Every entity that handles Aadhaar authentication or e-KYC data operates under a direct security obligation to the UIDAI. Whether you are an AUA, KUA, Sub-AUA, Sub-KUA, ASA, or KSA, the UIDAI mandates a periodic security audit of your systems and processes as a condition of continued API access and licensing. Cybernerds conducts these audits independently, with findings based on evidence collected during the engagement.

Why This Audit Exists

Aadhaar authentication and e-KYC pipelines carry biometric and demographic identity data of over a billion individuals. The UIDAI holds every entity in its ecosystem from large banks to fintech platforms to a defined security standard. A periodic ASA/KSA security audit is not optional. It is a licensing requirement, and an adverse finding or lapse in audit compliance can result in suspension of UIDAI API access, contract termination, or regulatory action under the Aadhaar Act.

Beyond the regulatory obligation, the audit provides an independent verification that the controls protecting Aadhaar-linked transactions in your environment are functioning as intended.

Who Needs This Audit

  • ASA (Authentication Service Agency) — Entities routing authentication packets between AUAs and the CIDR
  • KSA (KYC Service Agency) — Entities managing the technical pipeline for e-KYC data delivery from UIDAI to KUAs
  • What Cybernerds Evaluates

Our audit covers the full range of controls prescribed under the UIDAI's security framework. Below are the principal areas we assess:

  • Authentication pipeline security
  • Data storage and retention V
  • Access control and privilege management
  • Network and infrastructure security
  • Key and certificate lifecycle
  • Incident response and logging
  • Third-party and Sub-entity oversight
  • Physical and environmental security

Common Gaps We Find

These are not hypothetical risks. These are recurring observations from ASA/KSA audit engagements:

  • Aadhaar numbers or partial PII retained in application logs, databases, or debug outputs beyond the mandated purge window
  • Cryptographic keys stored in software keystores without HSM protection, particularly in on-premise deployments
  • Outdated or expired UIDAI certificates in the authentication chain, creating potential interception exposure
  • No formal security obligations or periodic review mechanisms in place for Sub-AUA or Sub-KUA entities
  • Incomplete or missing security event logs for authentication transactions, making post-incident analysis impractical
  • Incident response procedures that are generic IT policies with no specific provisions for Aadhaar ecosystem breaches

How We Conduct the Audit

Our audit follows a structured, evidence-based methodology across five phases:

1. Scope definition and document review We begin with a review of your UIDAI agreement, system architecture documentation, data flow diagrams, and the security policies governing your Aadhaar operations.

2. Technical configuration and controls assessment We evaluate system configurations, network architecture, cryptographic implementations, and access control settings through a combination of evidence collection, configuration review, and walkthrough sessions with your system owners.

3. Evidence mapping and gap analysis Each control requirement is mapped against the evidence collected. Gaps are classified with clear references to the applicable UIDAI requirement and the observed deviation.

4. Reporting and certification We issue a detailed audit report with control-level observations. Where the audit outcome supports a compliance determination, a compliance certificate is issued for submission to UIDAI.

  • Not Sure If You Are Fully Prepared?

Before the audit begins, it helps to know what documentation, configurations, and process records you will need to have ready. We have put together a preparation guide that walks you through exactly that.

Audit Deliverables

Every ASA/KSA audit engagement with Cybernerds produces the following:

  • Detailed audit report — Control-level findings with observations, evidence references, and risk classification
  • Evidence mapping document — Control-to-evidence mapping aligned to the UIDAI security framework
  • Compliance certificate — Issued where audit findings support a compliance determination, for submission to UIDAI

The compliance certificate is issued solely on the basis of audit findings. It is not a pre-determined outcome of the engagement.

  • About Cybernerds

Cybernerds is a CERT-In empanelled information security auditing organisation. We conduct ASA/KSA audits independently — our findings are based entirely on evidence collected during the audit.

Organisations across banking, fintech, telecom, and government programs rely on Cybernerds for security audits that stand up to regulatory scrutiny.
