What is a Cybersecurity Internal Audit?

A Cybersecurity Internal Audit is a structured, in-depth review of an organization’s cybersecurity practices, systems, and processes. 

It is conducted by your internal IT team, a cybersecurity officer, or a third-party consultant like PKC Management Consulting

This audit assesses how effectively your organization is protecting its digital assets, data, and infrastructure.

Its key objectives are:

  • Identify gaps in cybersecurity defense mechanisms
  • Assess compliance with legal and regulatory requirements
  • Reduce risks of data breaches, ransomware, and insider threats
  • Strengthen operational resilience
  • Prepare for external audits such as ISO 27001, CERT-IN, or industry-specific inspections

Legal & Regulatory Compliance in India

In India, cybersecurity is a legal requirement. Failing to comply can lead to penalties, license suspension, lawsuits, or even criminal charges:

Here are the laws that set standards for cybersecurity audits in India:
