Quick Answer
An IT compliance audit is a systematic review of an organisation’s policies, processes, technology, security controls and records to determine whether they meet applicable legal, regulatory, contractual or industry requirements. Common audit frameworks include the Digital Personal Data Protection Act (DPDPA), ISO/IEC 27001, GDPR, HIPAA, IT General Controls (ITGC), TISAX and SOC 2.
These frameworks address different compliance objectives. DPDPA and GDPR focus on personal data protection and privacy. ISO 27001 provides an information security management system (ISMS). HIPAA establishes requirements for protecting certain health information in the United States. ITGC evaluates foundational IT controls. TISAX addresses information security requirements in the automotive industry, while SOC 2 assesses controls relevant to security, availability, processing integrity, confidentiality and privacy.
Organisations should identify which requirements apply to their business, assess existing controls, maintain supporting evidence, address gaps and periodically review compliance. Passing one audit does not automatically establish compliance with another framework.
1. What Is an IT Compliance Audit?
An IT compliance audit is an independent or internal examination of an organisation’s IT environment to verify whether its systems, processes and security controls comply with defined requirements.
The audit may examine:
- Information security policies and procedures.
- User accounts, access permissions and authentication.
- Data protection, privacy and information handling.
- Network, endpoint, server and cloud security.
- Backup, recovery and business continuity arrangements.
- Change management and software development controls.
- Security monitoring, logging and incident response.
- Vendor management and third-party access.
- Risk assessments and corrective actions.
- Employee awareness and security training.
The objective is to determine whether controls are appropriately designed, implemented and operating effectively. Depending on the audit type, the outcome may be an internal audit report, certification, attestation report, assessment result or regulatory compliance finding.
2. Digital Personal Data Protection Act (DPDPA)
2.1 What Is DPDPA?
The Digital Personal Data Protection Act, 2023 (DPDPA) is India's legislation governing the processing of digital personal data. It establishes obligations for organisations processing digital personal data and provides rights and protections for individuals, referred to in the Act as Data Principals.
The Act uses the term Data Fiduciary for an entity that determines the purpose and means of processing personal data. A Data Processor processes personal data on behalf of a Data Fiduciary.
Organisations should assess the Act, applicable rules, commencement notifications and relevant exemptions to determine which obligations apply to their operations at a given time.
2.2 Important DPDPA Concepts
- Data Principal: The individual to whom personal data relates.
- Data Fiduciary: The person or organisation that determines the purpose and means of processing personal data.
- Data Processor: An entity that processes personal data on behalf of a Data Fiduciary.
- Consent: Permission given by the Data Principal for processing, where consent is the applicable legal basis.
- Notice: Information provided to individuals about the personal data processing.
- Personal Data Breach: Unauthorised processing or accidental disclosure, acquisition, sharing, use, alteration, destruction or loss of access to personal data, as defined by the Act.
- Data Protection Board of India: The statutory body established under the Act to perform its assigned functions.
2.3 DPDPA Audit Requirements and Checks
A DPDPA compliance assessment should examine whether the organisation has implemented appropriate processes for handling digital personal data.
| Audit Area | What Should Be Checked? |
|---|---|
| Personal data inventory | Identify personal data collected, processed, stored and shared by the organisation. |
| Purpose of processing | Verify that personal data is processed for lawful and specified purposes. |
| Privacy notice | Review whether notices communicate the required information clearly. |
| Consent management | Check how consent is obtained, recorded, managed and withdrawn where applicable. |
| Data Principal rights | Review processes for handling applicable requests, including access to information, correction, erasure and grievance redressal. |
| Data security | Examine technical and organisational safeguards protecting personal data. |
| Data breach response | Verify incident detection, investigation, documentation and notification procedures. |
| Data retention | Check whether personal data is retained only as required and erased when applicable obligations are met. |
| Third-party processing | Review processor arrangements, contracts and security responsibilities. |
| Children's data | Assess additional requirements applicable to processing children's personal data. |
2.4 Evidence Required for a DPDPA Audit
- Personal data inventory and data flow diagrams.
- Privacy notices and consent records.
- Data processing agreements and vendor contracts.
- Data retention and deletion policies.
- Access control and encryption configurations.
- Incident response and personal data breach records.
- Grievance handling procedures and request logs.

- Records supporting applicable compliance assessments.
