CERT-In Directive Explained: Why Cyber Incidents in India Require a Forensic Investigation Report
India’s digital ecosystem is growing at an unprecedented
pace. With rapid cloud adoption, fintech innovation, SaaS expansion, and
large-scale digital public infrastructure, cyber incidents are no longer exceptions
- they are inevitable. What differentiates a resilient organization from
a vulnerable one is how it responds after an incident occurs.The CERT-In Directive has fundamentally changed the
way Indian organizations must handle cybersecurity incidents. It makes one
thing very clear:Fixing the problem is not enough. You must investigate
it.A cyber incident without a digital forensic investigation
report is now a compliance risk, a legal exposure, and a business
liability.This blog explains the CERT-In directive in simple terms,
why forensic reporting is critical, and how Indian organizations should align
their incident response strategy to avoid penalties, reputational damage, and
repeat attacks.Understanding the CERT-In Directive CERT-In (Indian Computer Emergency Response Team) is the
national authority responsible for responding to cybersecurity incidents under
the Information Technology Act, 2000.Under the latest directive, organizations operating in India
must:
Report
specific cyber incidents within 6 hours
Maintain
ICT logs for at least 180 days
Provide
logs and investigation data to CERT-In on demand
Preserve
evidence related to cyber incidents
This applies to:
Enterprises
and MSMEs
Cloud
service providers
Data
centers and VPN providers
Fintech,
healthcare, IT/ITES, and e-commerce companies
The directive shifts the focus from reactive fixing
to structured investigation and accountability. The Common Mistake: “We Fixed It, So We’re Done”After a cyber incident, many organizations focus on:
Blocking
the compromised account
Rebuilding
the affected server
Resetting
passwords
Applying
patches
While these steps are necessary, they are incomplete.From CERT-In’s perspective, the following questions still
remain unanswered:
How
did the attacker gain access?
When
did the breach actually start?
What
systems, data, or credentials were affected?
Was
it an external attack or an insider threat?
Are
there persistence mechanisms still active?
Is
the organization at risk of recurrence?
Without a forensic investigation report, you cannot
answer these questions - and CERT-In can demand those answers. Why CERT-In Expects a Forensic Report, Not Just a
Technical Fix1. To Establish the Root Cause of the IncidentA fix addresses the symptom.
A forensic investigation identifies the root cause.Example:
Fix:
Disable a compromised VPN account
Forensics:
Determine whether credentials were phished, brute-forced, reused, or
stolen via malware
CERT-In expects organizations to understand how the
incident happened, not just where it was noticed. 2. To Determine the True Impact of the BreachMany breaches go undetected for weeks or months.A forensic report helps establish:
Initial
point of compromise
Lateral
movement across systems
Data
accessed, altered, or exfiltrated
Logs
showing attacker activity timeline
This is critical for:
Regulatory
disclosure
Customer
notification
Legal
defense
3. To Preserve Digital EvidenceCERT-In directives align closely with legal and law
enforcement expectations.A proper forensic investigation ensures:
Evidence
integrity (hash values, chain of custody)
Non-tampering
of logs and systems
Documentation
suitable for courts and regulators
Ad-hoc fixes often destroy evidence, creating compliance
and legal risk. 4. To Prove Due Diligence and ComplianceIn the event of:
CERT-In
audits
Sectoral
regulator scrutiny (RBI, SEBI, IRDAI)
Cyber
insurance claims
Legal
disputes
A forensic report demonstrates:
Timely
incident response
Structured
investigation
Responsible
data handling
This can significantly reduce penalties and liability. What a CERT-In-Aligned Forensic Report Should IncludeA professional cyber forensic investigation report
typically covers:Incident Overview
Date
and time of detection
Systems
affected
Nature
of the incident
Scope of Investigation
Servers,
endpoints, cloud workloads
Network
devices
Logs
analyzed
Technical Findings
Entry
vector and attack path
Compromised
accounts or services
Indicators
of compromise (IOCs)
Malware
or tools identified
Timeline Reconstruction
Initial
compromise
Privilege
escalation
Lateral
movement
Data
access or exfiltration
Impact Assessment
Data
affected
Business
systems impacted
Risk
to customers or partners
Remediation & Recommendations
Security
gaps identified
Preventive
controls suggested
Monitoring
improvements
This level of documentation is what CERT-In expects - not a
brief incident closure note. Log Retention and Forensics: A Critical ConnectionCERT-In mandates 180-day log retention for a reason.Without historical logs:
Forensic
timelines collapse
Attack
paths remain unclear
Incident
scope gets underestimated
Key logs required for forensic readiness include:
Firewall
and VPN logs
Authentication
and access logs
Server
and database logs
Cloud
audit trails
Endpoint
security logs
Organizations without centralized logging often struggle to
comply during an investigation. Industries at Higher Risk of CERT-In ScrutinyWhile the directive applies broadly, enforcement risk is
higher for:
IT
& ITES companies handling overseas data
Fintech
and BFSI organizations
Healthcare
and pharma companies
Cloud
service providers and SaaS platforms
Data
centers and managed service providers
For these sectors, a missing forensic report after an
incident can quickly escalate into a regulatory issue. Forensic Readiness: Preparing Before the IncidentThe smartest organizations don’t wait for a breach to think
about forensics.They invest in:
Incident
response playbooks
Centralized
log management
Forensic-ready
system configurations
Expert-led
investigation support
This ensures that when an incident occurs:
Evidence
is preserved
Reporting
timelines are met
Business
disruption is minimized
Why “Quick Fixes” Can Make Things WorseIronically, rushed remediation can:
Destroy
volatile evidence
Alert
attackers still present in the network
Mask
deeper compromise
Lead
to repeat incidents
CERT-In investigations often reveal that the second
breach happens because the first one was never fully understood.Final Thoughts: Compliance, Trust, and Long-Term SecurityThe CERT-In directive is not just a regulatory burden - it
is a maturity benchmark.Organizations that treat cyber incidents as:
“IT
issues” → struggle with compliance
“Risk
and forensic events” → build long-term resilience
A forensic investigation report is no longer optional
in India’s cybersecurity landscape. It is essential for:
Regulatory
compliance
Legal
protection
Customer
trust
Sustainable
security posture
If your incident response strategy ends with a fix, it’s
incomplete.If it ends with a forensic report, it’s defensible.At Proaxis Solutions, we believe a cyber incident is not just a technical disruption - it is a moment that tests an organization’s governance, accountability, and preparedness. Under the CERT-In directive, closing a ticket or restoring a system is only half the responsibility. What truly matters is understanding how the breach occurred, what was impacted, and whether your organization can defend itself against recurrence.Our digital forensics and incident response expertise helps organizations across India move beyond quick fixes to defensible, regulator-ready outcomes. Through structured forensic investigations, evidence-preserving methodologies, and CERT-In–aligned reporting, Proaxis Solutions ensures your incident response stands up to regulatory scrutiny, legal review, and board-level oversight.
In today’s threat landscape, resilience is built on clarity - not assumptions. And clarity begins with forensics.
