extend to the body corporate that owns the system. Government agencies had 180 days to comply and private entities had a year, so the grace period has long expired. If you run servers, a network, a cloud tenancy or a managed service for a client, you are in scope. The carve-outs are narrow, such as purely domestic use of a computer.

What does the six-hour incident reporting duty involve?

The duty is to report to CERT-In within six hours of noticing an incident or a suspected incident, and to keep updating the report as facts become clearer. The report goes to the CERT-In incident reporting portal or the designated email address, and it must include the nature of the incident, the affected systems, the impact, and the mitigation taken or planned. CERT-In has stated that an incomplete report is acceptable and can be updated, so the practical instruction to your team is: report the suspicion, and do not sit on it for a forensic weekend.

What do the 180-day log retention rules mean in practice?

The directions require ICT system transaction logs to be retained for 180 days, produced on demand, and tamper-evident. In practice that rules out relying on a live server's local disk, because the log window there is usually days, not months. You need a central log store with immutability, and clock synchronisation across hosts so timestamps can be correlated. For a mid-sized Indian firm, the cheapest compliant pattern is a SIEM agent on servers and endpoints feeding a central tenant, plus an archive tier for the 180-day window.

What does the ISMS and audit requirement look like?

The directions require an Information Security Management System, a documented set of policies covering asset classification, access control, incident management, backup, human resource security and information security education, and a periodic audit by a CERT-In empanelled auditor. The audit cycle is at least once every three years, and again after a major change such as a new data centre or a new cloud provider. The empanelment scheme carries its own validity period and mandatory surveillance, so your auditor's certificate being current is part of your obligation, and budget the audit as an annual line item.

What are the frequently asked questions?

What does CERT-In actually require?
CERT-In's directions of 28 April 2022 apply to every organisation in India that operates an ICT system, with limited exceptions. The core obligations are: report cyber incidents to CERT-In within six hours of noticing them, including suspected incidents; keep logs of ICT system transactions for 180 days; implement an Information Security Management System; and have that system audited by a CERT-In empanelled auditor, at least once every three years, and after every major change. Virtual assets, cloud, and supply chain are all in scope.
Do I have to report a suspected incident before I have confirmed it?
Yes. The six-hour clock starts when you notice or suspect an incident, and CERT-In accepts an incomplete first report that is updated later. Waiting for full forensic confirmation is the single most common way organisations miss the window.
How long must I keep logs?
Logs of ICT system transactions must be retained for 180 days and produced on demand. That effectively rules out local disk logs, so most Indian firms move to a central SIEM with a 180-day archive tier.
How often must a CERT-In empanelled audit happen?
At least once every three years, and again after any significant change to the ICT system, such as a new data centre, cloud provider or network design.
Does the six-hour rule apply to ransomware?
Yes. Ransomware, credential compromise, exfiltration and suspected incidents in a vendor system holding your data all sit inside the six-hour reporting window.