Important: DPDPA compliance should not be treated as a one-time certification exercise. Organisations should continuously review processing activities, legal requirements, security controls and applicable government notifications.
3. ISO/IEC 27001 Audit
3.1 What Is ISO 27001?
ISO/IEC 27001 is an international standard that specifies requirements for establishing, implementing, maintaining and continually improving an Information Security Management System (ISMS).
It helps organisations identify information security risks and implement controls to protect the confidentiality, integrity and availability of information.
ISO/IEC 27001 can be applied to organisations of different sizes and industries. Certification is performed by an independent certification body, where an organisation chooses to pursue certification.
3.2 Main Areas of an ISO 27001 Audit

5. HIPAA Audit
5.1 What Is HIPAA?
The Health Insurance Portability and Accountability Act (HIPAA) is a United States federal law that includes requirements for protecting certain health information. Its Privacy, Security and Breach Notification Rules establish important obligations for covered entities and business associates.
HIPAA is particularly relevant to healthcare providers, health plans, healthcare clearinghouses and business associates that handle protected health information (PHI) within the scope of the law.
5.2 What Is Protected Health Information?
Protected Health Information (PHI) is individually identifiable health information maintained or transmitted by a covered entity or business associate, subject to HIPAA's definitions and exclusions.
Examples can include:
- Patient names associated with medical information.
- Medical record numbers.
- Diagnosis and treatment information.
- Health insurance details.
- Billing information linked to healthcare services.
- Other identifying information associated with an individual's health condition or healthcare.
5.3 HIPAA Security Rule Audit Areas
The HIPAA Security Rule establishes administrative, physical and technical safeguards for electronic protected health information (ePHI).
| Safeguard Category | Audit Focus | Examples |
|---|---|---|

Covered entities and business associates should maintain documented procedures for identifying, investigating, assessing and reporting potential breaches. Applicable notification deadlines and responsibilities depend on the entity's role and the circumstances of the incident.
6. IT General Controls (ITGC) Audit
6.1 What Are ITGCs?
IT General Controls (ITGC) are foundational controls that support the reliable, secure and consistent operation of an organisation's IT environment. They help ensure that systems and data used in business operations and financial reporting are appropriately protected and managed.
ITGC audits are commonly performed as part of financial audits, internal audits, risk assessments and compliance reviews. They are particularly important when business processes depend on IT systems for transaction processing, financial reporting or data management.
6.2 Main Categories of ITGC
| ITGC Category | Purpose | Typical Audit Checks |
|---|---|---|
| Access Management | Ensure only authorised users can access systems and data. | User provisioning, role assignment, privileged access, periodic access reviews and termination procedures. |
| Change Management | Ensure system changes are authorised, tested and approved. | Change requests, approvals, testing evidence, deployment records and emergency changes. |
| IT Operations | Ensure IT services operate reliably. | Job monitoring, incident management, backups, scheduled tasks and system availability. |
| Backup and Recovery | Protect information and support restoration after failures. | Backup schedules, backup logs, restore tests and disaster recovery arrangements. |

| Security Administration | Maintain secure system configurations and administration. | Security settings, privileged accounts, vulnerability management and logging. |
6.3 User Access Management Audit
Access management is a major ITGC area because inappropriate access can result in unauthorised transactions, data exposure, fraud or changes to critical systems.
Auditors commonly verify:
- Every user account has an identifiable owner.
- Access is approved by authorised personnel.
- Users receive access appropriate to their job responsibilities.
- Privileged accounts are restricted and monitored.
- Access is removed promptly when employees leave.
- Access is modified when employees change roles.
- Shared and generic accounts are restricted and controlled.
- Periodic user access reviews are documented.
- Authentication controls are appropriate to system risk.
6.4 Change Management Audit
Change management controls help prevent unauthorised or untested modifications to applications, databases, servers and network infrastructure.
Audit evidence may include:
- Change request tickets.
- Business and technical approvals.
- Impact and risk assessments.
- Testing and user acceptance testing results.
- Segregation between development, testing and production environments.
- Deployment and rollback records.
- Emergency change approvals and retrospective reviews.
6.5 IT Operations Audit
- Review scheduled job execution and failure handling.
- Examine monitoring and alerting procedures.
- Check incident and problem management records.
- Verify backup completion and restoration testing.
- Review system availability and capacity monitoring.
- Check vulnerability and patch management records.
