Understanding India's New Data Protection Law: Implications for Network Security


India has taken a decisive step toward strengthening digital privacy with the enactment of the Digital Personal Data Protection (DPDP) Act, 2023. As this law moves toward implementation in 2025, organizations must reevaluate their network security architecture to ensure compliance and resilience.


In this blog, we decode the key provisions of the DPDP Act, its impact on network security, and actionable steps your organization can take to align with the new regulatory landscape.


What Is the DPDP Act?


The Digital Personal Data Protection Act, 2023 is India's first comprehensive law focused solely on digital personal data. It establishes rules around how personal data is collected, stored, processed, and transferred — both by Indian and foreign entities handling Indian citizens' data.


Key Elements:


  • Consent-based processing: Data must be collected with clear, informed user consent.

  • Purpose limitation: Data must only be used for the purpose stated during collection.

  • Data fiduciaries (organizations) are responsible for security and accountability.

  • Heavy penalties: Fines can reach ₹250 crore (~USD 30M) for data breaches or non-compliance.


Why Network Security Is Core to DPDP Compliance?


While DPDP is a privacy law, enforcement hinges on technical safeguards — particularly network and data security. Any compromise in network defenses can lead to unauthorized access, exfiltration, or misuse of personal data.


Here's how the law links to network security:

DPDP Requirement 

Network Security Implication 

Secure processing of data 

Encrypted data in transit and at rest 

Prevent unauthorized access 

Access control, firewalls, micro segmentation 

Detect and respond to breaches 

IDS/IPS, SIEM, SOC integration 

Retention and deletion policies 

Logging, data lifecycle management tools 

Cross-border data safeguards 

VPN, DLP, Zero Trust Access 

5 Network Security Areas Impacted by DPDP


  1. Data in Transit Must Be Encrypted


DPDP requires data to be handled securely — especially during transmission.


Recommendation:


  • Use TLS 1.3 or higher for all web apps and APIs.

  • Enforce IPSec tunnels or SSL VPNs for inter-office communications.

  • Inspect for plaintext traffic using network traffic analysis tools.


  1. Access Controls and Segmentation


Unauthorized internal access is as risky as external threats.


Recommendation:


  • Implement role-based access control (RBAC) and Zero Trust Network Access (ZTNA).

  • Apply network segmentation to isolate sensitive data environments.

  • Use multi-factor authentication (MFA) for all privileged users.


  1. Breach Detection and Logging


DPDP mandates breach notification — which requires prompt detection and forensic visibility.


Recommendation:


  • Deploy Intrusion Detection Systems (IDS) and Security Information and Event Management (SIEM).

  • Retain network logs for at least 12 months, aligned with compliance best practices.

  • Integrate 24/7 monitoring via a Security Operations Center (SOC).


  1. Data Residency and Cross-border Transfer


The Act allows international data transfers, but only to countries notified by the Indian government. Network paths must be secure.


Recommendation:


  • Identify data flows to/from cloud regions and external SaaS platforms.

  • Use Data Loss Prevention (DLP) tools at network and endpoint layers.

  • Secure all external traffic via SASE architecture with policy-based routing.


  1. Incident Response Readiness


DPDP requires prompt reporting of data breaches to the Data Protection Board of India (DPBI).


Recommendation:


  • Maintain a Network Security Incident Response Plan (NSIRP).

  • Simulate attacks and breaches via tabletop exercises.

  • Define clear playbooks for breach containment, forensics, and legal reporting.


  1. DPDP Compliance ≠ Only IT’s Job


Compliance requires alignment across teams:


  • Legal & Compliance: Define data classification and consent framework

  • IT & Security: Build and monitor network safeguards

  • HR & Admin: Enforce device policies for BYOD and remote users

  • Leadership: Assign a Data Protection Officer (DPO), if applicable