- Review operational procedures and responsibilities.
7. TISAX Audit
7.1 What Is TISAX?
TISAX stands for Trusted Information Security Assessment Exchange. It is an information security assessment and exchange mechanism developed for the automotive industry by the German Association of the Automotive Industry (VDA) and operated by the ENX Association.
TISAX helps automotive manufacturers, suppliers and service providers demonstrate information security practices against defined assessment requirements. It supports the exchange of assessment results between participating organisations.
7.2 Who Needs TISAX?
TISAX may be required or requested by organisations that work with automotive manufacturers or suppliers and handle sensitive automotive information.
Examples include:

8. SOC 2 Audit
8.1 What Is SOC 2?
SOC 2 (System and Organization Controls 2) is an attestation framework developed by the American Institute of Certified Public Accountants (AICPA). It evaluates controls at a service organisation relevant to one or more Trust Services Criteria.
SOC 2 is commonly requested from cloud service providers, SaaS companies, data centres, managed service providers and other technology organisations that handle customer information or deliver technology services.
A SOC 2 examination is performed by an independent licensed CPA firm. A SOC 2 report is not the same as an ISO 27001 certificate.
8.2 SOC 2 Trust Services Criteria
The SOC 2 Trust Services Criteria consist of five categories:
| Trust Services Category | Purpose | Example Controls |
|---|---|---|
| Security | Protect systems and information against unauthorised access and other security threats. | Access control, authentication, vulnerability management and security monitoring. |
| Availability | Ensure systems are available for operation and use as committed or agreed. | Uptime monitoring, backup, disaster recovery and capacity management. |
| Processing Integrity | Ensure system processing is complete, valid, accurate, timely and authorised. | Input validation, processing checks, error handling and reconciliation. |
| Confidentiality | Protect information designated as confidential. | Encryption, access restrictions, secure disposal and data classification. |
| Privacy | Address the collection, use, retention, disclosure and disposal of personal information in accordance with applicable privacy commitments and criteria. | Privacy notices, consent processes, data retention and individual request handling. |
The Security category is included in every SOC 2 examination. The organisation and its service users determine which additional categories are relevant to the services and commitments being examined.
8.3 SOC 2 Type I vs Type II
| Feature | SOC 2 Type I | SOC 2 Type II |
|---|---|---|
| Primary focus | Design of controls at a specified point in time. | Design and operating effectiveness of controls over a defined period. |

10. How These Frameworks Work Together
Although these frameworks have different objectives, many of their underlying controls overlap. An organisation can build a common information security and compliance programme to reduce duplicated effort while maintaining separate evidence for framework-specific requirements.
For example:
- ISO 27001 risk management can support security risk assessments required by other frameworks.
- ISO 27001 access controls can support relevant DPDPA, GDPR, HIPAA, ITGC and SOC 2 control objectives.
- Data inventory and data classification can support privacy and information security assessments.
- Incident management procedures can support applicable personal data breach and security incident obligations.
- Backup, recovery and continuity controls can support ISO 27001, ITGC, HIPAA, TISAX and SOC 2 requirements.
- Vendor risk management can support supplier security obligations across multiple frameworks.
- Change management evidence can support ISO 27001, ITGC, TISAX and SOC 2 assessments.
However, overlapping controls do not mean that the frameworks are interchangeable. Each framework has its own scope, definitions, legal or contractual requirements, assessment methods and evidence expectations.
11. Common Documents Required for IT Compliance Audits
Organisations should maintain a central repository of policies, procedures, records and technical evidence. The exact evidence required depends on the framework, audit scope and auditor's testing approach.
| Document or Record | Purpose |
|---|---|
| Information Security Policy | Defines management's security direction and organisational expectations. |
| Access Control Policy | Defines account creation, access approval, review and removal procedures. |
| Asset Inventory | Identifies hardware, software, information assets and responsible owners. |
| Risk Assessment | Identifies and evaluates risks to systems, information and business operations. |
| Data Inventory | Documents personal, confidential and business information handled by the organisation. |
| Data Retention Policy | Defines retention, archival and deletion requirements. |
| Incident Response Plan | Defines how security incidents are reported, investigated and resolved. |
| Business Continuity Plan | Describes how critical operations are maintained during disruptions. |
| Disaster Recovery Plan | Defines recovery procedures for IT systems and services. |
| Backup Policy | Defines backup frequency, retention, protection and restoration testing. |
| Change Management Policy | Defines the approval, testing and deployment of IT changes. |
| Vendor Management Policy | Defines how third-party security risks are assessed and monitored. |
| Employee Training Records | Demonstrates that employees receive relevant security and privacy awareness training. |
| Internal Audit Reports | Documents internal reviews, identified gaps and corrective actions. |
| Corrective Action Register | Tracks audit findings, owners, deadlines and closure evidence. |
12. Step-by-Step IT Compliance Audit Preparation
Step 1: Identify Applicable Frameworks
Determine which legal, regulatory, contractual and industry requirements apply to the organisation. Consider the location of operations, customer requirements, types of data processed and services delivered.
Step 2: Define the Audit Scope
Document the business units, locations, systems, applications, cloud services, processes and third parties included in the audit. A clear scope prevents important systems from being overlooked.
Step 3: Identify Information Assets
Create an inventory of information assets, including servers, endpoints, network devices, databases, applications, cloud resources and information repositories. Identify asset owners and data sensitivity.
Step 4: Perform a Gap Assessment
Compare existing policies, procedures and technical controls with the requirements of the selected framework. Record missing, incomplete or ineffective controls.
Step 5: Implement Required Controls
Develop or improve policies, processes and technical safeguards. Assign responsibilities and ensure that controls are implemented in the systems and business processes included in the audit scope.
Step 6: Collect Audit Evidence
Collect records that demonstrate how controls are designed and operated. Evidence should be accurate, complete, traceable and relevant to the audit period.
Step 7: Conduct an Internal Review
Perform internal testing before the formal audit. Check whether policies are followed, approvals are documented, configurations are appropriate and records are available.
Step 8: Address Identified Gaps
Assign each finding to a responsible owner. Define corrective actions, completion dates and evidence required for closure. Prioritise high-risk issues.
Step 9: Support the External Audit or Assessment
Provide requested documentation, system demonstrations, interviews and evidence to the auditor or assessment provider. Ensure that responses are consistent and supported by records.
Step 10: Maintain Continuous Compliance
Monitor changes to systems, business processes, suppliers and applicable requirements. Review controls periodically and track corrective actions until completion.

14. Common IT Compliance Audit Findings
| Audit Finding | Potential Risk | Recommended Corrective Action |
|---|---|---|
| Former employee accounts remain active. | Unauthorised access to systems and data. | Implement timely account termination and periodic access reviews. |
| Shared administrator accounts are used. | Reduced accountability and difficulty tracing activity. | Use individual privileged accounts and controlled emergency access. |
| Security patches are overdue. | Exposure to known vulnerabilities. | Implement risk-based patch management and exception tracking. |
| Backup restoration has not been tested. | Data may not be recoverable after a failure. | Conduct documented restoration tests at planned intervals. |
| Change approvals are missing. | Unauthorised or untested production changes. | Use a documented change management workflow. |
| Vendor security reviews are incomplete. | Third-party security and privacy risks may remain unmanaged. | Perform risk-based vendor assessments and periodic reviews. |
| Incident response procedures are outdated. | Delayed detection, escalation and recovery. | Update response plans and conduct exercises. |
| Privacy notices are incomplete. | Individuals may not receive required processing information. | Review notices against applicable privacy requirements. |
| Audit logs are not retained adequately. | Insufficient evidence for investigations and audit testing. | Define and enforce log retention and protection requirements. |
| Risk register is not updated. | New or changed risks may not be addressed. | Review risks periodically and after significant changes. |
15. How to Manage Audit Findings and Corrective Actions
Audit findings should be recorded in a structured register so that management can monitor remediation and verify that identified issues have been resolved.
A corrective action register should contain:
- Finding reference number.
- Audit framework and control reference.
- Description of the finding.
- Risk rating or severity.
- Root cause analysis.
- Corrective action and preventive action.
- Responsible person or department.
- Target completion date.
- Current status.
- Closure evidence.
- Reviewer or auditor validation.
Closing a finding should involve more than updating its status. The organisation should verify that the corrective action has been implemented and that the control is operating as intended.
16. Best Practices for Maintaining Continuous Compliance
- Maintain a central compliance register covering applicable laws, standards and customer requirements.
- Assign control owners and clearly define responsibilities.
- Keep policies and procedures current and approved.
- Automate evidence collection where practical.
- Review privileged and standard user access periodically.
- Monitor vulnerabilities, patches and system configurations.
- Test backups and disaster recovery arrangements.
- Maintain incident response and breach notification procedures.
- Review third-party security and privacy risks.
- Conduct internal audits and management reviews.
- Track corrective actions until their effectiveness is verified.
- Reassess compliance whenever significant business, technology or regulatory changes occur.
17. Frequently Asked Questions (FAQs)
Q1. What is the difference between an IT audit and an IT compliance audit?
An IT audit may examine the overall effectiveness, performance, security and governance of IT systems. An IT compliance audit specifically evaluates whether systems, processes and controls meet defined legal, regulatory, contractual or framework requirements. Some audits cover both areas.
Q2. Are ISO 27001 and SOC 2 the same?
No. ISO 27001 is an international standard for establishing and certifying an Information Security Management System. SOC 2 is an independent CPA examination and attestation report evaluating controls against selected Trust Services Criteria. Both address information security, but their requirements, scope and reporting methods differ.
Q3. Is ISO 27001 certification mandatory?
ISO 27001 certification is generally voluntary. However, a customer, contract, tender, regulator or business partner may require or strongly expect certification. Organisations should identify the requirements applicable to their specific industry and business relationships.
Q4. Does DPDPA apply to all businesses in India?
The Act applies according to its scope and provisions, including the nature of digital personal data processing and applicable exemptions. Organisations should assess their processing activities, legal responsibilities and applicable commencement notifications rather than assuming that every business has identical obligations.
Q5. What is the difference between DPDPA and GDPR?
Both address personal data protection, but they are separate legal frameworks. DPDPA is India's digital personal data protection legislation, while GDPR is the European Union's data protection regulation. Their terminology, legal requirements, rights, territorial scope and enforcement arrangements differ.
Q6. Does HIPAA apply to every company that stores medical information?
No. HIPAA applies to covered entities and business associates as defined by the law. Whether an organisation is subject to HIPAA depends on its role, activities and relationship with regulated entities. Other privacy or security laws may apply even when HIPAA does not.
Q7. What is the difference between ITGC and application controls?
ITGC are foundational controls supporting the overall IT environment, such as access management, change management and IT operations. Application controls operate within specific applications to help ensure that transactions and data processing are complete, accurate, authorised and valid.
Q8. Is TISAX only for automobile manufacturers?
No. TISAX is relevant to organisations across the automotive supply chain, including suppliers, engineering firms, software providers and service organisations that handle automotive information and are required by customers to demonstrate appropriate information security practices.
Q9. What is the difference between SOC 2 Type I and Type II?
SOC 2 Type I evaluates the design of controls at a specified point in time. SOC 2 Type II evaluates control design and operating effectiveness over a defined period. Type II therefore provides evidence of how controls operated during the examination period.
Q10. Can one audit satisfy multiple compliance frameworks?
A common audit programme can test controls that support several frameworks. However, one audit or certification does not automatically establish compliance with every framework. Framework-specific requirements, scope and evidence must still be assessed separately.
Q11. How often should an organisation conduct IT compliance audits?
Audit frequency depends on legal obligations, certification requirements, contractual commitments, business risks and internal governance policies. Organisations should follow applicable formal audit schedules and perform additional reviews when significant changes, incidents or risks arise.
Q12. What happens if an organisation fails an audit?
The result depends on the type of audit and the applicable framework. Findings may require corrective actions, additional evidence, follow-up testing or reassessment. In certification and attestation engagements, the outcome depends on the relevant certification body's or CPA firm's procedures and conclusions.
18. Conclusion
DPDPA, ISO/IEC 27001, GDPR, HIPAA, ITGC, TISAX and SOC 2 address different aspects of information security, privacy, regulatory compliance and IT governance. Organisations should first identify which frameworks apply to their business and then implement controls that address their actual risks and obligations.
A well-managed compliance programme should include documented policies, risk assessments, access management, data protection, security monitoring, incident response, backup and recovery, supplier management and regular internal reviews. Maintaining reliable evidence and tracking corrective actions are essential for demonstrating that controls are not only documented but also implemented and operating effectively.
Continuous compliance helps organisations protect sensitive information, improve operational reliability, meet customer expectations, reduce security risks and build trust with customers, partners and regulators.
